The dinner plate is spinning, the soup is bubbling, and one quick button press could rescue a busy evening. A compact microwave earns its counter space by making reheating, defrosting, and simple cooking feel refreshingly routine.
This roundup compares the best Microwaves under 100 across practical sizes, power ratings, finishes, and everyday controls. Keep reading to see which details deserve the most attention before you choose.
Key Takeaways
- Choose at least 700 watts for dependable reheating, while 900 watts offers faster results and better performance with larger portions.
- Check the interior capacity against your dishes, since a compact cavity may not fit wide dinner plates or casserole bowls.
- Look for one-touch presets and express-cook buttons if you value quick, straightforward operation.
- Prioritize a child safety lock and mute function if the microwave will sit in a family kitchen, office, or shared living space.
- Compare the external dimensions, turntable size, and door clearance before buying, because countertop space is rarely as generous as it looks.

Toshiba Microwave 0.9 Cu. Ft. 900W
For everyday reheating, this Toshiba gives you a useful middle ground with 0.9 cubic feet of capacity and 900 watts of power. That combination suits leftovers, frozen meals, beverages, and standard dinner plates without taking up the space of a full-size model.
The stainless steel finish gives it a practical, kitchen-friendly look, while the capacity provides more flexibility than the smallest compact microwaves. The limitation is a lack of listed details about presets, controls, mute functions, or safety features, so shoppers seeking specialized settings may need more information before choosing it.

Toshiba Microwave 0.9 Cu. Ft. Black Stainless
This Toshiba is a good fit if you want 900 watts of cooking power with a slightly more distinctive black stainless steel finish. Its 0.9-cubic-foot capacity offers room for routine meals, bowls, and plates while staying within the compact countertop category.
The dark exterior can coordinate well with black or mixed-metal appliances, and the mid-size interior is more versatile than a very small unit. However, the available listing does not identify specific presets, control features, or child-safety functions, which limits how precisely you can compare it with feature-heavy alternatives.

BLACK+DECKER Microwave 0.7 Cu. Ft. 700W
Choose this BLACK+DECKER model for a compact footprint and straightforward 700-watt performance. The 0.7-cubic-foot capacity works well in dorm rooms, offices, apartments, and kitchens where counter space is at a premium.
Its stainless steel exterior adds a cleaner, more finished appearance than basic black plastic, and the smaller cavity keeps the overall format practical for light daily use. The tradeoff is limited interior room and lower power than the 900-watt models, so larger dishes and faster reheating are less suitable here.
- Brand:BLACK+DECKER

- Capacity:0.7 cubic feet
- Wattage:700 watts
- Finish:Stainless steel

Chefman Microwave 0.7 Cu. Ft. 700W
Chefman packs a useful set of controls into this compact 0.7-cubic-foot microwave, including 10 power levels and six cooking presets. The one-touch express controls make frequent heating tasks simpler, while the mute button is especially useful in bedrooms, offices, or shared kitchens.
An eco mode and child safety lock add practical touches beyond basic heating, giving this model a broader feature set than many compact microwaves. Its honest limitation is the 700-watt output and smaller interior, which may feel slower or tighter for large portions.
- Brand:Chefman

- Capacity:0.7 cubic feet
- Wattage:700 watts
- Color:Black

The listed ECO mode adds a power-conscious option when the microwave is not in active use, and the black finish keeps the design understated. The limitation is that the available information does not list presets, power levels, or other control details, so its appeal rests mainly on size, simplicity, and efficiency.

- Capacity:0.7 cubic feet
- Wattage:700 watts

Frigidaire Microwave 0.7 Cu. Ft.
Frigidaire keeps this model focused on the essentials: a 0.7-cubic-foot interior in a simple black finish. It makes sense for a dorm, office, guest suite, or compact apartment kitchen where routine reheating matters more than a long list of settings.
The small format should be easier to place on a crowded counter, and the uncomplicated design can blend into many spaces. Still, the listing does not provide wattage or feature details, so you cannot assume the cooking speed, preset selection, or control layout from the title alone.
- Brand:Frigidaire
- Type:Microwave
- Capacity:0.7 cubic feet
- Color:Black
- Additional Feature:0.7-cu.-ft. interior
- Additional Feature:Compact countertop format

BLACK+DECKER Microwave 0.9 Cu. Ft. 900W
With 0.9 cubic feet of capacity and 900 watts of power, this BLACK+DECKER model gives you the room and speed needed for regular family-style reheating. It is a stronger fit than a 0.7-cubic-foot unit if you often heat full plates, larger bowls, or frozen entrees.
The stainless steel finish adds a polished appearance, while the 900-watt output supports quicker everyday cooking than lower-powered compact models. The available listing does not specify presets, power levels, or safety features, so its main strengths are size, power, and finish rather than documented extras.
- Brand:BLACK+DECKER
- Type:Countertop microwave
- Capacity:0.9 cubic feet
- Wattage:900 watts

Frigidaire Microwave 0.7 Cu. Ft. Black
This Frigidaire model suits a small-space setup, with a 0.7-cubic-foot capacity designed for basic countertop use. It is a sensible match for reheating individual portions, warming drinks, and handling lighter kitchen duties without demanding much room.
The black exterior has a low-key appearance that works well in offices, rental kitchens, and secondary food areas. The drawback is limited information about wattage and controls, so you should view this as a basic compact option rather than a model selected for specialized cooking programs.
- Brand:Frigidaire

Toshiba Microwave 0.7 Cu. Ft. 700W
Toshiba gives you a compact 0.7-cubic-foot design with 700 watts of power in this model. It works best for solo kitchens, break rooms, dorms, and other spaces where a microwave needs to handle daily basics without occupying valuable counter real estate.
The black finish keeps the look simple, and the smaller cavity is appropriate for mugs, bowls, and individual servings. Its limitation is capacity and power, both of which trail the 0.9-cubic-foot, 900-watt choices, while the listing provides no confirmed information about presets or safety controls.
- Brand:Toshiba
- Type:Countertop microwave
- Capacity:0.7 cubic feet
- Wattage:700 watts

For a microwave that contributes to the room’s look, this Frigidaire pairs a retro design with a distinctive black-and-gold finish. The 0.7-cubic-foot capacity and 700-watt output suit everyday reheating, while eight auto-cook menus reduce the need to choose settings manually.
The feature list also includes auto defrost, five power levels, an LED display, and a glass turntable, giving this compact model more documented functionality than several basic alternatives. Its limitation is the smaller interior and lower wattage, so large dishes and rapid cooking are not its strongest assignments.

- Capacity:0.7 cubic feet
- Wattage:700 watts
- Finish:Black and gold

Frequently Asked Questions
Is a microwave under $100 powerful enough for everyday use?
Yes. A model rated at 700 to 1,000 watts can handle common tasks such as reheating leftovers, cooking frozen meals, steaming vegetables, and defrosting food. Lower-wattage units may require longer cooking times, so follow package instructions as a starting point and stir or rotate food when recommended.
What size microwave fits a standard dinner plate?
Choose a unit with a turntable measuring about 12 inches if you regularly use large dinner plates. Interior capacity of roughly 1.0 cubic foot or more usually provides a more comfortable fit. Compact models can work well with smaller dishes, mugs, and bowls, but check the listed turntable diameter rather than relying on cubic-foot capacity alone.
Are countertop microwaves under $100 safe?
Yes, provided you install and use them according to the manual. Look for a certified safety label, adequate ventilation space, a secure door, and an intact power cord. Do not heat sealed containers, eggs in their shells, or unsuitable plastics. Use microwave-safe cookware, and supervise children who use the appliance.
Do inexpensive microwaves have a defrost setting?
Most models under $100 include at least one defrost function, usually based on time or food weight. Weight-based defrosting can be more convenient because it adjusts the cycle for the amount entered. For better results, pause to separate pieces and turn food during the cycle. Defrosted food should be cooked promptly rather than left sitting at room temperature.
How long should a budget microwave last?
A budget microwave may provide several years of service with regular cleaning, sensible loading, and proper ventilation. Lifespan varies with daily usage, construction, and how often the unit runs at full power. Clean spills promptly, keep the vents clear, and avoid slamming the door. If the door seal, latch, cord, or interior coating becomes damaged, stop using the microwave and consult the manufacturer.
