Enter the length (ft), the width (ft), and the depth (ft) into the Pool Volume  Calculator. The calculator will evaluate and display the Pool Volume . 

Pool Volume Formula

The following formula is used to calculate the Pool Volume . 

PV = L*W*D /7.481

  • Where PV is the Pool Volume  (gallons)
  • L is the length (ft) 
  • W is the width (ft) 
  • D is the depth (ft) 

How to Calculate Pool Volume?

The following example problems outline how to calculate Pool Volume .

Example Problem #1

  1. First, determine the length (ft). The length (ft) is given as 20 .
  2. Next, determine the width (ft). The width (ft) is calculated as  30 .
  3. Next, determine the depth (ft). The depth (ft) is found to be 8.
  4. Finally, calculate the Pool Volume  using the formula above: 

PV = L*W*D /7.481

Inserting the values from above yields: 

PV = 20*30*8 /7.481 = 641.62 (gallons)


Example Problem #2

The variables needed for this problem are provided below:

length (ft) = 40

width (ft) = 50

depth (ft) = 4

Entering these values and solving gives:

PV = 40*50*4 /7.481 = 1069.37 (gallons)
