Should You Repair or Replace a Home Appliance?
Quick Answer
A useful rule of thumb is the "50% rule": if a repair costs more than roughly half the price of a comparable new appliance, replacement is often worth considering — especially as the unit ages. Other factors include the appliance's age relative to its typical service life, whether a newer model would meaningfully cut energy costs, and whether replacement parts are still available. Use our Repair vs. Replace calculator to frame the numbers for your specific situation.
Warning signs it may be time
No single symptom forces a replacement decision, but certain patterns make it worth taking the question seriously:
- Repeated failures within a short period. Two or three significant repairs in a year or two signal that the appliance is wearing out across multiple components, not just one.
- A repair estimate that surprises you. When the technician's quote is a significant fraction of what a new unit costs, the math often shifts toward replacement.
- Declining performance that can't be fully repaired. A refrigerator that can't hold temperature consistently, or a washer that still takes too long after repairs, may have underlying issues that one repair won't fully address.
- Parts are no longer available. Once a model is discontinued and spare parts are backordered or gone, repair becomes impractical regardless of cost.
- Safety issues. Appliances that have known safety recalls or that present ongoing hazards should be replaced rather than continually patched.
Repair vs. replacement
The most widely used framework is the 50% rule of thumb: if a repair will cost more than roughly half the price of a comparable new replacement, lean toward replacing — especially as the appliance ages. This is a common industry guideline, not a universal law, but it's a useful anchor for the conversation.
Age matters as much as the repair price. A repair that costs 30% of replacement value is a reasonable investment in a 2-year-old appliance. The same cost in a unit that's already well past its typical service life is a different situation — you're investing in an appliance that may need another repair in a year.
Use our Repair vs. Replace calculator to work through the trade-off with the specific numbers for your appliance. The calculator factors in both the repair cost and the unit's age relative to its service life.

Expected lifespan
Appliance lifespans vary widely depending on use intensity, water quality, maintenance history, and build quality. The figures below are general reference ranges — they are not guarantees and your unit may last shorter or longer.
- Refrigerators: Often 10–18 years, depending on the type and how well the condenser coils are maintained.
- Dishwashers: Commonly 9–13 years; filter maintenance and water hardness affect longevity.
- Washing machines: Typically in the range of 8–14 years; front-loaders and top-loaders have different failure patterns.
- Clothes dryers: Often 10–14 years; regular vent cleaning extends service life and prevents the overheating that shortens it.
- Gas ranges and ovens: Frequently 13–18 years; the burners and oven elements are generally among the simpler components to replace.
These ranges are meant as context for the repair-vs-replace conversation, not as predictions for your specific appliance. An 8-year-old refrigerator in perfect condition with clean coils is a different situation than an 8-year-old unit that has already had two compressor repairs.
What affects replacement cost
If you decide replacement makes sense, several factors affect what you'll pay:
- Appliance type and size. A basic top-freezer refrigerator costs significantly less than a large French door model with an ice maker. Match the replacement to your actual needs rather than defaulting to the largest or most feature-rich option.
- Energy efficiency. ENERGY STAR certified models carry a premium upfront but may offset some of that cost through lower operating expenses over time, particularly for refrigerators, dishwashers, and washers that run daily.
- Delivery, installation, and haul-away. These fees add to the purchase price and vary by retailer and region. Get total-cost quotes, not just appliance prices.
- Rebates and incentive programs. Utility companies and some state programs offer rebates for replacing old inefficient appliances with ENERGY STAR certified models. Check with your utility and visit ENERGY STAR's rebate finder before purchasing.
Professional installation
Most large appliances require some level of professional or at-minimum careful installation:
- Gas appliances (dryers, ranges, water heaters) must have gas connections made or verified by a licensed professional. Do not connect or disconnect a gas supply line unless you are qualified to do so.
- Dishwashers and washing machines involve both plumbing and electrical connections. Installation mistakes can cause water damage or electrical hazards.
- Refrigerators are typically the simplest to install (roll into position and plug in), but water line connections for ice makers and water dispensers should be made carefully and checked for leaks.
Ask the retailer whether installation is included or available as an add-on. Many appliance retailers include basic installation and old-unit haul-away in the purchase price.
If you are still diagnosing whether the appliance actually needs a repair, see the relevant troubleshooting guide: refrigerator not cooling, dishwasher not draining, washer not spinning, or dryer taking too long to dry.
Frequently asked questions
What is the "50% rule" for appliances?
The 50% rule is a common rule of thumb — not a hard standard — that suggests repair may not be worthwhile if the repair cost exceeds roughly 50% of what a comparable new appliance would cost. It's a useful starting point, but age matters too: a repair that costs 40% of replacement on a 15-year-old appliance past its typical service life is a different calculation than the same repair on a 3-year-old machine.
How do I find out how old my appliance is?
Most appliances have a data plate or label (usually inside the door or on the back of the unit) that includes the serial number. Many manufacturers encode the manufacture date in the first few characters of the serial number. Your owner's manual may explain the format, or you can search for your brand and serial number format online.
Does replacing an old appliance actually save money on energy?
It can, particularly for refrigerators, dishwashers, and washing machines, which run frequently. ENERGY STAR certified models are tested to meet efficiency standards above federal minimums. Whether the savings justify the replacement cost depends on how much you use the appliance, your energy rates, and how inefficient the old unit is. The numbers are worth checking before deciding.
What if replacement parts are no longer available?
Parts availability becomes a real constraint once an appliance model is discontinued or reaches a certain age. If a technician tells you a key component is backordered indefinitely or no longer manufactured, that changes the repair calculation significantly — replacement may be the only practical path forward.
Should I replace an appliance if it keeps breaking down?
Repeated failures are a signal that the appliance is past its reliable service life. If you have paid for two or more significant repairs in recent years and face another, the cumulative cost of repairs may exceed what a replacement would have cost. Factor in the disruption and uncertainty of ongoing unreliability, not just the repair invoice.
