Appliance Repair vs. Replace Calculator
When a major appliance breaks down, the repair-or-replace decision can significantly affect your household budget. Industry professionals use the 50% Rule as a starting guideline: if the repair cost exceeds 50% of the cost of a new appliance, replacement is generally the better financial choice. This calculator combines the 50% Rule with life-cycle cost analysis to give you a more complete picture.

Energy Comparison (optional)
The 50% Rule is a general guideline used by appliance professionals. Actual decisions should also consider reliability history, parts availability, warranty on the repair, and whether a new model offers meaningful efficiency improvements. Energy Star appliances may qualify for utility rebates that improve the economics of replacement.
The 50% Rule Explained
The 50% Rule is a widely used heuristic in the appliance repair industry: if the cost to repair an appliance exceeds half the cost of buying a new equivalent model, you should generally replace it. The logic is straightforward—why spend $600 repairing a $1,000 appliance when you could buy a new one with a full warranty for $1,000?
Age as a Factor
Age matters alongside the repair cost ratio. An appliance that has used more than 75% of its expected lifespan is nearing end-of-life even if repaired. A new part may outlast the machine itself, and other components are likely to fail soon. In that scenario, repair delays the inevitable while continuing to use an energy-inefficient unit.
Life-Cycle Cost Analysis
Beyond the immediate repair vs. purchase cost, energy consumption over the remaining life of each path tells the full financial story. A newer model may use 30–40% less electricity per year, making replacement cost-effective even when the repair quote alone might pass the 50% test. This calculator accounts for both repair cost and projected energy cost differences over the appliance’s remaining or full lifespan.
Average Appliance Lifespans
These expected lifespans come from the National Association of Home Builders (NAHB) and Consumer Reports research:
- Refrigerator: 13 years
- Clothes Dryer: 13 years
- Electric Range: 13 years
- HVAC System: 15 years
- Freezer: 11 years
- Clothes Washer: 10 years
- Water Heater: 10 years
- Dishwasher: 9 years
- Microwave: 9 years
Frequently Asked Questions
Does brand or model history affect the decision?
Absolutely. A premium appliance brand known for reliability and available parts may be worth repairing even at a higher cost ratio. A budget appliance with a history of recurring problems might warrant replacement below the 50% threshold. Check Consumer Reports reliability data and read reviews for your specific model before deciding.
Should I consider the warranty on the repair?
Yes. A reputable appliance service company should offer at least a 90-day labor warranty and parts coverage matching the manufacturer’s parts warranty (typically 1 year). If the repair comes with no warranty, the financial risk is higher, shifting the analysis toward replacement.
What about manufacturer rebates on new appliances?
Many utility companies offer rebates of $50–$300 for replacing old appliances with Energy Star-rated models. Federal tax credits may also apply to certain heat pump water heaters and HVAC systems under the Inflation Reduction Act (2023–2032). These incentives can make replacement significantly more attractive than the sticker price alone suggests.
