Electricity Cost Calculator

By Mateusz Mucha.

The electricity cost calculator allows consumers to estimate their annual electricity cost in a straightforward way. After you pay your monthly bills for a while it's normal to ask: how much does electricity cost? By simply entering a few values in this electricity calculator will save yourself time and effort as well as getting a precise answer to the question. It well help you calculate, for example, the money you would save if you switched to LED bulbs. You might also want to check out our 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 also change the units at will (for example change days to months or watts to kilowatts).

How much does electricity cost?

Let's say that our utility bill comes to the following:

  1. power consumption: You consume 1000 watts of electricity
  2. energy price is €0.28/kWh
  3. usage time is 10 hours/day

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 € 1022.70.

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. It's easy: 10 kWh per day * €0.28/kWh = €2.8 per day.
  3. 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?).

Now that you know how much electricity costs, you might be interested in saving money with the price per quantity and the discount calculators.
