One of the most common questions I get from founders, early employees, and even investors is:

👉 How do shares actually vest over time, and what happens if there’s an exit or acceleration clause?

Equity is one of the most powerful tools in the startup world. It’s how companies attract and retain talent, align incentives, and share in long-term success. But the details can get complicated, cliffs, monthly vesting, single vs. double-trigger acceleration, and how these scenarios play out in real life.

That’s why I built a Vesting & Acceleration Calculator that you can start using today.

🧩 Why Vesting Matters

Vesting ensures that equity is earned over time, not granted all at once. For example:

A standard vesting schedule might be 4 years with a 1-year cliff.
That means you earn nothing in year 1, but at the end of month 12, you vest 25%.
After that, the remaining 75% vests in equal monthly installments over the next 36 months.

This structure incentivizes long-term commitment while protecting the company from handing out equity to people who leave early.

⚡ Where Acceleration Comes In

Acceleration clauses kick in when a major event happens, most commonly a change of control (acquisition) or a termination.

Single-trigger acceleration: Shares accelerate upon a change of control.
Double-trigger acceleration: Shares accelerate only if there’s a change of control and the person is terminated afterwards.

Example: If you’re an early employee and the company is acquired, acceleration can mean the difference between owning 25% of your grant or suddenly being fully vested.

🛠️ The Calculator

The tool I created lets you:

See a full monthly vesting schedule
Track total vested vs. remaining shares
Add acceleration scenarios (single or double trigger)
Model different percentages and event dates

This way, whether you’re a founder negotiating terms, an employee reviewing your stock options, or an investor modeling a cap table, you can get instant clarity.

💡 Final Thought

Equity isn’t just numbers in a contract, it’s your stake in the journey. The more clearly you understand vesting and acceleration, the more confidently you can negotiate, plan, and build.

If you know a founder who could benefit from this, share it with them!
