Pond Calculator
Use the tools below to calculate your pond's estimated water volume, surface area, pond liner size, pump head pressure, pump flow rate, and pump usage cost.
Estimating Surface Area
(For irregular shapes use the average measurements for length and width)
Please enter all values in whole numbers or in decimal format. For example, use 1.5 feet for a foot and a half!
Estimating your pond's water volume
(For irregular shapes use the average measurements for length and width)
Please enter all values in whole numbers or in decimal format. For example, use 1.5 feet for a foot and a half!
Pond Liner Size
(For irregular shapes use the average measurements for length and width)
Please enter all values in whole numbers or in decimal format. For example, use 1.5 feet for a foot and a half!
Pump Head Pressure
For waterfalls and streams, you will want to consider the amount of pump head pressure
(generally referred to on pump flow charts as "Head") that your system will have, in order to
help you determine the correct pump size.
Pump Flow Rate
You will want to size your pump to provide the water depth you're planning for your waterfall spillway and/or stream. Use this calculator to help you estimate the pump's flow rate (GPH) to achieve your desired flow..
Pump Cost/Usage
Pond pumps should run 24 hours a day to maintain your pond's ecosystem. To estimate what running your pump will
cost each day, simply plug your pump's watt rating and your cost of a kw/hr into the calculator below.
Please enter all values in whole numbers or in decimal format. For example, use .09 for 9 cents!
