How much savings do you need to quit your job?
Updated November 2026 · 6 min read
The honest answer is: it depends on your costs, not your salary. This guide shows how to turn your savings into a number of months, how big a cushion to keep, and what changes the answer.
Start with your runway
Your runway is how many months you could pay your bills with no income at all. The formula is simple:
Runway (months) = savings ÷ monthly expenses
If you have $18,000 saved and spend $2,500 a month, your runway is 7.2 months. Notice that your salary is not in the formula. Someone earning a lot but spending a lot can have a shorter runway than someone earning less who spends little.
Use the money you can actually reach
Count savings you could spend within days or weeks, such as a savings account or cash. Be careful with money that is locked up or costs you to withdraw, for example retirement accounts, where early withdrawal can mean taxes and penalties. A house is not a runway either.
Use your real monthly expenses
Look at the last three months of bank and card statements. Include rent or mortgage, food, transport, insurance, subscriptions and debt payments. People usually underestimate this number, so a little extra is safer than a little less.
Two costs often appear after you leave a job: health insurance (if your employer paid for it) and taxes (if you become self-employed and nobody withholds them). Add both to your monthly number before you calculate.
How many months is enough?
There is no single correct number. You will often see advice that says three to six months of expenses is a basic emergency fund. For a planned career change, many people want more, because you are choosing to give up income and the new income may take time to arrive. Whatever you choose, treat it as a floor you do not go below.
Here is a practical way to think about it:
- Under about 3 months of runway: build savings or reduce costs first, and try your idea on the side.
- About 3 to 6 months: possible, but only with a plan, and ideally some income lined up or a part-time way to start.
- More than 6 months: you have room to experiment, especially if your costs are low and your new path can earn within a few months.
These are rough rules of thumb, not guarantees. Your situation matters more than any chart.
What changes the answer
- How fast the new income arrives. A freelancer with clients waiting needs less runway than someone starting a business from nothing.
- Startup costs. Courses, equipment, licences and stock come out of your savings before your runway even starts.
- Other people. If a partner or children depend on your income, your safety floor should be higher.
- Debt. Fixed payments shorten your runway quickly.
- Your job market. If you could find a similar job quickly if things go wrong, your risk is lower.
Set a safety floor
Your safety floor is the number of months you promise yourself never to go below. If you decide on four months, then once your savings fall to four months of expenses, you stop and adjust: take on work, cut costs, or go back to a job. Only the savings above the floor are money you can spend on experiments.
Deciding the floor now, while you are calm, is much easier than deciding it when your balance is falling.
Do not make the jump in one step
The safest changes happen in stages: test the idea cheaply, get proof that someone will pay, move to part-time or lighter hours, and only then leave fully. Each stage should have a clear trigger, for example "I have three paying clients" or "my side income covers half my expenses for three months". That way you leave because the numbers say it is safe, not because you are tired of your job.
