Schedule

A calendar model of a vesting schedule — not tax, legal or investment advice. The plan document always wins.

How It Works

The generator builds a plain monthly schedule from four numbers: grant size, start date, cliff and total vesting months. All arithmetic is UTC calendar math with month increments and day-of-month clamping, so the same inputs always produce the same dates.

The cliff
A cliff means nothing vests before it. In the classic cliff-then-linear pattern, at the cliff date you receive the whole accrued slice at once (cliff months ÷ total months of the grant), and normal monthly vesting resumes afterward. With a 12-month cliff on a 24-month grant, that is 50% on the cliff date and 1/24 of the grant every month after. Before the cliff the unlocked amount is 0 — the calculator flags that state explicitly.
Monthly accrual, floored
Vesting is credited only for milestones fully reached: unlocked count = floor(months elapsed) × monthly increment, capped at the grant. Halfway through a month, that month is not yours yet. This is a deliberate, conservative rounding rule — plans that accrue daily will show you slightly more than this page does between milestones.
The typical pattern
Crypto and startup grants usually follow a "4-year / 1-year cliff" or "2-year monthly" shape: total months set the denominator, the cliff the first big event, and monthly vesting everything in between. One-time vesting (a single event at the end of the period) models advisor tokens and simple milestone unlocks.

Frequently Asked Questions

Will I owe tax when tokens vest?

It depends entirely on your jurisdiction, your entity's structure and how the grant is classified (RSU, options, token warrant, restricted property), and the rules change often. In several regimes, vesting is a taxable event even though you cannot sell yet — which can mean owing tax before you have cash. This page does the calendar arithmetic only; get a tax professional in your jurisdiction to tell you what applies.

Does leaving the company stop vesting?

Usually unvested grants stop accruing at termination, and many plans forfeit them; some have extended exercise windows or partial-vest protections, and founder or advisor agreements often differ. The plan document always wins over any generic schedule — this calculator models the math of a schedule, not the terms of your agreement.

How exact are the dates for past grants?

The math is pure calendar arithmetic in UTC: month increments with day-of-month clamping (vesting on the 31st of a month falls to the month's last day). It is deliberately timezone-blind, so if your grant agreement vests at a specific local hour, events on the boundary day can differ by a day. Double-check anniversary and cliff dates against the grant document.

What does the floor rounding rule mean in practice?

You are credited only for vesting months you have fully reached: on the day before your 12th monthly milestone, unlocked stays at 11/24, not 11.5/24. Real plans can define fractions differently (some accrue daily), so treat the count as a conservative estimate and confirm the accrual convention in your plan.

No. The whole schedule is computed in your browser with plain JavaScript. Your grant size, dates and results never leave your device and are not stored or transmitted anywhere.
