If you own a swimming pool, the pump is one of the biggest ongoing energy expenses. In 2026, electricity rates continue to rise across the U.S., making it important to understand how much your pool pump really costs to run.
On average, homeowners spend $30 to $150 per month running a pool pump, depending on pump size, runtime, and electricity rates.
Let’s break it down.
How Much Electricity Does a Pool Pump Use?
Most residential pool pumps use:
- 0.75 HP to 2.5 HP
- 1,100 to 2,500 watts per hour
Here’s a quick estimate:
| Pump Size | Watts | 8 Hours/Day | Monthly Cost ($0.15/kWh) |
|---|---|---|---|
| 1 HP | ~1,500W | 12 kWh/day | ~$54/month |
| 1.5 HP | ~2,000W | 16 kWh/day | ~$72/month |
| 2 HP | ~2,500W | 20 kWh/day | ~$90/month |
If electricity costs $0.25/kWh (common in some states), costs rise quickly.
Single-Speed vs Variable-Speed Pump
This is where the real difference happens.
Single-Speed Pump
- Runs at full power
- Cheapest upfront
- Highest monthly electricity cost
Variable-Speed Pump
- Adjusts speed
- Uses up to 70% less electricity
- Higher upfront cost
- Much lower monthly bills
Example:
A variable-speed pump may cost $1,000 more to install but save $600+ per year in electricity.
That’s not cosmetic. That’s math.
How Long Should You Run a Pool Pump?
Most experts recommend:
- 6–8 hours per day in mild climates
- 8–12 hours per day in hotter regions
Running it 24/7 is almost never necessary.
Reducing runtime by 2 hours per day can save $15–$40 per month.
Real Example Calculation
Let’s assume:
- 1.5 HP pump
- 2,000 watts
- 8 hours per day
- $0.18/kWh electricity rate
Daily use = 16 kWh
Monthly use ≈ 480 kWh
Monthly cost = $86
That’s comparable to running central air part-time.
How to Reduce Pool Pump Costs
- Switch to variable-speed
- Reduce runtime
- Install a timer
- Maintain filters regularly
- Consider solar pool heating

FAQ
Is a pool pump expensive to run?
It can be. Single-speed pumps can cost over $1,000 per year in electricity.
Does running the pump at night save money?
Only if your utility offers time-of-use pricing.
How long does a pool pump last?
Typically 8–12 years.
Is a variable-speed pump worth it?
In most cases, yes — especially in states with high electricity rates.
