Appliance replacement payback calculator

Use annual kWh and net replacement cost to calculate payback from electricity savings alone.

Reading the result

Net cost = purchase + installation − old appliance proceeds. Annual energy saving = (old kWh − replacement kWh) × rate. Payback = net cost / annual saving. Non-positive savings cannot recover the cost through electricity.

Example: a net cost of 500 and annual savings of 40 gives 12.5 years. This is hypothetical arithmetic; it does not predict lifespan, inflation, rates or repairs.
