How long you can afford to job hunt is your liquid savings divided by what you actually spend each month while searching, and that second number is almost never your current spending. Work the runway out with the wrong denominator and you will think you have eight months when you have five.
The gap matters because the runway decides the outcome. A search with four months of money behind it takes the first acceptable offer. A search with ten takes the right one, and the difference between those two offers is usually worth more than the savings themselves.

Your spending changes the day you stop working
Four lines move, and they do not move in the same direction.
Work costs stop. Commuting, parking, lunches bought rather than made, coffee, clothes for an office, and in some households a portion of childcare. For a commuting household this is commonly $300 to $500 a month.
Health cover starts. The premium your employer was paying without showing you becomes yours, and it is the largest single change in the list.
Job search costs appear. Small but real: a subscription or two, a course, certification fees, interview travel, and printing. Budget $50 a month and treat anything above it as an investment decision rather than a running cost.
Everything else stays. Rent or mortgage, utilities, insurance, food and debt payments are indifferent to your employment status, and they are the bulk of the number.
The net of those first three is frequently close to zero, which is why "I will just cut back" is a weaker plan than it sounds. The money is in the fourth line and the fourth line does not cut.
Health cover is the line that appears from nowhere
Two routes exist and they are priced completely differently.
COBRA continues the plan you already have, for up to 18 months. You pay 102% of the full premium: everything the employer was paying, plus a 2% administration fee. For a family that is frequently $1,500 to $2,200 a month, and it is the same cover you had yesterday at roughly five times what it appeared to cost.
A marketplace plan is priced on your household income for the year, not on your savings. A year with several months of no salary is a year with a low income, and the premium tax credit is calculated against that. The same family that would pay $1,900 for COBRA often pays a few hundred for a comparable marketplace plan, because the subsidy is doing the work the employer used to do.
For most people leaving a job with no income lined up, the marketplace is cheaper by a wide margin and COBRA is worth its price in one situation: you are mid-treatment and changing plans would change your doctors. The subsidy calculation, and the income level where it disappears, is in what health cover costs before 65.
Unemployment replaces part of the income, unless you quit
Benefits replace a fraction of prior wages, subject to a weekly maximum the state sets. The formulas differ everywhere, and so do the maximums, which run from a couple of hundred dollars a week in the lowest states to over a thousand in the highest. Look up your own state's maximum rather than assuming a national figure, because the spread is the largest variable in this calculation.
Benefits are taxable income, and nothing is withheld unless you file a Form W-4V and elect a flat 10%. Skipping that turns six months of benefits into a bill the following April, which is covered in how severance, unemployment and your 401(k) are taxed.
And in every state, quitting without good cause disqualifies you. What counts as good cause is set by state law and the definitions genuinely differ: some states limit it to job-related reasons such as unsafe conditions, while others recognise illness, a spouse's relocation, caring for a family member, domestic violence, a hostile workplace, or a large unilateral change to your schedule or pay. Leaving one job for another usually does not disqualify you at all.
If you are considering resigning without something lined up, answer that eligibility question before the resignation rather than after, because it is the single largest line in your runway and it is decided by the manner of your leaving.
How to work out your runway
Take your liquid savings, meaning cash and taxable investments you could sell this week. Not the 401(k), which costs about a third to reach early, and not the house.
Then build the monthly burn from your actual current spending rather than a budget.
| Line | Employed | Searching, eligible for benefits | Searching, resigned |
|---|---|---|---|
| Household spending | $6,000 | $6,000 | $6,000 |
| Work costs that stop | — | −$400 | −$400 |
| Health cover | $0 | $380 | $380 |
| Job search costs | — | $50 | $50 |
| Total out | $6,000 | $6,030 | $6,030 |
| Benefits, after 10% withholding | — | $2,145 | $0 |
| Net monthly burn | — | $3,885 | $6,030 |
On $30,000 of liquid savings that is 7.7 months with benefits and 5.0 months without. Note what the spending line did: cutting $400 of commuting and adding $380 of health cover and $50 of search costs left the household spending $30 a month more than while employed, before a single benefit payment.
Unemployment runs out before your savings do
The 7.7 months above is wrong, and it is wrong in the direction that hurts.
Most states pay benefits for 26 weeks, and several pay fewer. Once they stop, the burn jumps back to the full $6,030. Running the same $30,000 through that:
| Period | Monthly burn | Spent | Left |
|---|---|---|---|
| Months 1 to 6, benefits running | $3,885 | $23,310 | $6,690 |
| Month 7 onwards, benefits stopped | $6,030 | — | — |
| Runway | — | — | 7.1 months |
Seven point one, not seven point seven. The difference is small here and grows with the size of the benefit: the more of your burn benefits are covering, the harder the cliff at week 26 hits. Anybody whose runway calculation runs past six months needs to model that step rather than a flat rate.
Quitting costs about a third of your runway
Five months against seven. Same savings, same spending, same house, and the only difference is whether the separation qualified for benefits.
Set against the median job search of 108 days, five months is enough for a typical search and nothing more. It leaves no room for the search that goes badly, and it puts you in the position of negotiating an offer you cannot walk away from, which is the position that costs the most money over the following three years.
None of that argues for staying in a job that is doing you harm. It argues for the resignation being a decision with a number attached, and for finding out whether your state's good cause rules cover your situation before you hand in a letter rather than after.
Half of job searches run past three months
The median search runs 108 days from first application to accepted offer, which means half take longer. A runway of four months covers the median and fails the half of searches that miss it.
Rates are the useful way to plan this rather than hope. At the observed per-application interview rates, a tailored application converts at about one interview per 24 and a generic one at about one per 48, and the applications have to happen before the interviews that produce the offer. How many applications it takes to get an interview sets out where those numbers come from and what moves them.
The practical implication for the runway: plan for the 75th percentile rather than the median. If your runway covers the median exactly, you have built a plan that fails half the time.
How to make a short runway longer
Move the health line first. It is the largest controllable number in the calculation, and the gap between COBRA and a subsidised marketplace plan is frequently over $1,000 a month. On the table above, swapping the $380 marketplace premium for a $1,900 COBRA premium takes the runway from 7.1 months to 5.6, and the savings run out before the benefits do.
Take part-time or contract income early, not late. Income at month two extends the runway far more than the same income at month six, because it is not being spent against a balance that has already fallen. It also usually reduces benefits rather than ending them, since most states taper rather than cut off, though the rules differ. Ways to earn from home covers what is realistic to start quickly.
Pause the savings rate, not the spending. If you were putting money into a taxable brokerage account each month, stopping that is free. Cutting the grocery budget is not free, because it costs attention you need for the search.
Leave the retirement account alone. A withdrawal before 59½ is ordinary income plus a 10% penalty, and taking it in a year that also holds severance stacks it into your highest bracket. It is the most expensive money in the calculation and it is the easiest to reach.
Know what the job actually paid. A role that returned $34 an hour after commuting and unpaid overtime is a different thing to replace than one that paid $52. The real hourly wage calculation changes which offers are worth waiting for.
The two 60-day windows after you lose coverage
Losing job-based cover starts two clocks at once, and they run in parallel rather than in sequence.
COBRA gives you 60 days to elect, counted from the later of the day cover ends or the day the election notice reaches you. Cover is retroactive to the day it lapsed, so electing on day 55 backdates to day one. That retroactivity is the useful part: you can leave the decision open, and only elect if something happens that needs covering.
The marketplace gives you 60 days from the loss of cover to enrol outside the ordinary open enrolment window.
The trap is in the order. Electing COBRA and then cancelling it part way through does not generally reopen the marketplace window, because voluntarily dropping coverage is not the same qualifying event as exhausting it. Somebody who takes COBRA in month one and finds it unaffordable in month three can be left waiting for open enrolment. Check your own situation on healthcare.gov before choosing, since this is the decision in the whole calculation that is hardest to reverse.
Frequently asked questions
How much savings do I need before quitting my job?
Enough to cover your searching burn for longer than the median search, which runs 108 days. Because quitting usually disqualifies you from unemployment benefits, the burn is your full monthly spending plus the health premium, with no offsetting income. On a $6,000 household that is roughly $36,000 for six months, against about $23,000 for the same six months if you had been laid off instead.
How do I calculate my job search runway?
Liquid savings divided by net monthly burn. Net burn is your current spending, minus work costs that stop, plus the health premium and search costs, minus any unemployment benefit after tax. Model the benefit stopping at 26 weeks rather than assuming it runs to the end.
Can I get unemployment if I quit my job?
Only with good cause as your state defines it. Every state disqualifies a voluntary quit without it, and the definitions vary: some cover only job-related reasons, others include illness, a spouse's relocation, caring for a relative, domestic violence or a large unilateral change to your pay or hours. Leaving for another job usually does not disqualify you.
Is COBRA or a marketplace plan cheaper while unemployed?
Usually the marketplace, by a wide margin. COBRA charges 102% of the full premium with no subsidy, while a marketplace plan is priced on your income for the year, and a year with several months of no salary produces a large premium tax credit. COBRA wins when continuity of treatment matters more than the price.
How long do unemployment benefits last?
Most states pay for up to 26 weeks, with several paying fewer. Any runway longer than six months has to account for the burn rising when benefits stop, which is the step most calculations miss.
Are unemployment benefits taxed?
Federally, yes, and nothing is withheld unless you file a Form W-4V and elect a flat 10%. State treatment varies: some tax benefits as ordinary income, some exempt them entirely.
Should I use my 401(k) to fund a job search?
It is the most expensive money you have. Income tax plus the 10% early withdrawal penalty takes about a third before state tax, and a withdrawal in a year that also contains severance is taxed at your highest marginal rate. Exhaust cash, taxable investments and a reduced savings rate first.
