Calculate

Appliance presetUse measured annual consumption

For fridges and cycling appliances, use measured or label kWh/year. For kWh/100 cycles, convert using your actual number of cycles.

Annual consumption (kWh)0 – 1,00,00,00,000

Electricity price (INR/kWh)0 – 10,000

Country reference price selected.

₹8.00/kWh is an illustrative input, not an India-wide average or an official electricity tariff. Replace it with the applicable rate for your state, DISCOM, consumer category and consumption slab.

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.

Annual200 kWh

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

Select an appliance as a starting point, then replace its example power and schedule with information for your model. A refrigerator, gaming PC and kettle use electricity differently: an example is a scenario to explore, not a specification or a promise of typical consumption.

Formula

Annual electricity use = power in watts ÷ 1,000 × daily operating hours × annual operating days. Annual cost = annual kWh × your electricity unit rate. Monthly figures are annual totals divided by 12. 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

A 100 W television running four hours every day uses 0.4 kWh on an operating day and 146 kWh in 365 days. Add standby separately if its off-hours consumption matters.

What the result means

Compare the result with a plug-in energy meter or the appliance’s energy label. For a refrigerator or freezer, a measured daily total is more informative than assuming its compressor operates continuously.

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

Programme length, temperature, load, settings and thermostat cycling affect consumption. Rated power alone does not reveal the energy used by one washing or drying cycle.

Questions answered

Can I change the suggested figures?

Yes. All example values should be adjusted to your appliance and actual habits.

How do I model intermittent operation?

Use measured average power over the chosen period, or estimate effective operating hours without counting idle time twice.
