Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Annual savings = (old kWh − new kWh) × electricity price + maintenance savings. Net cost = purchase cost − rebate. Break-even = net cost ÷ annual savings.

FAQ
Appliance Break-Even Calculator questions
Should installation cost be added?+
Yes. Include required delivery, installation and modification costs in the purchase-cost field.
What if the old appliance still works?+
Compare the remaining useful life and repair risk, not only energy savings.
Does a negative ten-year value mean replacement is always a bad choice?+
No. Reliability, performance, safety and required replacement timing may still justify the purchase.
