The costly microwave mistake usually happens before anyone compares models: assuming the price on the box is the price of the job. For a countertop microwave it is. A well-reviewed one costs $100 to $170 and plugs in, and that is the end of it. Over the range, the unit itself runs about $150 to $600, but installation adds $100 to $300 for a straight swap and roughly $1,000 to $3,000 more when the wall needs a new circuit and a vent.
So the useful question is not which microwave to buy. It is which of four kitchens you are standing in, because each one produces a very different bill. We priced all four with figures researched in November 2026, using retailer listings, review-site pricing and national cost data from HomeGuide, HomeAdvisor, Angi and Thumbtack.
Four kitchens, four very different totals
| Your kitchen | The microwave | Labor and extras | Likely total |
|---|---|---|---|
| 1. Countertop, any outlet | $100 to $170 | None | $100 to $170 |
| 2. Over-the-range, replacing the same size | $150 to $600 | $100 to $300 install, $20 to $50 haul-away | $270 to $950 |
| 3. Over-the-range where none hung before | $150 to $600 | Install, plus a $570 to $2,000 circuit and up to $600 of ductwork | $820 to $3,500 |
| 4. Drawer or built-in during a remodel | $700 to $2,250 | $220 to $580 install, $400 to $500 cabinet work, circuit if needed | $1,320 to $4,330 |
Kitchen one: a renter who just needs to heat leftovers
This is the cheap kitchen, and it should stay cheap. Reviewers keep landing on the same handful of models. CNN Underscored’s best overall pick, the Toshiba EM131A5C-BS, was listed at $130 on Amazon (down from $150), and Tom’s Guide also named it best overall, at $149.99. The Black+Decker EM925AB9 is the usual budget pick at $100 to $107, and CNN’s compact pick, GE’s smart countertop model, was $170 at Best Buy.
Spending more buys features rather than better reheating. The IKEA GÅTEBO combination microwave, which also bakes and grills, costs $199 and was Tom’s Guide’s combi pick. Breville’s Smooth Wave sat at $400 at Best Buy when CNN tested it. HomeGuide’s countertop range tops out at $500, and above about $200 you are paying for convection, a sensor menu or a finish that matches your toaster.
Two cheap checks before you buy: measure the counter depth with the door open, and look at the turntable size if you reheat dinner plates. Those, not wattage claims, are what owners complain about later.
Kitchen two: a dead over-the-range unit and a same-size replacement
Most over-the-range microwaves are 30 inches wide and hang from a wall plate with two bolts through the cabinet above. When the old one quits, the new one usually goes in the same hole, using the existing outlet in the cabinet and the existing vent path. That makes this the most predictable installed job.
Unit prices swing hard with sales. A Whirlpool 30-inch, 1.7-cubic-foot over-the-range model listed at $399 sold for $229 at Home Depot over Memorial Day 2026, and Slickdeals’ price history shows the same store selling it for $120 in November 2025. Patience on this purchase is worth more than brand choice. HomeGuide puts the over-the-range range at $150 to $600 before installation.
Labor is where the national sources roughly agree:
- HomeGuide: $100 to $300 to install an over-the-range microwave, unit not included, with handymen and electricians billing $50 to $100 an hour.
- Thumbtack (April 2026): a national average of $122 to $255, from a low of $74 to a high of $487 when wiring or cabinet work is involved.
- HomeAdvisor: $20 to $50 to haul the old unit away, though many installers fold it into the job.
Add it up for the Whirlpool at its sale price and a mid-range installer, and a typical replacement lands around $370 to $530. A simple swap generally needs no permit, according to Thumbtack. The new unit ships with its own mounting plate, and the bolt holes in the cabinet rarely line up perfectly with the old ones, which is why the job takes an installer an hour or two rather than 20 minutes.
Kitchen three: moving the microwave off the counter and over the stove
This is the kitchen where budgets break. You have a range hood, or bare wall, above the stove and want to reclaim counter space. The microwave is the same $150 to $600 item as in kitchen two. What changes is everything behind it.
The circuit
HomeAdvisor notes that most over-the-range units call for their own 120-volt, 20-amp circuit and prices that at $800 to $2,000. Angi’s 2026 data is a little lower: about $700 on average for a dedicated circuit, with a normal range of $570 to $1,000 and inspection fees of $100 to $400 in some places. If your panel has no room, Angi adds $1,200 to $2,000 for an upgrade. Check your installation manual before assuming you can share the old hood’s wiring; the manufacturer’s electrical requirements are what the inspector will read.
The vent
Over-the-range microwaves can recirculate air through a charcoal filter or exhaust it outside. If you are replacing a ducted hood, the duct is usually reusable with a transition piece. With no duct at all, HomeAdvisor budgets $150 to $600 for new ductwork, or you can skip it and run the unit in recirculating mode. Thumbtack notes that new circuits and new ductwork are the two things that can turn a no-permit job into a permitted one.
Put those together and the same $229 microwave can cost $820 installed in a kitchen where a circuit is easy to run, or $3,500 where the electrician has to fish wire across a finished ceiling and a duct has to go through an exterior wall. Get the electrician’s quote first. If it comes back near the top of that range, a good countertop model and a better range hood may be the smarter spend.
Kitchen four: a microwave drawer in a remodel
Drawer microwaves slide out from base cabinets, keep the counter clear and put hot food at waist height. They are also where the price list jumps. HomeGuide prices drawers at $700 to $1,800 in its built-in table. At the top end, AJ Madison listed the Bosch 800 Series 24-inch drawer (HMD8454UC) at $2,149 against a $2,399 MSRP in November 2026, and the 30-inch HMD8054UC at $2,249. P.C. Richard showed the 24-inch model at $2,149.98.
Installation is real cabinetry work. HomeGuide puts built-in microwave installation at $220 to $580, and HomeAdvisor adds $400 to $500 for modifying a cabinet to take one. If the electrician is already on site for a remodel, the circuit tends to disappear into a larger electrical line item; if not, budget the same $570 to $1,000 as kitchen three. That gives a range of about $1,320 for a modest drawer in a cabinet that is already open to $4,330 for a premium unit with its own new circuit.
Bosch was running mail-in rebates through December 2026 for buyers of multiple Bosch kitchen appliances. If a drawer is part of a full appliance package, ask the dealer which promotions stack before you order piece by piece.

Combination microwave and wall ovens sit above all of this, at $2,350 to $7,000 or more in HomeGuide’s data. Those belong in the kitchen remodel budget, not the microwave budget. Our kitchen remodel cost guide covers how appliances fit into the full project.
When the old one dies: fix it or buy again
HomeGuide puts typical microwave repairs at $100 to $300 and expected life at seven to 10 years. Its rule of thumb is to repair only a high-end unit that is under five years old and needs a minor fix. Run that against the four kitchens and the answer gets simple. In kitchen one, a $300 repair on a $130 microwave is never the right call. In kitchen two, a repair makes sense only if it costs less than the new unit plus about $250 of installation. In kitchen four, fixing a $2,000 drawer is usually worth a service visit.
Nothing on the regulatory side looks likely to move microwave prices for 2027. The Department of Energy proposed in May 2025 to rescind its energy conservation standards for microwave ovens; we found no final rule that changes what is on store shelves, and no manufacturer has announced 2027 price changes tied to it. Sale cycles matter far more. The Whirlpool model above swung between $120 and $399 within a year.
Smaller questions about microwave prices
How much does microwave installation cost if the outlet and vent are already there?
Usually $100 to $300 for an over-the-range unit, according to HomeGuide, and Thumbtack reports a national average of $122 to $255. Countertop models need no installation. Built-in models cost more to install, about $220 to $580.
Why is a combination microwave oven price so much higher?
Combination units add convection, grilling or full oven functions. Countertop combis such as the IKEA GÅTEBO cost about $199, and the Breville Smooth Wave was $400 at Best Buy. Built-in microwave and wall oven combinations run $2,350 to $7,000 or more in HomeGuide data.
Do I need a permit to install a microwave?
A like-for-like swap generally does not need one. Adding a new electrical circuit or running new ductwork may require a permit, so check with your local building department before that kind of job.
Can an over-the-range microwave replace my range hood?
It can handle venting, either by recirculating air through a charcoal filter or by exhausting outside through ductwork. If you cook a lot of high-heat or greasy food, compare the microwave’s fan rating with your current hood before giving the hood up.
How long should a new microwave last?
HomeGuide puts the average at seven to 10 years, depending on use and care. A cheaper model may not last as long, so factor the replacement cycle into the price you are willing to pay.

Before you ask anyone for a quote
Installers price what they can see, so give them the facts that move the number:
- A photo of the inside of the cabinet above the stove, showing whether an outlet is already there.
- Where the current hood or microwave vents: through the cabinet to the roof, out the back wall, or nowhere.
- A photo of your electrical panel with the door open, so an electrician can tell you at once whether a new circuit is a $600 job or a panel upgrade.
If all three come back clean, you are in kitchen two and the bill stays under $1,000. If the panel photo draws a long pause, rethink where the microwave goes before you buy it.
Pricing method: prices were researched in November 2026 for 2027 planning and may change. Unit prices come from AJ Madison, P.C. Richard, Home Depot (via Slickdeals price history), CNN Underscored and Tom’s Guide listings; installation, circuit and ductwork ranges come from HomeGuide, HomeAdvisor, Angi and Thumbtack.
