Cost to run a pool pump in New Hampshire

At New Hampshire’s average residential rate of 27.33¢ per kWh, a pool pump drawing 1500W for 8 hours a day costs about $99.83 a month. Change the numbers below to match how you actually use yours.

Summers in New Hampshire are humid enough for cooling to matter, but the season is compressed. Most of a pool pump's annual consumption will land in a few peak weeks rather than spreading evenly across the year.

Why the cost differs in New Hampshire

New Hampshire has the 43rd cheapest residential electricity of the 51 US states and territories we track, at 27.33¢ per kWh against a national average of 18.44¢. That is +48.2% compared with the national figure. New Hampshire shares New England's pricing dynamics: winter natural gas pipeline constraints raise generation costs precisely when heating demand peaks. Retail supplier choice is available. Heating dominates annual consumption, and the state's older housing stock means envelope efficiency varies widely, so identical appliances can produce very different bills between neighbouring homes.

For this appliance specifically, the difference works out to an extra $389 a year over what the same pool pump would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $2,278 a year; in Idaho it would cost $541. That spread of $1,737 is entirely down to location.

At New Hampshire's rate this single pool pump accounts for roughly 42% of a typical household's entire annual electricity bill. It is not a rounding error on your statement - it is one of the largest single line items in it.

New Hampshire sits above the national average, so the running cost of this pool pump is modestly higher than a typical US household would pay. Usage habits still matter more than location at this rate level.

Because New Hampshire has retail supplier choice, the state average blends many different contracted rates. If you have shopped for a plan, your own price per kWh is the number to put in the calculator.

About running a pool pump

Single-speed pool pumps are among the largest discretionary loads in a home. Variable-speed models running longer at lower speed use dramatically less energy for the same filtration.

What actually changes the cost

  • At typical use this is a major load - around 4,380 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
  • Models vary widely, from about 750W to 2500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
  • If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.

How we worked this out

The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:

1500W ÷ 1000 × 8h = 12.000 kWh/day × 27.33¢ = $3.280 per day

One honest caveat: New Hampshire’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.

Questions about pool pump running costs

How many watts does a pool pump use?

A typical pool pump draws about 1500 watts while running, with most models falling between 750W and 2500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.

How much electricity does a pool pump use per day?

At around 8 hours of use a day and a 100% duty cycle, that works out to roughly 12 kWh per day, or about 360 kWh a month. Your actual figure depends on your usage and model.

Why does the cost differ so much between states?

Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same pool pump, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.

Is it cheaper to run a pool pump at night?

Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
