How Much Runway Do You Need Between Jobs? (Free Calculator)
Your runway is the most useful number to know before you quit, pivot, or take a lower-paying job you actually want. Here’s how to calculate it — and a free tool that does it for you.
“Runway” is the number of months you can cover your essential expenses without a paycheck. It’s the single most useful number to know before you quit, take a career break, or accept a lower-paying job you actually want — and most people have never sat down to calculate it.
This guide shows you how to work out your runway, how many months to aim for, and how to make savings last longer. Start with the calculator, then read on for the reasoning.

How long your savings last — and how fast a job offer rebuilds them.
Estimates only — not financial advice. Take-home uses a flat effective rate, not a real tax calculation; your actual figures depend on filing status, state, deductions, and benefits.
How to calculate your runway
The formula is simple:
Runway (months) = Liquid savings ÷ (Monthly essential expenses − Income during the gap)
Liquid savings means cash you can actually spend — checking, savings, and a money-market or brokerage cash balance. Don’t count retirement accounts you’d pay penalties to touch, or home equity you can’t quickly access.
Essential expenses are the bills that don’t stop when your income does: rent or mortgage, utilities, groceries, insurance, minimum debt payments, and transportation. This is your lean budget, not your normal one — dining out and subscriptions can pause.
Income during the gap is anything still coming in: severance, a partner’s contribution to shared costs, freelance or side income, or unemployment benefits if you qualify. Subtract it from expenses to get your true monthly burn.
How many months of runway should you have?
There’s no universal answer, but these are the common reference points people use when deciding whether they can afford to leave a job:
- 3 months — a floor. Reasonable if you’re in a high-demand field, have a strong network, or a specific offer already in hand.
- 6 months — the figure most often cited for a voluntary job change. Enough to run a real search without taking the first thing that comes along.
- 9–12 months — for a career pivot, a move into a slower-hiring field, or if you’re the sole earner. Longer searches are normal after 2023–2025’s cooler market.
These are starting points, not rules — your right number depends on your field, your dependents, and how quickly you realistically expect to land. The point of calculating it is to replace a vague “I think I have enough” with a number you can plan around.
How to extend your runway
Runway is a fraction, so you can lengthen it two ways — a bigger top or a smaller bottom:
- Cut the burn, not the life. Pausing subscriptions, renegotiating insurance, and moving to a lean grocery budget can shave hundreds off monthly burn without much pain. Every $200/mo you cut adds real months.
- Add gap income. Even modest freelance or part-time income lowers your net burn dramatically — because it comes straight off the bottom of the fraction.
- Build the cushion before you leave. If you can, bank a few extra months while you’re still employed. The best time to extend your runway is before you need it.
Can I afford to quit? A quick checklist
- I know my lean monthly burn (not my normal spending).
- My runway covers a realistic search length for my field.
- I’ve accounted for health insurance (COBRA or a marketplace plan).
- I have a small buffer on top for the unexpected.
- I’ve modeled what a lower — or higher — offer does to my finances.
If you can check most of these, you’re making an informed decision rather than a hopeful one.
“What if I take this $X job?”
The offer on the table isn’t just a salary — it’s a take-home number, a monthly surplus, and a rebuild timeline. A lower-paying job you love can still be the right move if it covers your essentials and slowly rebuilds your cushion; a higher one that comes with a punishing commute or cost-of-living jump might not stretch as far as it looks. The calculator above estimates the take-home and how quickly each offer rebuilds your runway so you can compare them honestly.
Frequently asked questions
How many months of expenses should I have before quitting?
Most people aim for around six months of essential expenses for a voluntary move, less if they have an offer in hand and more (9–12 months) for a career pivot or slower-hiring field. Base it on your lean budget and a realistic search length, not a round number.
What counts as “runway”?
Cash you can actually spend without penalty — checking, savings, and accessible brokerage cash. It excludes retirement accounts you’d be penalized to withdraw from and illiquid assets like home equity.
Does severance or unemployment count?
Yes — count it as “income during the gap.” It lowers your net monthly burn, which stretches your runway further than an equivalent amount of one-time savings would.
How do I estimate take-home pay from an offer?
A quick estimate is salary × (1 − your effective tax rate), divided by 12. The calculator uses a combined federal + FICA + state rate you can adjust. For an exact figure, use your state’s withholding tables or a dedicated paycheck calculator.
