Appliance Electricity Cost Calculator
Pick an appliance and see its hourly, daily, monthly and yearly running cost.
How it works
The calculator converts the appliance’s power draw from watts to kilowatts (divide by 1,000), multiplies by the hours it runs per day and your tariff to get a daily cost, then scales up to a monthly and yearly figure based on daily use. The wattage presets are typical estimates — check the appliance’s rating label for its actual draw.
cost = watts ÷ 1000 × hours × tariff ($/kWh)
Worked example
A 2,000 W portable heater running 3 hours a day at $0.30/kWh:
- Kilowatts
- 2,000 W ÷ 1,000 = 2.0 kW
- Daily energy
- 2.0 × 3 = 6 kWh
- Per day
- 6 × $0.30 = $1.80
- Per year
- $1.80 × 365 ≈ $657
Frequently asked questions
A typical dryer draws around 2500W. Run for an hour a day at $0.30/kWh, that's about $0.75/hour, or roughly $23/month if used daily. Select 'Clothes Dryer' above and adjust the wattage and hours to match your machine.
