About the Electricity Cost Calculator for Appliances
Estimate what an appliance costs to run from its power rating, how long you use it and your electricity rate per unit (kWh). A 1,500 W heater used for 4 hours at ₹8 per unit costs ₹48.
Use it to compare appliances and to see which ones drive your power bill.
Running cost
Cost = watts ÷ 1000 × hours × rate per kWh
Things to keep in mind
- Your electricity rate per unit is on your bill; slab rates may change the rate as usage increases.
- The power rating is on the appliance label, in watts. Air conditioners and heaters cycle on and off, so real use is often lower.
- Standby power adds a small amount for devices left plugged in.
