A good microwave under $100 is not a luxury appliance. It is a practical kitchen tool that should reheat leftovers, soften butter, warm coffee, steam vegetables, and handle weekday meals without stealing too much counter space. In 2026, the best values under $100 are almost always countertop microwaves in the 0.7 to 0.9 cubic foot range, usually between 700 and 900 watts. A few 1.1 cubic foot models occasionally drop near $90 to $100 during sales, but those are the exception, not the rule.
From a builder’s point of view, the smartest budget microwave is the one that fits the kitchen safely. On our job sites, the microwave decision often affects outlet placement, pantry design, landing space, cabinet depth, and whether a family ends up with a cluttered prep zone. A $70 microwave can be a smart buy. A $70 microwave plugged into an extension cord, wedged into a closed cabinet, or sharing a crowded outlet with an air fryer and coffee maker is not.
If you want the short answer: choose a 0.9 cubic foot, 900-watt countertop microwave if you can find one under $100 and it fits your plate, counter depth, and outlet location. Choose a 0.7 cubic foot, 700-watt model if you need the smallest footprint for a dorm, office, wet bar, rental unit, secondary kitchen, or light reheating. Spend your real construction dollars on safe outlet placement, proper circuit capacity, and a microwave location that people can use without fighting the kitchen layout.
What You Can Realistically Get Under $100 in 2026
The under-$100 microwave category is narrow but useful. Most models are compact countertop units with a turntable, digital controls, basic presets, defrost settings, a kitchen timer, and a child lock. Finishes are usually black, white, stainless-look, or black stainless-look. You should not expect true built-in capability, drawer-style operation, convection cooking, sensor cooking on every model, or over-the-range ventilation at this price.

Typical 2026 sub-$100 pricing looks like this: 0.7 cubic foot microwaves at 700 watts commonly land around $50 to $80. Models in the 0.9 cubic foot and 900-watt range often fall between $60 and $100, depending on the retailer and sale timing. Occasionally, a 1.1 cubic foot microwave will appear near $90 to $100, but inventory changes fast and dimensions need to be checked carefully.
Retailer listings in this category show real availability. Target has listed Black+Decker 0.7 cubic foot models around $49.99 on sale. Walmart has listed Chefman and Frigidaire 0.7 cubic foot models around $69.99 to $79.99. Home Depot has listed compact models such as a Vissani 0.7 cubic foot microwave around $59.98. Best Buy, Walmart, Target, and Home Depot all tend to rotate promotions, so the best model under $100 this month may not be the best value next month.
The important point is that under $100 buys a simple countertop appliance, not a remodeling solution. If your kitchen already has a grounded 120-volt receptacle in the right place, your all-in cost may be the appliance price alone. If you need a new outlet, a dedicated circuit, cabinet modification, or an over-the-range replacement, the installed cost can exceed the microwave price several times over.
Best Microwave Types Under $100
Best Overall Budget Choice: 0.9 Cubic Foot, 900 Watts
For most households, a 0.9 cubic foot microwave at 900 watts is the sweet spot. It is still compact, but it usually feels less underpowered than a 700-watt unit. It can handle more dinner plates, meal-prep containers, soup bowls, and frozen entrees. Reheat times are shorter, and the interior feels less cramped for everyday use.

The turntable diameter is often more useful than the cubic-foot number. If your standard dinner plate is 10.5 to 11 inches across, confirm that the turntable and interior width can handle it before buying.
Best Small-Space Choice: 0.7 Cubic Foot, 700 Watts
A 0.7 cubic foot, 700-watt microwave is the common entry-level budget model. It is a good fit for apartments, offices, basement bars, guest suites, dorm-style setups, small rentals, and occasional reheating. These units often cost $50 to $80 and can fit on tighter counters where a deeper appliance would interfere with the work zone.
The tradeoff is performance. A 700-watt microwave will heat more slowly than a 1,000- or 1,200-watt model. If a frozen meal says 4 minutes based on a higher-wattage oven, a 700-watt unit may need 5 to 6 minutes, plus stirring or standing time. For one person reheating leftovers, that may be fine. For a family trying to move dinner along, it can feel slow.
Best Sale Find: 1.1 Cubic Foot Near $100
A 1.1 cubic foot microwave under $100 is worth considering when it appears, but do not buy it by capacity alone. Larger budget units can be deeper than expected and may overwhelm a shallow counter, corner, pantry shelf, or appliance garage. A model that sticks out 17 inches on a 24-inch-deep counter may leave too little usable landing space in front.
Before buying a larger sale model, measure width, height, depth, door swing, cord location, and required clearances. Also check the return policy. Budget appliance deals are only helpful if the unit actually works in your kitchen.

Quick Cost Comparison: Cheap Microwave vs Installed Alternatives
The purchase price is only one part of the decision. A countertop microwave can be nearly plug-and-play. An over-the-range or built-in microwave becomes a small construction project, especially if the cabinets, backsplash, ducting, or electrical layout are not ready.
| Option | Typical 2026 Cost | Best For | Construction Notes |
|---|---|---|---|
| Compact countertop, 0.7 cu. ft./700W | $50-$80 | Dorms, offices, wet bars, rentals, light reheating | Needs stable counter space, ventilation clearance, and nearby grounded 120V outlet |
| Larger budget countertop, 0.9 cu. ft./900W | $60-$100 | Most budget kitchens and small households | Check plate fit, counter depth, door swing, and shared circuit load |
| Basic installed replacement | $120-$250 labor, often plus appliance | Replacing a similar existing microwave | Costs vary by mounting, outlet condition, disposal, and fit |
| Over-the-range or built-in work | About $400-$600 for common installation work; built-in projects can run much higher | Freeing counter space, integrated remodels, range-area layouts | May involve cabinets, venting, tile, electrical work, permits, and inspection |
HomeAdvisor reports professional microwave installation around $120 to $222, with an average near $155. Thumbtack reports a national average range of roughly $122 to $255. Angi places standard professional microwave installation around $120 to $250, while over-the-range or built-in work can run about $400 to $600. ConsumerAffairs reports that built-in microwave costs can range from about $275 to $2,800 on average, depending on the appliance and project conditions.
That is why a countertop microwave under $100 can make excellent sense during a budget kitchen refresh. If the kitchen layout already works, you may be better off buying a simple countertop unit and using the saved money for outlet corrections, lighting, cabinet hardware, backsplash repair, or better storage.
How to Choose the Right Microwave Under $100
Start With the Plate, Not the Price Tag
Measure your largest everyday plate, bowl, mug, baby-bottle sterilizer, or meal-prep container. Then compare that measurement with the microwave’s interior dimensions and turntable diameter. Cubic feet can be misleading because a tall but narrow cavity may still fail to fit the container you use every day.
For a standard 10.5- to 11-inch dinner plate, many 0.7 cubic foot units are tight. Some fit the plate, but the corners may be close to the walls or the plate may not rotate freely. A 0.9 cubic foot unit is more likely to feel comfortable for daily use.
Match Wattage to How You Actually Cook
Budget microwaves usually range from 700 to 900 watts. A 700-watt model is adequate for reheating coffee, soup, leftovers, and small frozen meals. A 900-watt model is better for repeated daily use, larger portions, and households where the microwave does more than occasional warming.
Higher wattage is not just about speed. It affects evenness and predictability. Budget units usually heat less evenly than 1,000- to 1,200-watt models, so real-world performance matters more than preset buttons. Stir food halfway through, rotate larger containers if needed, and allow standing time so heat can distribute.

1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteCheck Exterior Depth and Door Swing
Counter depth is one of the most common misses we see in kitchen planning. A microwave that technically fits on the counter may still make the counter hard to use. Measure the full exterior depth, including rear spacing and any handle or protruding door. Then confirm that the door can swing open without hitting a wall, tall pantry side panel, refrigerator handle, or corner trim.
On a standard 24-inch-deep counter, a compact unit often works well. On a shallow bar counter, pantry shelf, or appliance garage, even a small microwave can become awkward. Leave enough room in front to set down a hot bowl safely.

Where a Budget Microwave Should Go in a Kitchen Remodel
During remodel planning, we try to place the microwave near the refrigerator or pantry but outside the busiest sink-range prep path. That keeps reheating and snack traffic from colliding with the person cooking. In family kitchens, that detail matters every day.
A countertop microwave needs a flat, stable surface and the manufacturer-required side, rear, and top clearance. Do not assume a countertop microwave can go inside a closed cabinet. Most budget models are listed for countertop use only, and they rely on open airflow around the case. Blocking vents can shorten appliance life and create a safety hazard.

If counter space is tight, a pantry shelf or appliance garage can work only when the appliance instructions allow that placement and clearances are maintained. The shelf must support the appliance weight, resist heat and moisture, and provide room for the door, cord, and ventilation. A slide-out shelf may sound convenient, but it must be sturdy enough for the appliance and the force of opening and closing the door.
For aging-in-place and family kitchens, placement height matters as much as capacity. When possible, place the microwave so the bottom of the cooking cavity is roughly between waist and chest height for the primary users. Avoid high cabinets where someone has to lift hot soup or coffee down from above shoulder level. That is a spill and burn risk, not just an inconvenience.
Electrical and Safety Details Homeowners Should Not Ignore
A countertop microwave should plug into a nearby grounded 120-volt receptacle. Extension cords and power strips are common mistakes. They create trip hazards, add resistance, and can overload a setup that was never meant for a heating appliance. If the cord does not reach a proper outlet, that is a layout problem to fix, not a reason to stretch the cord across the counter.
Modern kitchen electrical rules commonly require GFCI protection for receptacles serving kitchen countertops, and many jurisdictions also require AFCI protection in dwelling-unit kitchen areas. Kitchens also typically require 20-amp small-appliance branch circuits. Local code adoption varies, and remodel scope can affect what must be updated, so electrical work should be confirmed with the local authority having jurisdiction or a licensed electrician.
Recommended Free Tools
Load matters. A microwave may share the kitchen with a coffee maker, toaster oven, air fryer, blender, refrigerator, and dishwasher. A small 700-watt microwave draws less than a larger unit, but the total circuit load can still become a nuisance or safety issue. If breakers trip when multiple appliances run, do not keep resetting them and hoping for the best. Have the circuit evaluated.
For remodels, spend money on the electrical plan before spending on premium microwave features. A well-located receptacle, correct circuit capacity, proper GFCI/AFCI protection, and clean counter layout will improve the kitchen more than a few extra preset buttons.
When to DIY vs When to Hire a Pro
DIY Is Usually Fine for a Countertop Microwave
Most under-$100 countertop microwaves are homeowner-friendly. The basic setup requires a tape measure, level, cleaning cloth, owner’s manual, stable counter space, and a grounded 120-volt kitchen receptacle. Unbox it, inspect for shipping damage, install the turntable correctly, wipe the interior, place it with the required clearances, and test it with a microwave-safe cup of water.

Plan 15 to 30 minutes for a simple setup. Keep the manual because clearance requirements, cabinet restrictions, and electrical warnings vary by manufacturer. Register the appliance if you want warranty support.
Hire a Pro When Wiring, Mounting, Cabinets, or Venting Are Involved
Bring in a qualified professional if you need to add or move an outlet, correct an ungrounded receptacle, add GFCI or AFCI protection, troubleshoot tripping breakers, install an over-the-range microwave, vent outdoors, modify cabinets, cut tile or backsplash, or replace a built-in unit with different dimensions.
Permits may be required when new electrical work is performed, when circuits are added, or when a remodel changes kitchen wiring. Requirements vary by city, county, and state. For a simple plug-in countertop microwave using an existing compliant receptacle, a permit is typically not part of the appliance setup. For new wiring, panel work, or built-in installation during a remodel, assume the work may need inspection until your local authority or electrician confirms otherwise.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common Mistakes That Make a Cheap Microwave Expensive
The first mistake is buying by price alone. A $50 microwave that is too small for your plates or too slow for your household will frustrate you every day. For a family kitchen, stepping from 0.7 cubic foot and 700 watts to 0.9 cubic foot and 900 watts is often worth the extra $20 to $40 if the model stays under budget.
The second mistake is ignoring the exterior footprint. Measure the appliance, not just the box label. Door swing, rear clearance, side vents, top clearance, cord location, and handle depth all affect whether the microwave works in the space.
The third mistake is treating a countertop model like a built-in. Most budget microwaves are not designed to be boxed tightly into cabinetry. Without proper airflow, heat builds up around the unit. That can damage the appliance and create a hazard.
The fourth mistake is sacrificing real ventilation over the range. A countertop microwave does not replace a range hood. If you remove a hood to save money and do not provide proper cooking ventilation, the kitchen may collect grease, steam, smoke, and odors. In many remodels, keeping or improving ventilation is more valuable than mounting a microwave above the range.
The fifth mistake is placing the microwave too high. Hot liquids and heavy bowls should not be lifted down from above shoulder height. This is especially important for children, older adults, and anyone with limited reach or grip strength.
Our Practical Buying Recommendation
For a primary kitchen, start your search with a 0.9 cubic foot, 900-watt countertop microwave under $100. Look for a turntable large enough for your everyday plate, simple controls, a child lock, clear display, one-touch add-30-seconds function, and a finish that does not make the kitchen look cheaper than the savings justify.

For a secondary space, rental, office, dorm, guest suite, or wet bar, a 0.7 cubic foot, 700-watt model is usually enough. It will be slower, but it costs less, takes up less room, and still handles basic reheating.
Before recommending a specific model, confirm current price, availability, dimensions, warranty, and return policy directly on retailer pages. Product roundups from testing sites are useful for model discovery, but the construction details decide whether the appliance belongs in your kitchen. A budget microwave should fit your plates, fit your counter, plug in safely, breathe properly, and stay out of the main work zone.
That is the real standard for the best microwave under $100. It is not the cheapest box on the shelf. It is the compact appliance that works with the kitchen you have, or the kitchen you are planning to build.

A 700-watt microwave is fine for light reheating, small frozen meals, offices, dorms, and secondary spaces. For family use or frequent cooking, 900 watts is usually more comfortable because it heats faster and handles larger portions better.
What size microwave fits a standard dinner plate?
Many standard dinner plates are about 10.5 to 11 inches wide. Check the microwave’s turntable diameter and interior width before buying. A 0.9 cubic foot model is more likely to fit everyday plates comfortably than a compact 0.7 cubic foot model.
Does a countertop microwave need a dedicated circuit?
Not always, but it does need a properly located grounded 120-volt receptacle and enough circuit capacity. Kitchen counter receptacles are commonly on 20-amp small-appliance circuits, and local code may require GFCI and AFCI protection.
Can I put a countertop microwave inside a cabinet or pantry shelf?
Only if the manufacturer allows that placement and all required ventilation clearances are maintained. Most under-$100 microwaves are designed for countertop use, not tight built-in cabinet installation.
