The 50% Rule
A widely accepted guideline is the 50% rule: if the repair cost exceeds 50% of the price of a new appliance, replacement is usually the better investment. However, this rule has nuances depending on the appliance type and age.
Average Appliance Lifespans
Understanding how long appliances typically last helps you make informed decisions:
- Refrigerator: 10-18 years
- Washer: 10-14 years
- Dryer: 10-13 years
- Dishwasher: 9-12 years
- Oven/Range: 13-15 years
- Microwave: 7-10 years
When to Repair
Consider repairing your appliance when it's less than halfway through its expected lifespan, the repair cost is under 50% of replacement cost, or if it's a high-end model that would be expensive to replace with equivalent quality.
When to Replace
Replacement makes more sense when the appliance is near or past its expected lifespan, needs frequent repairs, uses significantly more energy than modern models, or when parts are difficult to find.
Energy Efficiency Factor
Modern appliances are significantly more energy-efficient. A new ENERGY STAR refrigerator can save $100+ per year in electricity compared to a model from 15 years ago. Factor in potential energy savings when making your decision.
