Equity Compensation Calculator
What RSUs or stock options vesting over a schedule are worth at a share price you enter: vested and unvested shares by a date, their value, the next vesting date and a vesting table, with a cliff and monthly, quarterly or yearly vesting.

How it's calculated
Vesting dates: the cliff, then every month, quarter or year after it, up to the end of the period Vested by month m = shares × m ÷ vesting months, rounded down (all of them at the end) RSU value = shares × share price Option value = shares × max(0, share price − strike price)
Restricted stock units (RSUs) and stock options are usually earned over a vesting schedule: often nothing for a first period called the cliff, then a slice every month, quarter or year until the grant is complete. This calculator lays out every vesting date from your start date, cliff and period, and shows how many shares or options have vested by the date you choose, how many are still to come, and what each part is worth at the share price you enter. An RSU is worth the share price; an option is worth only the amount by which the share price exceeds its exercise price, and never less than zero. The vesting table shows each date, or each year for long monthly schedules.

About the Equity Compensation calculator
This equity compensation calculator shows what a grant of restricted stock units (RSUs) or stock options is worth as it vests. Enter the number granted, the vesting start date, the cliff, the total vesting period and whether shares vest monthly, quarterly or yearly after the cliff, then a share price and the date you want to value the grant on. It lists every vesting date, counts the vested and unvested shares by your date, and values them: an RSU at the share price, and an option at the share price minus the exercise price, never below zero. It also gives the next vesting date. Employees use it to understand an offer letter, plan around a vesting date or see what they would leave behind by changing jobs. The share price is yours to enter, and every step is shown. To weigh a grant within a full package, try the job offer comparison calculator.
How to use it
- Choose the “Grant type”: “RSUs (shares)” or “Stock options”, and enter the “Shares or options granted”.
- Enter the “Share price” to value the grant at, and for options the “Exercise (strike) price”.
- Set the “Vesting start date”, the “Cliff” and the “Total vesting period” in months, and how it vests “After the cliff”.
- Pick the “Value as of” date to see what has vested by then, and read the vesting table in the steps.
Worked example
You hold 6,000 options with an exercise price of 6, vesting over 48 months from 1 March 2025 with a 12-month cliff and quarterly vesting after it. Each option is worth 18 − 6 = 12 at a share price of 18. On 1 March 2026, 1,500 options vest at the cliff, then 375 every quarter. By 28 October 2026, 2,250 have vested, worth 27,000, and 3,750 are unvested, worth 45,000. The next 375 vest on 1 December 2026, and the whole grant is worth 72,000 at this price.

Questions people ask
How do I calculate how many RSUs have vested?
Count the months from the vesting start date to your date. If you are past the cliff, the vested share is roughly the months passed ÷ the total vesting months, counted only at the vesting dates. This calculator rounds down to whole shares until the final date, when all of them vest.
What is a vesting cliff?
A cliff is a first period during which nothing vests. When it ends, everything earned so far vests at once: with a 12-month cliff on a 48-month schedule, a quarter of the grant vests on the first anniversary.
How is a stock option valued differently from an RSU?
An RSU is worth the full share price, because you receive the share. An option is the right to buy a share at the exercise price, so it is worth the share price minus the exercise price; if the share price is below the exercise price, the option is worth nothing to exercise today.
What is a common mistake when valuing equity compensation?
Treating the whole grant as money in hand. Unvested shares are usually lost if you leave, share prices move, and tax may be due on vesting or exercise, so the vested, after-tax value is often much lower than the headline figure.
Does the calculator include tax on RSUs or options?
No. When and how equity is taxed varies by country and by type of plan, and some plans add rules such as acceleration or different rounding. Check your grant agreement, and ask a tax adviser or financial professional before you make decisions.
