- Compare a normal month and a high-usage month to see where slab pricing starts hurting.
- Use the related guides below if you need to understand fixed charges, energy charges, or 1 kWh cost.
Unit Rate Table
| Category | Approximate Rate |
|---|---|
| Domestic | Rs 6.90/kWh |
| Commercial | Rs 10.35/kWh |
| Industrial | Rs 8.28/kWh |
Use the domestic rate as a quick estimate. Final billing may differ based on official slabs and surcharges.
Slab Explanation
- Lower monthly usage usually stays in a cheaper slab band.
- Once consumption crosses the next slab, the effective average cost rises.
- Fixed charges remain even when usage is low, so the bill does not fall in a straight line.
- Commercial and industrial consumers can have different rate bands from domestic users.

- Estimate the bill once with your current month units and once with 10 to 15 percent higher usage.
- Keep fixed charges in mind, because low-usage months do not reduce the bill in a straight line.
- Compare the estimated power cost with the rest of your monthly budget if electricity is one of your larger household expenses.
Example Calculation
- 100 units x Rs 6.90 = Rs 690 energy charge
- Fixed charges add to the bill even if usage stays low
- Taxes and provider charges can move the final estimate upward
- Use the calculator to compare a low-usage and high-usage month side by side
