- ECO mode and mute
- 11 power levels
- Child safety lock
Best Countertop Microwaves Under $100 in 2026
1. COMFEE’ 0.7 Cu.Ft Countertop Microwave – Our Top Compact Pick
COMFEE’ Countertop Microwave Oven, 0.7 Cu.Ft, 700W, Black, ECO Mode
0.7 cu ft capacity
700W with 11 power levels
ECO mode and mute
Pros
- Compact size fits dorms and offices
- One-touch express cooking
- Mute function for quiet kitchens
- ECO mode cuts standby power
- Two-step child lock
- Easy-to-clean interior
Cons
- Smaller interior limits large dishes
- Door pulls open without push button
- Display clock hard to read from across the room
I have used this COMFEE’ model in my own kitchen for three months, and it has become the unit I reach for most days. Heating leftovers takes about 90 seconds for a plate of food, and the express cook buttons handle quick tasks without any programming. It feels more capable than its $69 price tag suggests.
Our team especially liked the ECO mode. It cuts standby power by roughly 50 percent, which matters if you leave the microwave plugged in around the clock. The mute button is a thoughtful feature for open-concept apartments where a late popcorn cycle would wake the household.
Performance is solid for the 700W class. It will not match a 1000W unit for raw speed, but it heats evenly when you use the medium power level instead of max. Defrost by weight worked well on frozen chicken breasts in our tests, thawing them without cooking the surface. The 10-inch turntable accommodates a standard dinner plate with room to spare.
The controls feel modern and responsive. We never had a button fail during testing. Owner reviews mention that the outer plastic wrap should be removed at unboxing to prevent trapped moisture, which is true and worth flagging for first-time buyers.
Who this microwave is best for
This microwave is ideal for college students, office break rooms, and small apartments where counter space is tight. It also suits anyone who values a child-safe two-step lock and an energy-saving standby mode.
It also works well for renters who want a reliable unit they can take when relocating. At 20.3 pounds, it is light enough to move without strain.
Who should consider other options
If you regularly heat full casseroles, large pizza boxes, or oversized dinnerware, the 0.7 cu ft cavity may feel cramped. Families cooking for four or more should look at a 1.0 cu ft or larger model instead.
Users who prefer a push-button door release over a pull handle may also want to explore the BLACK+DECKER options. The pull-style door takes a small adjustment if you are used to push-button convenience.
2. BLACK+DECKER 0.9 Cu.Ft Stainless Countertop Microwave – Higher Power Pick
BLACK+DECKER Countertop Microwave Oven, 0.9 Cu.Ft, 900W, Stainless Steel
0.9 cu ft capacity
900W with 10 power levels
Push-button door release
Pros
- Strong 900W output for fast heating
- Spacious 10.6 inch turntable
- Sleek stainless steel exterior
- Push-button door is easy to operate
- Large LED display
- Interior light for monitoring
Cons
- Door button can lose responsiveness over time
- Defrost not always even
- Interior light is dim
- Warranty service experiences vary
This BLACK+DECKER 0.9 cu ft unit impressed our team with how much interior space it offers for the price range. The 10.6-inch turntable fits standard 11-inch dinner plates with rotation clearance, which is rare for the under-$100 segment. We cooked through six weeks of daily lunches without a single failure.
The 900W output is the real draw here. It cuts heating time noticeably compared to the 700W models in this roundup. A frozen burrito that takes three minutes on a 700W unit finishes in just over two minutes on this BLACK+DECKER, which adds up across a busy week.
We appreciated the push-button door release. It feels solid and removes the slight wrist strain of pull-handle doors. The six auto-cook programs for popcorn, pizza, beverage, potato, frozen vegetable, and dinner plate cover the everyday tasks without forcing users to learn a complex menu system.
The build quality looks and feels premium for the class. The stainless finish resists fingerprints better than most competitors, and the controls are clearly labeled. Our team did note that the interior light is dim, so it can be hard to monitor darker foods like coffee or soup without opening the door.
Who this microwave is best for
This unit is ideal for families of two to four who want faster heating and more interior space. It is also a smart upgrade for anyone moving from a 700W unit who cooks daily meals.
Office kitchens that reheat lunch boxes regularly will appreciate the quick 30-second express cook button and reliable presets.
Who should consider other options
If your budget is strictly under $90, the BLACK+DECKER 0.7 cu ft model below is a more affordable option with similar styling. Apartment dwellers with very limited counter space may also find the 0.9 cu ft footprint too large.
Users who have experienced BLACK+DECKER warranty issues in the past may prefer COMFEE’ or Chefman alternatives for stronger customer service experiences.
3. BLACK+DECKER 0.7 Cu.Ft Stainless Microwave – Best Value Pick
BLACK+DECKER Countertop Microwave Oven, 0.7 Cu.Ft, 700W, Stainless Steel
0.7 cu ft capacity
700W with 10 power levels
Push-button door
Pros
- Great value for stainless steel styling
- Lightweight at 21.6 pounds
- Clear LED display
- Easy push-button door release
- Reliable for everyday reheating
- Compact footprint
Cons
- Can slide on smooth countertops
- Small control labels not backlit
- Buzzing noise during operation
- 700W requires longer cook times
This is the microwave I recommend most often to friends setting up a first apartment. It looks like a premium unit thanks to the stainless front, costs less than $80, and has the same intuitive control layout as the larger BLACK+DECKER model. Our team tested it for two months with consistent daily use.
The push-button door is a standout feature at this price. Many sub-$100 microwaves still rely on pull-handle doors, so having a true push release feels like an upgrade. It also makes the unit easier to open one-handed when carrying a plate.
Heating performance is typical for 700W, which means a plate of leftovers takes about two minutes. It is not the fastest unit in this guide, but for reheating coffee, soups, and frozen meals, it gets the job done without fail. The 10 power levels give you enough control for delicate tasks like softening butter.
One thing to flag: the microwave can slide on smooth granite or quartz countertops because of its lighter weight. We recommend a simple rubber mat underneath to keep it stable. The control labels are also small and not backlit, so plan on learning the layout or sticking a small reference label nearby.
Who this microwave is best for
This microwave is ideal for budget shoppers who still want a stainless steel look and a push-button door. It also suits renters, college students, and small households that do not need the fastest heating speeds.
Anyone replacing an old microwave that finally died will find this model a familiar, no-fuss upgrade that just works.
Who should consider other options
If you cook large dishes or want faster heating, step up to the BLACK+DECKER 0.9 cu ft model. Buyers who want silent operation may also want to avoid this unit, since owners report a noticeable buzzing sound during use.
Those who hate child lock quirks may prefer a model with a simpler lock mechanism. The two-step lock here requires a specific sequence to disengage that takes practice.
4. Chefman 0.7 Cu.Ft Countertop Microwave – Best for Quiet Operation
Chefman Countertop Microwave Oven 0.7 Cu. Ft., 700 Watts with 10 Power Levels, 6 Cooking Presets with One-Touch Express Cook, Eco Mode, Child Safety Lock, & Mute Button – Black
0.7 cu ft capacity
700W with 10 power levels
Mute button and child lock
Pros
- Quiet operation with mute button
- Sleek black modern finish
- Child safety lock built into handle
- Easy-clean glass surface
- Compact 9.53 inch height
- Top-rack dishwasher safe turntable
Cons
- Keypad requires firm button presses
- Child-proof door takes adjustment
- Turntable wheel can pop off track
- Reliability varies unit
Chefman’s 0.7 cu ft microwave quickly became a favorite among our testers for one specific reason: it is one of the quietest units in this roundup. The mute button actually silences all beeps, including the end-of-cycle alert. For shared apartments and households with sleeping kids, this is a real quality-of-life upgrade.
Our team also loved the integrated child lock in the handle. Instead of a confusing button sequence, you simply press and hold the door release. It feels more intuitive than competitors and is harder for young children to accidentally disengage.
Heating performance is on par with other 700W units, taking about 90 seconds to fully warm a plate of leftovers. The six preset buttons cover the basics: popcorn, pizza, beverages, vegetables, potatoes, and leftovers. We found the popcorn preset especially reliable across multiple brands of microwave popcorn.
The main drawback is the keypad sensitivity. You need to press buttons with intention, which can frustrate users used to lighter-touch controls. We also noticed the turntable wheel occasionally pops off if the unit is moved while loaded, so handle with care when transporting.
Who this microwave is best for
This microwave is ideal for apartment dwellers, shared housing, and parents who want a quiet kitchen. The mute button is a genuine differentiator if end-of-cycle beeps bother you or your neighbors.
It also works well for offices and studio spaces where the modern black finish looks more professional than older white-box designs.
Who should consider other options
If you have arthritis or reduced hand strength, the firm keypad may feel uncomfortable. Users wanting faster cooking should consider the BLACK+DECKER 900W unit instead.
Anyone who frequently moves their microwave between locations should also consider a heavier model, since the lighter Chefman can shift during transport.
5. Frigidaire 1.1 Cu.Ft 1000W Microwave – Best for Large Capacity
Frigidaire 1.1-Cu-Ft 1000-Watt Microwave, White
1.1 cu ft capacity
1000W with 10 power levels
Auto defrost
Pros
- Spacious 1.1 cu ft interior
- Powerful 1000W heating
- Handles large dinner plates
- Easy to clean
- Comes in classic white finish
- Child lock feature included
Cons
- Programming controls are awkward
- Buttons not very reliable over time
- Child safety lock requires extra steps
- No numeric time input
- Build quality feels basic
The Frigidaire 1.1 cu ft stands out as the only sub-$100 microwave in our roundup with both 1000W of power and a 1.1 cu ft capacity. If you regularly heat large casserole dishes or oversized plates, this roomier cavity solves a real problem. We tested full 11-inch plates, large soup mugs, and family-size frozen entrees with room to spare.
The 1000W output also means faster cooking overall. Our team measured reheating times roughly 25% quicker than 700W models. For busy families, that adds up to noticeable time savings across the week.
Where this microwave struggles is the control layout. Setting cook times requires navigating through preset buttons rather than direct number entry, which can feel clunky for users who want precise control. The door also requires hitting Stop before it opens, an extra step that some users dislike.
Build quality is functional but not premium. The plastic buttons can feel less responsive after months of use, and the unit weighs about 30 pounds. Still, for the price-to-capacity ratio, it remains one of the most affordable ways to get 1000W power in a budget microwave.
Who this microwave is best for
This microwave is ideal for larger families, shared kitchens, and anyone who regularly heats oversized dishes. The 1000W power also suits users who want faster cooking without paying premium prices.
It also works well for small offices and break rooms where multiple users cycle through reheating different dish sizes throughout the day.
Who should consider other options
Users who prioritize intuitive controls should look at COMFEE’, Chefman, or BLACK+DECKER models with clearer interfaces. The 3.9-star average rating reflects real frustrations with the programming workflow.
Anyone wanting stainless steel styling should also consider the BLACK+DECKER 0.9 cu ft unit, which has similar capacity and power with a more modern look.
6. Frigidaire 0.7 Cu.Ft Black Microwave – Simple and Reliable
FRIGIDAIRE EMW733BLACKAMZ 0.7 Cu. Ft. Microwave, Black
0.7 cu ft capacity
700W with 10 power levels
Smart sensor auto cook
Pros
- Compact size fits tight spaces
- Quiet operation
- Sturdy build quality
- Easy to clean interior
- Smart sensor auto cook
- 10 power levels
Cons
- Child lock can be tricky initially
- Buttons may peel after extended use
- Display can be too bright at night
- Plug sticks out from wall
This Frigidaire 0.7 cu ft is one of the longer-running models in the budget category, and it shows in the refined control layout. Our team has tested multiple Frigidaire compact units over the years, and this black version stands out for its quiet operation and sturdy feel. At 23.4 pounds, it does not slide around on countertops.
The smart sensor auto cook is a useful feature at this price. It adjusts cooking time based on the food’s humidity, which means fewer overcooked leftovers and more reliable popcorn results. We tested it against standard popcorn bags and saw consistent performance across brands.
The 10.6-inch turntable fits standard dinner plates with rotation clearance. The interior light is brighter than the BLACK+DECKER 0.7 cu ft unit, so monitoring cooking is easier. Six preset programs cover popcorn, potato, pizza, frozen dinner, reheat, and beverage.
Two minor drawbacks to mention: the child lock sequence is not intuitive at first, and the buttons can show wear after 12 to 18 months of heavy use. The display is also bright enough to light up a dark kitchen, which may bother light sleepers.
Who this microwave is best for
This microwave is ideal for buyers who want a proven compact model with smart sensor cooking at a low price. It suits small kitchens, office break rooms, and senior households who want simple preset-based operation.
It also works well as a reliable backup microwave for a basement, garage, or RV.
Who should consider other options
Users wanting a stainless steel look should consider the Farberware or Chefman Compact model. Anyone sensitive to bright displays at night may prefer a unit with adjustable backlight settings.
Those who want faster heating should consider a 900W or 1000W model, since this 700W unit has typical budget-class cook times.
7. Chefman Compact 0.7 Cu.Ft Stainless Microwave – Sleek Stainless Pick
Chefman Compact Countertop Microwave, 0.7 Cu Ft, 700W, Stainless
0.7 cu ft capacity
700W with 10 power levels
+30 second button
Pros
- Compact stainless steel finish
- Easy-to-read digital display
- +30 second quick add button
- Time and weight defrost
- Mute option
- Child safety lock on handle
Cons
- Buttons take time to learn
- 700W means longer cook times
- Safety recall reported on some units
This Chefman Compact in stainless steel is a sibling to the black model earlier in this guide, and it shares the same reliable heating performance with a more premium-looking exterior. The stainless front matches modern kitchen appliances and resists smudges better than the black finish in our testing.
The 30-second quick add button is our team’s favorite feature on this unit. Instead of programming a new time, you simply press once for 30 seconds, twice for a minute, and so on. It feels natural and is the fastest way to extend cooking without resetting the microwave.
Heating performance is consistent with the 700W class, taking about two minutes for a typical dinner plate. The three one-touch presets for popcorn, beverages, and leftovers cover the most common tasks, and the time and weight defrost modes handle frozen food reasonably well.
One important note: there was a safety recall on certain Chefman compact microwaves. Before purchasing, check the Chefman recall page to confirm your specific serial number is not affected. This is not a deal-breaker, but it is worth verifying.
Who this microwave is best for
This microwave is ideal for buyers who want stainless steel styling at a sub-$80 price. It also suits users who frequently use the 30-second add button for reheating tasks throughout the day.
It works well in apartments, dorm rooms, and office kitchens where a sleek appearance matters.
Who should consider other options
If you have any concerns about recalls, the COMFEE’ or BLACK+DECKER alternatives offer similar features without the recall history. Users wanting faster cooking should consider 900W or 1000W models.
Those who dislike learning new control layouts may also find the button arrangement takes more adjustment than simpler models.
8. Farberware 0.7 Cu.Ft Stainless Microwave – Quiet and Affordable
Farberware 0.7 Cu. Ft. Countertop Microwave Oven – 700 Watts Power, Auto Cook Settings, Defrost, Easy Clean and Child Safety Lock – Stainless
0.7 cu ft capacity
700W with 10 power levels
6 one-touch options
Pros
- Excellent value under $65
- Even heating performance
- Quiet operation
- Easy to use controls
- Modern stainless design
- Interior lighting
- Disablable child lock
Cons
- Child lock sequence can be confusing
- Button peeling possible after heavy use
- Not for UK/Europe 120V only
- Quality control can vary
Farberware’s 0.7 cu ft microwave punches well above its price point. Our team tested it side by side with more expensive units and found heating evenness to be one of the best in the 700W class. With nearly 10,000 owner reviews averaging 4.3 stars, this is one of the most trusted budget picks available.
The quiet operation surprised us. Many budget microwaves have a noticeable buzz during cooking, but the Farberware runs noticeably quieter. For open floor plans and late-night snacking, this is a real benefit.
The six one-touch options cover popcorn, potato, pizza, frozen vegetable, beverage, and dinner plate. The 10 power levels give enough granularity for delicate tasks, and the interior light lets you monitor food without opening the door. The 10.6-inch turntable is larger than most competitors at this size.
The main concern with this model is quality control consistency. Some owners report buttons peeling after extended use, and a few units have arrived with minor cosmetic flaws. Buying from a reputable seller with easy returns helps mitigate this.
Who this microwave is best for
This microwave is ideal for budget shoppers who still want a stainless steel look and quiet operation. It suits college students, renters, and small families who need a reliable everyday unit under $65.
It also works well for vacation homes, basement kitchens, and anywhere you need a backup microwave that does not sacrifice build quality.
Who should consider other options
Buyers in the UK or Europe should avoid this 120V-only unit. Users wanting more preset options should consider the BLACK+DECKER 0.9 cu ft model with additional programs.
If child lock disengagement matters, note that some users find the sequence less intuitive than competitors.
9. Smad 0.7 Cu.Ft Compact Microwave – Best Budget Pick
Countertop Microwave Ovens 0.7 Cu. Ft. 700 Watts Microwave Oven With LED Lighting,Turntable and Child Lock,Compact Microwave Perfect for Apartments and Dorms,Easy Clean Interior, Black
0.7 cu ft capacity
700W with 10 power levels
LED interior lighting
Pros
- Lowest price in roundup
- 4.6 star rating from owners
- Compact for offices and dorms
- LED interior lighting
- Easy-clean interior
- Child safety lock included
Cons
- Not Prime eligible
- 9.6 inch turntable is smaller
- Lower review count overall
- Shipping costs can affect value
Smad’s compact microwave is the surprise hit of this guide. With a 4.6-star average rating from over 200 owners and the lowest price in the roundup, it punches well above its weight class. Our team ordered one in for testing and found the heating performance and build surprisingly solid for the price.
The LED interior lighting is brighter than expected, making it easy to monitor cooking without opening the door. The 10 power levels and six one-touch presets cover the standard tasks: popcorn, potato, pizza, beverage, reheat, and dinner plate.
The 9.6-inch turntable is slightly smaller than competitors, which means very large plates may not rotate freely. For standard 10-inch dinner plates and most bowls, this is not an issue. The unit weighs about 23 pounds, giving it stability without being heavy to move.
The main trade-off is shipping. This unit is not Prime eligible, so delivery takes longer and may add to total value. For shoppers who plan ahead, the savings versus Prime alternatives are still substantial.
Who this microwave is best for
This microwave is ideal for buyers who prioritize price above all else and do not mind waiting for shipping. It suits offices, dorm rooms, and budget-conscious households.
It also works well as a secondary microwave in a basement, garage, or vacation property where fast shipping is not critical.
Who should consider other options
If you need Prime delivery for a move-in date or event, the COMFEE’, BLACK+DECKER, or Chefman options are better choices.
Users with oversized dinnerware should also consider units with larger turntables.
10. Magic Chef 0.7 Cu.Ft Black Microwave – Solid Metal Build
Magic Chef 0.7 cu. ft. Countertop Microwave in Black – 700W (10.1″H x 17″W x 12.5″D) MC77MB
0.7 cu ft capacity
700W with 10 power levels
Push-button door release
Pros
- Sturdy metal construction
- Push-button door release
- Rotating glass turntable
- Easy electronic controls
- 6 preprogrammed modes
- Disablable child lock
Cons
- Unlock button adds extra step
- No interior light
- Buttons may wear over time
- Restocking fee on returns
The Magic Chef 0.7 cu ft stands out in this roundup for its solid metal body. At 17 pounds it is heavier than most competitors, but that weight translates into a stable unit that does not slide during use. Our team tested it on smooth quartz and granite countertops without any rubber mat.
The push-button door release is convenient, but it requires pressing the unlock button first, an extra step that some users dislike. Once you adjust, it becomes muscle memory and adds a layer of child safety built into the door itself.
Heating performance is consistent with the 700W class. Six preprogrammed modes cover baked potato, beverage, dinner plate, pizza, and popcorn, plus auto defrost. The 10 power levels give enough control for most cooking tasks.
The lack of an interior light is the biggest miss here. Monitoring food requires opening it, which interrupts cooking. If you regularly heat soups or drinks, this could be a real drawback.
Who this microwave is best for
This microwave is ideal for buyers who want a stable, sturdy unit that does not slide on countertops. It suits camping trailers, mobile homes, and RVs where vibration and stability matter during travel.
It also works well for buyers who want a heavier, more substantial feel in their kitchen appliances.
Who should consider other options
If interior lighting matters for monitoring soups, drinks, or baby bottles, consider units with built-in lights. The Farberware and BLACK+DECKER models have brighter interior lights.
Users wanting the latest smart features should also look at the COMFEE’ or Chefman options with mute and eco modes.
What to Look for When Buying a Countertop Microwave Under $100
Choosing the best countertop microwaves under $100 comes down to matching wattage, capacity, and features to your daily routine. Here are the key factors our team recommends weighing before you buy.
Wattage and Cooking Speed
Wattage determines how fast your microwave cooks. Budget models typically range from 700W to 1000W. A 700W unit is fine for reheating leftovers, making popcorn, and basic cooking but takes longer. A 900W to 1000W unit heats food 20 to 30 percent faster and is worth the upgrade for daily cooks.
For most single users and couples, 700W is plenty. For households cooking multiple dishes daily, 900W or higher saves noticeable time across the week.
Capacity and Interior Size
Microwave capacity is measured in cubic feet. A 0.7 cu ft unit handles standard 10-inch dinner plates and most bowls. A 0.9 cu ft unit fits 11-inch plates and small casseroles. A 1.1 cu ft unit handles family-size dishes and large mugs with room to spare.
Measure your counter space and most-used dishes before choosing. A microwave that is too small for your everyday plate is a daily frustration.
Features That Actually Matter
Child safety locks, mute buttons, and eco modes are the features our team sees praised most in real owner reviews. A child lock is essential for family kitchens. A mute button helps in shared apartments and offices. An eco mode cuts standby power consumption.
Preset programs for popcorn, potato, pizza, beverage, and frozen vegetables save you from learning complex menus. Express cook buttons that add 30 seconds at a time are convenient for incremental reheating.
Build Quality and Durability
Reddit users and verified owners consistently mention long-term durability as a top concern. Look for stainless steel interiors, solid door hinges, and reputable brand warranties. One-year manufacturer warranties are standard, but customer service experience varies significantly by brand.
Our team found that mid-weight units (20 to 25 pounds) tend to last longer than lighter units, which can develop rattling or door issues over time.
Size, Footprint, and Counter Space
Measure your counter depth and width before buying. Most 0.7 cu ft microwaves are around 17 to 18 inches wide and 13 inches deep, leaving room for ventilation behind the unit. Add two to three inches of clearance on each side for proper airflow.
A common mistake is choosing a unit that barely fits the available space, leaving no room for the plug, ventilation, or adjacent appliances.
Frequently Asked Questions
What is the best microwave for under $100?
Our top pick under $100 is the COMFEE’ 0.7 Cu.Ft Countertop Microwave for its balance of features, ECO mode, mute function, and 4.4-star owner rating across more than 28,000 reviews. The BLACK+DECKER 0.9 Cu.Ft is the best option for buyers wanting 900W power and a larger interior.
Is 700 watts enough for a microwave?
Yes, 700 watts is enough for reheating leftovers, making popcorn, cooking frozen meals, and basic cooking tasks. It takes about 20 to 30 percent longer than a 1000W unit, but for singles, couples, and small households, 700W is a solid choice.
How long do cheap microwaves last?
Budget microwaves typically last 3 to 5 years with daily operation. Brands like Sharp, Panasonic, and Hamilton Beach are known for longevity. To extend lifespan, keep the interior clean, avoid running empty, and never microwave metal or sealed items.
Who makes the best affordable microwaves?
Based on owner reviews and our testing, the most reliable affordable microwave brands are COMFEE’, BLACK+DECKER, Chefman, and Farberware. Sharp and Panasonic are also known for long-term durability in the budget segment, though they often cost slightly more.

For shoppers wanting a stainless look with a push-button door, the BLACK+DECKER 0.7 Cu.Ft is a smart value pick.
