Best Microwaves Under $100

You don't need to spend a lot to get a reliable microwave. The models below are compact countertop units typically found for under $100. They cover the basics — reheat, defrost, a handful of power levels — without features you'll never use. Perfect for dorms, offices, guest suites, and tight counters.

• ✓ Aim for at least 700W — anything less takes noticeably longer to heat and may struggle with dense foods.
• ✓ A 0.9–1.0 cu ft interior fits standard bowls and plates; anything smaller may not spin a dinner plate.
• ✓ Turntable diameter matters more than capacity for large dishes — check it before buying.
• ✓ Manual dial controls are generally more durable than membrane touch panels at this price tier.
