Repair or Replace? Appliance Decision Calculator (2026)
Quick Answer
Use the 50% rule — replace if the repair costs more than half a comparable new unit — but adjust it for two things generic advice ignores: your appliance’s age and where you live.
- Always repair: a cheap, well-understood part (dryer fuse, washer drain pump, dishwasher latch) on a machine under two-thirds of its lifespan
- Always replace: a sealed-system fridge compressor ($700–$1,250) on a mid-range unit over 8 years old
- Regional rule: in hot-humid or hard-water regions, add 1–3 years to the calendar age before deciding
- Use the calculator below for a defensible verdict with a confidence level
Your appliance just broke, a technician quoted a repair price, and now you have to make a decision worth hundreds or thousands of dollars in the next five minutes. Repair it and risk throwing good money after a dying machine — or replace it and risk scrapping an appliance that had years left. This page gives you a defensible answer instead of a guess, built on the same rule professional technicians use, adjusted for how old your specific appliance is and where you live.

The 50% Rule, and Why It Is Only Half the Answer
The industry standard for this decision is the 50% rule: if a repair costs more than half the price of a comparable new unit, replace it; if less, repair it. It is a good starting point and every honest technician uses some version of it. A $200 repair on a dishwasher that costs $600 new is 33% of replacement — repair. A $400 repair on that same dishwasher is 67% — replace.
But the 50% rule on its own has a hole in it: it ignores age. A $250 repair on a three-year-old washer and the identical $250 repair on a twelve-year-old washer are not the same decision, even though the 50% math is identical, because the three-year-old machine has a decade of life left and the twelve-year-old is already past its expected lifespan. The real decision combines three variables: repair cost, replacement cost, and remaining useful life. The calculator above weighs all three.
The Numbers Behind the Calculator
Every threshold in the calculator is built on current 2026 cost and lifespan data, not estimates. Here are the replacement-cost and lifespan figures it uses.
| Appliance | Typical repair | New unit cost | Avg lifespan |
|---|---|---|---|
| Refrigerator | $125–$500 ($700–$1,250 compressor) | $600–$2,300 | 9–13 yrs |
| Washing machine | $100–$400 | $700–$1,300 | 10–12 yrs |
| Dryer | $100–$300 | $800–$1,200 | 13 yrs |
| Dishwasher | $100–$400 | $400–$1,000 | 9 yrs |
| Oven / range | $150–$350 | $600–$1,300 | 13–15 yrs |
| Microwave | $100–$250 | $200–$600 | 9 yrs |
| Freezer | $100–$400 | $350–$1,100 | 10–20 yrs |
| Garbage disposal | $100–$250 | $200–$550 | 12 yrs |
How the Verdict Is Calculated
The calculator applies three tests in order. If a repair fails any one of them, the verdict tilts toward replace.
The cost test
The classic 50% rule: repair cost divided by replacement cost. Under 50% passes, over 50% fails.
The age test
Compares the appliance’s current age to its expected lifespan. An appliance in the first half of its rated life passes easily; one in the final third fails, because you would be paying to repair a machine that is statistically near the end regardless.
The combined test
This is where real judgment lives. A cheap repair on an old machine can still be worth it if it buys a year or two; an expensive repair on a newer machine can still be wrong if that model has a known failure pattern. The calculator surfaces this as a confidence level, not just a yes or no.
The Regional Adjustment Nobody Else Makes
Generic repair-or-replace advice assumes a national-average appliance in a national-average home. Yours is neither, and the gap changes the answer.
If you live in a hot, humid, coastal market — Tampa, Naples, Boca Raton, Aventura — your appliances are aging faster than the national average by an estimated one to three years because of heat, humidity, and storm-season power surges. That means the effective age should be treated as older than the calendar age, which pushes borderline cases toward replace. If you do replace, surge protection on the new unit is a genuine reliability investment, not an upsell.
If you live in a hard-water market — Chicago, Columbus, Philadelphia, much of Houston — scale buildup shortens the life of every water-using appliance, cutting dishwasher and water-heater lifespans by 30 to 50%. A dishwasher the calculator would normally call “repair” at year six may be a “replace” in untreated hard water, because the scale damage you can see usually signals more you cannot. (See how hard water wrecks a dishwasher.)
When to Always Repair, and When to Always Replace
✅ Always repair
A cheap, well-understood part — a dryer thermal fuse, a washer drain pump, a dishwasher door latch — on a machine less than two-thirds through its lifespan. These repairs routinely cost under $200 and buy years.
🔁 Always replace
A sealed-system fridge compressor on a mid-range unit over 8 years old; total repairs in the past year already near half of replacement; anything beyond trivial once the unit is past its rated lifespan; or a known problem model (e.g. certain Samsung french-door icemakers).
