Geyser Electricity Cost Calculator

Estimate water-heater electricity consumption and monthly running cost.

How it is calculated

Heat energy (kWh) = litres × 4.186 × temperature rise ÷ 3600, divided by heater efficiency, plus standby losses.

Results are indicative planning estimates, not official invoices. Actual bills depend on your DISCOM's current tariff order, subsidies, meter charges, time-of-day rules and taxes.
