You can use these calculators to calculate arrow front of center (FOC), bow speed, dynamic shooting efficiency, and more..

**Handicap Calculator
**

calculate handicap.

**Archery Handicap Table Calculator
**

This calculator uses the standard formulas which were used by Archery Australia from (at least) the 1980s through to January 2011

**Arrow Front of Center (FOC) Calculator
**

Archery calculators for Front of Center (FOC), Kinetic Energy, Momentum and Estimate Bow/Arrow Speed.

**Bow Speed Calculator (Estimate from IBO/ATA)
**

Archery calculators for Front of Center (FOC), Kinetic Energy, Momentum and Estimate Bow/Arrow Speed.

**Dynamic Efficiency Calculator
**

Use this to calculate a bow's dynamic shooting efficiency with any arrow. (Useful in studying how arrow weight affects performance.)

**Kinetic Energy and Momentum Calculator
**

Archery calculators for Front of Center (FOC), Kinetic Energy, Momentum and Estimate Bow/Arrow Speed.

**Launch Energy and Momentum Calculator
**

Use this to calculate the launch energy and momentum of any arrow when its weight and launch speed are known. (Useful in studying how weight and speed affect the arrow's ability to bore through the air and into a target.)

**Launch Speed Calculator
**

Use this to calculate the launch speed of any arrow when you know the weights and launch speeds of two other arrows shot from the same bow. (Useful when trying to find realistic speeds to use in the other calculators.)
