Pool Costs
What your pool pump costs to run, in watts and dollars
The pump is the single largest running cost of owning a pool, and it is the one number in this category that you can compute exactly - if the manufacturer publishes the wattage.

The short version
- The formula is four numbers: watts, hours a day, days in season, and your electricity rate. Nothing else is needed and nothing else is honest.
- At the EIA US residential average of 18.34 cents per kWh (June 2026), every 100 W of pump run 8 hours a day for 120 days costs about $17.61.
- Intex and Bestway do not publish pump wattage. They publish flow rate, which tells you nothing about electricity. The label on the unit is the only reliable source.
- A timer is the highest-return purchase in this hub: cutting two hours a day off a 300 W pump saves roughly $40 across a season at the national average rate.
The formula, and why it is the whole article
Electricity is the one pool cost that can be computed exactly rather than estimated. Watts multiplied by hours gives you watt-hours; divide by 1,000 for kilowatt-hours; multiply by your rate. That is it. Every confident dollar figure you read about pool pumps is this arithmetic with someone else’s assumptions baked in, so it is worth doing with your own.
Pump electricity, for any pump
- Pump wattage
- on the pump label
- Hours per day
- your run time
- Days in season
- 120 (our example)
- US residential average rate, June 2026 [EIA]
- 18.34 ¢/kWh
kWh = watts × hours/day × days ÷ 1,000 cost = kWh × your rate
Every 100 W of pump, run 8 h/day for 120 days, costs about $17.61
| Pump draw | kWh per season | Cost at 18.34¢/kWh |
|---|---|---|
| 100 W | 96 | $17.61 |
| 200 W | 192 | $35.21 |
| 300 W | 288 | $52.82 |
| 450 W | 432 | $79.23 |
| 600 W | 576 | $105.64 |
| 900 W | 864 | $158.46 |
The problem: almost nobody publishes wattage
We went through the manufacturer specification pages for the pumps in this category and the pattern is consistent. Intex publishes flow rates for the Krystal Clear range — a 530 GPH pump with a 475 GPH system flow, a 1,000 GPH pump with a 750 GPH system flow — and does not publish wattage. Bestway is the same. Flow rate tells you whether a pump can turn your water over; it tells you nothing whatsoever about what it costs to do so.
So the honest advice is unglamorous: read the label on the unit, or on the motor nameplate, before you accept anyone’s dollar figure. If you are shopping and the wattage is not in the listing, ask for it, and treat its absence as information. Our pump roundup flags exactly which manufacturers publish it and which do not.
What ENERGY STAR implies, if you have no label at all
There is one published route to a plausible figure when you genuinely cannot find a wattage. ENERGY STAR publishes that a certified above-ground pool pump saves about $20 a year and is about 11 percent more efficient than a standard one. Work backwards from those two numbers and you get an implied annual electricity cost for a standard above-ground pump.
Working backwards from ENERGY STAR's own figures
- Annual saving from a certified above-ground pump [ENERGY STAR]
- $20
- Efficiency gain of that certified pump [ENERGY STAR]
- 11%
- US residential average rate, June 2026 [EIA]
- 18.34 ¢/kWh
$20 ÷ 0.11 ≈ $182/year $182 ÷ $0.1834 ≈ 992 kWh/year
≈ $182 a year, or about 992 kWh
The lever that actually moves the number
You have two variables: watts and hours. Watts are fixed once you have bought the pump. Hours are entirely yours, and they are where the money is. Cutting two hours a day off a 300 W pump across a 120-day season saves 72 kWh, which is about $13 at the national average — and cutting four hours saves double that. On a larger pump the numbers get more interesting quickly.
What two hours a day is worth
- Pump draw
- 300 W
- Hours saved per day
- 2
- Days in season
- 120
- US residential average rate, June 2026 [EIA]
- 18.34 ¢/kWh
300 × 2 × 120 ÷ 1,000 = 72 kWh 72 × $0.1834 = $13.20
About $13 a season, from one timer setting
Where this fits in the whole cost
Electricity is the biggest single line, but it is not the whole bill. Water, chemicals and consumables sit alongside it, and on a small pool the chemical line can rival the electrical one. Our annual cost-to-run guide adds all of it up for a worked example, our chemical cost guide does the same for the chemistry, and the cost to fill covers the water. If you want the short version of all three, our cheapest honest setup page builds the whole thing from the bottom up.

Cutting the electricity bill without cutting filtration
Outdoor Pool Pump Timer
Various
A weatherproof outdoor timer is the highest-return equipment purchase on this site. Most people run the pump too long because remembering to switch it off is a chore.

What works
- Turns your filtration from a guess into a schedule
- Pays for itself within a single season on most pools
- Lets you shift running hours to off-peak if your utility has time-of-use rates
What doesn't
- Must be genuinely outdoor-rated and correctly amperage-matched, which cheap indoor timers are not
- Never bypass or defeat the pump's GFCI to fit one
- Mechanical timers drift and need resetting after a power cut
Skip it if: Fixing an undersized pump. Running the wrong pump on a schedule just makes the schedule longer.
What it costs to run: The arithmetic that justifies it: at the EIA's June 2026 US residential average of 18.34 cents per kWh, trimming a 400 W pump from 12 hours to 8 hours a day across a 120-day season saves 192 kWh, or about $35. That is more than the timer costs.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.

Small frame and inflatable pools
Intex Krystal Clear C530 Cartridge Filter Pump
Intex
530 GPH pump flow, 475 GPH through the system. The right pump for a 12-foot pool and badly undersized for anything much bigger.

What works
- Correctly matched to the 12ft Prism Frame and Easy Set pools it ships with
- Smallest pump here that will still genuinely turn over a real pool
- Type A cartridges, which are everywhere
What doesn't
- Undersized the moment you upgrade the pool, and it will not carry over
- No wattage published
- Cartridge needs rinsing frequently in a busy small pool
Skip it if: Anything over about 2,000 gallons. Below that it is right; above it you are running it all day for one turnover.
What it costs to run: 475 GPH system flow turns over 1,718 gallons in about 3.6 hours, so a 7-hour daily run is two full turnovers. That is a genuinely short run time and it is where a small pool's low running cost actually comes from.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

Pools up to about 6,000 gallons
Intex Krystal Clear C1000 Cartridge Filter Pump
Intex
The workhorse replacement pump for mid-size frame pools. 1,000 GPH pump flow, 750 GPH through the system once the cartridge is in the way — and that second number is the one your turnover math needs.

What works
- Intex publishes both pump flow and system flow, which is more honesty than most of this category offers
- Type A cartridges are the most widely stocked filter consumable in the US
- Sized correctly for the 12ft-15ft frame pools most families own
What doesn't
- Wattage is not published anywhere on the Intex site, so you cannot cost it before purchase
- Cartridge-only, so there is a consumable every few weeks in a busy pool
- GFCI cord length dictates where the pool can go more than people expect
Skip it if: Pools over about 6,000 gallons. Above that you are asking it to run all day to achieve one turnover, which is the expensive way to filter.
What it costs to run: Do the turnover math before you buy: 750 GPH system flow moves 4,000 gallons in 5.3 hours. Two turnovers a day is therefore about 11 hours of running. At the EIA's June 2026 US residential average of 18.34 cents per kWh, every 100 watts of pump draw running 11 hours a day for a 120-day season costs about $24. Find your wattage on the pump label and multiply.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.

Getting off the cartridge treadmill
Intex Krystal Clear Sand Filter Pump
Intex
Sand filtration replaces a recurring cartridge purchase with a backwash valve and a bag of sand that lasts years. On a pool you intend to keep, the arithmetic favors it.
Key specs
- Media
- Filter sand (or glass media)
- Maintenance
- Backwash rather than rinse-and-replace
- Media life
- Several seasons before replacement
- Wattage
- Not published by Intex

Overall 8.4 / 10
What works
- No cartridges to buy, which removes the single largest recurring equipment cost
- Backwashing takes about two minutes versus rinsing a cartridge in the yard
- Sand lasts years rather than weeks
What doesn't
- Backwashing sends water down the drain, and that water has chemicals in it you paid for
- Higher purchase price than a cartridge pump of the same flow
- Heavier and needs a stable, level base of its own
Skip it if: A small seasonal pool that comes down every autumn. The payback period is measured in seasons, so it only works if there will be seasons.
What it costs to run: The comparison to run: cartridge replacements per season versus one bag of sand every few years, plus the water each backwash discards at the EPA WaterSense average of $6.06 per 1,000 gallons. On a pool you will own for three or more years, sand usually wins.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.
