Let’s do the math by hand:

1. power consumption * usage time = power consumed. So we’ll consume 10000 watt hours or 10 kilowatt hours of power every day.
2. The electricity cost is cost = power consumed * energy price.
3. For the annual cost, simply multiply the daily one * the number of days in a year.

How do you calculate cost per kWh?

The kilowatt-hour rate is the price of power supplied by your electric provider. To calculate your kilowatt-hour rate, divide your total power bill, minus any taxes, by your total power consumption.

How do you convert kWh to dollars?

Find the kilowatt-hours:

1. kWh = P_(W) × T_(h/day) ÷ 1,000_(W) kWh = 400 W × 4 hrs ÷ 1,000. kWh = 1.6 kWh.
2. Price = Electricity_(kWh) × Cost_(cost/kWh) Price = 1.6 kWh × $.12. Price = $.19 per day.
3. Monthly Price = $.19 per day × 30. Monthly Price = $5.70.
