# Pool Care Calculators > Free pool care calculators and reference pages for pool salt, chlorine, pH, alkalinity, stabilizer/CYA, pool volume, shock dose, pump flow, and heating cost planning. Pool Care Calculators is a browser-based utility site for pool owners who need fast pool math with visible formulas, assumptions, retest guidance, and source notes. The site does not require an account and does not store calculator inputs on a server. Use product labels, equipment manuals, and local requirements for final dosing and equipment decisions. ## Primary Pages - [Home](https://poolcarecalculators.com/) - Problem-first entry point for pool care calculations. - [All Pool Care Calculators](https://poolcarecalculators.com/pool-care-calculators/) - Main calculator library and hub. - [Pool Calculator Methodology](https://poolcarecalculators.com/pool-calculator-methodology/) - How formulas, assumptions, and boundaries are handled. - [Sources](https://poolcarecalculators.com/sources/) - References used to check formulas, chemistry guidance, conversions, and safety notes. - [Editorial Policy](https://poolcarecalculators.com/editorial-policy/) - Editorial standards, update process, corrections, and source handling. - [Sitemap](https://poolcarecalculators.com/sitemap.xml) - Full crawlable URL list. ## Core Calculators - [Pool Salt Calculator](https://poolcarecalculators.com/pool-salt-calculator/) - Pounds of pool salt, 40 lb bags, cost, staged add plan, and high-salt dilution guidance. - [Pool Chlorine Calculator](https://poolcarecalculators.com/pool-chlorine-calculator/) - Liquid chlorine, bleach, and cal-hypo estimates from gallons and free chlorine target. - [Pool pH Calculator](https://poolcarecalculators.com/pool-ph-calculator/) - Conservative muriatic acid or soda ash estimate with staged dosing guidance. - [Pool Alkalinity Calculator](https://poolcarecalculators.com/pool-alkalinity-calculator/) - Baking soda estimates for raising total alkalinity and acid-stage guidance for high alkalinity. - [Pool Stabilizer Calculator](https://poolcarecalculators.com/pool-stabilizer-calculator/) - Cyanuric acid stabilizer dose and high-CYA dilution guidance. - [Pool Volume Calculator](https://poolcarecalculators.com/pool-volume-calculator/) - Gallons estimate for rectangular, round, and surface-area pool measurements. - [Pool Shock Calculator](https://poolcarecalculators.com/pool-shock-calculator/) - Shock dose estimate with CYA-aware target planning and product-strength handling. - [Pool Pump Size Calculator](https://poolcarecalculators.com/pool-pump-size-calculator/) - Required GPM from pool gallons and turnover time, with filter-limit warnings. - [Pool Heating Cost Calculator](https://poolcarecalculators.com/pool-heating-cost-calculator/) - Heat-up BTU, fuel, runtime, and cost estimate from gallons, temperature rise, heater type, and energy price. ## Answer Pages - [Pool Answers](https://poolcarecalculators.com/answers/) - Worked examples for common gallon sizes, including salt, chlorine, shock, and pump flow. - Example answer pages use fixed assumptions and are intended as quick worked examples. Use the matching calculator for actual readings, product strengths, and targets. ## Reference Pages - [Pool Reference Charts](https://poolcarecalculators.com/reference/) - Index of chart-style pool math references. - [Pool Salt Chart](https://poolcarecalculators.com/reference/pool-salt-chart/) - Salt additions by gallon size and ppm increase. - [Chlorine Dosing Chart](https://poolcarecalculators.com/reference/chlorine-dosing-chart/) - Free chlorine dosing examples by gallons, ppm increase, and product type. - [FC/CYA Chart](https://poolcarecalculators.com/reference/fc-cya-chart/) - Free chlorine and CYA planning table with method notes. - [Pool Volume Chart](https://poolcarecalculators.com/reference/pool-volume-chart/) - Common pool gallon estimates and volume formulas. ## Troubleshooting Help - [Pool Help](https://poolcarecalculators.com/help/) - Test-first troubleshooting paths connected to calculators. - [Green Pool Water](https://poolcarecalculators.com/help/green-pool-water/) - Checklist for testing chlorine, CYA, pH, and filtration before treatment. - [Cloudy Pool Water](https://poolcarecalculators.com/help/cloudy-pool-water/) - Common causes and calculator paths for cloudy water. - [Low Chlorine](https://poolcarecalculators.com/help/low-chlorine/) - How to evaluate low free chlorine before adding more product. - [High CYA](https://poolcarecalculators.com/help/high-cya/) - Stabilizer and dilution guidance. - [pH Keeps Rising](https://poolcarecalculators.com/help/ph-keeps-rising/) - pH and alkalinity troubleshooting path. ## Important Boundaries - The calculators provide estimates, not professional pool service instructions. - Chemical results depend on test accuracy, product strength, water volume, equipment behavior, and local conditions. - Salt, chlorine, stabilizer, acid, and alkalinity changes should be made in stages when the correction is large. - Never mix pool chemicals. Follow product labels and CDC pool chemical safety guidance. - Pump size and heating-cost pages provide planning estimates, not final equipment specifications. ## Site Metadata - Site: https://poolcarecalculators.com/ - Language: English - Last updated: 2026-07-10 - Canonical sitemap: https://poolcarecalculators.com/sitemap.xml
