How do I know when to repair versus replace an appliance?

A common rule of thumb is the 50% rule: if the repair cost exceeds 50% of the cost of a new appliance, replacement usually makes more sense. Also factor in the appliance's age relative to its expected lifespan. If a washing machine typically lasts 10-12 years and yours is 9 years old, even a modest repair may not be worth it since other components will likely fail soon. Consider energy efficiency too, since older appliances often cost significantly more to run than newer models, meaning replacement can pay for itself over time. For newer appliances still under warranty, repair is almost always the right call. When in doubt, get a repair estimate first before committing to either decision.
