LT I(B): LT - Residential (Single Phase) · Maharashtra⚡ 200 units this month · avg rate ₹11.17/unit

View the tariff source ↗✓ Checked against the order in October 2026. Energy, wheeling and fixed charges match the FY 2026-27 LT table in the order. Duty is charged on consumption charges (energy, wheeling, fixed and fuel adjustment) under the Maharashtra Electricity Duty Act, 2016. Industrial duty of 7.5% is from MSEDCL Commercial Circular 329 (2020). The 16% residential and 21% commercial duty rates are the commonly billed rates but were not confirmed against the government notification, and the monthly fuel adjustment charge is not included.
This calculator turns monthly units into an estimated electricity bill using the slab rates set by each state's electricity regulator. It shows each part of the bill separately: energy charge slab by slab, fixed charge, any per-unit wheeling or fuel adjustment charge, and electricity duty. Every result names its tariff source and says whether the figures for that state have been checked against the current order.
How an Indian Electricity Bill Is Built
- Energy charge: units multiplied by the slab rates. Most domestic tariffs are telescopic, so each block of units pays its own rate.
- Fixed or demand charge: a monthly amount per connection, or per kW or kVA of sanctioned load, paid whatever you use.
- Wheeling charge: a per-unit charge for the distribution network, billed separately in some states such as Maharashtra.
- Fuel adjustment charge: a per-unit amount revised through the year to pass on fuel and power purchase costs.
- Electricity duty: a state tax. Its rate and the charges it applies to are set by state law and differ between states and categories.
Worked Example: Maharashtra, 250 Units
MSEDCL residential, single phase, FY 2026-27 rates from MERC's order in Case 75 of 2025: energy charge ₹3.96 for the first 100 units and ₹10.80 for 101–300, wheeling ₹1.60 per unit, fixed charge ₹130 a month, and electricity duty at 16% of consumption charges.
| Item | Working | Amount |
|---|---|---|
| Energy, first 100 units | 100 × ₹3.96 | ₹396.00 |
| Energy, next 150 units | 150 × ₹10.80 | ₹1,620.00 |
| Wheeling | 250 × ₹1.60 | ₹400.00 |
| Fixed charge | Single phase | ₹130.00 |
| Electricity duty | 16% × ₹2,546.00 | ₹407.36 |
| Estimated bill | ₹2,953.36 |
That is about ₹11.81 per unit on average. At 100 units the same tariff gives ₹795.76: energy ₹396, wheeling ₹160, fixed ₹130 and duty ₹109.76. The fuel adjustment charge on your bill comes on top, and duty applies to it as well.
Telescopic and Non-Telescopic Slabs
With non-telescopic slabs, one extra unit that crosses a boundary can raise the whole bill noticeably, because every unit moves to the higher rate. The result panel shows the billing type for the category you pick.
Getting a Closer Estimate
- Use the units from your meter reading or the "units consumed" line on your bill, for one month. If you are billed every two months, enter half and double the result, or check whether your state uses two-month slabs.
- Pick the exact category on your bill, including single or three phase where the tariff separates them.
- For load-based fixed charges, enter your sanctioned load in kW.
- Open Customize and add your bill's current fuel adjustment charge, or correct any rate that has changed.
This is an estimate, not your bill. Rates for states not yet marked as checked may be out of date; the result panel says which. Always compare with your latest bill or your distribution company's published tariff.

Electricity Bill Questions
How do I work out my bill from units?
Pick your state and connection category, then enter the units (kWh) from your meter or last bill. The calculator applies the slab rates, adds the fixed charge and any per-unit wheeling or fuel charge, then adds electricity duty.
What is the difference between telescopic and non-telescopic billing?
In telescopic billing each block of units is charged at its own slab rate, so only the units above a threshold pay the higher rate. In non-telescopic billing, crossing into a higher slab moves all of the month's units to that slab's rate. The calculator shows which one your category uses.
Is electricity duty a percentage of the energy charge?
It depends on the state. In Maharashtra the Electricity Duty Act charges it on consumption charges, which include the fixed, energy and fuel adjustment charges. Other states use the energy charge, a per-unit amount, or exempt some categories. The calculator uses each state's rule where it has been checked.
What is the fuel adjustment charge (FAC)?
A per-unit charge or rebate that passes changes in fuel and power purchase costs through to consumers. It is revised often, sometimes monthly, so it is usually not part of the tariff order. Add your bill's current FAC under Customize for a closer estimate.
Why does my real bill differ from the estimate?
Bills can include items the tariff order does not fix: the current FAC, arrears, interest, prompt-payment rebates, government subsidies and security deposit interest. Rates also change when a new tariff order takes effect.
How current are the rates?
Each result shows its source. States marked as checked have been compared line by line with the tariff order named in the result; the others have not been re-checked yet and show a warning, so compare them with your bill.
What is sanctioned load?
The maximum load approved for your connection, in kW or kVA. It only affects the fixed or demand charge in categories that bill per kW; the energy charge depends on units used.
