Cost of Owning a Pool Calculator

This calculator works out the ongoing cost of owning a swimming pool in New Zealand, the figure that often surprises people far more than the build price. A pool is not a one-off purchase; it is a year-round running cost, and understanding that cost before you build, or when you are buying a home with a pool, helps you budget honestly and avoid resentment when the power bill arrives. The biggest cost for most pools is electricity, to run the filtration pump for several hours a day and, if you have it, to heat the water with a heat pump or element, which can add hundreds of dollars over a swimming season. Then there are chemicals to keep the water safe and balanced, water to top up evaporation and backwashing, regular servicing or your own time, and often a small increase in home and contents insurance. You enter your estimated yearly figures for power, chemicals, water, maintenance and insurance, and the calculator adds them into a total annual cost and breaks it down to a monthly and weekly figure so the commitment is clear. Use it to budget for a pool you own, to factor running costs into a house purchase, or to see how choices like a pool cover, a timer on the pump, or switching off heating in winter could cut the bill. A well-fitted pool cover, in particular, reduces evaporation, heat loss and chemical use, and usually pays for itself. The figures are your own estimates, so the more accurate your inputs the more useful the result; treat it as a planning guide.

A pool cover cuts power, water and chemical use and usually pays for itself. Heating is the biggest variable. An estimate from your figures.
