Arrow speed calculator is specifically programmed to calculate bow/arrow speed. Yes, this arrow calculator does calculations as per the rules set by the International Bowhunting Organization to estimate how fast the arrow being shot by your bow can travel.

Bow Speed IBO Characteristics:

The International Bowhunting Organization (IBO) has established guidelines to calculate arrow speed for different bow types. These include:

Draw weight of approximately 70 lb
Arrow length of 30 inches
Arrow weight of at least 350 grains

One key factor is the arrow’s weight. Heavier arrows generally move faster, while lighter arrows are slower. To check how fast a particular arrow will travel based on its weight, you can use this free arrow weight calculator for instant calculations.

Arrow Speed Formula:

The speed of an arrow can be calculated using the following equation:

v = IBO + (L − 30) × 10 − W/3 + min(0, −(A − 5D/3))

Where:

v = Actual arrow speed in feet per second (ft/s)

IBO = Speed of the arrow according to IBO specifications

L = Draw length in inches

W = Additional weight added to the bowstring

A = Weight of the arrow in grains

D = Draw weight in pounds

All these factors affect arrow speed, which can be instantly calculated using the online archery kinetic energy calculator.

How the Archery Arrow Speed Calculator Works

Here’s a step-by-step guide on using the free archery speed calculator to determine arrow speed instantly:

Input:

Enter the Bow IBO rating and Draw Length of the bow in the first fields
Enter the Peak Draw Weight and Arrow Weight in their respective fields
Optionally, enter any additional weight added to the bowstring
After filling all fields, click the Calculate button

Output: The free bow speed calculator provides:

Arrow speed
Arrow momentum
Arrow kinetic energy

You can also calculate the kinetic and potential energies of any moving object using our free kinetic energy calculator and potential energy calculator.
