The familiar “50% rule” is useful, but it is not a law. If a repair approaches half the price of a comparable new appliance, replacement deserves serious consideration. The better decision also accounts for age, the failed component, remaining warranty coverage, energy use, installation cost and whether the appliance has a history of repeat failures.
Last reviewed: August 27, 2026. Appliance News treats the percentages below as decision aids, not industry standards or guarantees.
Use Three Tests: Cost, Age and Failure Type
- Cost: divide the all-in repair quote by the price of a comparable replacement, including delivery and installation. A ratio near or above 50% is a strong reason to compare replacement options.
- Age: compare the appliance with a realistic lifespan benchmark. The long-running NAHB planning figures are about 9 years for dishwashers, 10 for washers, 13 for refrigerators and dryers, 13 for electric ranges and 15 for gas ranges.
- Failure type: a belt, igniter, latch, valve or heating element can be a contained repair. A compressor, sealed refrigeration system, washer tub/bearing assembly or expensive electronic control can change the economics quickly.

Worked Example: A 9-Year-Old Dishwasher
Suppose a nine-year-old dishwasher needs a $300 repair and a comparable replacement costs $700 before installation. The repair is about 43% of the replacement price, but the dishwasher has also reached the NAHB benchmark age of nine years. If the failed part is a pump or main control and the machine has had previous repairs, replacement becomes easier to justify. If the quote is $150 for a door latch and the machine otherwise performs well, repair can still make sense.
Repair-or-Replace Signals by Appliance
| Appliance | Often repair-friendly | Get a replacement quote too |
|---|---|---|
| Refrigerator | Door gasket, inlet valve, many fan and ice-maker repairs | Major sealed-system or compressor work on an older unit; repeated cooling failures |
| Washer | Drain pump, inlet valve, latch, some suspension and drive repairs | Tub/bearing or transmission-level work on an older machine; repeated leaks |
| Dryer | Thermal fuse, belt, rollers, igniter or heating element | Major motor/control work when the machine is already near end-of-life |
| Dishwasher | Latch, valve, hose, some drain-pump repairs | Major circulation pump/control combinations on an older unit |
| Range/oven | Igniter, bake/broil element, many switches and sensors | Multiple electronic controls, structural damage or unavailable parts |
Check the Real Repair and Replacement Prices
Current national cost guides vary substantially because jobs, brands and local labor rates differ. HomeAdvisor’s June 2026 general appliance guide puts typical appliance repairs at $108–$251, while its appliance-specific guides span much wider ranges. Angi’s 2026 guides put an average washer repair around $220 and a typical dishwasher repair around $225. Use these only as national reference points; a written local diagnosis is more valuable than a national average.

Energy Use Can Change the Math
Refrigerators are the clearest example. ENERGY STAR says a refrigerator more than 15 years old can cost about $95 more per year to operate than a new ENERGY STAR-certified model. That does not make every old refrigerator an automatic replacement, but it means the repair decision should include future operating cost, not just today’s invoice.
Check the Warranty Before Paying
A machine can be outside its full warranty but still have component coverage. Some refrigerators, for example, carry longer sealed-system or compressor coverage than the one-year whole-appliance warranty. Confirm the exact model’s terms before authorizing a major repair. See the Appliance Warranty Guide.
Quick Decision Checklist
- Get the diagnosis and all-in repair price in writing.
- Price a genuinely comparable replacement, including delivery, installation and haul-away.
- Check the appliance age against its expected-life range.
- Ask whether the quote fixes one contained failure or a larger system problem.
- Check manufacturer, retailer, credit-card and service-plan coverage.
- Consider previous repairs and current parts availability.
- For refrigerators, compare energy use if the unit is old.
- For gas, refrigerant and high-voltage work, factor professional safety requirements into the decision.
