Can I Afford to Quit My Job? The Two Numbers That Decide It

Most answers to this question give you one number. Take your liquid savings, divide by your monthly spending, and that is your runway. Six months is comfortable, three is tight, less than that is reckless.

That arithmetic is correct and it is half the calculation. It answers how long you can survive without income, which is the right question if you are quitting into nothing. If you are quitting into a change, and almost everyone asking this question is, then the number that actually decides it is the second one: the lowest salary the next role can pay and still leave you able to change your mind again.

Runway buys you time. Your floor salary decides whether you ever get that time back. This article gives you both, plus the three costs that vanish from your budget the day you resign because an employer has been quietly paying them for you.

The short answer: it takes two numbers

Write both of them down before you do anything else.

Number 1, your runway. Liquid savings divided by your monthly spending after you quit. Post-quit spending is not your current spending: some costs disappear, several appear, and the ones that appear are larger than people expect.

Number 2, your floor salary. The gross annual salary at which the new role covers your essential costs, covers the benefits you now buy yourself, and repays the savings you spent getting there over the following 2 years.

You can afford to quit when your runway covers a realistic search and the roles you are targeting pay above your floor. If only the first is true, you can afford to leave but not to stay gone. If only the second is true, you are affording the destination and not the journey, which usually means the sequence needs to change rather than the plan.

Your runway, and why 3 months is the wrong default

The 3-month rule is not wrong so much as it is a median dressed up as a rule. Here is the actual distribution of how long people are out of work.

Read those two figures together, because the gap between them is the whole point. The median is about 2.6 months, so a 3-month cushion genuinely covers the middle of the distribution. The mean is more than double the median, which only happens when the right-hand tail is heavy, and you can see the tail in the table: 27% of unemployed people had been out for 27 weeks or more.

So the 3-month rule works if your search runs to the median and fails about a quarter of the time. Three groups sit disproportionately in that tail, and if you are reading an article about affording to quit you are probably in at least one of them:

• You are senior. Fewer roles exist at your level, hiring committees are larger, and the process runs longer at every stage.
• Your function is narrow. A specialist search has fewer shots on goal than a generalist one.
• You are changing field rather than employer. Every application is being read by someone deciding whether your experience counts, which adds a persuasion step to every stage.

If two of those apply, budget from the tail. Six months of full post-quit burn is the honest floor for a mid-career switch, and the difference between the two figures is usually a few months of preparation rather than a different life.

One correction to the denominator, because it moves the answer more than people expect. Your post-quit monthly spending is not your current monthly spending. Commuting stops, and so does a category of spending that only exists because you are somewhere five days a week. Our commute cost calculator puts a number on the first part. Then add back what your employer stops paying, which is the next section, and use the total as the denominator. People who skip this step usually get their runway wrong in both directions at once.

Your floor salary, the number almost nobody calculates

Break-even is the wrong target, and it is the target nearly every guide implies. If the new role covers your costs exactly, you never rebuild the savings you spent getting into it. The change looks affordable on the day you accept and becomes a trap 18 months later, because if the new role turns out to be wrong you have no cushion left to make a second move. That is how a career change becomes a one-shot bet, and one-shot bets are why people stay in roles they have already outgrown.

Your floor is break-even plus repayment:

Floor salary = (essential annual spending + annual cost of benefits you now carry yourself + debt service + the runway you spent, divided by 2) ÷ (1 minus your effective tax rate)

The "divided by 2" is the part that matters. It rebuilds your cushion over 24 months, which keeps your next decision affordable. Set that term to zero and you have calculated break-even, which is a number that tells you what you can survive rather than what you can accept.

Now compare your floor against what the target roles pay. This is where most affordability advice stops being useful, because it treats the next salary as an unknown when it is published data. These are wage bands for roles that mid-career switchers move into most often, chosen because they price experience rather than credentials:

Annual wages from the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics program, May 2025 release. Half of workers in a role earn more than the median; the 25th to 75th percentile span shows how wide the role pays. To see where your current salary sits in your own occupation, use the free salary benchmark.

Two ways to read that table. If your floor sits below the 25th percentile of a role, that move is affordable even if the offer comes in weak. If your floor sits above the median, you are relying on an above-average offer in a field where you are unproven, which is a plan that needs a longer runway behind it. To place your current salary inside your own occupation first, the salary benchmark tool does that in a couple of minutes.

The three costs that leave your payslip and arrive in your budget

These are the costs an employer absorbs so completely that they never appear in your mental model of what your life costs. All three arrive at once.

1. Health coverage, which is the big one

In 2025 the average annual premium for employer-sponsored family coverage was $26,993, and the average covered worker contributed $6,850 of it. For single coverage the premium averaged $9,325 with a worker contribution of $1,440. Those figures come from the KFF 2025 Employer Health Benefits Survey, which surveys more than 1,800 employers.

You have been budgeting the $6,850. The market has been charging $26,993. Whether you continue the same plan through COBRA, buy on the marketplace, or join a partner's plan, some version of that gap enters your monthly burn, and it enters both calculations: it shortens your runway and it raises your floor salary. If you take one number from this article, take this one, because it is the single largest correction most people need to make.

2. Employer retirement contributions, including the money that is not yours yet

Two separate losses hide in this line. The obvious one is that employer contributions stop for every month you are out. The expensive one is vesting.

Employer contributions to a 401(k) vest on a schedule set by your plan document, and per the IRS rules on vesting a qualified plan can require up to 3 years of service for cliff vesting or up to 6 years on a graded schedule. Anything not yet vested is forfeited when you terminate employment. Your own contributions are always yours; the employer's may not be.

So before you pick a resignation date, find your vesting date. If you are 4 months from a cliff, those 4 months are worth whatever the unvested balance is, tax-advantaged, for a delay that changes nothing else about your plan.

3. Timing-linked money

Accrued leave payout, bonus payment dates, equity vesting dates and any severance entitlement are all attached to a date rather than to a decision. Moving a resignation by 6 weeks is frequently worth more than 6 months of additional saving, and it costs you nothing but patience.

Work out what is on the table before you choose the date. The severance pay calculator covers the entitlement side and the PTO accrual calculator covers the leave balance. If you are leaving because a redundancy is already in motion, the sequencing is different enough to deserve its own treatment, and the severance window is the one period where you hold both money and time at once.

Affordability is not the same question as "should I take a pay cut"

These two get collapsed constantly, and collapsing them is why capable people talk themselves out of moves they can comfortably make.

A move that pays 15% less, sits above your floor and rebuilds your savings is affordable. A move that pays 5% less and sits below your floor is not. The percentage change from your current salary compares you to your past. Your floor is a comparison to your life. Only one of them is load-bearing.

There is a related assumption worth checking, because it shapes how people read every number above. Roughly 7 in 10 respondents in our March 2026 career priorities survey said meaning and income both mattered equally to them, with only a small minority willing to trade either away, and the full breakdown sits in the Career Change Report 2026.

The reason this matters for a money article: if you are in that majority, then a plan that maximises income and ignores fit fails on its own terms, and so does a plan that chases fit and ignores the floor. The floor exists precisely so that fit becomes affordable. It is the constraint that lets you optimise for the other thing.

Your archetype changes where the floor sits

The formula is the same for everyone. What it evaluates to is not, because the two inputs you control, how fast you need to move and how much variance you can absorb, differ by which problem you are solving.

The quiz maps people on 5 struggle types crossed with 4 priority types, which resolves to 1 of 20 archetypes. The cell highlighted below is the one this article is mostly written for: someone leaving a career they can do, who still needs the income to work.

Practically, the cell you are in changes the answer in 3 ways:

• How long the runway needs to be. Someone changing field needs a longer one than someone changing employer within the same function, because the persuasion step lengthens every search.
• Whether the floor is negotiable at all. With dependants and a mortgage the floor is a hard constraint. Without them it is a preference, and preferences can be traded for speed.
• Which roles you should be pricing against. A switcher optimising for stability should be reading the 25th percentile column in the table above. One optimising for upside should be reading the 75th.

If you have not settled which of those you are, you are guessing at the two inputs that drive both numbers, which is the most expensive kind of guess available here.

What to do in the next 30 days

In order, because the order saves money.

1. Fix the dates first. Look up your retirement vesting schedule, your bonus payment date and your accrued leave policy. This step costs an hour and frequently pays for a month of runway.
2. Rebuild your burn rate as a post-quit number. Take out commuting and work-driven spending, add the full cost of health coverage, and use that figure as the denominator. Not your current outgoings.
3. Calculate both numbers. Runway from step 2. Floor salary from the formula above, with the repayment term included rather than set to zero.
4. Price the destination. Put your floor next to the wage bands for the roles you are targeting and see which column it falls in.
5. Then decide the sequence. If both numbers clear, the question is when. If the runway is tight but the floor clears, run the search from inside the role. If the floor does not clear, the fix is the burn rate or the target, and neither of those is fixed by waiting.

Steps 1 to 4 take an evening. The thing that most often stalls people is not the arithmetic; it is not knowing what to put in the "roles you are targeting" line, which is a direction problem wearing a money problem's clothes.

The bottom line

You can afford to quit when 2 things are true at once: your runway covers the tail of the search rather than its median, and the roles you are targeting pay above a floor that includes rebuilding what you spent. Almost every version of this question online answers the first and treats the second as somebody else's problem, which is why so many people who did the maths carefully still end up somewhere they cannot leave.

The costs that break the calculation are the ones an employer has been paying quietly: roughly $20,000 a year of family health premium, employer retirement contributions plus anything not yet vested, and money attached to dates rather than decisions. Correct for those 3 and the numbers you get will be pessimistic in the right direction.

The part the arithmetic cannot give you is the target. If the roles you are pricing against are still a guess, the free career quiz for adults is 26 branching questions and returns your archetype, career directions matched to it with fit scores, and the first concrete step for each, so the "roles you are targeting" line in the calculation stops being blank. Trusted by 9,800+ quiz takers.

If the question underneath yours is whether the timing has passed rather than whether the money works, is it too late to change careers takes that one directly. And once both numbers clear, how to change careers is the sequence for the move itself.
