F.O.C. Calculator

F.O.C Calculator

This is the overall length of the arrow measured from the throat of the nock to the end of the shaft.
This is where the arrow balances. Mark the point and measure from the throat of the nock.

F.O.C. is the percentage of the arrow’s total weight that is located in the
front half of the arrow. Higher F.O.C., within limits, can improve
performance in cross-wind conditions. Optimal F.O.C. is important for
target and bow hunting shooters involved in longer distances, especially
over 50 yards.

Optimal Target FOC Range:
For Target Archery, an optimal F.O.C. range is 7 -15% indoors and 10-15%
outdoors for up to 100 yards.

Optimal Bow Hunting F.O.C. Range:
For Bow Hunting, an optimal F.O.C. Range is 10 -15%.
