Electricity cost calculator allows consumers to estimate annual electricity cost in a straightforward way. Paying those monthly bills it's normal to ask: how much does electricity cost? Plotting down a few values in this electricity calculator will save you some time and give you a precise answer to the question, for example when you consider switching to LED bulbs. You might also want to see electricity cost - single usage calculator.
How does the electricity cost calculator work?
It's rather simple. If you know the value for power consumption, energy price and usage time, the calculator will automatically display how much power you consume per day and generate the exact annual price for electricity. You can change units at will (for example change days to months or watts to kilowatts).
How much does electricity cost?
Let's suppose the following for our utility.
- power consumption: You consume
1000 wattsof electricity
- energy price is
- usage time is
If we know that, then our electric bill estimator will tell us that we'll consume
10 kWh / day and the annual cost will be
Let's do the math on our own:
power consumption * usage time = power consumed. So we'll consume
10000 watt hoursor
10 kilowatt hoursof power every day.
- The electricity cost is
cost = power consumed * energy price. It's easy:
10 kWh per day * €0.28/kWh = €2.8 per day.
- For the annual cost, simply multiply the daily one * the number of days in a year.
€2.8 per day * 365.25 days = €1022.70. Same as the electricity cost calculator told us (surprised?).
