All Electricity Calculators
Use these tools to estimate electricity bills, convert watts into units, compare appliance running costs, and size rooftop solar for Indian homes.
How to get a useful estimate
Use actual values from your bill whenever possible. For total bill estimates, enter consumed units, fixed charge, and duty. For appliance estimates, read the wattage label and estimate real daily usage hours. For solar, use a 12-month average bill instead of only one unusually high summer month.
Most Indian bills include slab rates, fixed charges, taxes, and sometimes fuel adjustment charges. A simple calculator gives a practical estimate; the linked state guides explain the detailed slab rules.
