How to use the pool maintenance cost calculator
Enter what your pool actually costs you, and the calculator above turns it into a yearly total. Every field uses your own numbers, so the result reflects your climate, equipment and habits rather than a national average.
- Months the pool is open. Use 12 for year-round pools.
- Chemical spend per month. Your typical monthly spend on chlorine, acid, stabilizer and balancers.
- Pump power. The watts the pump draws at the speed you normally run. Single-speed pumps list it on the motor label; variable-speed pumps usually show it on the controller or app.
- Pump hours per day. How long the pump runs on a typical day.
- Electricity price. The rate per kWh from your utility bill.
- Pool service per month. Leave at 0 if you do the work yourself.
- Yearly repair reserve. Money set aside for filters, parts and future big jobs such as a new liner or replaster.

How the calculator works
The calculator adds four parts: pump electricity, chemicals, service and your repair reserve. It assumes 30.4 days per month open.
- Pump kWh = (watts ÷ 1,000) × hours per day × (months × 30.4)
- Electricity = kWh × price per kWh
- Chemicals = monthly chemical spend × months
- Service = monthly service fee × months
- Yearly total = electricity + chemicals + service + repair reserve
Results are rounded to the nearest $100, because the inputs are estimates. The formulas are also documented on our methodology page.
Worked example. A pool open 6 months, with a 1,500 W pump running 8 hours a day at $0.17 per kWh, $50 a month in chemicals, no service and a $300 reserve:
- Days open: 6 × 30.4 = 182.4
- Pump energy: 1.5 kW × 8 h × 182.4 days = 2,188.8 kWh
- Electricity: 2,188.8 × $0.17 = $372.10
- Chemicals: $50 × 6 = $300
- Total: $372.10 + $300 + $0 + $300 = $972.10, shown as about $1,000 a year
Swap in a variable-speed pump drawing 300 W for 12 hours a day and pump energy drops to 656.6 kWh, or about $112 for the season. Add a $120 monthly service and the total rises by $720.
What does pool maintenance cost per year?
HomeGuide puts yearly pool maintenance at $960 to $1,800, with most owners spending about $1,400, and all-in ownership at $3,000 to $6,000 a year. The all-in figure adds utilities, repairs and opening and closing to routine care.
| Cost item (HomeGuide) | Yearly range |
|---|---|
| Maintenance (cleaning and service) | $960–$1,800 |
| Chemicals | $175–$750 |
| Electricity | $800–$1,200 |
| Water | $50–$250 |
| Repairs | $400–$1,000+ |
| Opening and closing | $650–$1,000 |
| All-in ownership | $3,000–$6,000 |
Electricity is where the guides disagree most. HomeGuide lists $800 to $1,200 a year, while HomeAdvisor says pump electricity can reach $300 a year and that variable-speed pumps use less. Pump size, run time, season length and local rates can explain that gap, which is why the calculator asks for your own watts and rate instead of using a fixed figure.
Chemical cost depends heavily on pool type. HomeGuide estimates about $175 a year for fiberglass, $400 for vinyl and $750 for concrete.
How much does pool service cost?
Professional pool service typically costs $80 to $150 a month for weekly or bi-weekly cleaning, according to HomeGuide. Prices vary with what the visit includes and how often the technician comes.
| Source | Service level | Price |
|---|---|---|
| HomeGuide | Basic monthly care | $30–$95 per month |
| HomeGuide | Weekly or bi-weekly cleaning | $80–$150 per month |
| HomeAdvisor | Cleaning plus water testing | $80–$150 per month |
| HomeAdvisor | Single visit | $116–$357 (avg $236) |
| Fixr | Monthly maintenance on annual contract | $30–$90 per month |
| Fixr | Weekly service | $20–$50 per week ($1,040–$2,600 per year) |
| This Old House | Monthly maintenance | $90–$270 per month |
When you compare services, ask whether chemicals are included or billed separately, how often water is tested, and whether filter cleaning and equipment checks are part of the visit.
What pool costs are easy to forget?
Heating, salt cell replacement and water top-ups are the costs most owners leave out of their first budget. Add them to the repair reserve or chemical fields in the calculator above.
- Heating. HomeGuide says a gas heater costs $200 to $500 or more per month to run, and a heat pump $50 to $150 per month. Heaters last 10 to 12 years.
- Salt cell replacement. HomeGuide puts a new cell at $500 to $800 every three to six years; HomeAdvisor says about $800 every three to seven years.
- Water top-ups. HomeGuide says pools lose about 1/4 inch a day to evaporation and splashing, and HomeAdvisor puts top-up water at about $0.004 per gallon.
- Opening and closing. $650 to $1,000 a year if you hire it out, per HomeGuide.
- Big repairs. Liners and plaster eventually need replacing; a steady yearly reserve keeps those from becoming a surprise.
Top-up example. A 16 × 32 ft pool has 512 sq ft of surface. Losing 1/4 inch a day is 512 × (0.25 ÷ 12) = 10.7 cubic feet, or about 80 gallons a day. Over a 182-day season that is roughly 14,500 gallons, or about $58 at $0.004 per gallon. Hot, dry and windy climates lose more.
How can I lower pool maintenance costs?
The biggest savings come from running the pump efficiently, covering the pool, and dosing chemicals accurately instead of guessing.
Cover the pool. The EPA’s WaterSense pool water efficiency guide says pool covers are the most effective way to reduce evaporation: solid covers cut evaporation by more than 90% and save 50% to 70% of heating costs for heated pools. Less evaporation also means less water and fewer chemicals to replace.
Run the pump smarter. A variable-speed pump running longer at low speed usually draws far less power than a single-speed pump. Enter its real watts at your usual speed to see the difference in the calculator above.
Dose by the numbers. Know your pool’s exact gallons from the pool volume calculator, test before you add anything, and add only what the test calls for. Overdosing wastes money and can push other levels out of range.
Buy by strength, not by jug. Liquid chlorine and other products come in different concentrations. Compare price per unit of active ingredient, not price per container.
Handle chemicals safely. Never mix pool chemicals, always add chemicals to water rather than water to chemicals, keep acid and chlorine apart, and wear gloves and eye protection. Follow the product label.
Upkeep is only part of the picture. To see what the pool itself costs to build, including fence, decking and heating, use the inground pool cost calculator.
