Repair or Replace? How to Decide in 5 Minutes (Without Regret)
Use the 50% rule: replace an appliance only when both are true — it's past 50% of its expected lifespan, and the repair quote is more than 50% of what a comparable new unit costs. One condition alone isn't enough. A $400 fix on a 3-year-old washer? Repair. The same $400 fix on a 9-year-old washer that costs $700 to replace? Replace.
This guide gives you the rule done right, a decision matrix for every major appliance, and the two modifiers most people miss: sealed-system quotes and energy costs.
The 50% Rule, Properly Explained
Quick answer: replace when appliance age > 50% of expected lifespan AND repair quote > 50% of replacement cost. If only one condition is met, repair usually still wins.
Most sites quote half the rule ("replace if the repair costs half of new"). That version wastes money in both directions:
- Cost alone misleads on young appliances. A $350 control board on a 2-year-old, $600 dishwasher technically fails the cost test — but the machine has ~7 good years left, so the repair buys you far more life per dollar than a new unit would.
- Age alone misleads on cheap fixes. A 12-year-old fridge with a $90 fan repair passes the age test for replacement — but $90 for another year or two of service is still a good trade.
Why the age half of the rule matters so much: appliances fail as systems, not as single parts. Once one major component wears out, its neighbors are usually close behind — and every new failure re-triggers a $70–$130 service call before a wrench even turns (HomeGuide labor data, as of August 2026). Paying $400 to fix a machine that's 80% through its life often just reserves your seat for the next $400.
Age × Cost Decision Matrix by Appliance
Quick answer: find your appliance's "half-life age" below. Past it, any quote above the "walk-away quote" column points to replacement.
Lifespans are from the NAHB Study of Life Expectancy of Home Components; repair ranges are 2025–2026 published national data (as of August 2026). Replacement costs are typical mid-range retail — luxury and built-in units shift the math upward.
| Appliance | Expected life (NAHB) | Half-life age (replace-zone starts) | Typical repair cost | Typical mid-range replacement | Walk-away quote (~50% of new) |
|---|---|---|---|---|---|
| Refrigerator | 13 yrs | 6.5 yrs | $150–$650 | $800–$2,000 | ~$400–$1,000 |
| Washing machine | 10 yrs | 5 yrs | $100–$400 | $600–$1,100 | ~$300–$550 |
| Dryer | 13 yrs (10–13 band) | 5–6.5 yrs | $100–$300 | $500–$1,000 | ~$250–$500 |
| Dishwasher | 9 yrs | 4.5 yrs | $160–$300 | $500–$1,000 | ~$250–$500 |
| Gas range | 15 yrs | 7.5 yrs | $130–$310 | $700–$1,500 | ~$350–$750 |
| Electric range | 13 yrs | 6.5 yrs | $130–$310 | $600–$1,300 | ~$300–$650 |
| Microwave | 9 yrs | 4.5 yrs | $100–$200 | $100–$400 (countertop) | Rarely worth a paid repair |
How to read it, using a real scenario: your 8-year-old washer needs a $350 drain pump job. Age check: 8 > 5 (past half-life — fail). Cost check: $350 vs. ~$800 replacement = 44% (pass). One fail, one pass → repair, but treat it as the last one. If anything else breaks, replace without a second thought.
One caveat on the lifespan column: AHAM data shows average appliance lifespans compressed between 2010 (11–16 years) and 2019 — modern, electronics-heavy units fail sooner than the machines your parents owned. If your appliance is a feature-loaded model from the last decade, lean toward the pessimistic end of each band.

The Sealed-System Tipping Point: $1,400–$2,800
Quick answer: a sealed-system repair (compressor, refrigerant loop, evaporator) on a standard refrigerator costs $1,400–$2,800 as of August 2026 — an automatic replace verdict for nearly every fridge under ~$2,500 new.
This is the single most expensive common appliance repair, and it's where homeowners lose the most money by saying yes too fast. Run the rule: a standard fridge replaces for $800–$2,000. Even the bottom of the sealed-system range ($1,400) clears 50% of the top of that replacement band. Both halves of the 50% rule fail almost automatically.
The exceptions, where sealed-system repair can still pencil out:
- Built-in and pro-grade refrigerators ($3,000–$10,000+ to replace) — here $1,400–$2,800 may be well under 50%.
- Units still under warranty. Compressors often carry longer manufacturer coverage than the rest of the fridge (LG's compressor saga made this famous), and a home warranty may cover the failure up to its cap — check before paying cash. See how a fridge failure gets diagnosed so you know a sealed-system verdict is real before accepting it.
Three More Modifiers Before You Decide
- Parts availability. If the model is discontinued and the part is scarce or salvage-only, a "repairable" appliance may not be practically repairable. If a part search comes up empty at the major OEM retailers, that's your answer.
- Warranty status. Under a manufacturer warranty or home warranty? File the claim first — never pay cash for a covered repair.
- Failure history. Second major failure in 12 months = replace, almost regardless of the quote. You're not fixing a machine anymore; you're subscribing to service calls.
FAQ
Replace an appliance when both conditions are true: it's more than 50% through its expected lifespan (per NAHB data — e.g., 13 years for a fridge, 10 for a washer), and the repair quote exceeds 50% of the cost of a comparable new unit. If only one is true, repairing is usually the better value.
Rarely. At 15 years it's already past the NAHB expected lifespan of 13, so any meaningful quote fails the age test, and older fridges cost noticeably more to run. Exception: a trivial fix (door gasket, condenser cleaning, ~$100–$200) on an otherwise healthy unit — or a built-in worth thousands to replace.
Usually no — 10 years is the full NAHB expected lifespan for a washer. A small fix (lid switch, hose, drain clog) can be fine; a pump, bearing, or control board job at $250–$400 is better spent on a new machine.
Anything in the first half of its life with a quote under 50% of replacement — and, at any age, cheap high-success fixes: gaskets, fans, fuses, hoses, igniters, drain clogs. Least worth repairing: countertop microwaves (repair ≈ replacement price) and any standard fridge needing sealed-system work.
Yes. Compressor and insulation tech improved dramatically, so a 15+ year-old fridge can use roughly double the electricity of a new ENERGY STAR model — often $40–$100+ per year in extra running cost, depending on your rates. Factor it into any borderline decision.
Smart next step

Price the part before accepting a full-service quote — RepairClinic matches parts to your exact model number and shows the install video, which is often the difference between a $60 part and a $300 service visit.
If your appliances are clustering past their half-life, read are home warranties worth it before the next breakdown, and check the full cost tables so the next quote never surprises you.
