See how much water and heating cost a cover saves your pool each year — and how quickly it pays for itself.
Most of a pool's water and heat is lost from the open surface to evaporation. A cover stops roughly 90–95% of evaporation, saving both the water itself and the energy that would have reheated it. The U.S. Department of Energy estimates a cover can cut total pool heat loss by around half, sometimes more. Savings scale with surface area, so larger pools benefit most. Enter your surface area, local water price, and monthly heating cost to see the annual saving and payback time.
