Pool Pump Running Cost Calculator
For many Australian households, the pool pump is the single largest consumer of electricity, often accounting for up to 30% of a summer energy bill. With electricity prices in Victoria and across the country remaining a significant concern, understanding exactly how much your "Blue Haven" is costing you is the first step toward massive savings.

The Math Behind the Momentum: Wattage vs. Dollars
Most older pools in Australia operate on a single-speed pump. These machines are built for one thing: running at full power, all the time. A typical 1.5 HP single-speed pump pulls roughly 1,000 to 1,500 watts. At an average Victorian electricity rate of 30c per kWh, running that pump for 8 hours a day costs roughly $3.60 per day. While that sounds small, it totals over $1,300 per year.
The Variable Speed Revolution
The "secret" to saving over $800 a year isn’t running your pump less—it’s running it smarter. Modern Variable Speed Pumps (VSPs) allow you to drop the flow rate for everyday filtration.
Because of the Pump Affinity Laws, if you halve the speed of a pump, you actually reduce the power consumption by nearly eight-fold.
3 Ways to Slash Costs Today
- Offset with Solar: Run your pump between 10 AM and 3 PM to use your own solar generation.
- Clean Your Filters: Dirty filters create back-pressure, forcing the pump to draw more wattage.
- Check Your Tariff: Use Off-Peak rates (usually overnight) if you don't have solar.
Frequently Asked Questions
What is a good electricity rate to use?
In 2026, the average Australian residential rate is approximately $0.32 per kWh. Check your latest bill for the "Usage" or "General Purpose" rate.
Should I run my pump during the day or night?
If you have solar, run it during peak sun (10am - 2pm). If you don't have solar but are on an off-peak plan, running it after 11pm is usually cheapest.
"Upgrading from a standard pump to a variable speed model can often pay for itself in energy savings within just 18 to 24 months."
