How to Use the Share Incentive Plan Calculator
This calculator estimates the total value of a share grant that vests over time, assuming shares grow at a constant annual rate.
- Enter Grant Size – The total number of shares you are granted (e.g., 1000).
- Enter Current Share Price – The price per share today in dollars (e.g., 50.00).
- Enter Annual Growth Rate – The expected yearly price increase as a percentage (e.g., 10 for 10%).
- Enter Vesting Period – The number of years over which shares vest (must be at least 1).
- Click "Calculate" – The tool shows the total value and a year-by-year breakdown.
Key details:
- Shares vest equally each year (e.g., 4-year vesting = 25% per year).
- Each year’s shares are valued at the projected price for that year.
- All inputs must be positive numbers. Zero grant size or price gives a $0 result.
