How the calculation works
Energy
Energy in kWh = power in watts ÷ 1,000 × hours used.
Cost
Electricity cost = energy in kWh × electricity rate per kWh.
How to use this calculator
- 1Enter appliance wattage.
- 2Enter average hours used per day.
- 3Enter the number of days and electricity tariff per kWh.
- 4Review energy use and estimated daily, monthly, yearly, and selected-period cost.
Understanding the result
The selected-period result represents usage charges based only on the entered energy rate.
Daily, 30-day, and annual estimates assume the same daily usage pattern continues.
Important limitations
- Actual bills may include taxes, fixed fees, slab tariffs, demand charges, minimum charges, or time-of-use pricing.
- Rated appliance wattage may differ from real operating consumption.
Frequently asked questions
How do I convert watts to kWh?
Divide watts by 1,000 to get kilowatts, then multiply by operating hours.
Does this calculate my complete electricity bill?
No. It estimates usage cost from the entered per-kWh rate.
Can I calculate yearly appliance cost?
Yes. The calculator displays a 365-day estimate.
