How this cost is calculated
The formula is kWh = watts ÷ 1000 × hours, then cost = kWh × your rate per kWh. Standing charges and tiered or time-of-use pricing are billed separately by your supplier, so treat these numbers as the marginal cost of running this appliance rather than a full bill.

Frequently asked questions
How much does a pool pump cost to run per day?
A 1,500W single-speed pump running 8 hours uses 12 kWh, about $1.92 a day at $0.16/kWh.
Do variable-speed pumps really save 70%?
Often yes. Halving pump speed cuts power draw to roughly one eighth, so longer, slower filtration uses far less energy.
How long should a pool pump run each day?
Most pools need one full turnover, typically 6-8 hours for a variable-speed pump in summer.
