The working Stock-Based Compensation tool will appear here once developed. No calculation logic is implemented yet.
Purpose
Estimate the grant-date fair value of equity awards using the Black-Scholes model and illustrate how the resulting compensation cost is attributed over the requisite service period under ASC 718.
Intended inputs
- Grant details: number of options, exercise price, and grant date
- Underlying share price at grant date
- Expected term, expected volatility, and risk-free interest rate
- Expected dividend yield
- Vesting schedule and estimated forfeiture assumptions
Intended outputs
- Estimated grant-date fair value per option and in aggregate
- Compensation cost attribution schedule over the service period
- Sensitivity of fair value to key assumptions
- Summary of inputs and the model applied

Assumptions and limitations
- Black-Scholes is most appropriate for service-based awards without complex features.
- Volatility, expected term, and forfeiture assumptions require judgment and support.
- Awards with market or performance conditions may require alternative valuation models.
- Estimates are illustrative and must be validated against grant documentation.
