A cheap microwave should heat your leftovers evenly, fit on a cramped counter, and survive a dorm move without costing a week’s grocery budget. But the budget aisle is full of units that scorch the edges while leaving the center cold or buzz like a dying fan on every reheat cycle. Sorting the genuinely capable compact ovens from the frustrating duds means looking past sticker shock at the real engineering that matters in this price bracket.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This buying guide is grounded in hundreds of hours of cross-referencing real owner experiences and spec-sheet data to identify which low-cost microwave models actually deliver reliable, even cooking without the annoyance.
Whether you are outfitting a dorm room, a small apartment, or just need a secondary unit for the office, my goal is to point you toward the best cheap microwave options that balance wattage, footprint, and daily usability without hidden headaches.
How To Choose The Best Cheap Microwave
Budget microwaves share one thing: a tight bill of materials. The winner is not the one with the most features, but the one that gets the fundamentals right — consistent magnetron output, a properly sized turntable, and a control interface that survives daily abuse. Here are the three specs that separate a smart buy from a regret.
Wattage vs. Cooking Speed
Every cheap microwave in this range runs between 700W and 900W. The difference is about one minute per cup of water. A 700W unit boils a cup in about two and a half minutes; a 900W unit does it in under two. For frozen meals and leftovers this delta matters less, but if you regularly heat a 12-inch pizza or a large casserole dish, the extra 200W translates to noticeably more even heating across the center. Do not assume higher wattage always wins — some 700W models have better magnetron placement that avoids cold spots better than poorly designed 900W units.
Turntable Diameter and Interior Height
A 9.6-inch turntable fits standard dinner plates but struggles with rectangular containers or tall mugs. Look for a 10.6-inch turntable (common in 0.9 cu. ft. models) if you frequently reheat takeout boxes or soup bowls. Interior height is equally critical — most cheap microwaves have a ceiling just over 8 inches, which is too low for a standard coffee mug with a handle. If you drink from tall 16oz mugs or heat wide pasta bowls, prioritize models with at least 10 inches of internal clearance.
Button Quality and Lock Mechanic
The physical interface is where cost cutting shows most. Cheap rubber membranes wear out in months; mechanical buttons with positive click feedback last years. Also check the child lock activation sequence — a lock that requires holding a button for three seconds is far less annoying than one buried in a confusing menu. The door latch mechanism on budget microwaves tends to fail first. Look for models with a steel latch reinforcement or the lift-to-open safety design that avoids the jam-prone push-button found on many entry-level units.

In‑Depth Reviews
1. TOSHIBA ML-EM09PA(SS) Small Microwave Oven
The TOSHIBA ML-EM09PA(SS) sits at the top of this list because it delivers the best combination of interior room, heating power, and control usability among budget-friendly models. The 900W output tested at a measured 903W per one customer, meaning the magnetron actually delivers its rated spec — rare in this price tier. The 0.9 cu. ft. cavity and 10.6-inch glass turntable accommodate a 12-inch frozen pizza or a tall soup bowl with room to spare, and the stainless steel interior wipes clean without staining.
Six preset menus cover popcorn, pizza, potato, reheat, beverage, and frozen vegetables, while 11 power levels give fine-grained control for everything from softening butter to boiling liquids. The two-step child lock is clear and simple — no digging through menus — and a mute function silences the end-of-cycle beeps that wake up roommates or napping kids. Owners consistently note that food heats evenly, with no scorched edges or icy centers, which is the biggest complaint across cheaper 700W units.
The main drawback is audible fan noise — several users call it louder than expected during operation. The exterior dimensions (18.7 x 14.7 x 10.7 inches) also mean it needs proper counter space; it is not the most compact option. For anyone who wants a near-premium experience without crossing into premium pricing, this Toshiba is the model to beat.
What works
- Measured 900W output with uniform heating
- Large 10.6-inch turntable fits full plates
- Simple child lock and mute function
- Easy-clean stainless steel interior
What doesn’t
- Fan noise is above average during operation
- Requires decent counter footprint
- Display only shows time, not power level
2. Farberware 0.7 Cu. Ft. Countertop Microwave Oven
Farberware’s 0.7 cu. ft. model is one of the most consistently praised cheap microwaves for a simple reason: it does not annoy you. The 700W output is adequate for standard reheating and frozen meals, but the real win is the noise profile. Multiple owners report it runs quieter than previous microwaves they owned, with a soft humming magnetron and a beep that is loud enough to hear but not jarring.
Ten power levels and six one-touch presets (popcorn, potato, pizza, beverage, frozen vegetable, reheat) cover the daily basics without overwhelming the interface. The defrost function works by weight or by time, and the LED display and interior light make monitoring easy. The stainless steel finish and black trim look more expensive than the price suggests, and the easy-clean interior resists baked-on splatters.
The child safety lock is standard, though a few users find the lock activation sequence slightly inconvenient if you open the door frequently. The 9.6-inch turntable fits standard plates but struggles with larger rectangular dishes. Overall, this is a dependable, drama-free microwave that prioritizes quiet operation and reliable controls over flashy features — exactly what a secondary kitchen unit should be.
What works
- Quieter operation than most budget microwaves
- Straightforward buttons with positive feel
- Cooks food evenly with no cold spots
- Attractive stainless steel build
What doesn’t
- 9.6-inch turntable limits large dish sizes
- Child lock can be slightly finicky
- 700W is slower for large dishes
3. BLACK+DECKER Compact Countertop Microwave Oven
BLACK+DECKER owns the reputation for making small microwaves that actually survive the abuse of dorm life, van conversions, and cramped office break rooms. This 0.7 cu. ft. white model is handless — a sleek, push-to-open front that looks clean but draws mixed feedback. At 700W it is on the slower side, boiling a cup of water in about two and a half minutes, but the trade-off is low power consumption that works well with generators and RV inverters.
Interior dimensions are 14.2 x 12.8 x 8.1 inches with a 10-inch turntable — slightly larger than the typical 9.6-inch plate found in other 0.7 cu. ft. models, which means it fits a standard dinner plate without scraping the edges. The LED interior lighting is bright and the child lock is a simple push-button release, though a few owners note the rubber feet lack grip and the unit slides on smooth counters when you press the door release.
Customer feedback is overwhelmingly positive for reliability, but the mirror image downsides are real: the unit is very small, and if you need to reheat a large casserole dish or a full-size pizza, this is not your machine. The door latch has also been flagged occasionally for becoming stubborn after months of use. For a true space-saving secondary microwave where dependability matters more than speed, this Black+Decker earns its spot.
What works
- Reliable brand with consistent owner satisfaction
- 10-inch turntable for its size class
- Low power draw ideal for RV/van setups
- Simple, easy-to-use control interface
What doesn’t
- Feet lack grip, slides when opening door
- Very small footprint limits dish options
- Door latch reported to stiffen over time
4. Smad Countertop Microwave Oven 0.9 Cu. Ft. 900W
The Smad 0.9 cu. ft. 900W model punches above its weight by offering the same cavity size and wattage as the top Toshiba but with a unique lift-to-open safety door design. Instead of a traditional push-button latch, you press upward on the handle edge to release the door — a mechanism that avoids the common jam-failure point on cheap microwaves and adds genuine child safety without a complicated lock sequence.
Six auto menus, 10 power levels, multi-stage cooking, and defrost by weight or time cover every standard cooking task. The 10.6-inch glass turntable handles a 12-inch pizza or a full rotisserie chicken, and the interior is described as easy to clean with no stubborn grease buildup. At 25 pounds it is heavier than most 0.9 cu. ft. models, which actually translates to a more solid feel — the door closes with a reassuring thud rather than a hollow rattle.
The main complaints center on the black finish showing fingerprints easily and the LED display being slightly dim in bright rooms. A few owners also note that the memory function is not intuitive without reading the manual. But for sheer value — 900W power, generous interior, and a door that will not jam — this Smad is a compelling alternative that deserves consideration.
What works
- Unique lift-to-open door avoids latch jams
- Full 900W power with even heating
- Large 10.6-inch turntable fits big dishes
- Solid, premium-feeling build weight
What doesn’t
- Black finish shows fingerprints and smudges
- LED display can be hard to read in sunlight
- Memory function requires reading the manual
5. Chefman Compact Countertop Microwave Oven 0.7 Cu. Ft. 700W
Chefman’s entry in the budget microwave arena is defined by two features that matter more than most people realize: a mute button to kill the beeping and a child safety lock that is genuinely easy to operate. At 700W and 0.7 cu. ft., it does not try to be a powerhouse, but for a dorm room or a night-owl kitchen where silence matters, this microwave delivers exactly what it promises.
Three presets (popcorn, beverages, leftovers) keep the interface simple, and the +30 seconds button lets you add time mid-cycle without cycling through menus. Ten power levels give you control from melting chocolate to rapid boiling, and the defrost function works by time more reliably than some competitors’ auto-defrost. The stainless steel exterior wipes clean easily and the 12.93-inch depth is among the shallowest in this category, fitting on tight counter strips near the sink.
Owners report that the door latch, while not a push-button opener, requires a firm pull at the top edge — some find it less convenient than a traditional handle. A few also note that the interior lighting is dim compared to pricier models. But for the price, the combination of a mute option, easy child lock, and compact footprint makes this the smartest choice for anyone who prioritizes quiet and simplicity over raw power.
What works
- Mute button completely silences beeps
- Simple child lock, easy to toggle
- Shallow depth fits tight counters
- Good heat distribution for a 700W
What doesn’t
- Door requires a firm lift to open
- Interior light is dimmer than average
- No push-button door release
6. Emerson MW7601SL Countertop Microwave Oven
The Emerson MW7601SL turns heads with a fully mirrored glass door that reflects light and makes a small kitchen look larger. For buyers who care about appliance aesthetics on a strict budget, this is the only model in the list that makes the microwave a visual feature rather than an eyesore. At 700W and 0.7 cu. ft. the cooking performance is standard for the tier, but the design language pulls it ahead of generic beige boxes.
Ten power levels and six pre-programmed settings (popcorn, potato, pizza, beverage, frozen vegetable, reheat) cover the essentials, and the defrost function works by both time and weight. The LED display is clear and the digital clock is handy for keeping track of time while cooking. The white interior makes it easy to spot spills before they bake on, and the overall weight is light enough to move between kitchen and dorm room without strain.
The mirrored control panel has a real flaw: in bright sunlight or under direct overhead kitchen lights, the reflective surface makes the touch labels nearly invisible. The touch panel itself has a cheap, ripply feel that lacks the satisfying click of physical buttons. One owner reported the door latch jamming after a few months — though this is an outlier among mostly positive reviews. If visual appeal is your top priority and you can live with a finicky interface, this Emerson delivers the best looks in the cheap microwave segment.
What works
- Mirrored door is genuinely eye-catching
- White interior easy to keep clean
- Lightweight and portable
- Good range of presets
What doesn’t
- Mirror control panel unreadable in bright light
- Touch interface feels cheap and not backlit
- Occasional door latch reliability concerns
7. Smad Countertop Microwave Oven 0.7 Cu. Ft. 700W
This Smad 0.7 cu. ft. model is the most affordable entry in the lineup, built for the buyer who needs a functional microwave and nothing more. At 700W and with a narrow 17.9-inch width, it slides into the tightest gaps — think apartment galley kitchens, RV counters, or a shelf in a cube farm break room. The black finish is low-profile and the button interface is straightforward plastic membrane, no touchscreen complexity.
The feature set is basic but complete: 10 power levels, six one-touch presets (popcorn, potato, pizza, beverage, frozen vegetable, reheat), defrost by weight or time, an LED display with clock and timer, interior lighting, and a child safety lock. The 9.6-inch glass turntable is small but works fine for standard plates and bowls. Owners consistently note that it feels well built for the price and that the child lock is easy to engage without hunting for a manual.
Where this microwave falls short is the same place all 700W budget models do: slow heating of large items and occasional unevenness. The 0.7 cu. ft. cavity also means a 12-inch pizza will not fit without cutting it in half. A few owners also note that the keypad membrane is not backlit, making it hard to read in dim light. For the absolute lowest entry point into a reliable microwave that does not break in a month, this Smad is the sensible, no-regret choice.
What works
- Narrowest footprint for super-tight counters
- Simple interface with no learning curve
- Easy child lock activation
- Surprisingly solid build feel
What doesn’t
- 700W is slow for large dishes
- 9.6-inch turntable is small
- Membrane buttons not backlit
Hardware & Specs Guide
Magnetron Wattage and Cooking Consistency
The magnetron is the heart of any cheap microwave. A 900W unit delivers roughly 30% more microwave energy per second than a 700W unit, translating to faster heating and better penetration into dense foods like thick casseroles or whole potatoes. However, wattage alone does not guarantee even heating — the position of the waveguide, the stirrer fan design, and the turntable rotation pattern determine whether the magnetron’s energy hits the food uniformly. Some 700W models with well-placed waveguides outperform poorly designed 900W units in cold-spot testing, so prioritize owner feedback about even cooking over raw wattage figures.
Turntable Diameter and Cavity Floor Space
Turntable size directly dictates what dishes fit. A 9.6-inch turntable (standard in 0.7 cu. ft. models) fits 8-inch dinner plates and standard cereal bowls, but rectangular takeout containers and 12-inch pizza slices overhang and snag on the cavity walls. A 10.6-inch turntable (found in 0.9 cu. ft. models) clears a full dinner plate with a 2-inch gap on each side and easily accommodates a 12-inch frozen pizza on its glass surface. Always measure your most-used cookware before buying — a cheap microwave that cannot fit your microwave-safe pasta bowl will frustrate you daily.
