The arrow ballistics calculator below will help you determine your arrow’s vertical drop, speed, kinetic energy and momentum, for up to 70 yards out in 10 yard increments. You will need to provide total arrow weight and initial speed for the calculation to be effective, as well as some other optional info (see below). The calculator assumes average air density and air viscosity. Actual ballistics data will vary slightly based on weather conditions and how high above sea level you are. These will result in relatively small variations that you should not worry much about. Values below should be considered very close estimates of what you will experience in the field (a 2% margin of error should be assumed).
Calculations are largely based on the Exterior Ballistics of Bows and Arrows paper.
