Unlock your arrow's full potential with our free Arrow FOC Calculator. Accurately determine your Front of Center percentage for improved arrow flight stability, enhanced accuracy, and better penetration. A critical tool for competitive archers and hunters seeking peak performance and a perfectly tuned setup.
Formula:
The Front of Center (FOC) percentage is calculated using the following formula:
FOC (%) = ((Balance Point - Physical Center) / Total Arrow Length) × 100
Where:
- Total Arrow Length (L): Measured from the deepest part of the nock groove to the tip of the broadhead or field point.
- Balance Point (B): The distance from the deepest part of the nock groove to the arrow's balance point.
- Physical Center (C): Half of the Total Arrow Length (L / 2).
This calculator simplifies the process by taking your arrow's total length and balance point to provide an accurate FOC percentage.
