🔌 What Do You Need to Know?
To calculate your electricity bill, you need 3 simple things:
- How much power each appliance uses (in watts or kilowatts)
- How long you use each one per day
- Your electricity rate per kilowatt-hour (kWh)
⚡ Electricity Bill Formula
Here’s the basic formula:
Electricity Cost = (Wattage × Hours Used × Days) ÷ 1000 × Cost per kWh
That’s a fancy way of saying:
“Take the power usage, multiply by time, convert to kilowatt-hours, and multiply by your rate.”
⚙️ Example
Let’s say your fridge uses 150 watts, runs 24 hours a day, and electricity costs $0.13 per kWh.
Daily use:
150 W × 24 h = 3,600 Wh = 3.6 kWh/day
Monthly cost:
3.6 × 30 days × $0.13 = $14.04/month
