Estimate the running cost of an appliance from its wattage, usage hours and electricity rate generally.
Energy used = watts × hours ÷ 1,000 (kWh), then monthly cost = daily kWh × days × the electricity rate. Small wattage differences compound fast on devices used daily.
Cost
Cost = watts × hours ÷ 1000 × rate
Estimate — actual draw varies by mode and usage.
No — enter the rate from your latest utility bill for accuracy.
Rates are approximate reference values. Local rates, exemptions and rules can differ, so treat the output as a planning figure only.
