Understanding Your Electricity Bill
An electricity bill usually contains more than the cost of the energy you consume. It may include a per-unit tariff, fixed service charges, government taxes, fuel price adjustments, meter-related charges, previous balances, and discounts. This Electricity Bill Calculator lets you include these values so your result is more useful than a simple units-to-cost estimate.
Basic Electricity Bill Formula
Total Bill = Energy Cost + Taxes + Fixed Charges +
Adjustments + Previous Balance − Discount
How to Calculate Electricity Units
Electricity consumption is normally measured in kilowatt-hours, commonly shown as kWh or units. When you have meter readings, subtract the previous reading from the current reading.
Meter Reading Formula
Units Consumed = Current Meter Reading − Previous Meter Reading
What Is the Cost per Electricity Unit?
The per-unit electricity rate is the price charged for one kilowatt-hour. Your provider may use a single tariff or different tariff slabs based on total monthly consumption. For the closest estimate, enter the effective rate shown on your electricity bill.
