Bow Speed (FPS) Calculator

Estimate realistic bow speed by adjusting from IBO benchmark conditions.

Estimated Bow Speed: 0.0 fps
Speed = IBO + (DW-70) + 10 x (DL-30) - ((Arrow Weight-350)/5) - string penalty.

FOC Guide

Speed alone does not define performance. Pair this page with FOC checks to keep flight stable while adjusting draw specs and total arrow mass.

FAQ

Why is my estimated speed lower than IBO?

Most real setups use heavier arrows and different draw specs than IBO test conditions.

Should I trust this instead of a chronograph?

Use it for planning, then verify exact speed with a chronograph.

Does string accessory weight matter?

Yes. Added string weight can reduce launch speed, especially on lighter setups.

Bow Speed Calculator

This page supports archery physics decisions with arrow velocity in feet per second (fps), draw weight, draw length, IBO assumptions, and spine deflection context. Use these values together to compare realistic compound bow, recurve, and crossbow setup outcomes.
