Pool Pump Runtime & Energy Calculator
Estimate pump turnover time, daily runtime, and energy cost — and compare single-speed vs variable-speed savings.
PUMP CALC
Turnover & Daily Runtime
Not sure? Use the pool volume calculator.
From your pump curve; many residential pumps move ~40–80 GPM.
Turnover & Runtime
-- hours
One full turnover
Typical daily runtime (1–2 turnovers)
--
Rule of thumb: aim to circulate your water once or twice a day, but you don't
strictly need a full turnover — run the pump enough to keep the water clear and your chlorine holding.
Energy Cost
From the motor label or a plug-in meter. Rough guide: single-speed ~1,500–2,000 W; a variable-speed pump runs far less on low speed (~100–300 W) than on high.

Why variable-speed wins: energy use rises steeply with speed, so a variable-speed
pump running slowly for more hours usually moves the same water for a fraction of the power. These are
estimates — your real numbers depend on your pump, speeds, and local rate.
