Pool Running Cost Calculator
Calculates monthly/annual electricity and chemical costs based on pump type, runtime, heater use, and chemical program.
How it works
Electricity: (HP × 0.746 × Hours × Days) ÷ 1000 × RateHeater: (BTU ÷ 3412) × Runtime × Days × RateChemicals: ($25-80/mo) ÷ pool
- You enter
- Pump type (single/variable speed), pump HP, pump runtime (hours), heater type, heater BTU, heater season (months), chemical program, pool volume, electricity rate ($/kWh)
- You get
- Monthly electricity cost, monthly chemical cost, annual operating cost, payback period if upgrade
How accurate is it? Estimates based on average efficiency; actual usage varies by duty cycle; heater seasonal (typically 4-8 months).
These are estimates, not quotes. See How We Estimate.
Worked example
1.5 HP pump 8 hrs/day year-round + 60K BTU heater 6 months: Pump ~$35-45/mo; Heater add $15-25/mo in season = ~$750/yr at $0.12/kWh.

Reference table
| Pump | Typical draw |
|---|---|
| Variable-speed, low speed | 300–800 W |
| Variable-speed, high speed | 1,500–2,000 W |
| Single-speed, 1.5 HP | 1,800–2,400 W |
When to use it
Estimates operational expenses for budget planning; evaluates savings from pump/heater upgrades.
Understanding monthly expenses, evaluating variable-speed pump ROI, assessing heater efficiency, energy audit.
