Calculate the daily, monthly, and yearly electricity cost of any appliance from its wattage and your kWh price.
How it works
kWh / day = (watts × hours) / 1000. Cost = kWh × price per kWh. Monthly ≈ × 30, yearly ≈ × 365.
Example
1,500 W heater, 4 h/day at $0.18/kWh → $1.08/day, $32.40/month, $394.20/year.
