I want to be able to estimate the speed of my arrows since I do not have a chronograph.  Is there a formula for how to calculate arrow speed?

Yes, there is a formula for calculating arrow speed. Please see below.

To properly calculate arrow speed (estimated), use the following formula:

Estimated Arrow Speed (fps) = IBO Speed – (5 * (Arrow Weight(in grains) – (5 * Draw Weight (in pounds)))) / (Draw Length (in inches) / 28) + Additional Weight on Bowstring (in grains) / 3

But, there is an easier way.  Take a look at our Arrow Speed Calculator here.
