This is an energy-charge estimate, not a full utility bill clone
Electricity bills often look confusing because the energy charge is only one part of the final payable amount. Slab rates, fixed charges, fuel surcharge, subsidy, meter rent, electricity duty, and delayed payment charges can all sit around the main consumption figure.
This page focuses on the slab-based energy-charge estimate for the supported states shown in the form. It is useful for planning household or shop usage, but it is not meant to replicate every line item on the final bill.

What this page helps you do
- Estimates slab-based energy charges for the supported states on this page.
- Lets you compare domestic and commercial style consumption patterns where supported.
- Shows the slab-wise rupee contribution so the bill logic is easier to understand.
Examples
Small household
- Consumer type: Domestic
- Units: 180 units
Use the slab breakdown to see which portion of the bill remains in lower bands and what happens if usage rises.
Larger household
- Consumer type: Domestic
- Units: 450 units
Higher consumption often pushes more units into upper slabs, so the average per-unit cost can rise faster than expected.
Commercial planning check
- Consumer type: Commercial
- Units: 600 units
Use this for a quick planning check, then compare it with the tariff sheet and actual bill structure for the connection category you use.
How to use this Electricity Bill Calculator
- Choose the supported state and consumer type.
- Enter the units consumed for the billing period you want to model.
- Read the slab-wise breakdown, then remember that the actual bill can still include non-energy charges outside this page.
Why actual bills can differ from the energy-charge estimate
Slab billing means different blocks of consumption can be charged at different rates instead of applying one flat rate to all units. That is why the breakdown table matters more than a single units x rate shortcut.
This page uses the reviewed slab table for the supported state and consumer type. If your discom applies additional fixed or temporary charges, the final bill can be materially higher or lower than the energy-charge estimate shown here.
Common mistakes
- Assuming the bill is only units multiplied by one rate.
- Comparing this energy-charge estimate with a full bill that includes fixed and tax-style add-ons.
- Using monthly units when the actual bill is based on a different billing-cycle length.
Edge cases and limitations
- Different connection categories and special tariffs can sit outside the supported consumer types on this page.
- Temporary tariff orders and local subsidy changes can alter the final bill even when unit consumption stays the same.

This page uses a reviewed slab table for the supported states and consumer types. It estimates only the energy-charge portion of the bill so the user can see slab behavior clearly.

Questions that usually come up
- Why does my actual bill differ from this estimate?
- Because the final bill can include fixed charges, subsidy adjustments, fuel surcharge, electricity duty, meter rent, and other items that are deliberately excluded here.
- Does this page use slab billing?
- Yes. The result breaks the estimate into slab segments instead of using one flat rate for all units.
- What states are supported?
- Only the states shown in the form are supported by the current tariff table used on this page.
- Can I use monthly units for a two-month bill cycle?
- Not directly. Enter the units for the billing period you want to model, not an unrelated monthly average.
- Does it include subsidy or tax?
- No. Those items are intentionally excluded so the page stays clear about what it is estimating.
