Over-the-range microwave prices typically run $180-$900 for the appliance, with installation bringing a standard replacement to about $300-$1,300. Final quotes depend on capacity, venting, electrical work, removal, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Microwave only | $180 | $400 | $900+ | Most models are 30 inches wide |
| Basic replacement installation | $120 | $250 | $500 | Existing outlet and vent are usable |
| Appliance plus installation | $300 | $650 | $1,400+ | Higher with electrical or cabinet changes |
| Removal and disposal | $25 | $60 | $150 | May be included in installation |
What a 30-inch over-the-range microwave costs installed
A typical 1.6- to 2.2-cubic-foot microwave costs $250-$600, and a straightforward replacement usually adds $150-$350 for labor and basic supplies. That puts many complete jobs at $400-$950 before sales tax. Entry-level models may cost less, while premium finishes, convection cooking, or sensor features raise the equipment price.
Budget about $650 for a standard midrange unit and uncomplicated installation. The estimate assumes a 30-inch cabinet opening, an existing compatible electrical outlet, and no changes to the exhaust route. Assumptions: standard U.S. installation, typical access, and no cabinet repairs.
Where appliance, labor, and venting charges appear
Quotes can bundle parts and labor or list each separately. The ranges below represent common residential pricing; unusually difficult access or custom work can exceed them.
| Quote item | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Microwave | $180 | $400 | $900+ | Capacity, finish, and cooking features |
| Installation labor | $120 | $250 | $500 | Fit, access, and installation complexity |
| Mounting hardware or duct adapter | $15 | $50 | $130 | Whether the existing parts fit |
| Vent adjustment | $0 | $100 | $400 | New duct route or transition work |
| Removal and disposal | $25 | $60 | $150 | Haul-away distance and provider policy |
Check whether the quote includes mounting hardware, haul-away, and vent connection. These items can be omitted from a low advertised installation rate and added at checkout.
How cabinet width and exhaust route change the price
Most over-the-range models are designed for a 30-inch opening, but the cabinet, wall, and mounting bracket still need to match the appliance. A narrow opening or uneven cabinet may require carpentry, often adding $100-$400. A 1.6-cubic-foot unit can suit lighter use; a larger 2.0- to 2.2-cubic-foot model may cost $50-$250 more, depending on features.
Venting has a major effect on labor. Recirculating models filter air back into the kitchen, while externally vented installations need a compatible duct path. If a new duct run is needed, a short accessible route may add $100-$300; longer routes, roof exits, or difficult attic access can push the added work to $300-$800 or more.
Confirm the vent direction and duct size before ordering. Reusing a compatible opening is generally less expensive than cutting a new wall or roof exit.
How long does replacement labor usually take?
A two-person crew commonly needs 1-2 hours to remove an old unit and mount a replacement when the bracket, outlet, and vent are ready. Installation labor often works out to roughly $75-$150 per technician-hour, although contractors may charge a flat minimum rather than bill hourly.
New electrical work, cabinet repairs, or duct changes can extend the visit to 3-6 hours or require a separate trade. Ask whether the labor price covers testing the fan, lights, controls, and exhaust connection after installation.
Easy access and a compatible replacement keep labor near the lower end. Stairs, tight kitchens, or an unusually heavy unit can increase the time or crew charge.
What removal, electrical, and delivery can add
Haul-away may cost $25-$150, while delivery commonly adds $30-$100 when it is not included with the appliance purchase. Some retailers offer removal only when they deliver and install the new unit. Confirm who disconnects and carries away the old microwave, especially if it is mounted above a range.
A nearby grounded outlet is usually needed inside the cabinet above the microwave. If no suitable outlet exists, an electrician may charge about $150-$400 for accessible new wiring; complex routing or panel work can cost more. Permit requirements vary by locality and the scope of electrical work, so the installer should confirm local rules.
Get separate prices for delivery, removal, and electrical changes before scheduling. A low installation quote may not include any of these services.
Which microwave features justify a higher appliance price?
Basic units commonly fall around $180-$350, while midrange models with sensor cooking or stronger ventilation often cost $350-$650. Convection, premium finishes, and advanced controls can raise the price to $650-$1,000 or more. Compare usable capacity, fan performance, warranty terms, and control layout rather than paying extra for features that will rarely be used.
Higher fan ratings can help move more air, but the installed performance also depends on the duct and whether the unit vents outdoors. A recirculating setup may have fewer installation expenses, though it relies on replaceable filters and does not exhaust air outside.
Choose features based on cooking habits and the existing vent setup. A costly model cannot compensate for a restricted or incompatible duct route.
When repair costs less than replacing the microwave
Common repairs such as a door switch or fuse may cost $100-$250 including service, while control-board or magnetron repairs can reach $200-$500. Diagnostic fees often run $75-$150 and may be credited toward the repair. For an older unit, compare the complete repair quote with the price of a replacement and installation.
Replacement is often more practical when a repair approaches half the price of a comparable new appliance, particularly if the unit is out of warranty or has multiple faults. For a newer microwave with a simple, confirmed problem, repair may avoid installation and disposal charges.
Ask for the diagnostic fee and parts estimate before authorizing work. A verbal symptom-based estimate may change after inspection.
How to lower the installed price without cutting essentials
Measure the opening and check the model’s required clearances before buying. Matching the existing width, vent direction, and duct connection can prevent carpentry or duct changes. Compare at least three written quotes that identify appliance cost, labor, delivery, disposal, and any electrical work.
Bundling delivery and installation may save money, but compare the bundle total with separate prices and verify what haul-away includes. Avoid paying for rush scheduling if the old unit is safe to leave in place, and skip optional upgrades that do not solve a real cooking or ventilation need.
The largest controllable savings usually come from reusing a compatible opening, outlet, and vent route. Keep the model number and installation requirements with the quote so each installer prices the same scope.
