About Appliance Cost Calculator

Appliance Cost Calculator is a utility site for UK households trying to understand everyday appliance running costs.

The site uses transparent formulae, editable calculator inputs, published assumptions and maintained source notes.

Calculations are estimates, not financial advice. Your own tariff, supplier, region, payment method and appliance behaviour can change the result.
