Estimate an electricity bill from units
Electricity consumption is commonly shown in kilowatt-hours (kWh), often called units on a household bill. A simple estimate multiplies units by the selected per-unit rate and then adds fixed or other charges entered. Actual bills may use different slabs for different portions of consumption.
Why the bill may differ
State distribution-company tariffs can include slab rates, fixed charges, fuel adjustment, electricity duty, meter rent, subsidies and time-of-use rules. Enter the charges that apply to your connection and check the latest tariff order or bill from your distribution company. This is a planning estimate, not a bill issued by the utility.
