Quick Answer: If a repair costs less than 50% of what the appliance would cost to replace today — and the unit is still in the first half of its expected lifespan — repairing is almost always the better financial choice. When repair costs climb above that threshold or the appliance is aging out, replacement typically wins.
The 50% Rule: Your Starting Point
The most widely cited guideline in the appliance industry is the 50% rule: if the cost to repair an appliance exceeds 50% of its current replacement cost, you're generally better off replacing it.
Here's how to apply it in three steps:
- Get a written repair estimate from a qualified technician.
- Research what a comparable new model costs today — not what you paid years ago.
- Divide the repair cost by the replacement cost. If the result is 0.5 or higher, lean toward replacement.
For example, if a new dishwasher runs around $700 and the repair quote is $280, that's roughly 40% — typically worth fixing. If the quote climbs to $400 or more, replacement starts to make financial sense. The 50% rule is a starting point, not an absolute law — age, reliability history, and energy efficiency all play a role, which is why we've broken things down appliance by appliance below.
Appliance Lifespan Guide
Knowing how old your appliance is relative to its expected lifespan matters just as much as the repair cost. A repair that buys you five more years on a young refrigerator is a great deal. The same repair on a 20-year-old unit that has already outlived its peers may just delay an inevitable replacement.
| Appliance | Typical Lifespan | Repair-Friendly Zone | Consider Replacing If... |
|---|---|---|---|
| Refrigerator | 13–17 years | Years 1–8 | Over 10 years + major component failure |
| Washing Machine | 10–14 years | Years 1–7 | Over 8 years + drum or motor issues |
| Dryer | 10–13 years | Years 1–6 | Over 8 years + heating element failure |
| Dishwasher | 9–12 years | Years 1–6 | Over 7 years + pump or control board failure |
| Gas/Electric Range | 13–15 years | Years 1–8 | Over 10 years + multiple failing burners |
| Microwave | 7–10 years | Years 1–5 | Over 6 years + magnetron failure |
Breaking It Down by Appliance
Refrigerator
Refrigerators are usually worth repairing because they're expensive to replace — typically $800 to $2,500 or more for a quality model. Common, fixable problems include worn door gaskets, a faulty ice maker or water dispenser, dirty condenser coils, and thermostat or sensor issues.
Compressor failure is the big exception. A compressor replacement typically runs $400–$600 in parts and labor, which can approach or exceed the 50% threshold on older units. If your refrigerator is over 10 years old and the compressor is failing, replacement is usually the smarter call. Our refrigerator repair specialists can give you an honest diagnosis. See our appliance repair cost guide for typical price ranges by repair type.
Washer & Dryer
Washers and dryers have shorter lifespans than refrigerators, so age matters more here. A washing machine under seven years old is almost always worth repairing unless the drum, motor, or control board has failed — those repairs can run $300–$500+, which may push past the 50% threshold on a mid-range unit.
Dryers are often cheaper to repair than washers because they have fewer complex components. A heating element replacement, for instance, typically runs $100–$200 in parts and labor and can add several years of life to an otherwise healthy machine.
Common signs it's time to replace rather than repair:
- Washer leaks from the drum seal and is over eight years old
- Dryer takes two or more cycles to fully dry a load (even after vent cleaning)
- Control board failure on a unit more than halfway through its expected lifespan

Dishwasher
Dishwashers have one of the shorter lifespans among major appliances — typically nine to twelve years. Minor repairs like a spray arm, door latch, or drain hose are almost always cost-effective. More expensive repairs — pump motor, control board, or main pump assembly — should be weighed carefully if the unit is already six to seven years old.
One often-overlooked factor is energy efficiency. Dishwashers made before roughly 2013 use significantly more water per cycle than current Energy Star models. If your unit is aging and repair costs are moderate, it may still make sense to replace it on efficiency grounds alone. Our dishwasher repair team can quickly assess whether a fix is worthwhile.
Oven & Range
Ovens and ranges tend to be durable — thirteen to fifteen years is realistic for a well-maintained unit. Most common issues (a faulty igniter, a burned-out burner element, a broken oven temperature sensor) are relatively inexpensive to address, usually in the $100–$250 range in parts and labor.
Where costs escalate is with control board replacement or a cracked glass cooktop. Those repairs can run $300–$600+, which may approach the 50% threshold on a budget-tier range. On a high-end or professional-style range, the same repair is often still justified given the higher replacement cost. Visit our oven repair page for more detail on what's typically fixable.
Other Factors That Tip the Scale
Beyond the 50% rule and lifespan, keep these factors in mind before making a final call:
- Repair history: If you have already invested in multiple repairs over the past 12–18 months, the appliance may be entering a failure cycle. Future repair costs will likely compound.
- Energy efficiency: Older appliances — especially refrigerators and washing machines — can cost $50–$150 more per year to operate than current Energy Star-certified models. Factor ongoing operating cost into the long-term math.
- Parts availability: For discontinued or rare models, parts may be hard to source or backordered for weeks. Ask your technician about availability before committing to a repair timeline.
- Utility rebates: Many utility companies and some state programs offer rebates for replacing old, inefficient appliances. Check your local utility's website — this can meaningfully change the math in favor of replacement.
- Your timeline: If you plan to sell your home within a year, a modest repair that keeps the appliance functional may be smarter than a full replacement that buyers are unlikely to pay back dollar-for-dollar.
Not Sure? Get a Diagnosis Before You Decide
The single best thing you can do before making a repair-or-replace decision is get an accurate estimate from a qualified technician. Many homeowners assume a problem is worse — and more expensive — than it actually is, and end up replacing an appliance that could have been fixed for under $150.
ApplianceCos provides honest, upfront estimates with no pressure to commit. If we believe replacement makes more financial sense for your situation, we'll tell you plainly. Call us at (832) 268-7733 or book a service visit online. You can also run the numbers yourself with our repair-or-replace calculator before we arrive.
Conclusion
The repair-or-replace decision does not have to be stressful. Start with the 50% rule, factor in the appliance's age relative to its expected lifespan, and weigh energy efficiency and repair history before committing. In most cases, an appliance that is less than halfway through its life and facing a modest repair bill is worth fixing — and a qualified technician can confirm that quickly.
When you are ready for a professional opinion, ApplianceCos is here to help. Our technicians diagnose the problem accurately, provide a clear estimate, and help you make the smartest choice for your household and budget.
