Frequently Asked Questions
A cliff is a minimum period (commonly 12 months) before ANY shares vest, even though vesting is technically accruing from day one. Before the cliff, this tool shows 0 vested shares regardless of months elapsed; right after the cliff, a lump sum for that period typically vests at once.
4 years total vesting with a 1-year cliff is the most common default in the US and increasingly in India — this tool defaults to those figures but lets you enter your own.
This calculator computes vesting linearly by month once past the cliff (total shares × months elapsed ÷ total vesting months) — actual grants sometimes vest in monthly, quarterly, or annual installments, which can create small differences from a purely linear calculation.
Vesting caps at 100% — entering more months elapsed than the total vesting period won't show more than the full grant as vested.
