Formula explanation
How this calculator works
Core formula
daily kWh = (watts / 1000) * hours; cost = kWh * rateThe calculator converts appliance wattage into daily energy use, then applies your electricity rate to estimate recurring cost over longer time periods.
- The model assumes the appliance draws the same power whenever it is on.
- Bills can differ if tariffs change by time of day or include fixed charges.
