What does your pool actually cost to run — and how much could you save?
Illustrative monthly operating costs for an Arizona pool: water, energy, and chemicals. Compare modeled variable-speed pump, automatic cover, and solar pre-heat scenarios — with simple payback examples, not guaranteed savings.
No cover replaces active adult supervision. Designate an undistracted adult Water Watcher whenever children are in or near water. Covers, barriers, and alarms are layers of protection; confirm local-authority requirements and manufacturer approval for the specific cover and installation before treating it as a safety barrier.
Modeled monthly operating costs
Seasonal weights applied to each cost line — evaporation peaks Jun–Aug, heating runs Oct–Apr, pump and chemicals shift slightly with water temperature.

What each change saves in this model
Installed investment ranges below are illustrative planning assumptions, not verified AE pricing or current quotes. Simple payback divides the midpoint investment by modeled annual savings; upgrades are evaluated separately, so savings should not be added together. No rebate is included. Verify current utility program terms and eligibility before counting any incentive.
Variable-speed pump
Pentair IntelliFlo3 or equivalent is an example, not a specified product. Match speed and flow to the required operation. No rebate is included; verify current equipment and program eligibility with your utility.
Automatic safety cover
The model assumes 70% less evaporation and 50% less heating expense with consistent use. A cover is not automatically an approved barrier: confirm the specific system with the local authority and manufacturer. No cover replaces active adult supervision.
Solar pre-heat panels
Illustrative solar option, not a universal recommendation. Roof exposure, system compatibility, desired temperature, and backup-heater use matter; the model substitutes a solar baseline rather than simulating combined heater operation.
How these numbers are built
The fixed assumptions below let you check the math. Compare them with your actual bills and equipment; this calculator does not accept custom utility rates. Bring those records when discussing a project-specific review.
Rate assumptions (2024 snapshot — verify with your current utility bill)
- Water + sewer: $5.25 per 1,000 gal (City of Phoenix blended residential, 2024 rate snapshot).
- Electricity: $0.145 per kWh (APS/SRP blended residential, summer-weighted, 2024 rate snapshot).
- Natural gas: $1.45 per therm (Southwest Gas residential, 2024 rate snapshot).
- Evaporation: 0.18 in/day annual average for Phoenix (NWS climate normals + ASHRAE pool evaporation formula).
Utility rates change annually. Compare against your most recent bill and adjust your expectations up or down accordingly.
Calculation formulas
- Water: surface sf × in/day × 0.6234 = gal/day. Shade reduces evaporation up to 30%. Manual cover cuts evaporation ~35%, auto cover ~70%.
- Pump: annual kWh by pump type × electricity rate. The fixed annual assumptions are 2,400 kWh single-speed, 1,500 two-speed, and 520 variable-speed; they are not measured usage or a prescribed runtime. Match speed to the flow needed for each operation. Actual savings depend on equipment and operation.
- Heating: baseline by heater type, scaled to pool gallons, reduced by cover (manual -30%, auto -50%). Assumes ~6 months of active heating to ~80°F.
- Chemicals: $550/yr baseline for a 17k-gal pool, scaled by volume, -15% with any cover.
Pump example: (2,400 − 520) kWh/year × $0.145/kWh = $272.60/year. Simple payback = illustrative installed investment ÷ modeled annual savings. Heating uses fixed annual dollar baselines ($2,800 gas, $1,300 heat pump, $250 solar), scaled by volume and cover; the listed gas rate is context, not a separate multiplier in that calculation. Cover, chemical, evaporation, and seasonal factors are model assumptions, not verified results for your pool.

- Pool Safely: layers of protection and active adult supervision
- CPSC: safety barrier guidance (not a substitute for local requirements)
Model limitations
No statistical confidence interval has been established for this model. Heating is the biggest swing variable — set point, swim season length, and weather can move it materially. If you heat year-round to 86°F you'll see higher numbers; if you only heat April–May and Sept–Oct, lower.
Simple payback holds rates and modeled annual savings constant, excludes financing and maintenance, and does not predict future utility prices. Actual rates and usage can lengthen or shorten payback. Rebates are not assumed; verify current program terms and eligibility directly with your utility.
This is not a billing forecast or appraisal. Your last 12 months of utility bills and equipment nameplate data can inform a project-specific review; its scope and any measurements must be agreed separately.
What this is not
We don't connect to your pool equipment or read your utility bills. This is a planning tool, not telemetry. Request an efficiency review to discuss your actual usage, available records, and what additional measurements may be needed. Confirm deliverables in the agreed scope.

Arizona pool operating-cost questions
How much does it cost to run a pool in Arizona per month?
There is no single monthly figure for every Arizona pool. This model combines evaporation refill, pump electricity, heating, and chemicals. The default includes natural-gas heating; selecting Not heated changes the result substantially. Monthly results are illustrative seasonal allocations, not utility bills. Compare the historical 2024 rate assumptions with your current bill and account for your equipment, usage, weather, and heating preferences.
Is a variable-speed pump worth it?
It depends on your existing pump, operating schedule, required flow, electricity rate, and installed price. This example assumes 2,400 versus 520 kWh/year at $0.145/kWh: (2400 − 520) × $0.145 = $272.60/year. An illustrative $1,800–$3,200 installed investment divided by that annual saving gives 6.6–11.7 years of simple payback (about 9.2 years at the midpoint). These are model assumptions, not typical savings, current quotes, or a promised result; rebates, financing, maintenance, and future rate changes are not included.
