Single-Speed or Variable-Speed: Which Pump Fits Your Pool?

Answer 6 quick questions about your budget, usage and electricity rates, and we'll point you to the pump type that fits -- plus the calculators to size and run it.

Pool pumps mostly come down to two choices now: a single-speed pump that runs at one fixed, high speed whenever it's on, or a variable-speed pump that can run at lower speeds for most of the day and ramp up only when needed. Variable-speed pumps cost more upfront but use dramatically less electricity over a season; single-speed pumps cost less to buy but run harder and can cost more to operate, especially where electricity rates are high.

This quiz weighs your budget, how the pool actually gets used, your electricity rates, noise tolerance, and how long you plan to keep the pool, then tells you which pump type fits -- along with the sizing and running-cost calculators to plan around it.

How the finder decides

It asks six questions covering your budget, how the pool is used, your electricity rates, noise tolerance and how long you plan to keep the pool, then points you to a single-speed or a variable-speed pump. A variable-speed pump costs more up front but can run at lower speeds for most of the day, which uses much less electricity over a season.

Next steps

The pump size calculator works out the flow in gallons per minute that your pool needs for a target turnover time, whichever type you pick. Use the pump maker’s data to check a specific model against that flow.
