Electricity Cost – Single Usage Calculator

This electricity cost – single usage calculator tells you how much it costs to run an electrical device for a certain amount of time. It's often the topic of conversation and most of the time we have no clue how much it really costs to run our electric appliances.

Our tool can serve great as an electricity bill calculator – just enter the power consumption of your device, the usage time, and actual energy prices per kWh, and you will find out how much electricity costs. Are you horrified by the result? Don't worry, here are some protips how to lower your electric bill! 💰

If you're wondering how much electricity costs, all you need to know is the power consumption of your electrical device, how long it runs, and the actual energy prices offered by your supplier. The calculation runs in two steps. First, multiply power consumption of your device by usage time to find how much energy your device consumed during work:

power consumption × usage time = energy consumed

Be mindful of the units if you're doing the calculations by hand, and apply the corresponding conversion factors. If you are using our calculator, you can ignore this warning because all the unit conversion required is done for you.

Then, check the electricity cost per kWh from your local energy supplier and multiply it by the amount of energy consumed:

cost = energy consumed × energy price

Let's give a hypothetical example: you used your 700-watt vacuum cleaner for half an hour. It's 700 Watts × 30 min = 350 Wh or 0.35 kWh. With the electricity prices of $0.14 per kWh, the total cost is 0.35 kWh × $0.14/kWh. Thus, a single vacuuming of your apartment costs you $0.05 💵

If you're interested in the recurring usage of utilities such as how much it costs to charge your Tesla, try the electricity cost calculator.

Our electricity cost – single usage calculator needs just a few steps to tell you how much electricity costs once the selected device is running. For example, you might be wondering how much it costs to boil 2 liters (a little more than 7 cups) of water in an electric kettle. To calculate this:

1. Determine power consumption of your device in watts. In our example, we boil water in a 2000 watt kettle.

2. You know it takes it 6 minutes to do it, so enter usage time below.

3. This calculator will do the calculation for you and return you a value of 0.2 kWh of energy consumed during boiling water.

4. Check the actual electricity cost per kWh and enter a value. With an average cost of $0.13 per kWh, we arrive at the value of 3 cents per single use.

Of course, high electricity prices can cause your costs to skyrocket, so we've put together some proven ways how to lower your electric bill:

1. Get a home energy audit.

2. Switch to dimmer switches.

3. Keep your fridge and freezer closed.

4. Keep the air circulating in your home with ceiling fans.

5. Eliminate phantom loads from televisions, computers, kitchen appliances, etc.

6. Switch to LED light bulbs.

7. Shade your home with trees, curtains, and blinds.

8. Use cool water for laundry.

9. Wash the laundry in full loads or use "eco" mode.

10. Install a water heater timer.

11. Check if your home is properly insulated.
