When Appliance Repair Costs More Than Replacement
A technician is standing in your kitchen and has just said a number. You have about thirty seconds to decide whether to spend it or start over, and you have no idea which is right.
Here is a framework that removes the guessing.
The 50% rule (and the part everyone forgets)
The standard rule of thumb:
If the repair costs more than 50% of a comparable replacement, replace it.
That’s a decent starting point, but on its own it’s incomplete, because it ignores how much life the machine has left. A $300 repair on a two-year-old washer is excellent value. The same $300 repair on a twelve-year-old washer is money you will probably lose.
So adjust the threshold by age:
| Appliance age | Repair if it costs less than… | Reasoning |
|---|---|---|
| Under 5 years | ~60% of replacement | Lots of life left. Repair it |
| 5–8 years | ~50% of replacement | The standard rule applies |
| 8–12 years | ~30% of replacement | Getting close to the end. Be picky |
| Over 12 years | ~20%, or just replace | You’re buying a few years at best |
A cleaner way to think about it: divide the repair cost by the years you realistically expect to get from it. A $400 repair that buys eight more years is $50 a year, which is excellent. A $400 repair that buys two more years is $200 a year, and a new machine at $900 over twelve years is $75 a year. The new machine wins.
Typical lifespans (so you know where you are)
| Appliance | Typical life | Replacement cost |
|---|---|---|
| Refrigerator | 12–15 years | $800–$1,600 |
| Range / stove | 13–15 years | $650–$1,300 |
| Washer | 10–13 years | $700–$1,200 |
| Dryer | 10–13 years | $600–$1,100 |
| Dishwasher | 9–12 years | $500–$850 |
| Microwave | 7–10 years | $80–$450 |
| Freezer | 15–20 years | $300–$700 |
Full detail: how long do appliances really last?
The repairs that are almost never worth it
Some failures are effectively terminal. If you hear one of these on an older machine, the decision is largely made:
- Compressor or sealed system (fridge/freezer): $500–$1,200. On anything over about 8 years, replace. This is the classic case.
- Cracked glass cooktop: $250–$500 for the glass alone, plus labor. It’s also a shock hazard. Usually replace.
- Control board on an older appliance: $250–$500. On a 10+ year machine, that’s money into a dying asset.
- Washer transmission or drum bearings: expensive, labor-heavy. Rarely worth it past 8 years.
- Dishwasher tub cracked or rusting: the tub is the machine. Replace.
- A microwave, almost anything. A magnetron or control board repair often approaches the price of a new microwave. Microwaves are usually replace-not-repair items, and that’s fine, they’re cheap.
- Gas leak inside the appliance body on an older unit. Don’t chase gas leaks around a fifteen-year-old range.
The repairs that are almost always worth it
Conversely, don’t let anyone talk you into replacing a machine over these:
- Dryer: thermal fuse ($10–$20 part), igniter, heating element, thermostat, belt, rollers. A dryer is the most repairable appliance you own. See dryer not heating.
- Stove: igniter, burner cleaning, coil element, temperature sensor. Often free or cheap. See stove burner won’t light.
- Washer: drain pump, lid switch, hoses, and clogged filters. See washer not draining.
- Dishwasher: the filter (free), spray arms, the door gasket.
- Fridge: door gasket, defrost drain, condenser coils (free), fans, start relay. See refrigerator repair.
The pattern: mechanical and consumable parts are cheap and worth fixing. Sealed systems and electronics are expensive and often terminal.
The costs nobody includes (but should)
A repair decision isn’t just the invoice.
- The diagnostic fee. Often $70–$120, and usually credited toward the repair if you proceed, which quietly biases you toward saying yes. Ask whether it’s credited before you book.
- The risk of a second repair. An old machine that needed one part is more likely to need another. You could spend $350 today and $400 in eight months.
- Efficiency. A 15-year-old fridge can cost noticeably more per year to run than a modern one. A very old freezer can cost $120–$200 a year in electricity.
- Your time and the disruption. Waiting a week for a part, with no fridge, has a real cost.
- What a replacement actually costs you. This is the one that changes the math most, see below.
The thing that flips the calculation
Every repair-versus-replace calculation compares the repair against the price of a new appliance. But that’s not your only option, and it’s usually not the cheapest one.
If a comparable replacement is a $700 scratch-and-dent unit rather than a $1,300 new one, the 50% threshold drops from $650 to $350. Suddenly that $500 control board repair on a 10-year-old machine is clearly the wrong call, when against a new-only comparison it looked borderline.
- Scratch-and-dent: a new appliance with cosmetic damage, usually on a panel that’s hidden once installed. 20–40% off, normally with a warranty. See best brands for scratch-and-dent deals.
- Quality-tested used: 40–60% off new retail.
Run the 50% rule against what a replacement really costs you, not against showroom sticker prices. It will push you toward replacing sooner, and toward spending less when you do.
The decision, in six questions
- How old is it? Compare against the lifespan table above.
- What’s the repair quote, all-in? Parts, labor, diagnostic fee.
- What would a replacement actually cost me? Including scratch-and-dent and tested used.
- Is the repair under my age-adjusted threshold? (60% / 50% / 30% / 20%.)
- Is this failure on the "never worth it" list? Compressor, cracked cooktop, control board on an old unit.
- Has it needed other repairs recently? Two or more in a year is the machine telling you.
If you’re still torn, repair it. The downside of a repair that only buys you two years is modest. The downside of replacing a machine that had five good years left is a whole appliance.
And when it is time, don’t panic-buy: how to budget for new appliances.
Frequently asked questions
When is an appliance repair not worth it?
When it costs more than about half the price of a comparable replacement, and that threshold should drop with age: around 60% under 5 years, 50% at 5 to 8 years, 30% at 8 to 12 years, and 20% or less past 12. Certain failures are terminal regardless: compressors, cracked glass cooktops, and control boards on older machines.
What is the 50% rule for appliance repair?
If the repair costs more than 50% of what a comparable replacement would cost, replace instead. It’s a good starting point but incomplete on its own, because it ignores remaining lifespan. A better test is cost per remaining year: a $400 repair buying eight years is $50 a year; the same repair buying two years is $200 a year, and a new machine beats that.
Which appliance repairs are always worth doing?
Mechanical and consumable parts. On a dryer: the thermal fuse, igniter, heating element, thermostat, belt. On a stove: igniter, burner cleaning, coil elements. On a washer: the drain pump, lid switch, and clogged filters. On a fridge: gaskets, the defrost drain, fans, and cleaning the coils. These are cheap and extend the machine’s life meaningfully.
Is it worth repairing a microwave?
Usually not. A magnetron or control board repair often approaches the cost of a new microwave, and microwaves are inexpensive to replace. They’re one of the few genuinely replace-rather-than-repair appliances, and that’s fine.
Does the diagnostic fee change the decision?
It can, subtly. A $70 to $120 diagnostic fee is often credited toward the repair if you proceed, which nudges you toward saying yes even when replacing is the better call. Ask whether it’s credited before you book, and make the repair-versus-replace decision on the merits.
Should I compare repair cost to a new appliance or a used one?
To what a replacement actually costs you, which for most people includes scratch-and-dent and quality-tested used options. If a comparable replacement is $700 rather than $1,300, your 50% threshold falls from $650 to $350, and a borderline repair becomes an obvious no.
