What is a kWh?
A **Kilowatt-hour (kWh)** represents the amount of energy consumed by a 1,000-watt appliance running continuously for 1 hour.
For example, leaving a 1,500W space heater running for 10 hours utilizes 15 kWh of energy (1,500 × 10 = 15,000 Watts).

Utility fees represent a significant percentage of household budgets. If your electricity bills fluctuate, you may want to analyze which appliances draw the most power. The Electricity Bill Calculator makes tracking appliance electricity rates simple.
How to Calculate Electricity Costs
To find out the running cost of a specific appliance, apply this formula:
- Find the appliance wattage (W) written on its technical tag.
- Convert Watts to Kilowatts: Watts ÷ 1,000 = Kilowatts (kW).
- Multiply by running hours: kW × Hours per Day = Daily kWh Usage.
- Multiply by utility price: Daily kWh × Cost per kWh = Daily Operating Cost.
- Multiply by cycle days (e.g. 30 days) to find the monthly bill footprint.
How to Work Out Electricity Costs
Suppose you run a 1,200-watt air conditioner for 6 hours per day, and your power company charges you $0.15 per kWh:
- Step 1: Convert to kW: 1,200W ÷ 1,000 = 1.2 kW
- Step 2: Find daily kWh: 1.2 kW × 6 hours = 7.2 kWh per day
- Step 3: Find daily cost: 7.2 kWh × $0.15/kWh = $1.08 per day
- Step 4: Find monthly cost: $1.08 × 30 days = $32.40 per month
