How Much to Save Before Quitting Your Job
The target is your essential monthly costs times the months you expect to be without income, plus the one-time cost of replacing employer benefits (price your own coverage; we make no claims about it), plus a re-entry buffer covering the weeks between your last old paycheck and your first new one. At $3,200 a month in essentials and six months of runway, that is $19,200 before the other two lines. Keep it in a separate envelope from your emergency fund.
Start with essential monthly costs, not your budget
The runway number is built on essentials, which is a smaller and more specific figure than what you currently spend. Housing, utilities, food, transport, insurance premiums, minimum debt payments, and anything that has a late fee. Not subscriptions, not travel, not dining out. Add those up for one month and you have the unit. If your essentials are $3,200, then every month of runway costs $3,200 and the arithmetic from there is simple multiplication. Doing it this way also gives you a second useful number: the gap between essentials and current spending is what you can cut during the search without changing anything structural, and knowing that in advance keeps the first lean month from feeling like a crisis.
Pick a month count you can defend
Most people pick three months because it sounds responsible and because they are imagining a best case. Pick a number you can defend instead. Ask people in your field who have recently changed jobs how long their search took from first application to signed offer, and use the longer end of what they tell you rather than the average. Factor in the seasonal dead zones in your industry, and the fact that senior roles usually take longer to fill than junior ones. Then multiply. At $3,200 in essentials, three months is $9,600 and six months is $19,200. The difference between those two numbers is the difference between quitting and having to take the first thing offered.
The two lines people leave out
First, benefits. When you leave, anything your employer was paying for stops, and replacing it is a real cost you have to price yourself. We do not advise on health coverage or any other benefit selection, so look up your own options and get actual quotes for your situation before you set the number. Second, the re-entry gap. Your last paycheck at the old job and your first at the new one are not adjacent; there is typically a start date, then a pay cycle, then a payday, and that gap can run several weeks past the day you signed. Add those weeks of essentials to the total. The offer letter does not pay rent.
This is not your emergency fund
An emergency fund exists for the things you did not choose: the car, the roof, the sudden layoff. A quit fund exists for something you are choosing on purpose, and it is designed to be spent down to nothing. If they live in the same account you will quit into what looks like a healthy balance and then meet an actual emergency in month three with the balance already half gone. Keep them separate and keep them separately sized. The rule is straightforward: you may quit when the quit fund is full and the emergency fund is untouched. If funding the quit fund requires draining the emergency fund, you are not ready yet.
How long it takes to build
Divide the total by whatever you can save monthly, and be honest that this is usually a long project. If your target is $19,200 plus benefits and re-entry, and you can save $800 a month, that is roughly two years. If you can save $1,600 a month, about one year. That timeline is itself information: it tells you whether you are planning an exit or hoping for one. The levers are the usual three. Cut, which raises the monthly contribution. Earn, through side income specifically routed to this envelope. Or reduce the target by lowering essential costs, which does double duty because it shrinks both the monthly unit and the number of dollars each month of runway requires.
The envelope change to make today
Open a Quit Fund envelope and set its target as a month count times your essential monthly costs, so the balance reads as months of freedom rather than as an abstract dollar figure. That framing is what keeps it from being raided, because spending $600 out of it is visibly spending a fifth of a month. Beside it, keep an Emergency envelope that you do not touch for this purpose at all. In Envelope Budget both can sit on the same screen with separate targets, and the widget puts the runway number where you will see it on the days the job is worst, which is exactly when the plan needs to be visible.
Common questions
Is three months of expenses enough to quit on?
It depends entirely on how long hiring takes in your field, and three months is optimistic for most professional roles once you account for interview cycles, notice periods, and the gap before the first paycheck. Ask people who have recently made the same move in your industry and use the slow end of their answers. If three months is all you can build, know that you are accepting a real risk of having to take the first offer that arrives, which is often how people end up in a job worse than the one they left.
Should I quit before I have another job lined up?
That is a personal and situational call, and the budgeting contribution is narrow: the fewer months of runway you have, the more the decision gets made for you by the balance rather than by you. If you have a full quit fund plus an untouched emergency fund, leaving without a next role is a funded choice. If you have six weeks of essentials, it is a countdown. Build the number first and the decision gets easier, because you will be choosing between options instead of reacting to a deadline.
What if I need to leave sooner than the fund allows?
Then shrink the target rather than pretending the number is met. Reduce essential monthly costs, which lowers the cost of every month of runway. Line up part-time or contract income that covers part of essentials so each dollar of the envelope stretches further. Or reduce the month count deliberately, with your eyes open about what that means for your negotiating position. Any of those is more honest than leaving on a partial fund and calling it a plan, because the shortfall does not disappear, it just shows up in month four.
