An emergency fund is general-purpose by design, but a planned or anticipated job change has its own specific financial checklist — one that's far easier to work through before you give notice (or before a layoff happens) than while you're already navigating the transition itself.

Health insurance: the piece people forget until it's urgent

Employer-sponsored health coverage typically ends on your last day or the end of that month, and understanding your bridge options before that date matters. COBRA allows continuing your employer's exact plan temporarily, usually at a meaningfully higher cost since the employer subsidy disappears. A marketplace plan or a spouse's employer plan are often worth comparing before assuming COBRA is the only option — a job change or loss is generally treated as a qualifying life event, opening a specific enrollment window that has its own deadline.

Timing large expenses around insurance changes

If you have a planned medical procedure, a prescription refill, or a dental visit that can reasonably be scheduled before your current coverage ends, doing so avoids a gap-coverage complication. This is a logistics question worth answering weeks in advance, not the week your coverage actually changes.

A widely cited rule of thumb is three to six months of essential expenses in savings — but the honest number depends heavily on how quickly you could realistically expect to replace your income in your specific field.

The cash cushion, sized to your situation

A general emergency fund guideline of three to six months of essential expenses is a reasonable starting point, but a job change adds specific variables: how quickly your industry typically hires, whether you're relocating, and whether the new role has a probationary period before benefits kick in. Someone in a fast-hiring field might reasonably lean toward the lower end; someone in a specialized or slow-hiring field might want more.

Before you give notice, check

Try thisBefore giving notice, write out your specific "departure math": last paycheck date, PTO payout (if any), health coverage end date, and your monthly essential expenses. That single page tells you exactly how many weeks of true cushion you're working with.

None of this changes whether a job change is the right move — it simply removes the financial guesswork from the transition, so a career decision doesn't get complicated by an insurance gap or a cash flow surprise that a little advance planning would have caught.
