RSU Vesting Calculator

How to use

1. 1Enter the total grant size in shares and the grant date. Pick a preset for a typical 4-year monthly or quarterly schedule if you want to start fast.
2. 2Set the total vesting length and cliff. The defaults match most modern RSU grants: 48 months total with a 12-month cliff. Use 0 cliff for grants that vest immediately.
3. 3Pick the post-cliff cadence (monthly, quarterly, semi-annual, or annual). Quarterly is the most common at large public companies; monthly is typical for startups.
4. 4Optionally add a share price and currency to see the pre-tax value of each vest, the value of what is vested today, and the value of what is still unvested.
5. 5Use Fractional share handling to floor each tranche to whole shares (the typical real-world behavior), round to the nearest share, or show exact decimals.
6. 6Change Vested as of to simulate any past or future date and watch the schedule, vested shares, and next vest event update.
7. 7Use Copy summary for a paste-ready overview, or Copy CSV schedule to drop the full table into a spreadsheet or doc.

About this tool

RSU Vesting Calculator builds the full vesting schedule for a restricted stock unit grant and shows what is vested today, what is still unvested, and when the next tranche lands. Enter the total grant size in shares, the grant date, the total vesting length in months (48 is the most common, equal to a 4-year grant), and the cliff in months (12 is the most common, equal to a 1-year cliff before any shares vest). Choose how the remaining shares vest after the cliff: monthly (the typical startup grant), quarterly (most large public-company RSU plans), semi-annual, or annual. Optionally add a share price and the calculator shows the dollar value of each tranche, the value of what is vested today, and the value of what is still unvested. The tool handles fractional shares the same way real employer plans usually do: it floors each tranche to whole shares and rolls the leftover into the final vest so the cumulative total still matches the grant exactly. You can switch to nearest-share rounding or to exact decimals to compare. A vest date in the past is marked as already vested, a Cliff badge highlights the first vest after the cliff, and an As-of date control lets you simulate a future date so you can answer questions like "how much of my grant will be vested before my one-year work anniversary" or "how many shares vest before the next earnings call." The schedule table shows the tranche number, vest date, shares vested that period, cumulative shares, cumulative percent, and (when a share price is set) the per-tranche and cumulative pre-tax value. Useful for negotiating a job offer (compare an A side with $200K cash + 4-year RSU grant vs a B side with $230K cash + smaller grant), reading an existing grant agreement, planning a refresher grant that stacks on top of an existing one, modeling what happens to your equity if you leave before the cliff, building a personal compensation model, or visualizing how much value sits at risk on each future vest date. Everything runs in your browser, so the grant size, dates, and share price you type are never uploaded. This tool models a standard time-based RSU schedule. It does not account for income tax, sell-to-cover withholding, performance conditions, or company-specific clawback rules. Read your grant agreement for the exact terms that apply to you.
