For many homes, the pool pump is the second-most-expensive electricity-using appliance after the air conditioner. In Florida’s warm climate, extended filtration times during the hottest months can significantly increase your pool pump running cost if your system is not energy efficient.
At Edgewater Pool Service, we help homeowners improve energy efficiency and reduce long-term operating expenses with professional pool equipment solutions and maintenance services.
The total pool pump running cost depends on three main factors:
- The wattage or horsepower of your pool pump
- The number of hours the pump runs each day
- Your electricity rate
In Southwest Florida, the electricity rate for FPL customers in 2026 is approximately 12–14 cents per kilowatt-hour. Below, we break down the estimated pool pump running cost for different pump types.
How to Calculate Your Pool Pump's Running Cost
The formula is straightforward:
Daily cost = (Pump wattage / 1,000) × Hours run per day × Cost per kWh
| Pump Type | Wattage | 8 hrs/day @ $0.13/kWh | Monthly Cost |
| 1 HP single-speed | 750W | $0.78/day | ~$23/month |
| 1.5 HP single-speed | 1,125W | $1.17/day | ~$35/month |
| 2 HP single-speed | 1,500W | $1.56/day | ~$47/month |
| 1.5 HP variable-speed (low) | 200–300W | $0.21–0.31/day | ~$6–9/month |
| 1.5 HP variable-speed (high) | 800–1,000W | $0.83–1.04/day | ~$25–31/month |
One example of the cost savings is a single-speed 1.5 HP pump running 8 hours a day for a year. Based on an average cost of $0.10/kWh, the annual energy cost would be $420.00 to $500.00.
But a variable-speed pump can run the same pool with the same water quality for 50–80% less energy for filtration and circulation. That would cost $210.00 to $300.00 per year for energy. In this example, the variable-speed pump would pay for itself in 2 to 3 years.
Single-Speed vs. Variable-Speed Pumps: The Real Cost Difference
Single-Speed Pumps
Single-speed pumps are typically rated based on their highest performance rating, which they maintain 24 hours a day. They can be an inexpensive upfront purchase ($200–$500).
This type of pump is most efficient for short-term, high-power tasks, such as:
- Vacuuming
- Running spa jets
- Backwashing your filter
However, running them continuously to circulate and filter water in your pool can be a waste of energy.
Variable-Speed Pumps
Variable-speed pool pumps use permanent-magnet motors similar to those used in hybrid vehicles. These pumps automatically adjust speed depending on the pool’s needs, greatly reducing overall pool pump running cost.
Low-speed operation handles everyday filtration efficiently, while higher speeds are used temporarily for cleaning, spa jets, or backwashing.
Energy-efficient variable-speed pumps over 1 HP are now required for most new pool construction in Florida under updated building codes.
Homeowners looking for professional pool equipment services can benefit from upgrading to a modern variable-speed system for long-term energy savings.
Benefits of Variable-Speed Pumps
- 50–80% energy savings on filtration and circulation
- Quieter operation — runs nearly silent at low speed
- Longer life for your pump: Because VSPs run at lower RPMs, they put less wear and tear on your pump
- Better filtration — Because VSPs run longer at low speeds, they filter more water per day
- Eligible for FPL rebates in some service areas
How Many Hours a Day Should You Run Your Pool Pump in Florida?
The standard time for most pools to be “cycled,” or for the pool water to be completely turned over, is once per day.
For the average-sized residential pool (holding between 10,000 and 20,000 gallons of water), this translates to running the pumps:
- 8–12 hours per day in the summer
- 6–8 hours per day in the winter
Summer (May–October)
Run your pool pump 8–12 hours per day. Heat accelerates algae growth and chemical consumption. Longer run times are necessary.
Winter (November–April)
We typically recommend running your pool filtration system for 6–8 hours per day during the cooler winter months, as the lower temperatures decrease biological activity in the pool water, helping reduce overall pool pump running cost while still maintaining clean and balanced pool water.
After heavy rainfall or very high bather load hours extra hours of operation will be required to bring the pool back under control and back into balance.
Running your pool filtration longer at a slower speed is more energy efficient than running at higher speeds for shorter periods of time. Also running at a slower speed for longer periods of time results in cleaner pool water.
Ways to Reduce Your Pool Pump Energy Cost
Upgrade to a Variable-Speed Pump
One of the most effective ways to lower pool pump running cost is upgrading from a single-speed pump to a variable-speed model. Many homeowners save hundreds of dollars annually after switching.
Modern pool upgrades such as energy-efficient variable-speed pumps can dramatically lower monthly electricity bills.
- Energy Saving – Reduce your pool energy cost by up to $400.00 per year with a single upgrade. This is one of the highest-impact changes to save energy for your pool.
- Use a timer – Run the pool pump during off-peak electricity hours (check with your local electric provider for their time-of-use pricing, i.e., FPL pricing is lowest overnight). The programmable timer on your pool pump can do this for you.
- Ensure that your pump is the correct size for your pool to avoid wasting money on operating an oversized pump.
- Clean your filter regularly – A dirty filter will restrict the amount of water that flows through your filter, and as a result, your pump will be forced to work harder in order to try and move the same amount of water through the system. Regular cleaning or backwashing of your filter will help remove debris that can clog it and cause your pump to work harder than necessary.
- Run a clean pool – Algae and other debris greatly increase the amount of work your pool filter needs to do to keep your pool clean. If you maintain the proper levels of pool chemicals, your pool filter won’t have to work as hard to keep your pool water clean.

Frequently Asked Questions
Q: How long do pool pumps last?
A: The average life of a pool pump is 8–15 years. If your pump is older than that, it may be time for a replacement. Variable-speed pumps can last longer than single-speed pumps because they operate at lower RPM, which reduces motor wear.
Q: Is it cheaper to run my pool pump at night?
A: If your utility offers a time-of-use rate (i.e., lower rates for off-peak usage), then yes, running your pool during the night could save you money. Edgewater has conducted research on the EV and time-of-use rates offered by FPL and can advise you on the best option.
Q: Can I run my pool pump less to save money?
A: There is a minimum turnover rate for your pool, and reducing the pump run time below that can create problems with your pool water, including:
- Algae growth
- Cloudy water
- Inefficient use of chemicals
This can end up costing more to fix than the energy saved by turning the pump off. A variable-speed pump would be a better way to save energy.
Q: Do I need a permit to replace my pool pump in Florida?
A: Yes. In most Florida municipalities, a permit is required to replace a pool pump. However, if you are replacing the same-size pump and do not need to make any electrical changes, no permit would be required.
At Edgewater Pool Service, we handle all the necessary paperwork for your equipment installations.
Q: How much does a variable-speed pool pump cost installed?
A: The average cost to install a new variable-speed pool pump is around $900–$1,800 in Southwest Florida. However, the savings on your energy bill will often cover the cost of the new system in 2–4 years.
