Electricity-cost calculators for France

Use euros, your own tariff, and device-specific operating models—without pretending one national average fits every household.

Billing context

Use the rate that changes with consumption.

Regulated residential tariffs include a subscription charge and one or more per-kWh rates. Base, peak/off-peak, Tempo, supplier, and subscribed-power choices materially change the applicable price.

How to enter your rate

Use the TTC per-kWh rate for your exact option. PowerCost Lab may provide a current verified regulated-tariff reference, but your contract remains authoritative.

Local calculator

Electric heater

Direct electric heating cost depends on insulation, thermostat cycling, occupied rooms, contract option, and whether consumption occurs during peak or off-peak periods.

Calculate local cost ↗Local calculator

Water heater

Storage water heaters are often scheduled for off-peak operation, making contract option, tank losses, household demand, and control settings important.

EV charging

Home EV charging can shift substantial energy into off-peak periods, but contract option, battery conditioning, losses, and charge frequency determine the result.
