Welcome to the Kinetic Energy Calculator. This form will calculate the kinetic energy of your arrow, even if you don't know your arrow's speed. You simply need to enter the information in the form below, and your speed will be estimated to within a few FPS. This value will then be used, along with your arrow's weight to determine your Kinetic Energy.
You may enter the Total Arrow Weight -OR- the Broadhead Weight, Arrow Grains/Inch, Arrow Length, and Vane/Feather/Nock Weight and have the total weight calculated for you.
