Leaving a Job Before You Vest: How to Price What You'd Give Up

By Smart Budget Sheets November 10, 2026
How to price unvested 401(k) or pension money before changing jobs.

If you are close to a vesting date, the question is not only “should I stay?” but “how much is staying worth?” You can usually put a number on it.

What vests and what doesn’t

  • Your own contributions to a 401(k) or similar plan are always 100% yours.
  • Employer 401(k) contributions can vest on a cliff (up to 3 years, then 100%) or a graded schedule (fully vested by year 6 at the latest).
  • Traditional pensions (defined benefit) can use a 5-year cliff or a graded schedule finishing by year 7.

Get the numbers in writing

  1. Ask HR or the plan administrator for your vested balance today and what it becomes on the vesting date.
  2. For a pension, ask for an estimate of the monthly benefit at normal retirement age if you leave after vesting.
  3. Check your summary plan description for the exact schedule and how a “year of service” is counted (often 1,000 hours in a plan year).

Compare it with the new offer

Example: $9,000 of unvested employer contributions, vesting in 9 months. A new job paying $6,000 more a year plus a 4% match on $70,000 ($2,800 a year) would take a little over a year to make up the $9,000. If the new offer is larger, or the role matters for your career, leaving can still be the better move; you just make the choice knowing the cost.

Things people miss

  • Some employers will cover forfeited amounts with a signing bonus if you ask and show the numbers.
  • A pension benefit that is vested stays yours even if you leave; keep the paperwork and update your address with the plan.
