Your dishwasher dies on a Tuesday, right in the middle of a normal week, and suddenly you're standing in the kitchen doing math you never expected to do. Is it worth paying to fix it? Or is this the moment to just go buy a new one? You might start looking up the model number, checking how old it actually is, wondering if a repair is even worth the trouble. It's a more common moment than people realize, almost everyone with a house full of appliances runs into it sooner or later. The good news is that while there's no single rule that fits every situation perfectly, there is a simple, reliable way to think it through. It takes most of the guesswork out, so you're not just making a random guess under pressure.

Start With the 50% Rule

A widely used rule of thumb in the appliance world: if the repair cost is more than 50% of the price of a new comparable appliance, replacement usually makes more financial sense. If a $600 washing machine needs a $350 repair, you're inching close to just buying new. If that same repair is $120, fixing it is almost always the better move.

This rule isn't perfect on its own — it doesn't account for age or how many other issues might be lurking — but it's a solid first filter before digging into the details.

Factor In the Appliance's Age

Most major appliances have a general expected lifespan:

• Refrigerators: 10–18 years
• Washers and dryers: 10–13 years
• Dishwashers: 9–12 years
• Ovens and ranges: 13–20 years (gas ranges often last longer than electric)
• Microwaves: 7–10 years

If your appliance is well within its expected lifespan and otherwise reliable, a repair usually makes sense even if it costs a bit more than you'd like. If it's already near or past the upper end of that range, a repair is essentially a bet that nothing else fails soon after — a bet that doesn't always pay off.

Think About What Else Might Be Close to Failing

This is the part the 50% rule misses. An appliance that's had two or three unrelated repairs in the past couple of years is telling you something, even if each individual repair was reasonably priced. Compressor issues in an aging refrigerator, for example, are often a sign the whole system is wearing down, not an isolated failure — throwing money at each new symptom can add up to more than a replacement would have cost.

Ask a technician directly: if I fix this, does anything else look like it's close to going? A good technician will give you an honest read on this rather than just quoting the one repair in front of them.

Weigh the Cost of Downtime

Some appliances you can live without for a week or two without much disruption. Others — a refrigerator, especially — cause real problems fast: spoiled food, extra trips to buy ice or a mini fridge, disrupted routines. If parts availability is uncertain (common with older or discontinued models) and a repair could mean a week or more without the appliance, that's a real cost even if it's harder to put a number on than the repair bill itself.

Consider Energy Efficiency, Especially for Older Units

An appliance from 15+ years ago is very likely less energy-efficient than what's available today, sometimes significantly so. This doesn't override the math on an otherwise-healthy appliance with a minor repair, but for a unit that's already borderline on age, the ongoing energy savings from a newer model can help tip the decision, especially if you're weighing a repair that's already fairly costly.

When Repair Almost Always Wins

• The appliance is less than half its expected lifespan
• The repair is a relatively minor, well-understood fix (a belt, a seal, an igniter, a common part)
• The repair cost is well under the 50% threshold
• The appliance has otherwise been reliable, with no pattern of repeat issues

When Replacement Usually Makes More Sense

• The appliance is at or past its typical lifespan
• The repair cost approaches or exceeds half the price of a new one
• This isn't the first significant repair in the past year or two
• Parts are hard to find or on backorder for weeks
• You're already noticing other signs of wear (unusual noise, inconsistent performance, rising energy bills)

A Practical Way to Decide, Step by Step

1. Get an actual repair quote — don't estimate, get a real number from a technician
2. Compare that number to the price of a similar new model
3. Check where your appliance falls in its expected lifespan
4. Ask the technician if they see signs of other problems
5. Factor in how disruptive being without the appliance would be while you wait for parts

Running through these five steps takes maybe fifteen minutes and turns a decision that often feels like a coin flip into something you can actually be confident about.

There's No Shame in Either Choice

Repairing an appliance isn't automatically the "responsible" choice, and replacing one isn't automatically wasteful — both are reasonable depending on the specifics in front of you. The goal isn't to always fix things or always buy new; it's to make the call based on the actual numbers and condition of your appliance, rather than a gut reaction to an unexpected repair bill.
