A microwave is the workhorse of the modern kitchen, handling everything from quick defrosts to full meals in minutes. But finding the right one under $100 can feel like a gamble—too many models promise convenience but deliver uneven heating or clunky controls. I spent weeks testing a range of affordable options, focusing on real-world performance, ease of use, and durability.
Designed with budget-conscious home cooks and small-space dwellers in mind, these aren't just basic reheating boxes. The key differentiator is how each model balances power, features, and footprint. From smart sensors that take the guesswork out of cooking to retro aesthetics that double as decor, the best microwaves under $100 prove you don't need to spend a fortune for reliable results.
It's worth considering your specific needs: counter space, wattage for faster cooking, and whether you want extras like mute functions or child locks. For families, a larger capacity with auto menus is a game-changer, while compact options fit dorm rooms or offices perfectly. I also looked at replacement parts and accessories, because even the best microwave needs maintenance over time.
Overall, the TOSHIBA EM131A5C-BS Countertop Microwave stands out as the most versatile performer, combining 1000W power with a smart humidity sensor and 12 auto menus for effortless cooking. Its sleek black finish and easy-clean interior make it a top pick for any kitchen. Read on for full reviews.

"A stylish retro microwave that brings personality to your kitchen without breaking the bank"

In testing, the 700-watt power handled reheating leftovers and defrosting small items adequately, but it took noticeably longer than higher-wattage models for tasks like cooking frozen meals. The 8 auto menus for popcorn, pizza, and beverages worked reliably, and the glass turntable ensured even heating. The child safety lock is a nice addition for households with young kids, though the small 0.7-cubic-foot capacity means you won't fit a dinner plate or large casserole dish.

For under $10 for a two-pack, this is an excellent value for anyone needing a quick replacement. They are ideal for budget-conscious users or as a backup set, but those seeking heavy-duty durability may prefer pricier OEM options. Overall, a solid choice for basic microwave maintenance.

FAQ
What are the best microwaves under $100?
The best microwaves under $100 balance power, size, and smart features without breaking the bank. Top picks include the TOSHIBA EM131A5C-BS with 1000W and a smart humidity sensor, and the Emerson MWR7020BL for its retro style and compact 700W performance. We also found that accessories like replacement filters and mica sheets can extend the life of your existing unit, making them smart budget buys.
How do I choose a microwave under $100?
Start by measuring your counter space and deciding on wattage—1000W models like the Toshiba cook faster, while 700W units like the Emerson are fine for reheating. Consider your cooking habits: if you defrost or cook from scratch often, look for auto menus and a humidity sensor. For families, a child-safe lock is a must, and for kids, a toy microwave like the Cuterabit can be a fun, safe introduction.
What features matter most in a budget microwave?
Wattage is king—1000W ensures even cooking, while 700W is slower but sufficient for simple tasks. Smart features like a humidity sensor and 12 auto menus (found on the Toshiba) add convenience without extra cost. Don’t overlook build quality: a removable turntable, easy-clean interior, and mute function (like the Toshiba’s ECO mode) make daily use much more pleasant.
What price should I expect for a decent microwave under $100?
You can find reliable countertop models between $60 and $100, with 700W compact units often at the lower end and 1000W feature-rich models at the higher end. Accessories like the Fetechmate grease filters or universal mica sheets cost under $20 and are great for repairs. The Cuterabit toy microwave is around $30, making it an affordable gift.
Are expensive options worth it if I’m on a tight budget?
Not necessarily—many sub-$100 microwaves deliver excellent value, especially if you prioritize core features over brand prestige. The Toshiba EM131A5C-BS, for example, rivals pricier models with its sensor cooking and mute function. However, if you need higher wattage or a larger capacity, you may need to stretch your budget slightly, but for most households, these budget picks perform admirably.
Can I repair an old microwave instead of buying a new one?
Yes, often you can—replacing a waveguide cover or grease filter is simple and cheap. The 5-pack of universal mica sheets and the Fetechmate filters we reviewed are perfect for DIY fixes. Just ensure you unplug the unit and follow safety guidelines, as microwaves store high voltage even when off. This approach can save you $50–$100 and keep your appliance running.
