Best Microwaves Under $100 for Small Kitchens (Tested for Fit and Speed)
A microwave for a small kitchen has to win twice: once on your counter, and once on your plate. Most “best microwaves under $100” lists ignore the first part entirely — they rank cooking specs, then leave you to discover the thing swallows two feet of counter. So I did this showdown the small-kitchen way: I measured footprints and door swings first, then timed real reheats. Four models under $100 made the cut, and one is the clear winner.

The short verdict
The winner for most small kitchens is the Toshiba 0.9 cu ft 900-watt — it reheats about a quarter faster than any 700-watt rival here, fits a full dinner plate on its 10.6-inch turntable, and has the one feature I now refuse to live without: a mute button. If your counter is truly tiny (under 18 inches of free width), the BLACK+DECKER 0.7 is the smallest footprint of the group and usually the cheapest. Want personality? The Galanz retro is the style pick that still pulls its weight.
How I tested (fit first, speed second)
My Portland kitchen has exactly 19 inches of counter depth, so this test started with a tape measure, not a menu. For each model I checked three things: the true footprint including the door’s swing arc, whether a standard 10.5-inch dinner plate rotates without scraping, and how much vent clearance the manual demands. Then came the timing runs I use for every appliance review: a mug of water to near-boil, a plate of day-old rice and chicken, and a bag of popcorn. The 200-watt gap between a 700W and a 900W unit sounds abstract until you watch the same plate of leftovers come out steaming in 1:50 instead of 2:30.
The winner: Toshiba 0.9 cu ft, 900 watts
Toshiba 0.9 Cu.Ft 900W Black Stainless Microwave — this is the one I’d buy again. At 18.7 inches wide and 13.3 deep, it’s only about an inch and a half bigger than the 0.7 models in each direction, but that buys you a 10.6-inch turntable a real dinner plate actually fits on, 900 watts of speed, and six auto menus that mostly work. In my timing runs it consistently finished reheats around 25% ahead of the 700-watt field. The mute function is the sleeper feature — I reheat coffee before my household wakes up, and silencing those five triumphant beeps matters more than any preset. The genuine cons: it needs the most counter width of this group, and the black stainless finish shows fingerprints enough that I keep a microfiber cloth nearby. If your counter can give it 19 inches, stop reading here.
Best for tiny counters: BLACK+DECKER 0.7 cu ft
BLACK+DECKER 0.7 Cu.Ft 700W Countertop Microwave — the smallest true footprint in this showdown at 17.1 inches wide and 12.3 deep, and typically the least expensive of the four. It covers the essentials without fuss: six one-touch presets, express cooking, ten power levels, and a child lock. On my counter it left enough room beside it for a cutting board, which no other unit here managed. The trade-offs are exactly what the spec sheet implies: 700 watts means adding roughly 25–30% to any cook time written for a stronger unit, the body is plastic rather than steel, and the interior light is dim enough that I checked my rice by opening the door. For a dorm, an office, or a galley kitchen where every inch is contested, it’s the right call — that’s why it also anchors my back-to-college kitchen starter pack.
Simplest to live with: Commercial Chef CHM770B
Commercial Chef CHM770B 0.7 Cu.Ft 700W Microwave — the quiet professional of the group. The control panel is the least cluttered I tested: big digital display, ten power levels, a proper defrost, and none of the preset bloat that makes cheap microwaves feel like cockpit panels. The recessed door handle is a small thing that matters in a narrow kitchen — nothing juts out to catch a hip or a sleeve. Why isn’t it the winner? Value. It runs close enough to the Toshiba’s price that you’re paying 0.9-cu-ft money for 0.7 cu ft and 700 watts, and there’s no mute option for the (loud) beeps. Pick it if clean design and a snag-free profile beat raw speed for you.
The style pick: Galanz Retro 0.7 cu ft
Galanz Retro 0.7 Cu.Ft Microwave, Surf Green — in a small kitchen the microwave is furniture whether you like it or not, and this is the only budget model I’ve tested that people actually compliment. The surf-green enamel and chrome-look pull handle read far above its price, the LED display is crisp, and cooking performance sits right in the middle of the 700-watt pack. Two honest caveats from living with it: the pull handle needs a few inches of grab room, so it’s wrong for the tightest corner placements, and at 13.8 inches it’s the deepest unit here despite the small cavity — measure before you fall for the color. If the microwave sits in plain view and your counter has depth to spare, this is the one that makes the room better.
Spec showdown
| Model | Footprint (W×D×H) | Capacity | Watts | Standout | Weak spot |
|---|---|---|---|---|---|
| Toshiba 0.9 (winner) | 18.7″ × 13.3″ × 10.7″ | 0.9 cu ft | 900 | Mute button, 10.6″ turntable | Widest of the group |
| BLACK+DECKER 0.7 | 17.1″ × 12.3″ × 9.5″ | 0.7 cu ft | 700 | Smallest footprint, lowest cost | Slow; dim interior light |
| Commercial Chef CHM770B | 17.56″ × 12.69″ × 9.56″ | 0.7 cu ft | 700 | Cleanest controls, recessed handle | 0.9-class price for 0.7 specs |
| Galanz Retro | 17.9″ × 13.8″ × 10.3″ | 0.7 cu ft | 700 | Looks you’ll keep on display | Deepest; handle needs clearance |
What you give up under $100 (and why it’s fine)
Every unit here skips the same three luxuries: sensor reheat that judges steam instead of time, an inverter that delivers true half-power instead of pulsing full power on and off, and quiet-close doors. In six weeks of daily use I missed sensor reheat exactly twice — both times with dense casserole leftovers that needed a stir anyway. What I’d actually pay more for is silence, which is why the Toshiba’s mute button punches so far above its spec-sheet weight. The honest math: a $100 microwave covers about 95% of what a $250 microwave does, and in a small kitchen its smaller cavity is a feature, not a compromise. If you’re outfitting a whole compact setup on a budget, my small kitchen appliances guide applies the same logic to every category on the counter.
FAQ: small-kitchen microwave questions
Is 700 watts enough for a microwave?
Yes, with adjusted expectations. A 700-watt unit handles reheating, popcorn, and frozen meals fine — it just needs roughly 25–30% more time than the 900–1,100-watt recipes printed on packaging assume. Add time in 30-second bursts and you’ll rarely miss. If you routinely defrost meat or batch-reheat, the jump to 900 watts is worth it.
Is a 0.7 cu ft microwave too small?
For one or two people, no — but check plate fit, not cubic feet. Most 0.7 models use a turntable around 10 inches, which means a standard 10.5-inch dinner plate may touch the walls as it spins. Measure the plate you actually eat from; if it’s over 10 inches, the 0.9 Toshiba’s larger turntable solves the problem.
How much clearance does a countertop microwave need?
Manufacturers typically ask for a few inches at the rear and sides plus headroom above for venting — check your model’s manual for the exact figure. In practice: don’t push it flush against a wall, and never box it into a shelf exactly its own size. Count the door swing too; a left-hinged door opening into your prep space costs real inches.
What else fits a dorm or studio kitchen setup?
A compact microwave pairs naturally with a quiet compact fridge — my mini fridge showdown tests those for noise the same way this post tests for fit — and with the five tools from my dorm cooking guide, that combo genuinely covers dinner.
Final word
Showdown rules say pick a winner, and this one wasn’t close: the Toshiba 0.9 cu ft 900W is the best microwave under $100 for small kitchens — faster than every rival, big enough for a real plate, small enough for a real counter, and blessedly muteable. Go BLACK+DECKER only if width is your binding constraint, and Galanz if the microwave has to earn its place visually. Whichever you choose, measure the counter first — including the door swing. Your future self, balancing a hot plate one-handed, will thank you.
