How the vesting schedule is calculated

Vested options = grant size × completed vesting months ÷ total vesting months. Before the cliff, no options vest. On the cliff date, the cliff portion vests; later vesting follows the selected monthly, quarterly, or yearly frequency.

This is a simplified planning estimate. Actual grant agreements may use different rounding, acceleration, termination, leave, or change-of-control rules. Your signed plan documents control.
