Vesting: Why Leaving 11 Days Early Costs The Whole Match

I once came close to resigning eleven days before a vesting anniversary, and I only found out because I was in the benefits portal looking for something unrelated.

Eleven days.

Nobody would have told me. HR does not run an alert for this, your manager does not know your schedule, and the packet that explains it arrived on your first day when you were busy learning where the bathroom was.

Your money is always yours. Theirs is on a timer

Every dollar you contribute from your own paycheck is 100% yours from the second it leaves. That is not negotiable, not conditional, and not affected by how you leave or how badly.

The employer match is different. It is a contribution the company makes on your behalf, and most plans attach a vesting schedule to it, meaning you earn ownership of it over time. Whatever has not vested when you leave goes back to the plan.

Some plans vest the match immediately, particularly certain safe harbor designs. If yours does, none of this applies and you can stop reading. Find out which one you have.

Two shapes, and they behave completely differently

A cliff schedule pays nothing, then everything. Three years is the common shape: 0% at two years and eleven months, 100% the next day.

A graded schedule pays a slice each year, typically 20% a year over five years or 25% over four. You are always partly vested and you are never fully vested early.

Read the cliff column and the risk is obvious. At two years and eleven months you have $0 of a $12,000 match. One month later you have all of it, and there is nothing in between.

The graded column is gentler and it has its own trap, which is that people assume they are fully vested because they have been vesting for a while. At four years on a five year schedule you are leaving $2,400 behind.

What counts as a year

Not necessarily your hire anniversary. Plans are allowed to measure service in different ways, and some count plan years, some count hours worked in a year, some count from the start of the plan year you were hired in.

This is the one place where reading the actual document beats asking a colleague, because your colleague is confidently repeating whatever they were told in 2019.

The document is the summary plan description. Search it for the word vesting, or for employer contributions.

The situations where the schedule stops applying

Vesting rules have exits, and three of them come up often enough to know about.

If the plan is terminated, participants generally become fully vested. That can happen in an acquisition or a wind down, which means a company closing your division may hand you the match you had not earned yet.

Reaching the plan's normal retirement age, or in many plans becoming disabled or dying, also typically triggers full vesting regardless of years of service.

And if you leave and come back, prior service often counts toward the schedule. Not always, and the rules around breaks in service are fiddly, but do not assume a rehire resets you to zero without checking.

What I am and am not telling you

I am not telling you to stay in a job you hate for four months. Four months of a bad job is a real cost and it does not appear in any table.

I am telling you to know what those four months are worth before you decide. $7,000 is a real number, a start date is usually movable by a few weeks, and I did not know is not a reason.

Go find the vesting schedule before you write the resignation letter, not after. Then count the days, put the number next to the date, and make the call as a person holding both facts.
