How easy was it to use our calculator? Did you face any problem, tell us!

The online 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.

So if you have bought the bow-arrow set for hunting or gaming purpose, go through the read below as it is packed with the most up to date guide on calculating the speed arrows’ speed accordingly.

Let’s move on to it!

Bow Speed IBO Characteristics:

The International Bowhunting Organization has set particular computations that help you know how to calculate arrow speed for various bow types. These include:

  • Draw weight that should be approximately 70 lb
  • A 30 inches long the length of arrow
  • The weight of the arrow that should be at least 350 grains

Here one thing matters that is nothing but the weight of the arrow itself. It affects the speed of the arrow. The more the weight of the arrow, the more the speed will be and vice versa. And to check how speedily a particular arrow will move with its weight, you may subject to this free arrow weight calculator to perform immediate calculations.

Principles of Archery:

The following rules allow you to adjust your arrow speed as per the International Bowhunting Organization:

These include:

Draw Length:

  • If the draw length of the arrow is under or equal to thirty inches (30”), then minus 10 feet per second for every inch from the International Bowhunting Organisation value.
  • Likewise, if the length of the arrow exceeds thirty inches (30”), simply add the 10 ft/sec to the IBO value for each increasing inch.

Arrow Weight:

  • For every successive increase of 3 grains of total arrow weight, minus 1 ft/s from the IBO value considering the weight is being multiplied by 5.
  • Likewise, subtract 1 ft/s from the IBO value for each increment up to 3 grains in the additional weight of the bowstring. You can perform these calculations by using this free arrow weight calculator that will automatically minus all the highlighted values and provide you with most optimal outputs.

Arrow Speed Formula:

You can determine the speed of the arrow along with other crucial parameters by using the following arrow speed equation:

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


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

IBO = Speed of the arrow according to the IBO specifications

L = Draw length measured in inches

W = Additional weight that is increased for a bowstring

A = Weight of arrow in grains

D = Weight of draw in pounds

All of these entities affect the speed of the arrow that can instantly be figured out by employing the online archery kinetic energy calculator.

How Archery Arrow Speed Calculator Works?

Let’s go through the guide below that highlights what parameters you need to calculate arrow speed instantly with the help of the free archery speed calculator.


  • In first couple of fields, enter Bow IBO rating and Draw Length of the bow
  • Similarly, put in the values of peak draw weight and arrow weight in the respective fields
  • At last, mention the additional weight to be put on string if any
  • After you are done, hit the calculate button


The free bow speed calculator determines:

  • Arrow speed
  • Momentum of the arrow
  • Kinetic energy of the arrow

Moreover, you can also calculate the kinetic and potential energies of any moving object with the assistance of our free to use kinetic energy calculator and potential energy calculator.


What is my arrow speed?

Well, it’s very simple. What you need to do is calculate the distance among two sets of speed arrows being shot from respective distances of 20 and 40 yards. With the assistance of the calculations, you would be able to estimate your arrow speed, but this calculation is not so accurate. While for more correct estimations, we refer you to make use of this archery arrow speed calculator that is absolutely for free.

How fast does a 70 lb bow shoot?

A 70 lb bow will shoot an arrow with an approximate velocity of about 270 feet per second (FPS).

Is 315 fps good for a bow?

On a normal basis, the speed of about 10 points is sufficient to shoot an arrow. And when the speed exceeds and reaches up to the maximum of 315 fps, it helps the arrow to attain consistency while moving with great speed.

What is a good arrow speed for deer hunting?

As far as the most correct estimations are related, archery experts do claim that a minimum speed of 260-270 fps would be sufficient to let the deer hunt successfully.

What is the fastest hunting bow?

According to the latest study, the maximum speed of the bow as per the International standard being recorded is 370 fps. You can also determine it by utilising our free arrow fps calculator archery.

What is the quietest bow?

Hoyt VorTec I is the world ‘s fastest bow.

What is the best bow brand?

8 of the best bow making brands worldwide include:

  • Bear Archery
  • PSE Archery
  • Elite Archery
  • Bowtech Archery
  • Mathews Archery
  • Hoyt Archery
  • Quest Bowhunting
  • Prime Archery

Moreover, the bows made by all of these brands let the speed arrows be shot at various velocities that could instantly be calculated by this arrow speed calculator.

What is a flagship bow?

A leader bow should feature the most sizzling patterns and most recent developments in the business. They’re a bow producer’s maximum effort of the year. In the event that you could do without your lead bow, then you presumably could do without current toxophilism.


The concept of arrow speed is quite related to the physical parameters like momentum, the angle of projection, speed and velocity. And altering one of these may change the the speed and directional angle of the arrow being shot by a particular bow. That is why we have developed this free arrow speed calculator so as to determine the speed of any arrow being shot, no matter how external parameters affect it anyway.
