The Short Answer
Repair it if the machine is less than about two-thirds through its expected life and the fix costs under half the price of a comparable new one. Replace it when the repair costs more than 50% of replacement, the unit is past its typical lifespan, or the parts are discontinued. Age, repair cost, and parts availability make the call together. No single rule does the job alone, which is why the rest of this guide exists.
The 50% Rule, Explained Honestly
The 50% rule says: if a repair costs more than half of what a comparable new appliance costs, replace instead of repair. It is a genuinely useful rule of thumb, and it works because it bakes in the risk you are taking: an old machine that needed one repair is more likely to need another soon.
But apply it with judgment. A $200 repair on an $1,800 French-door refrigerator is 11%, an easy fix. A $400 sealed-system repair on a 14-year-old fridge is a different story even before you do the math. And the rule assumes the replacement is comparable: if you would replace a basic top-freezer with another basic top-freezer, compare those prices, not the price of the fanciest model in the store.
How Long Appliances Typically Last
Lifespans are averages, not promises. A well-kept machine beats these numbers; a neglected one never reaches them. Still, they anchor the decision:
| Appliance | Typical lifespan | Repair-friendly zone |
|---|---|---|
| Refrigerator | 10 - 15 years | Under ~10 years, usually worth fixing |
| Freezer (chest or upright) | 12 - 16 years | Under ~11 years, usually worth fixing |
| Washing machine | 8 - 12 years | Under ~8 years, usually worth fixing |
| Dryer | 10 - 13 years | Under ~9 years, usually worth fixing |
| Dishwasher | 9 - 12 years | Under ~8 years, usually worth fixing |
| Range / oven | 15 - 20 years | Under ~13 years, usually worth fixing |
| Microwave | 7 - 10 years | Under ~6 years, usually worth fixing |
| Garbage disposal | 8 - 10 years | Under ~7 years, usually worth fixing |
See our Spring Hill repair cost guide for what each type of fix typically runs, so you can do the 50% math with real numbers.
Repair It If...
If the numbers say fix it, our refrigerator repair, washer repair, and dishwasher repair services cover the calls we get most.
- The machine is comfortably inside its expected lifespan.
- The repair costs well under half of replacement.
- It is a premium brand (Bosch, KitchenAid, Speed Queen) where replacement costs two to three times the repair.
- The problem is a single failed part, not a cascade of wear.
- You like the machine and it fits the space. (Built-ins and odd sizes are expensive to replace.)
Replace It If...
- The repair costs more than 50% of a comparable new unit.
- The machine is past its typical lifespan and this is not its first repair.
- Parts are discontinued and the fix would rely on used or sketchy substitutes.
- It uses dramatically more energy or water than a modern equivalent. A 20-year-old fridge can cost noticeably more to run each year.
- Rust, a cracked tub, or a failing sealed system. Some failures are the machine telling you it is done.
When Parts Availability Makes the Decision for You
Sometimes the math never gets a chance. Control boards for 15-year-old machines get discontinued. Kenmore models built by long-gone OEM arrangements can hit dead ends. When we cannot source a reliable part, we tell you immediately and pivot the conversation to replacement. We check our brand and parts notes before we schedule, so you never pay for a diagnostic trip that was doomed from the start.
The Honest Environmental Note
Repairing keeps a few hundred pounds of metal, plastic, and refrigerant out of the waste stream, and we are genuinely in favor of fixing what can be fixed. The honest counterpoint: a new ENERGY STAR refrigerator or washer uses meaningfully less energy and water than a 15-year-old unit, so replacement is not automatically the wasteful choice. If you do replace, ask the retailer or hauler about recycling the old unit rather than sending it to a landfill.
A Spring Hill Example
Here is how this plays out locally. In Buckner Crossing, where the all-brick homes run 15 to 20 years old, we regularly see original-equipment dishwashers and disposals hitting end of life. A $180 pump on a 16-year-old dishwasher fails the 50% test and the age test, so we usually advise replacement. The same $180 pump on a 6-year-old machine in Cherry Grove is an easy fix. Same part, same price, opposite answers. Context is everything, and Quick Air Fix will walk you through yours for free.

Frequently Asked Questions
Is it worth repairing a 10-year-old refrigerator?
It depends on the failure. Ten years is mid-life for a fridge (typical lifespan 10-15 years). A defrost-system fix or a fan replacement is usually worth it. A sealed-system or compressor failure at that age usually is not, since that repair alone can approach half the cost of a new unit.
What is the 50% rule for appliance repair?
If the repair costs more than 50% of the price of a comparable new appliance, replace rather than repair. It is a rule of thumb, not a law: factor in the machine's age, whether parts are available, and whether this is the first repair or the third.
My appliance needs a part that is discontinued. What are my options?
Three, honestly: find a compatible substitute part (sometimes possible, sometimes not), buy a used part (risky, short warranty on the outcome), or replace the appliance. We check parts availability before scheduling, and if the part is gone, we will tell you straight instead of taking the job.
Are expensive brands worth repairing longer?
Usually, yes. A Bosch dishwasher or a KitchenAid built-in refrigerator costs two to three times what a basic model costs, so a $300 repair that would fail the 50% test on a budget machine passes easily on a premium one. The math follows the replacement price, not the repair price alone.
Will you give me honest advice even if it costs you the job?
Yes. We would rather tell you to replace a dying machine than take your money for a repair that buys you six months. Customers who get a straight answer call us back for the next repair, and they tell their neighbors. That is worth more to us than one job.
