Model your full equity stack — RSUs, stock options, ESPP, restricted stock, and SAR/phantom/PSU grants — and project vested, unvested, and after-tax value year by year.
Every RSU, option, ESPP, restricted stock, and SAR or PSU grant is projected on one price path and aggregated into a year-by-year timeline of vested value, unvested value, and after-tax cash.
Expected price growth, the vesting schedule and cliff, your tax profile, and option strike or settlement type usually change the projected after-tax outcome far more than any single grant size.
