Calculate your pool pump electricity cost based on horsepower, motor efficiency, daily runtime, and electricity rate. See daily, monthly, and annual operating costs.
Enter your pump horsepower, motor efficiency (typically 80–90%), daily runtime hours, and your electricity rate per kWh. The calculator converts HP to kilowatts accounting for motor losses.
The formula: Power (kW) = (HP × 746) ÷ (efficiency% ÷ 100) ÷ 1000. Daily cost = kW × runtime hours × rate. This gives you accurate daily, monthly, and annual operating costs.
Use this calculator to compare the cost of running your current pump versus a more efficient variable speed model. Even a modest reduction in HP or efficiency improvement can save hundreds per year.
