How Much Does a Pool Pump Cost? Buy, Install and Run

Name: comparepoolquotes
Price range: $$$

A pool pump costs about $450–$790 for a single-speed and $1,250–$2,400 for a variable-speed at three Australian online retailers (read 4 October 2026), plus installation. To run, the median registered single-speed pump costs about $422 a year on Sydney’s 2026–27 default tariff, against $163 for the median variable-speed.

The short answer

Retail prices, read 4 October 2026: single-speed $449.99–$787.81 and variable-speed $1,249.99–$2,396.79 across three online pool and pump retailers, GST included, pump only.
Installation adds about $150–$400 on one pump retailer’s published breakdown; a pool service business publishes $500–$2,500 all-in. Both are vendor figures and they overlap rather than agree.
Running cost: $422 vs $163 a year for the median single-speed (1,274 kWh) and variable-speed (490 kWh) pump in the federal Energy Rating registry, at Ausgrid’s 2026–27 default usage rate of 33.1372c/kWh.
The saving is $203–$328 a year across Melbourne (CitiPower), south-east Queensland, Sydney and Adelaide default tariffs, so a variable-speed pump that costs $800–$1,609 more pays back in about 2.4 to 7.9 years.
The label assumes 50,000 litres pumped a day. Energy Rating’s label is built on that volume, so a bigger pool or longer run hours raise both figures in proportion.

How much does a new pool pump cost?

Pump prices are set by retailers, so here are three, read on 4 October 2026, each selling one single-speed and one variable-speed pump. Prices include GST and exclude installation.

Retailer (online)	Single-speed	Variable-speed	Gap
Pool pump retailer A	$449.99 (1.5 HP)	$1,249.99 (1.5 HP)	$800.00
Pump retailer B	$475.00 (1.5 stars, 1,228.6 kWh a year)	$1,463.80 (6 stars, 587.13 kWh a year)	$988.80
Pool equipment retailer C	$787.81 sale, $1,125.44 regular (1 star, 1,280 kWh a year)	$2,396.79 sale, $3,423.98 regular (6 stars, 510 kWh a year)	$1,608.98

The star ratings and kWh figures are from the federal Energy Rating registry for those models. The makes are listed in our sources; the price spread inside each type comes from motor size, brand and whether the price is a sale.

Across three online retailers, a variable-speed pool pump cost $800 to $1,609 more than a single-speed one on the day we read them. Which pump suits your filter and chlorinator is covered in pool equipment explained.

How much does it cost to replace a pool pump, installed?

The installation figures we could verify are from businesses that sell or fit pumps, and they do not line up neatly:

A pump retailer’s blog (December 2025): single-speed pump $250–$450 plus installation $150–$300, total $400–$750; variable-speed pump $650–$1,400 plus installation $200–$400, total $850–$1,800.
A pool service business (September 2025): $500 to $2,500 for a replacement including pump and installation.
Our equipment guide carries a Victorian marketplace’s $600–$1,100 installed for a single-speed and $1,200–$2,500 for a variable-speed.

The first source’s single-speed pump prices sit below the branded prices in the retail table above, so treat its low end with care.

A replacement pool pump quote should name the model, its star rating and its kWh a year, so you can run the table above on it. If the old pump has stopped moving water rather than failed outright, check why a pool pump is not pumping water before you replace it.

How much does a pool pump cost to run per month?

The method: annual label kWh × your usage rate. The label figure comes from the Energy Rating registry, which the federal government publishes as a data file. In the February 2026 export, 439 single-speed pumps have a median of 1,273.7 kWh a year and 176 variable-speed pumps a median of 490.44 kWh, 61% less. The usage rates are the 2026–27 default caps: the AER’s Default Market Offer for NSW, south-east Queensland and SA, and the ESC’s Victorian Default Offer.

Worked for Sydney: 1,273.7 kWh × $0.331372 = $422 a year, or about $35 a month, for the median single-speed. 490.44 × $0.331372 = $163, about $14 a month, for the median variable-speed. The other states are in the table above.

What the label assumes: Energy Rating says the pool pump label is calculated on pumping 50,000 litres of water a day. If you turn over a 70,000 litre pool daily, scale the kWh up by 1.4. How long a pool pump should run each day works out your turnover hours; the government cross-check is energy.gov.au’s statement that a 5-star variable-speed pump uses 55% less energy than a 1-star single-speed.

At Sydney’s 2026–27 default rate, the median single-speed pool pump costs about $35 a month to run and the median variable-speed about $14.

Is a variable-speed pool pump worth the extra cost?

Divide the price gap by the yearly saving. On the median pumps, the saving is 783 kWh a year, worth $203 in Melbourne (CitiPower) up to $328 in Adelaide. Against the three price gaps in the retail table ($800, $989 and $1,609), payback runs from 2.4 years (Adelaide, smallest gap) to 7.9 years (Melbourne, largest gap).

One pump retailer says most households recover the difference within one to two years. On median registry figures and 2026–27 default tariffs, we could not reproduce that: it would need a larger pool, longer run hours or a higher tariff than the label assumes.

Variable-speed pays back faster when the pump runs long hours, the pool is above the label’s 50,000 litres a day, or your usage rate is high (Adelaide’s default is the highest of the four above).
A single-speed can be the rational buy when the pool is small, the pump runs short hours, or the pump is a stop-gap before a renovation.
In NSW, check the Energy Savings Scheme. Its pool pump activity covers the new installation or replacement of a high-efficiency pool pump; check eligibility, and ask the installer whether its price reflects it.

On 2026–27 default tariffs, a variable-speed pool pump pays back its extra price in about 2 to 8 years; the gap you are quoted decides which end. For the other running-cost levers, see the best way to reduce pool running costs. For a new pool, ask every builder to name the pump and compare pool quotes on the same specification; listed businesses cover Sydney, Brisbane and Melbourne.
