Should You Repair or Replace an Appliance?

Why the “50% rule” is too crude

You will often hear a rule such as “replace the appliance if the repair costs more than half of a new one.” It is easy to remember, but it hides the variable that matters most: how much additional useful life the repair is likely to buy.

A $500 repair that credibly buys five more years can be a different decision from the same $500 repair on an appliance likely to fail again next year. The replacement price matters too, but price alone does not tell you the value of the repair.

Compare cost per expected useful year

The calculator annualizes each immediate choice instead of pretending that a repaired old appliance and a brand-new appliance have the same remaining life.

This is deliberately simple. It makes your lifespan assumptions visible instead of burying them inside a rule of thumb.

The breakeven question is more useful

Instead of asking whether a repair is “too expensive,” ask: How many additional years does this repair need to buy before it is competitive with replacement?

If your repair needs to last only 1.5 years to break even and the technician believes the rest of the appliance is in good condition, the repair case is stronger. If it needs six more years from a machine already experiencing repeated failures, replacement may be more defensible.

Use actual replacement cost, not the advertised price

Delivery, installation, haul-away, required hoses or cords, cabinetry changes, and taxes can make the replacement decision more expensive than the sticker price. Include costs that are truly required for the option you are considering.

Energy savings are real—but use them carefully

The FTC's EnergyGuide labels show estimated annual energy use or operating cost for many major appliances and make it easier to compare similar models. The FTC also cautions that the annual operating cost on the label is an estimate based on standardized use and energy prices; your actual cost depends on how you use the appliance and your local utility rate.

That makes EnergyGuide a useful input, not a promise. For a refrigerator that runs continuously, operating-cost differences may matter more than they do for an appliance used only occasionally.

Reliability and downtime are legitimate costs

The calculator does not invent a dollar value for a future breakdown. But repeated failures, hard-to-find parts, food loss from a refrigerator outage, laundromat trips, missed work, or long service delays can matter. If the dollar result is close, those practical costs can reasonably drive the decision.

Use a range instead of one lifespan guess

Run the calculator at an optimistic and pessimistic repaired-life estimate. If “repair” wins only when you assume five more years but “replace” wins at two or three years, you have identified the real uncertainty. The next useful question for the technician is not “Is this worth fixing?” but “What else is likely to fail, and how confident are you that this repair buys several more years?”
