In 2021, an average US household spent 886 kWh per month, according to EIA. If you know how many kilowatt-hours (kWh) of electricity you are spending, you can easily calculate how much it will cost (in US dollars).
To help you out with this calculation, we have designed a simple kilowatt-hour calculator (kWh cost calculator) that translates used kWh to USD ($). On top of that, you will also find a chart of kWh to US dollars for $0.10/kWh, $0.15/kWh, $0.20/kWh, and $0.30/kWh electricity prices.
Calculating your electricity bill from spent kWh is fairly easy. All you need to do is to multiply the used kWh by the price of electricity (per kWh). Here is the kilowatt-hour formula that does just that:
Electricity Bill ($) = Number Of kWh Used × Price Of Electricity (Per kWh)
Quick example: Let’s say you use these 886 kWh per month and you have an about average electricity rate of $0.15/kWh in your area. Here is how you can calculate how much does electricity per month costs:
Electricity Bill ($) = 886 kWh × $0.15/kWh = $132.90/Month
As you can see, the electricity bill depends only on two factors:
- Number of kWh used. The more kWh of electricity you spend, the bigger electricity bill you will have.
- Price of electricity per kWh. Higher electricity rates will result in higher electricity bills.
For a bit of help figuring out kWh used, you can use this watts to kWh calculator.
Using this cost per kilowatt-hour calculator, you can figure out how much you will pay for electricity. Below the calculator, we also present a chart with 1-10000 kWh converted to $ at very low, low, average, high, and very high electricity rates:
kWh Calculator
Just insert the kWh spend and the electricity rate in your area (here are average electricity prices state-by-state by the US Bureau Of Labor Statistics to help you out). The calculator will automatically calculate how much you will pay for electricity:
Here is how this calculator works:
Let’s say you spent 500 kWh of electricity and the electricity rate in your area is $0.15/kWh. Just slide the 1st slider to ‘500’ and the 2nd slider to ‘0.15’ and you get the result: 500 kWh of electricity at $0.15/kWh electricity rates will cost $75.00.
Now, this is just one example. We will look at how much you will pay for 1-10000 kWh at:
- Low electricity price: $0.10/kWh.
- Average electricity price: $0.15/kWh.
- High electricity price: $0.20/kWh.
- Very high electricity price: $0.30/kWh.

As you can see from the chart, 1 kWh can cost anywhere from $0.10 to $0.30 (in some states, you may pay even less than $0.10, and in California, the electricity prices per kWh can cross $0.30/kWh).
With the kilowatt-hour calculator and this chart, you can simply figure out how much will any amount of electricity (kWh) cost.
