Pool Ownership Planning Calculator

Estimate pump runtime cost, total ownership cost, cover payback, and repair reserve planning from one public worksheet. Use the related tools when heater, evaporation, or refill planning is the better baseline.

Pump energy Heater heat-up Evaporation Water exchange

Compare the current and alternate schedules, then check cover payback, pump upgrade savings, heater reserve, and repair set-asides before you buy or replace anything.

Pump schedule

Enter a current schedule first. Fill the optional alternate schedule to compare a second speed or runtime. The horsepower path is only a proxy for load, not a measured watt reading.

Pump runtime planning

Use this section to compare the current and alternate schedules before you change speed or runtime. The monthly delta is the savings baseline for a pump upgrade or variable-speed retrofit.

Current monthly cost: ‏64.80 US$
Current annual cost: ‏777.60 US$
Alternate monthly cost: ‏30.24 US$
Monthly delta: ‏34.56 US$ less than current

Total ownership cost

This rolls the pump schedule, monthly operating allowance, and repair reserve together. Use it when you want the yearly ownership number that includes pump, heater, cover, and other replacements.

Current monthly total: ‏221.47 US$
Current annual total: ‏2,657.60 US$
Alternate monthly total: ‏186.91 US$
Monthly delta: ‏34.56 US$ less than current

Cover ROI

Compare your cover purchase against the annual savings, refill savings, and upkeep you expect from it. Use this when a cover changes evaporation, heater load, or the amount of water you have to replace.

Annual gross savings: ‏420.00 US$
Annual net savings: ‏360.00 US$
Simple payback: 4.2 years
ROI: 24.0%

Repair reserve planning

Set aside money for replacements before the next part failure becomes a surprise. This keeps pump, heater, cover, and other replacement costs from turning into a one-off hit.

Annual reserve: ‏1,400.00 US$
Monthly set-aside: ‏116.67 US$
Pump reserve: ‏300.00 US$
Heater reserve: ‏500.00 US$
Cover reserve: ‏300.00 US$
Other reserve: ‏300.00 US$
