Use the free Appliance Electricity Cost Estimator below — enter your values and get instant results, right in your browser. Monthly kWh = appliance watts × hours per day × days ÷ 1000. Monthly cost = kWh × tariff (Rs/kWh). Example: 1.5-ton inverter AC (1800W) × 8h × 30 days ÷ 1000 = 432 kWh × Rs 45 = Rs 19,440 per month.

How to use the Appliance Electricity Cost Estimator

That shocking electricity bill is just the sum of every appliance running every day — and the AC is usually the biggest culprit.

  1. Select the appliance from the dropdown — start with the AC, the usual bill-killer.
  2. Enter how many hours per day it actually runs (an inverter AC cycles, so use realistic compressor hours).
  3. Enter the days per month it runs and your tariff in Rs per unit from your bill.
  4. Click Calculate to see the monthly kWh and the rupee cost for that one appliance.

Formula

Monthly kWh = appliance watts × hours per day × days ÷ 1000. Monthly cost = kWh × tariff (Rs/kWh). Example: 1.5-ton inverter AC (1800W) × 8h × 30 days ÷ 1000 = 432 kWh × Rs 45 = Rs 19,440 per month.

Worked example

A 1.5-ton inverter AC (1800W) runs 8 hours daily for 30 days at Rs 45/unit: 1800 × 8 × 30 ÷ 1000 = 432 kWh, costing Rs 19,440 — often half the summer bill. A fridge (150W) running 24 hours uses 108 kWh (Rs 4,860), and an iron (1000W) used 1 hour daily costs Rs 1,350.

Frequently asked questions

An inverter 1.5-ton AC (1800W) running 8 hours daily uses about 432 units per month, costing roughly Rs 19,440 at Rs 45/unit. A non-inverter model (2200W) uses about 528 units — Rs 23,760.

The air conditioner, by far — one AC can exceed all other appliances combined. After the AC come the electric water heater/geyser, iron, and water motor. LED bulbs and fans are cheap by comparison.

Yes — typically 30–40% less than a non-inverter of the same tonnage, because the compressor slows down instead of switching fully on and off. At 8 hours daily use, the savings can exceed Rs 4,000 per month in summer.
