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.

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.

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

For an Indian household, estimate the extra units a fan uses before applying the relevant DISCOM tariff. One unit is one kWh. A seasonal schedule avoids treating a fan used for six months as a year-round load. Enter the electrical input at the speed you actually use; a label rating is not a measurement of every operating condition.

Formula

Energy in kWh = power in kW × hours of operation. A weekly schedule is multiplied by 365 ÷ 7; a monthly schedule uses days × 12, capped at 365. Cost = energy × price per kWh. With power and hours entered, the yearly schedule uses your exact number of operating days, without extrapolating the season to a full year.

Worked example

Ceiling-fan use across a cooling season

Hypothetical example, not a tested fan or a current Indian tariff: a 60 W ceiling fan running ten hours on 180 days uses 0.06 × 10 × 180 = 108 units per year. Choose Year and 180 days. At an assumed ₹8 per additional unit, the energy cost is ₹864 for the year, averaging ₹72 per calendar month. In a 30-day month of daily use, it consumes 18 units and costs ₹144 at that same assumed rate.

What the result means

If all 108 additional units face the same rate, multiplying by ₹8 is sufficient. If they cross a slab boundary, split the extra units by slab and sum their costs. For example, 10 extra units at an assumed ₹6 and eight at ₹8 cost ₹124, not 18 × ₹8 = ₹144. This is only an arithmetic illustration; thresholds, subsidies and billing rules depend on your DISCOM and category.

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

For a different fan, compare the same airflow requirement, speed and operating hours. Reducing input from 60 W to an assumed 35 W at the same schedule saves 45 units, or ₹360 at ₹8 per unit; it does not prove equivalent airflow. Use the appropriate BEE label and product data, and confirm your tariff's additional-unit rate. Fixed charges, subsidy thresholds and inverter losses are not automatically included in this calculator. BEE and bill-guidance sources are linked below.

Questions answered

Should I enter the appliance’s maximum power?

Measured average power is preferable when the appliance cycles or changes its output.

Does the cost include the whole electricity bill?

No. It estimates the variable energy charge at your chosen rate.
