Calculate 3D printer electricity cost, energy use, hourly cost, and monthly cost with our free 3D Printer Electricity Cost Calculator.
Want to know how much electricity your 3D printer uses? Our 3D Printer Electricity Cost Calculator makes it simple.
You can enter your printer's average power, print time, and electricity rate. The calculator then estimates energy use and running cost. You can also enter measured energy in kWh for a more direct result.
This free 3D printer calculator helps you estimate the 3D printing electricity cost, cost per hour, and monthly electricity cost. It can help home users, makers, students, and 3D printing businesses plan their printing costs.
The main 3D printer electricity cost formula is:
Electricity Used (kWh) = (Power (W) × Print Time (hours)) ÷ 1000
Then:
Electricity Cost = Electricity Used (kWh) × Electricity Rate per kWh
So the direct formula is:
3D Printer Electricity Cost = (Power × Print Time × Electricity Rate) ÷ 1000
For example, a 120 W printer running for 8 hours uses:
(120 × 8) ÷ 1000 = 0.96 kWh
If electricity costs $12 per kWh:
0.96 × 12 = $11.52
Therefore, the 3D printer electricity cost is $11.52 for that print.
You can also calculate the 3D printer electricity cost per hour with:
Cost per Hour = Total Electricity Cost ÷ Print Time
Or:
Cost per Hour = (Power × Electricity Rate) ÷ 1000
With 120 W power and a $12/kWh rate:
(120 × 12) ÷ 1000 = $1.44 per hour
For regular printing, use:
Monthly Cost = Cost per Hour × Hours per Day × Days
This gives a quick estimate of the electricity cost of running a 3D printer each month.
Choose the calculation mode. Select Power Mode when you know the printer's average power draw. Select Measured Energy Mode when you know the actual energy used in kWh.
Enter the printer power. Enter the average power draw in watts, such as 120 W.
Enter print time. Enter how long the 3D printer runs in hours.
Enter your electricity rate. Add your local electricity price per kWh. This works for users searching for a 3D printer electricity cost calculator UK as well as users in other countries.
Check the results. The calculator shows energy use and electricity cost. It can also show hourly and monthly costs when the monthly option is enabled.
Suppose your 3D printer uses an average of 120 W. Your print takes 8 hours. Your electricity rate is $12 per kWh.
First, calculate energy:
Energy = (120 × 8) ÷ 1000
Energy = 0.96 kWh
Next, calculate the electricity cost:
Cost = 0.96 × 12
Cost = $11.52
The 3D printing electricity cost is therefore $11.52.
The hourly cost is:
$11.52 ÷ 8 = $1.44 per hour
If the printer runs 8 hours per day for 30 days:
Monthly Cost = $1.44 × 8 × 30
Monthly Cost = $345.60
For measured energy, simply enter the actual kWh used. The calculator multiplies that energy by your electricity rate. It also calculates the implied average printer power.
Our 3D Printer Electricity Cost Calculator gives you a quick way to estimate the electricity cost of 3D printing. It supports both average power and measured energy. You can also estimate 3D printer electricity cost per hour and monthly running costs.
Remember that actual power use can change during a print. Heater use, bed temperature, nozzle temperature, print settings, and printer design can all affect real energy use. For the best estimate, use measured kWh when available.
It depends on the printer's average power draw and print time. Use the calculator to estimate the actual kWh consumed.
Multiply power in watts by print time in hours, divide by 1,000, then multiply by your electricity rate per kWh.
Cost per hour depends on average power and your electricity rate. The formula is (Power × Rate) ÷ 1000.
Yes. Enter your UK electricity rate in the rate field and use the same kWh calculation.
It calculates the electricity portion of your 3D print cost. Material, labor, machine depreciation, maintenance, and other business costs are separate.
Yes. It can be used to estimate electricity consumption and electricity cost without manually doing the calculations.
