A cold plate turns slowly beneath the microwave’s soft hum, while dinner waits for heat that arrives too slowly or unevenly. For small kitchens, dorm rooms, offices, and quick weekday meals, a compact microwave can make the difference between a practical meal and a sad snack.
This roundup compares the best Microwaves oven under $100, with attention to capacity, wattage, controls, and everyday convenience. Keep reading to see which specifications deserve the closest look.
Key Takeaways
- Choose 900 to 1,000 watts for faster reheating and more consistent cooking, especially with larger portions.
- Select 0.7 cubic feet for tight spaces, but confirm that your preferred plates and bowls will fit inside.
- Look for 10 power levels if you frequently defrost meat, soften butter, or heat delicate foods.
- Prioritize one-touch presets for quick meals, while a mute button and eco mode can make daily use more pleasant.
- Check the turntable and exterior dimensions before buying, since interior capacity alone does not show how much counter space the microwave needs.

The stainless steel finish works well beside other appliances, and the size should handle routine plates, bowls, and beverages. Because the listing does not provide control or preset details, this model is best considered for its core capacity, power, and finish rather than advanced programming.

Frequently Asked Questions
How many watts should a microwave under $100 have?
For everyday reheating and cooking, look for at least 800 watts, with 900 to 1,000 watts offering faster, more even results in many cases. A 700-watt model can still work well, but packaged cooking instructions may need extra time. Follow the microwave's manual rather than adding time randomly. Lower-power models may need adjustments, especially for frozen meals, dense foods, and recipes written for higher-wattage appliances.
What size microwave fits a dinner plate?
A microwave with around 0.9 to 1.1 cubic feet of interior space often fits a standard dinner plate, but the turntable diameter matters more than the capacity listed on the box. Look for a turntable of at least 11 inches if large plates are part of your routine. Measure your plate, including handles or raised edges, and compare that measurement with the product specifications. A larger exterior does not always mean a larger usable interior, because insulation and motor components take up space.
Are inexpensive microwaves safe to use?
A microwave under $100 can be safe if it has an intact door, proper ventilation, and certification from a recognized safety organization. Check for a secure door seal, a grounded power cord, and clear instructions before using the appliance. Do not operate a damaged unit or defeat its door latch. Use only microwave-safe containers, keep the interior clean, and follow the recommended clearance around the vents.
Do microwaves under $100 have a warranty?
Many include a one-year limited warranty, though coverage differs by brand and may exclude cosmetic damage, misuse, or shipping problems. Read the warranty terms before buying, especially the rules for service, replacement, and return shipping. Keep the receipt, model number, and purchase confirmation. Also check the retailer's return window, since returning a faulty appliance through the seller may be simpler than arranging warranty service.
Can I install a countertop microwave inside a cabinet?
Usually, no. A countertop model needs air circulation around its vents, while an over-the-range or built-in microwave is designed for a specific installation method and may require electrical or ventilation work. Follow the manufacturer's clearance requirements exactly. If the instructions do not approve enclosed cabinet placement, keep the microwave on an open countertop rather than turning a ventilation problem into a kitchen renovation.
