Is a pool expensive to maintain? The ratio answer

Pool maintenance is the yearly cost of keeping the water safe and the equipment running: chemicals, pump electricity, water top-ups, small repairs and, if you pay for it, a technician’s time. Measured against the cost of the pool itself, it is modest. Doing it yourself costs about $1,200–$2,500 a year for a 50,000-litre pool on one running-cost guide, updated in August 2026. The most-read national cost guide, updated October 2026, puts a typical fibreglass pool at $65,000, so DIY maintenance is 1.8–3.8% of the build price a year.

The percentage moves with the price of the pool more than with its type. The same $1,200–$2,500 is 2.7–5.6% of a $45,000 plunge pool and 1.1–2.3% of a $110,000 concrete pool, because a smaller pool does not cut the per-visit price of a service, and many running costs do not fall in step with the pool’s size.

The maintenance-to-build ratio: a pool you look after yourself costs about 2–4% of its build price a year to maintain, and a fortnightly service roughly doubles that to 4–8%. Whether that is expensive depends on the next two sections: who does the work, and what the figure leaves out.

How much does a pool cost to maintain each year if I pay someone?

A pool service is priced by the visit, and the visit price is mostly labour. One national pool-care franchise publishes $77–$120 for a service call or a monthly program and $65–$95 a visit on a regular program, with chemicals extra. Add that to the DIY running cost and the year looks like this:

• DIY plus a monthly visit: $2,124–$3,940 a year, 3.3–6.1% of a $65,000 pool.
• Fortnightly service: $2,890–$4,970 a year, 4.4–7.6%, or $57.80–$99.40 per kilolitre.
• Weekly service: $4,580–$7,440 a year, 7.0–11.4%.

The running-cost guide itself prices a visit higher, at $100–$250, and says a monthly visit adds $1,200–$3,000 a year. Use the franchise figures as the lower bound and the guide’s as the upper. Visit-by-visit prices, what a visit includes and the do-it-yourself crossover are on how much a pool service costs; this page does not repeat them.

The labour rule: a fortnightly service’s visits alone cost $1,690–$2,470 a year, about as much again as running the pool yourself ($1,200–$2,500).

Why published pool maintenance costs disagree

The figures disagree because each one counts different lines. One trade marketplace, last updated January 2026, says Australians spend about $600–$1,500 a year on pool maintenance. On the same page it prices the pump alone at about $80–$110 a month and says the pump might cost over $1,200 a year in total. The running-cost guide’s $1,200–$2,500 counts power, chemicals and water for a 50,000-litre pool at 33c/kWh, and says professional servicing and heating can push the total past $5,000.

Three lines decide where you land:

• Heating. The same guide puts gas heating at $100–$250 a month over a six-month season, against $16–$40 for solar. See whether a pool heater is worth it.
• The pump. Its own comparison has a 6-star pump at 657 kWh a year and a 9-star at 305 kWh. Pool running costs per year has the line-by-line split.
• Salt or chlorine. A salt pool trades bought chlorine for cell wear; the salt water pool ledger prices it at $205–$716 a year before acid and pump power.

When a pool is expensive to maintain

The ratio holds for an unheated pool that its owner looks after. It changes in four situations:

• You heat it with gas, which can add $600–$1,500 over a six-month season on the guide’s figures; the top of that is more than the whole DIY baseline at its low end.
• You pay for weekly service, which takes the year to 7.0–11.4% of a $65,000 build.
• The pool is concrete and due for resurfacing. The running-cost guide says concrete pools usually need resurfacing or an acid wash every 10 to 15 years; pool resurfacing cost has the prices.
• It is left uncovered. The guide cites Bureau of Meteorology data of 7.4 mm a day of evaporation at Sydney Airport in December, up to 5,300 litres a month from a 6 × 4 m pool; pool cover cost and payback works through the saving.

If you are still deciding whether to build, compare the yearly figure with the build price on the same basis: ask each builder for the pump’s star rating, the chlorinator model and the heater type, then compare free pool quotes on identical equipment. Heating and whether a pool adds value are the other two halves of the decision.
