The washer stops mid-cycle, the technician comes out, and the quote lands on the counter: $300. Repair or replace the appliance? Most people decide on instinct, or on how old the machine feels. There is a better way, and it takes two numbers you already have: the quote, and the price of a comparable new model. Run them through two simple tests and the answer is usually clear before you have even called a second repair shop.
Repair or replace an appliance: the two tests
The first test is the one most people have heard of. Consumer Reports’ rule of thumb is not to spend more than 50% of the cost of a new product on repairing an old one (Consumer Reports). It is usually applied together with age: once an appliance has passed about half of its expected life, a repair costing more than half the price of new is a signal to replace.
The rule is useful because it is quick, but it has a blind spot. It compares a quote with a price without asking how many years each one buys. A $400 repair on a machine that will run another eight years is a much better deal than the same $400 on one with two years left, and the 50% rule treats them the same.
That is what the second test fixes. It turns both options into a cost per year of service. The repair costs its quote divided by the years the appliance can be expected to keep running. The new model costs its price divided by its expected lifespan. Whichever is cheaper per year of use is the better buy, all else being equal. When the two tests agree, the decision is easy. When they disagree, you are in a close call, and the rest of this article is about how to settle it.
How long appliances actually last
Both tests need an expected lifespan. The most widely cited reference is the National Association of Home Builders’ Study of Life Expectancy of Home Components, based on a survey of manufacturers, trade associations and researchers (NAHB study). Its averages for the major appliances:
| Appliance | Average lifespan (NAHB) | Half its life |
|---|---|---|
| Gas range | 15 years | 7.5 years |
| Refrigerator | 13 years | 6.5 years |
| Clothes dryer | 13 years | 6.5 years |
| Washing machine | 10 years | 5 years |
| Dishwasher | 9 years | 4.5 years |
| Microwave oven | 9 years | 4.5 years |
Two cautions come with that table. The study dates from 2007, and appliances have changed since; treat the figures as orders of magnitude, not guarantees. And the NAHB itself notes that the life of an appliance depends to a great extent on the use it receives and on maintenance, and that many are replaced long before they wear out because newer models become more desirable. A washer run twice a day for a family of five will not reach the same age as one run twice a week.
A worked example: the 7-year-old refrigerator
Take a refrigerator with an expected life of 13 years, now 7 years old, with a $300 repair quote. A comparable new model costs $900.
The 50% test: $300 is a third of $900, below the 50% threshold, even though the refrigerator is past half its life. Verdict: repair.
The cost-per-year test: the refrigerator can be expected to run about 6 more years, so the repair costs $300 / 6 = $50 per year of service. The new one costs $900 / 13 = about $69 per year. Verdict: repair.
Both tests agree, and the repair is the better buy by about $19 a year. The same refrigerator at 11 years old with a $250 quote would be a different story: $250 over roughly 2 years left is $125 a year, far above the $69 of a new one, even though $250 is well under 50% of the price. That is the case the 50% rule misses and the second test catches.
The most a repair is worth, year by year
Turning the second test around gives a useful ceiling: the highest quote that is still worth paying at each age. For the same $900 refrigerator with a 13-year life:
| Age of the refrigerator | Years left, roughly | Highest quote worth paying |
|---|---|---|
| 3 years | 10 | $692 |
| 5 years | 8 | $554 |
| 7 years | 6 | $415 |
| 9 years | 4 | $277 |
| 11 years | 2 | $138 |
Chart
The highest repair quote worth paying, by age
$900 refrigerator, 13-year expected life: quote per year left vs price of new per year.
The line falls steadily because each year of age removes a year of service the repair can buy. Early in an appliance’s life, even an expensive repair is worth it; near the end, a small one may not be. Keep that curve in mind when a technician tells you a repair is “only” $200 on a machine that has already outlived its average.

When the two tests disagree
A close call usually looks like this: an appliance past half its life, a quote a little above 50% of the price of new, and a cost per year that is roughly the same either way. In that zone, three questions settle it better than any formula.
Is this the first breakdown or the third? An appliance that has been reliable and fails once, on a part that wears out normally, is a good candidate for repair. One that has needed a technician every year is telling you something, and the next quote is probably coming.
What does it cost to run? An old refrigerator or freezer can use far more electricity than a new efficient one. Measuring it for a few days with a plug-in electricity monitoraff. turns that suspicion into a number, and the appliance electricity cost calculator converts the kWh into dollars a year at your state’s price. If the old one costs $60 a year more to run than a replacement, that belongs on the replace side of the ledger.
What does a new one cost right now? New appliances have become slightly cheaper: the Bureau of Labor Statistics measured prices for major appliances down 1.9% over the twelve months to August 2026, while overall consumer prices rose 3.4% (BLS). A falling replacement price tilts close calls toward replacing, which is why the calculator asks for the price you actually found rather than assuming one.
Four common breakdowns, and how to read the quote
The same two tests apply everywhere, but some failures are far more common than others, and knowing the usual suspects helps you judge whether a quote is reasonable. Always start with the owner’s manual: most have a troubleshooting table that lists the likely causes of each symptom, and some of those fixes cost nothing.
A washing machine that stops mid-cycle full of water often points to the drain path: a clogged drain pump filter, which many front-loaders let you reach through a small door at the bottom front, or a kinked drain hose. Before paying for a new pump, it is worth checking what the manual says about cleaning that filter.
A dryer that tumbles but no longer heats commonly comes down to a heating element or a thermal fuse, both of which either conduct electricity or do not. That is exactly the kind of fault a continuity test settles, and it is why a quote for a “control board” on a dryer that simply stopped heating deserves a question.
A refrigerator that runs but no longer cools well can have something as simple as clogged condenser coils or a failing fan behind it, or something as expensive as a sealed-system problem with the compressor. The difference in price between those repairs is enormous, which is why the written diagnosis matters more than the total at the bottom of the page.
A dishwasher that leaves dishes dirty very often has a clogged filter, which the manual shows how to remove and rinse. It is the cheapest repair there is, and it is the first thing to rule out before accepting any quote.
Small machines follow a different logic. A coffee maker, a toaster or a microwave is rarely worth a technician’s visit, and repair is often not even offered. For those, the question is less “repair or replace” than “is this appliance worth owning at all”, which is the reasoning in the article on whether a coffee maker is worth it.
Check the diagnosis before you pay
A repair decision is only as good as the diagnosis behind it. Many common failures are electrical and simple to confirm: a heating element that no longer conducts, a blown thermal fuse, a door switch that no longer closes the circuit. A continuity test on an unplugged appliance shows whether current can pass through the part, and it takes a few minutes with the right tool. You do not need to do the repair yourself to benefit from it; knowing what was measured lets you ask the technician the right questions.

Getting to the part is often the real obstacle. Many appliance panels are held with Torx or other security screws, and a security bit setaff. is what separates “I can’t even open it” from “I can see what failed”. Before opening anything, unplug the appliance and, for a washer or dishwasher, shut off the water supply. And if it is still under the manufacturer’s warranty, do not open it at all: call the manufacturer first.
Maintenance: the cheapest repair is the one you avoid
The NAHB’s point that lifespan depends on maintenance is the most useful line in its whole study, because maintenance is the part you control. A refrigerator’s condenser coils clogged with dust make the compressor work harder; a condenser coil cleaning brushaff. and ten minutes once or twice a year keep them clear. A dryer’s lint screen and exhaust duct, a dishwasher’s filter and a washer’s drain pump filter all have the same logic: a cheap, regular gesture that keeps the machine away from the repair quote in the first place. The owner’s manual lists what the manufacturer recommends and how often.
To see what an old appliance really draws before deciding, a plug-in electricity usage monitoraff. left on for a week measures real consumption, compressor cycles and standby included. It is the number that most often turns a close call into a clear one.
Where this fits in the household budget
The same payment-versus-repair reasoning applies well beyond the kitchen. Replacing a paid-off car that still runs well, as the article on whether an electric car is worth it shows, is usually the same mistake as replacing a sound appliance: a new payment that costs far more than the problem it solves. For freezers specifically, whether a new efficient model is worth buying at all depends on what goes in it, as the chest freezer payback explains.
The guide to making things last puts repair decisions, maintenance and running costs in one place, and the page of savings calculators lists every other expense that can be run through a break-even. If appliances are only one of the lines that have grown this year, the personal inflation calculator shows where the rest of the increase comes from.
Frequently asked questions
- When should you repair or replace an appliance?
- Consumer Reports' rule of thumb is not to spend more than 50% of the cost of a new product on repairing an old one, and it applies most once the appliance has passed half its expected life. A second test compares the cost per year of service: the repair quote divided by the years the appliance has left, against the price of a new one divided by its lifespan. When both tests say repair, repair; when both say replace, replace; when they disagree, it is a close call.
- How long do major appliances last?
- The National Association of Home Builders' Study of Life Expectancy of Home Components gives average lifespans of about 13 years for refrigerators and clothes dryers, 10 years for washing machines, 9 years for dishwashers and microwave ovens, and 15 years for gas ranges. These are averages from 2007 that depend heavily on use and maintenance.
- Is it worth repairing a 7-year-old refrigerator?
- Often, yes. With an expected life of about 13 years, a 7-year-old refrigerator has roughly six years left. A $300 repair spread over six years costs $50 a year, against about $69 a year for a $900 replacement over 13 years, and $300 is a third of the price of new, below the 50% threshold. Both tests say repair.
- Are new appliances getting cheaper?
- Slightly. The Bureau of Labor Statistics measured prices for major appliances down 1.9% over the twelve months to August 2026, while overall consumer prices rose 3.4%. A cheaper replacement tilts close calls a little toward replacing, which is why the calculator asks for the price you found for a comparable new model.
- Should I repair an appliance that is still under warranty?
- Don't pay anything before checking. If the appliance is under the manufacturer's warranty, the repair may be covered, and opening it yourself can void that coverage. Call the manufacturer first with the model and serial number from the rating plate.
- How can I tell if the repair quote is right?
- Ask for the fault in writing and, for electrical faults, ask the technician to show the measurement. A basic continuity test with a multimeter, on an unplugged appliance, often confirms whether a heating element, a fuse or a switch has failed. Knowing what was measured is what lets you judge the quote.

I am not a financial adviser or an economist. I keep the books of an ordinary household, and I got tired of tip lists that never put a number on anything.

- I start from public data — federal fuel prices, the Consumer Price Index, Energy Star ratings — and I say where every figure comes from.
- Every calculation shows its assumptions. If your usage differs from my example, the calculator gives you your own break-even point.
