How to Use This Calculator
- Enter the Current Stand Volume in MBF (thousand board feet) and the Current Stand Age in years.
- Enter the Site Index reflecting soil quality and growth potential for the species.
- Enter your Projection Period in years to forecast volume at a future date.
- Review Projected Volume and Volume Growth to plan harvest timing and timber sale revenue.
- Check Optimal Rotation Age and Periodic Annual Increment (PAI) to identify the most productive cutting cycle.
