THE MATH
Plain wattage × time × rate.
Estimated kWh = watts ÷ 1,000 × hours used. Multiply by your entered electricity rate to estimate cost. Monthly assumes 30 days; yearly assumes 365. Real devices cycle, idle, and change load, so rated watts and assumed hours can overstate or understate actual use. This is an estimate, not a bill prediction.
