How much does pool maintenance cost per year?

Annual pool maintenance costs $1,500–$3,500 in 2026 for chlorine pools (chemicals, equipment, electricity, water). Saltwater systems run $200–$400 less per year on chemicals but cost $1,200–$2,500 more upfront. Heating adds $500–$2,500/year depending on pool size, climate, and heater type (electric heat pump cheapest to operate, gas fastest). Cleaning service (weekly/bi-weekly) adds $1,500–$3,500/year if outsourced. Major equipment hits: liner replacement $4K–$8K every 8–12 years (vinyl), variable-speed pump replacement $800–$1,500 every 10–15 years, heater replacement $2K–$5K every 8–12 years.
