Use the arrow efficiency calculator to estimate the most efficient arrow for your specific bow set up.

Arrow Efficiency Calculator – Instructions

  1. Select Preferred Arrow Efficiency
    • Max Speed: IBO arrow (5 grains/per pound of draw weight).
    • Max Efficiency: arrow ~10-15% over IBO (5.5 grains/per pound of draw weight).
    • Max Energy: arrow ~20% over IBO (6 grains/per pound of draw weight).
  2. Chronograph Arrow Speed
    • Shoot three arrows and use the average of the three shots.
  3. Enter Data Below for Results
    • Enter speed and arrow weight data into the calculator.
  4. View Results*
    • Dark Blue: Optimal arrow weight.
    • Light Blue: Range of efficient arrow weights.
    • Red: Highlights specific speeds in fps and MAX energy (KE and M).
