The recruiter reached out on a Wednesday. Better role, better culture, base salary in the right range. The offer came two weeks later. She accepted.
Three months in, she learned her equity grant at the previous company had a four-year vesting schedule. She'd been there three years and two months. The fourth year's worth, roughly $40,000, was forfeited the day she gave notice. Her new health insurance had a 60-day waiting period. She paid two months of COBRA to bridge it.
Neither of those facts changed whether the move was right. But both of them should have been part of the decision.
Career decisions feel like professional decisions. A better title, a stronger team, work that fits better, a company with more runway. The financial dimension is present in salary negotiation. Most people do that part. But the rest of the picture tends to get examined after the fact, if at all. The unvested equity, the vesting cliff reset at the new company, the 401(k) match timing, the FSA balance that can't be transferred, the pension credit that required two more years: these don't show up in the offer letter. They show up in the rearview mirror.
First-generation earners are particularly exposed here. The salary negotiation happens. Most people know to do that part. The rest of the compensation picture is less legible, and the offer letter doesn't make it easier. The full cost of a transition rarely surfaces until after the decision is made.
What the Financial Scan Actually Covers
Sometimes those 30 minutes produce a reason to adjust timing. Sometimes they produce a reason to negotiate harder. The point is to surface the full cost of the transition before the decision is final, not after.
Four areas cover most of the exposure.
Unvested equity and vesting cliffs. What's still unvested at the current employer, and when does the next tranche vest? A month or two of patience can sometimes recover a meaningful amount. A cliff reset at the new employer, where many grants start vesting from scratch, means the first year at the new company carries real opportunity cost if the move doesn't work out.
Benefits gap. When does current coverage end, and when does new coverage begin? COBRA fills the gap but at full cost. A waiting period of up to 90 days at the new employer is common and rarely volunteered. The FSA balance is often forfeited mid-year: that's money already allocated from a tax-advantaged account that doesn't transfer.
401(k) match timing. Many employers have a vesting schedule on their match, not just on equity. Leaving before the match is fully vested means leaving part of the compensation behind. The new employer's match may not begin until after a waiting period.
Compensation structure differences. A lower base with a bonus component, commission, or equity can look equivalent to a higher base on paper. The timeline, certainty, and structure of variable compensation are worth mapping before the comparison is made.
What the Cost Should Trigger
Knowing the financial footprint of a transition isn't just information. It creates leverage. If the cost of leaving is meaningful, there are specific ways to respond before signing: request a delayed start date to capture a vesting tranche, negotiate a signing bonus that offsets forfeited compensation, ask for a guaranteed bonus in year one if variable pay resets, or align the transition timing with a benefits enrollment window. None of these are unusual asks in professional hiring. Most require only that the question gets raised.
The new employer will rarely surface these options unprompted. They don't need to. The candidate who knows to ask is in a different negotiation than the one who doesn't.
The Broader Point
Career mobility is a financial variable, not just a professional one. Each move has a financial footprint. Sometimes it's small. Sometimes, a vesting cliff, a pension credit, a benefits gap, it's significant enough to affect the net value of the decision.
A good offer compresses the decision window. The financial questions that would take 30 minutes to answer get crowded out by the pull of the move itself. That's the moment they matter most.

Frequently Asked Questions
What happens to my 401(k) if I leave before I'm fully vested in the employer match?
The contributions you made are always yours. The employer match follows a vesting schedule, typically cliff vesting (nothing until a set date, then all at once) or graded vesting (a percentage each year). If you leave before the match is fully vested, you forfeit the unvested portion. The schedule is in your plan documents and worth checking before giving notice.Can I negotiate the timing of a start date to protect unvested equity?
Yes, and it's more common than most people realize. If a vesting date is four to six weeks away, asking to delay a start date, or negotiating a signing bonus to offset the forfeited amount, is a reasonable ask, particularly for senior roles. The new employer may not volunteer this option, but they're generally aware the conversation can happen.What should I do with my 401(k) from a previous employer after I leave?
You have several options: leave it in the former employer's plan if the balance meets the threshold, roll it into your new employer's plan, or roll it into an IRA. Each has tradeoffs related to investment options, fees, creditor protection, and future flexibility. The right answer depends on the plan quality and your broader financial picture.How do I handle an FSA if I leave mid-year?
A healthcare FSA is generally forfeited when you leave employment, with limited exceptions. If you've already incurred eligible expenses up to the annual election amount, those can be reimbursed before your last day. Timing larger planned medical expenses before a known departure can help recover what you've already elected. For more detail on FSA rules, IRS Publication 969 covers healthcare flexible spending arrangements.Is it worth staying at a job I want to leave just to hit a vesting date?
Sometimes, briefly. If a vesting date is weeks away and the amount is meaningful, a short delay is often worth the math. If it's months away and the opportunity is time-sensitive, the calculus changes. The point isn't to stay indefinitely for financial reasons. It's to know the number so the decision is deliberate rather than accidental.Everyone deserves a plan for their future. Let's build one that reflects your values and priorities.
