Energy bills & appliances

Decode fixed charges, energy rates, time bands, labels, EV charging and heating without a made-up global tariff.

Answer first

Start with the bill line you are trying to change

A total electricity bill can combine energy use, fixed charges, taxes, adjustments and account-specific items. Begin with the exact decision: explain a past bill, price one appliance, or compare two plans. The correct rate and formula depend on that boundary, so GharGanit keeps each part visible instead of turning the whole bill into one unexplained price.

Decision boundary: The calculators organise arithmetic; they do not decide a billing dispute, diagnose an appliance or claim that one national average is the household tariff.

Common mistakes this workspace prevents

  1. 01

    Using the whole-bill average as the price of the next kWh without checking fixed lines.

  2. 02

    Applying an off-peak rate to consumption that remains in the peak period.

  3. 03

    Entering cooling output, heater output or power-supply capacity as appliance input watts.
