Electricity-cost calculators for India

Use Indian rupees, 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.

Domestic tariffs are set by states and utilities and commonly use consumption slabs, fixed charges, duties, and subsidies. A single national household rate would be misleading.

Local calculator

Air conditioner

Air-conditioner cost in India is shaped by climate, inverter loading, room heat gain, long summer schedules, and state-specific consumption slabs.

Calculate local cost ↗Local calculator

Ceiling fan

Several fans running for long daily periods can create a meaningful seasonal load even when each individual fan uses relatively little power.

Water heater

High-power geysers operate for shorter periods, but thermostat losses, household size, inlet temperature, and slab escalation determine the bill impact.
