Instantly estimate your pool’s total water volume and how long it will take to fill using a standard garden hose. Accurate calculations help you properly balance chemicals and size equipment correctly.
Use our easy pool volume calculator to estimate total gallons for rectangle, freeform, kidney, and oval pools.
Estimate the gallons in your pool, how long it will take to fill, and what it will cost.
Results are estimates based on average pool geometry and Phoenix-area water rates (~$3 per 1,000 gallons including base service and sewer impact). Actual volume and cost can vary with pool shape, step features, tanning ledges, your municipality, and your usage tier.
Accurate gallon calculations help you balance pool chemicals correctly, choose the right pump or heater size, estimate fill times, and maintain healthier water.
