Published prices and supplier examples

Each reference applies only to its stated period, area and customer profile. Fixed charges and partial bill components are shown for context; only comparable variable prices can be applied.

Tata Power-DDL · Delhi · 201–400 kWh/month
4.5 INR/kWh · Base schedule from 01 Oct 2021 · FY26 handbook
Domestic energy charge only, reproduced in the official FY26 customer handbook. This band applies within the household's monthly slab calculation, not to an appliance in isolation. Excludes fixed charges, PPAC/FPPAS, regulatory and pension surcharges, electricity tax and subsidies. The base schedule is published from 1 October 2021; verify current adjustments on your bill. This is not an all-India average or the full cost of a kWh.

Context only: this is not a complete variable price for estimating savings.
MSEDCL · Maharashtra · 101–300 kWh/month
10.8 INR/kWh · FY 2026–27 · from 01 Apr 2026
Domestic LT-I(B), sanctioned load below 20 kW, energy charge only. The applicable slab depends on the household's total monthly consumption. Wheeling of ₹1.60/kWh, fixed charges of ₹130/month (₹435 for three-phase), FAC, taxes and any subsidy are separate. This example is not a complete bill, supplier ranking or national average.

Your estimate

Estimate — adjust the assumptions to your situation.

Illustrative variable rate per kWh. Replace with your bill; fixed charges are excluded.

Set annual kilometres, EV consumption, electricity price, fuel consumption and price per litre. Use comparable routes and driving patterns for both vehicles. For the EV, a consumption figure measured from the grid includes the charging energy you actually pay for.

Formula

Annual EV cost = annual km ÷ 100 × kWh/100 km × electricity price. Annual fuel cost = annual km ÷ 100 × litres/100 km × price per litre. Saving = fuel cost − EV cost; percentage saving uses fuel cost as its baseline.

Worked example

Over 15,000 km, an EV using 18 kWh/100 km requires 2,700 kWh. A combustion vehicle using 6 litres/100 km requires 900 litres. Applying the respective unit prices gives a like-for-like annual energy comparison.

What the result means

A positive saving means lower energy spending with the electric vehicle under these assumptions. A negative result means the entered charging arrangement costs more than the fuel scenario.

Electricity price · India

Electricity duty, fuel or power purchase adjustments, fixed charges and subsidies depend on the applicable state and DISCOM rules. No national tax percentage or subsidy is assumed. Slab thresholds, sanctioned-load charges and time-of-day tariffs are not automatically modelled.

Assumptions and limits

This is an energy-cost comparison, not a total ownership forecast. Depreciation, purchase price, taxes, insurance, maintenance and infrastructure costs can change the overall decision.

Questions answered

Can I compare diesel instead of petrol?

Yes. Enter the diesel vehicle’s litres per 100 km and diesel price.

Does it include public charging fees?

Only the per-kWh price entered. Add other fees separately when assessing a real offer.
