Keeping pool water balanced comes down to chlorine, pH, alkalinity and salt for saltwater systems. Our chemistry calculators help estimate how much chlorine, shock, salt, muriatic acid or baking soda you may need based on your pool size and readings.
Explore Water ChemistryAn undersized pump can struggle to circulate water, while an oversized one can use more energy than necessary. Heater sizing also depends on pool size, climate and the temperature increase you need. Our tools help you plan before buying equipment.
Explore Pool EquipmentMany pool calculations start with knowing how much water the pool holds. Shape, length, width and average depth all affect the result. Our volume tools help you calculate gallons you can then use in other pool-care calculations.
Explore Pool VolumePool heating and equipment use can be significant ongoing expenses. Cost estimates depend on factors such as heater type, energy price, pool size and temperature change. Our cost tools help you plan before the bill arrives.
Explore Pool CostsOne calculation often leads to another. Start with your pool volume when needed, then use the related chemistry, equipment or cost calculator for the next step.
PoolTaken is a simple set of pool calculators built for everyday pool care. Instead of guessing how much salt, chlorine or acid your pool needs, you enter your pool details and get a clear, usable answer in seconds. The tools cover the things pool owners look up again and again: water chemistry, pump and heater sizing, pool volume and running costs, all organized into the categories above so you can find what you need quickly.

Pool volume depends on its shape, length, width and average depth, and round, rectangular and oval pools each use a different formula. Use our Pool Volume calculators to get an accurate gallon count for your pool instead of relying on a rough estimate.
The amount of salt to add depends on your pool's volume and how your current salt reading compares to the target level for your salt system. Our Water Chemistry calculators work this out for you, so you add the right amount instead of guessing.
Pump size depends mainly on your pool's volume and how many hours a day you want the water to turn over. Too small and the water will not circulate properly; too large wastes electricity. Our Pool Equipment calculators help you work out a suitable pump size and run time for your pool.
Yes. Every calculator on PoolTaken works the same way on a phone, tablet or desktop, so you can check numbers poolside without needing a computer.
