Enter power and time—or known energy
Use the nameplate for a simple estimate or measured cycle energy when available.
Power × time × your rate
See what an appliance uses—and what that energy costs.
Start from rated power and runtime or from measured Wh/kWh per use. EnergyCost shows per-use, daily, selected-period, and 365-day energy and cost with the formula visible. Inputs stay on the page; there is no account, backend calculation, saved result URL, regional tariff guess, or dependence on the computer clock.
No account, upload, history, bill import, or generated result page.
Three visible inputs
Enter, calculate, verify
Describe actual usage and rate
Set quantity, uses per day, period, and the price per kWh from your own tariff.
Check formula and boundaries
Compare the answer with meter data and account separately for tiered or fixed bill components.

Keep every assumption visible
Enter power or measured energy, your actual usage, and the price from your tariff. EnergyCost calculates locally and keeps the formula beside the answer.
