Vesting Schedule Calculator (Cliff and Monthly Vesting)
Enter a grant, the vesting period, the cliff, and how often shares vest to see how many have vested after any number of months, what arrives at the cliff, each later vesting, and the full schedule as a table and a chart.
Vesting Schedule Calculator (Cliff and Monthly Vesting): Shares vest in equal parts over the period, but none before the cliff. With 48,000 options over 48 months and a one-year cliff, 12,000 vest at month 12, then 1,000 every month; after 18 months 18,000 have vested, 37.5%. Fractions are rounded down until the last vesting, which makes up the total. Runs 100% locally in your browser with zero server file uploads.

Shares vest in equal parts over the period, but nothing vests before the cliff: on the cliff date, everything that would have vested by then arrives at once, then the rest vests every month, quarter, or year. Four years with a one-year cliff is the common pattern for startup employees. Fractions are rounded down until the last vesting, which makes up the total.
Common schedules
Four years with a one-year cliff and monthly vesting is the most common for startup employees; some companies vest quarterly, and RSUs at large companies often vest every quarter or every six months. Back-weighted schedules vest more in later years.
Dates
To find the calendar date of a cliff or the end of vesting, count forward from your start date with add days to a date.
How to use it

Frequently asked questions
What is a cliff?
A period at the start, usually a year, during which nothing vests; if you leave before it, you get nothing, and on the cliff date you receive everything that has built up.
What happens if I leave?
Unvested shares or options are usually forfeited; vested options must often be exercised within a set time, commonly 90 days, so check your grant agreement.
What is acceleration?
A clause that vests some or all of the remaining shares early, usually when the company is sold (single trigger) or when you are let go after a sale (double trigger).
