Find the best countertop microwave under $100. Compare top-rated compact models with 700W power, easy controls, and trusted brands for dorms, apartments, and kitchens.
Ideal for: Renters, students, and apartment kitchens where space and power efficiency are priorities.
The Chefman stands out for its thoughtful engineering, particularly in how it addresses the universal frustration of child-lock door mechanisms. Owners consistently praise the intuitive handle design that manages safety without turning every microwave access into a puzzle. The 700-watt power is efficient enough for standard tasks (heating leftovers, warming beverages, making popcorn) without the energy overhead of larger units. The ten power levels give you precision that matters when you're softening butter or gently warming cream rather than blasting everything at full intensity.
One legitimate caveat: the keypad requires firm, deliberate presses, and several owners flagged this as exhausting if you're someone who adjusts settings frequently. You'll want the unit anchored against a wall so you're not wrestling with it sliding backward as you input commands. The 0.7 cubic-foot cavity is genuinely compact, so oversized dinner plates or tall containers may not fit without some creative angling. Compared to the Farberware models lower in this list, the Chefman's mute button and eco mode also give you quieter operation when household peace matters.
Built-in cETL safety certification and a solid one-year warranty reflect Chefman's focus on longevity at this price point. Most owners report consistent performance over months of regular use, and the dishwasher-safe turntable reduces cleanup friction.
Pros
Intuitive safety-lock design integrated into door handle
Mute button and eco mode for quieter operation
Even heating across standard portions and reheat tasks
Cons
Keypad requires firm, sustained pressure to register input
Compact 0.7 cu. ft. cavity limits oversized dishware fit
Key features
700 watts with ten selectable power levels for precise control
Six one-touch presets for popcorn, pizza, vegetables, and leftovers
Integrated child safety lock with easy pull-up handle release
Mute button and eco mode for energy-conscious cooking
Ideal for: Offices, break rooms, and households with frequent reheating and defrosting needs.
The Black+Decker delivers the kind of no-nonsense performance you'd expect from a brand that's earned shelf space in break rooms and kitchens for decades. The 0.7 cubic-foot interior and generous 10-inch turntable accommodate full-sized dinner plates and tall containers without the cramped feeling some compact units impose. Owners frequently praise how evenly it heats compared to smaller rivals, and the sensor presets genuinely deliver consistent results for popcorn and pizza without babysitting.
There are some real trade-offs worth considering. Several owners have reported that the unit slides on smooth counters: a safety concern that shouldn't be overlooked. The control labeling uses small, thin print on a black background, which means you may need better lighting to read buttons in dim kitchens. The venting fan also runs louder than competitors like the Comfee', something a handful of buyers found unsettling. Some units have also shown longevity issues; a few owners reported failures after six to seven months of regular use, which falls short of typical appliance durability expectations.
Where the Black+Decker excels is in sensor cooking accuracy and the size-to-power ratio for shared kitchens. If your counter is stable and labeling visibility isn't a concern, this remains a solid everyday performer. For shoppers who also browse microwaves at costco, the Black+Decker's widespread retail availability and consistent performance make it a reliable offline-purchase option too.
Pros
Large 10-inch turntable fits full dinner plates and tall containers
Sensor presets deliver consistent results for common tasks
Proven track record across tens of thousands of real-world uses
Cons
Unit slides on smooth countertops without anti-slip feet
Control labels in small print are hard to read in low light
Key features
700 watts with ten power settings and sensor-guided presets
10-inch removable glass turntable for even food rotation
Express one-touch buttons for 1–6 minute quick-start cooking
Large LED digital display with clock and countdown timer

Farberware
Farberware 0.7 Cu. Ft. Countertop Microwave Oven – 700 Watts Power, Auto Cook Settings, Defrost, Easy Clean and Child Safety Lock - Stainless
4.3(9,929)
Dependable 700W performer with defrost-by-weight feature and straightforward controls: solid everyday choice for modest budgets.
Farberware's stainless-steel model occupies middle ground in this lineup, offering practical versatility without frills. The defrost-by-weight setting genuinely simplifies thawing tasks: you enter meat mass rather than guessing time, which removes a frequent source of user frustration. The ten power levels, six presets, and memory function for custom settings give you enough customization to adjust cooking behavior to your habits. Owners generally report even, reliable heating for typical household tasks and a modern appearance that blends well with other appliances.
The primary concern Farberware owners flag is product consistency: multiple buyers noted that newer units differ subtly from earlier models in ways that diminish usability (turntable lip height, button sensitivity, power-level workflow). This isn't catastrophic, but it signals quality-control variability you won't find with the Comfee' model further down this list. A few owners also reported internal rusting or failure within two to three years, which is shorter than you'd ideally expect. Child-lock complaints are typical for the category, though Farberware includes easy-disable instructions.
If you land on this model, you're getting a trustworthy name and solid specs for the price. Just manage expectations that build consistency may vary between units.
Pros
Defrost-by-weight setting simplifies thawing frozen protein
Clean stainless-steel finish pairs well with kitchen decor
Memory function stores your preferred custom settings
Cons
Some newer units show quality-control inconsistencies vs. earlier versions
Reports of internal rusting or failure within 2–3 years of use
Key features
700 watts with ten power levels and six auto-cook presets
Defrost by weight or time: intuitive thawing for frozen foods
Memory function to save and recall your custom cooking settings
Stainless-steel finish with removable turntable and interior light
Ideal for: Noise-sensitive households, energy-conscious cooks, and small apartments where aesthetics matter.
The Comfee' distinguishes itself through thoughtful quiet-operation features that directly address real household friction. The mute button silences all beeps, and the energy-saving eco mode cuts standby power draw by half: small details that compound into measurable differences over months of daily use. The curved white design feels less utilitarian than the industrial boxes most budget microwaves resemble, and owners consistently mention aesthetic appeal as a pleasant bonus. Heating performance is solid for a 700-watt unit, with no significant complaints about uneven cooking or cold spots.
The compact interior is genuinely tight; if you regularly use oversized cookware or need to thaw large cuts of meat, this will frustrate you. The child-lock feature involves a two-step activation, which is safer but slightly more tedious than integrated designs like the Chefman's. One owner noted the turntable and ring felt flimsy: a durability concern worth monitoring, though most reviews don't echo this. At this price tier, the Comfee' delivers exceptional value, and many owners have reported zero issues after extended ownership.
Where it outshines the Chefman is in quiet, unobtrusive operation and overall design refinement. If you value a peaceful kitchen and modest space constraints, this is where your money goes furthest.
Pros
Mute function silences all beeping for quiet kitchen operation
ECO mode reduces standby power consumption by fifty percent
Curved white design looks more refined than typical compact models
Cons
Compact cavity limits oversized cookware and large protein thawing
Two-step child lock is safer but slightly more cumbersome to disable
Key features
700 watts with eleven power levels for nuanced heating control
Mute and eco modes for quiet, energy-efficient daily use
One-touch express buttons with +30-second quick-add function
Removable turntable and compact footprint ideal for tight counters

Farberware
Farberware 0.7 Cu. Ft. Countertop Microwave Oven – 700 Watts Power, Auto Cook Settings, Defrost, Easy Clean and Child Safety Lock - Black
4.2(6,840)
Entry-level 700W compact with core features and lower power draw: excellent for RVs, offices, and power-limited environments.
Ideal for: RV owners, off-grid homes, dorms, and tight budgets where lower power draw is essential.
This black Farberware model represents pure commodity-level pricing with no unnecessary extras. The 700-watt output is genuinely efficient: it will run on modest power budgets (ideal for RVs, off-grid cabins, or situations where breaker capacity is tight) without sacrificing core functionality. Owners consistently note it performs the fundamentals reliably: reheating leftovers, warming beverages, defrosting by weight or time. The ten power levels and six presets deliver enough customization for most household routines, and the child-lock mechanism includes straightforward disable instructions.
Likewise, the tradeoffs are clear and honest. Lower wattage means longer cook times for frozen dishes designed for full-power microwaves; you'll need to experiment or adjust recipes upward by 25-30 percent. The compact footprint means tall items and oversized plates won't fit without maneuvering. Some owners flagged durability concerns (interior rusting or door stickiness) though many others reported years of stable use. The loud, unsettling noise a few owners complained about hasn't surfaced in majority feedback, so individual unit variance may apply.
Compared to the Comfee' above, this Farberware trades quiet operation and eco smarts for absolute bottom-line affordability. Choose it if you're equipping a dorm, RV, or secondary kitchen where price is the deciding factor and you accept that performance will be serviceable rather than optimized.
Pros
Lower wattage draw suits RVs and power-limited installations
Defrost-by-weight and six presets handle routine cooking tasks
Entry-level pricing fits severe budget constraints
Cons
Longer cook times require recipe adjustment for frozen meals
Some owners reported interior rusting or door stickiness over time
Key features
700 watts with ten power levels and six preset auto-cook options
Defrost by weight or time setting for flexible frozen-food preparation
Compact 0.7 cu. ft. cavity with removable turntable and LED display
Lower power draw makes it suitable for RVs and limited circuits
How to Choose a Countertop Microwave Under $100
Four trade-offs that actually matter when matching a countertop microwave under $100 to your kitchen.
Wattage Matters More Than You'd Think
All five models here run 700 watts, which is the standard floor for compact microwaves in this price range. Understanding microwave wattage and capacity explained will clarify why 700W is efficient for apartments but slower for frozen dishes designed for 1000W+ units. Lower wattage reduces your power-bill footprint and works on older electrical circuits, which is why it appeals to RV owners and renters. The trade-off is longer heating times; plan on adding 20–30 percent extra time when reheating larger portions. If speed is non-negotiable, stepping up to a higher-wattage model (outside this budget) is the only remedy.
Interior Footprint: What Actually Fits?
The 0.7 cubic-foot cavity is the universal size in this category, but internal dimensions vary slightly. The Black+Decker's 10-inch turntable accommodates full dinner plates without crowding; the Chefman and Comfee' are noticeably tighter, with the Comfee' being most restrictive for oversized cookware. If you regularly microwave tall containers, large casserole dishes, or whole frozen steaks, measure your existing cookware against competitor specs before committing. Compact doesn't mean it won't work: it means you'll need to rotate or reposition items occasionally.
Noise and Quiet-Operation Features
The Comfee' stands alone with a dedicated mute button, while others rely on standard beep patterns. If you have sleeping family members, work night shifts, or simply value kitchen silence, the mute function is worth the slight premium. Some models also run a louder venting fan than others; the Black+Decker has been flagged for this by multiple owners. Read owner feedback on noise specifically if you're noise-sensitive: it's one of the few features that's hard to modify after purchase.
Child Safety Lock: Integrated vs. Two-Step
All models now include child-lock mechanisms per safety standards. The Chefman integrates it into the door handle (pull a specific way to open), while others use separate button sequences. Integrated locks feel less cumbersome for daily use but are harder to defeat if you don't have kids. Two-step locks are more traditional (press specific buttons or hold for three seconds) but more annoying if you're accessing the microwave constantly. Check the manufacturer's disable instructions before buying: most include them, but some require creative button combos you'll want to verify you can remember.
Defrost and Preset Functions
Defrost-by-weight (offered on both Farberware models) genuinely simplifies thawing: you enter meat mass instead of guessing time. Standard time-based defrost works too but is less forgiving. The presets (popcorn, pizza, potato, beverage, frozen veggie, reheat) are convenient shortcuts that mostly deliver consistent results. If you primarily reheat and defrost, presets are useful; if you cook creatively, the countertop microwave cleaning guide reminds you that manual time and power-level control offers more flexibility. Test a preset or two early to see if they match your habits.
Frequently asked
Quick answers to the questions readers ask most.
Can I use a 700W microwave for frozen dinners designed for 1000W microwaves?
Yes, but you'll need to increase cooking time by about 25–30 percent and watch for cold spots. Start by adding a quarter more time than the package suggests, then adjust based on results. Stirring halfway through helps distribute heat more evenly in lower-wattage units. For frequent frozen-meal users, a higher-wattage model outside this budget may be less frustrating.
Will a 700W microwave trip my breaker?
Not typically. Most modern circuits handle 15 amps at 120 volts, which equals roughly 1800 watts. A 700W microwave draws closer to 1000 watts actual input, leaving headroom. However, if your circuit is already carrying other appliances (coffee maker, toaster) simultaneously, you could overload it. RV and cabin users benefit most from the lower draw: these units run reliably on older wiring and small power systems.
How do I disable the child safety lock?
Every model in this guide includes disable instructions in the manual or on the unit itself. Most require pressing a specific button sequence (often 7 and 9, then holding the door-open button for three seconds) or pulling the handle in a particular way. Once disabled, the lock stays off even after unplugging. If you lose instructions, manufacturer websites or Amazon Q&A sections typically post the sequence.
Which model is quietest during operation?
The Comfee' is consistently praised for quiet operation, and its mute button eliminates beeping entirely. The Black+Decker runs a noticeably louder fan. The Chefman and both Farberware models fall in the moderate-noise middle. If sound matters, read owner reviews specifically mentioning noise before committing.
What's the typical lifespan of a budget-priced microwave?
Most owners report 3–5 years of reliable use, though longevity varies by unit. The Comfee' and Chefman have fewer durability complaints in recent reviews, while some Farberware models have shown rusting or failure within 2–3 years. Proper ventilation (leaving clearance around vents) and avoiding steam accumulation extend lifespan. Don't expect a 10+ year appliance at this price; it's a temporary kitchen workhorse.
