Repair vs. Replace: How to Decide for Any Appliance

Every homeowner eventually faces the same dilemma: your appliance breaks down and you have to decide whether to fix it or buy a new one. There's no universal answer — but there is a clear framework that makes the decision straightforward. Here's how to think through it for any appliance.

The 50% Rule

The most widely used guideline in appliance repair: if a repair costs more than 50% of the price of a comparable new appliance, and your current unit is more than halfway through its expected lifespan, replace it. This rule works because it accounts for both the repair cost and the remaining value of the appliance.

The Age Factor

Age matters as much as repair cost. An expensive repair on a nearly new appliance is almost always worth doing — you're restoring years of reliable service. The same repair on an appliance near the end of its life is buying you a few more years at best, and the next failure may not be far behind.

• Under 40% of expected lifespan: repair almost any problem that costs less than 70% of replacement
• 40–70% of expected lifespan: apply the 50% rule strictly
• Over 70% of expected lifespan: only repair simple, inexpensive issues — anything major favors replacement

Factor in Energy Efficiency

Older appliances are significantly less energy-efficient than modern equivalents. A 12-year-old refrigerator can use 40–50% more electricity than a current ENERGY STAR model. A 10-year-old washer may use twice the water of a modern HE machine. These ongoing operating cost savings should factor into your replacement decision — especially if the appliance is already failing.

A rough way to calculate: estimate the annual energy cost difference between your old appliance and a new equivalent model. Divide the price of a new model by its yearly energy savings to see how many years it takes to pay for itself purely through efficiency — before factoring in the avoided repair.

Consider Repair History

An appliance that has needed repairs multiple times is signaling systemic wear, and repeated failures are one of the signs a repair is not DIY. Each repair addresses a specific failed component, but doesn't stop other aging components from failing. If you've repaired the same appliance twice in two years, the third repair cost should be compared to replacement much more aggressively than a first-time failure.

Parts Availability

For appliances over 10–12 years old, parts may be discontinued, hard to source, or available only from third-party suppliers at premium prices. A technician who diagnoses a failed part but can't source it reasonably is giving you a de facto recommendation to replace. Always ask whether OEM parts are available before committing to an expensive repair on an older unit.

Quick Reference Decision Guide

• Simple, inexpensive repair on any age appliance: almost always repair
• Moderate repair on appliance under 8 years old: repair
• Moderate repair on appliance 8–12 years old: apply 50% rule
• Major repair on appliance under 5 years old: repair if under warranty or if cost is under 50% of replacement
• Major repair on appliance over 10 years old: replace in most cases
• Any repair on an appliance that has needed multiple repairs recently: strong lean toward replacement
