Home Well Pump Energy Cost Calculator
Well pumps can be a hidden chunk of your electric bill. Enter your pump's horsepower, how many minutes per day it typically runs, and your electricity rate to estimate what it's costing you.
About this calculator
Estimate the monthly and yearly electricity cost of running your well water pump based on horsepower, run time, and your local electricity rate.
Frequently Asked Questions
How much electricity does a well pump use?
A typical 1 HP well pump draws around 0.75-1 kW depending on motor efficiency, so running 30-60 minutes per day usually costs a few dollars per month, more for larger pumps or high-demand households.
Why does motor efficiency matter?
Not all input power gets converted to pumping work — inefficiency shows up as heat, so lower efficiency motors draw more electricity for the same output.
How can I reduce well pump energy costs?
Fix leaks that cause the pump to cycle frequently, ensure correct pressure tank sizing, and consider a variable-speed pump for large households.
