Enter your pump's wattage, how many hours a day it runs, and your electricity rate to see what it's really costing you. Not sure on run time? Check the pool pump run time calculator first.
Estimate only — a variable-speed pump can cut this substantially versus a single-speed pump.
We divide wattage by 1,000 to get kilowatts, multiply by hours run per day for daily kWh, then by 30 for a monthly figure and by your rate per kWh for monthly cost. Yearly cost multiplies the monthly figure by 12.
Pool pumps are often one of the largest single electricity draws in a home because single-speed models run at their full 1,500-2,500W output for hours a day regardless of actual filtering needs. A variable-speed pump can run longer at a much lower wattage and still hit the same turnover, which is why switching often cuts pump electricity cost by 50% or more.
A typical single-speed pump running 8 hours a day can cost $40-$80 a month depending on wattage and your electricity rate — enter your pump's specs above for a precise figure.
Often yes — running longer at a lower speed uses dramatically less electricity than a single-speed pump's fixed high draw, and many utilities offer rebates that offset the higher upfront cost.
