What This Tool Does

How to Use

  1. Enter your appliance's power rating in watts (look for a label or estimate using similar appliances as reference).
  2. Input your average usage in hours per day. Decimals supported (e.g., 1.5 for 90 minutes).
  3. Specify how many days/month you use it (e.g. daily = 30; weekends = 8).
  4. Enter your local electricity rate per kilowatt-hour ($/kWh) - find this on your utility bill or use a country/state average.
  5. Click "Calculate" to see your power usage and cost breakdown.
  6. Copy or share the results as needed.

Example Calculation

Example: You have a 1500W space heater, run for 4 hours a day, used 30 days/month, at $0.16/kWh.
The result is:
  • Electricity used per day: 6.00 kWh
  • Daily cost: $0.96
  • Monthly cost: $28.80
  • Annual cost: $350.40

FAQ: Appliance Energy Cost Calculator

Can I use this tool for any country?
Yes. The tool works worldwide. Just enter your local electricity rate in your currency per kWh – adjust the currency symbol in your brain or results!
What if my appliance says "Amps" instead of "Watts"?
Multiply Amps × Volts to get Watts. In the U.S., most home appliances run at 120 volts; in Europe, 220–240 volts is common.
How do I find my electricity rate?
Look for "rate per kWh" on your utility bill, usually as $ per kWh or similar. Or search your average rate by city/country.
Can this help reduce my electricity bill?
Yes! Use it to spot high-usage appliances, then reduce usage, upgrade to efficient models, or change habits to save money.
