Your break budget, not a generic monthly average

The first two numbers you enter are the ones that actually move the outcome: how many months you’re stepping away for, and what you expect to spend each of those months. At the defaults above — a 9-month break on $3,000 a month — that’s $27,000 of pure break cost before anything else gets added in. If you expect any income while you’re off — freelance work, a rental, consulting — enter it here too. The calculator subtracts it from your monthly spending automatically, so a $500-a-month side gig against $3,000 in expenses leaves a net burn of $2,500, not $3,000.

Your emergency fund is not your break fund

Savings and an emergency reserve go in as two separate numbers on purpose. The calculator subtracts your reserve from your total savings before it counts anything as available for the break — with $24,000 saved and a $6,000 reserve set aside, only $18,000 is ever treated as break money, no matter what else you enter.

Re-entry gets its own line, not a guess

Most people budget for the break and forget the weeks after it ends. Pick how many months of your post-break budget you want held back for job hunting, and that amount is carved out before the rest of your math runs — at the defaults, 2 months of a $3,000 budget reserves $6,000 that the break itself is never allowed to touch.

Debt doesn’t pause when you do

There’s no separate debt calculator here on purpose — a mortgage, car, or card payment is just another monthly cost during the break, and the field above reminds you to fold it in rather than track it twice.

The funding gap: one honest number

Everything above feeds a single figure: what you’d need in total (break spending plus re-entry buffer) minus what you actually have available. At the default numbers, that’s $33,000 needed against $18,000 available — a $15,000 gap, and the break map above it shows the same story visually: your money covers 4 of the 9 planned months before the re-entry buffer would be the next thing touched.

What if the break costs more than planned?

Right under the gap, the same calculation runs twice more automatically — once with spending 10% over what you entered, once at 20% over — and shows how many months stay funded in each case. No new fields to fill in, just the same numbers tested against a worse month.

The longest break you could actually afford

Separately from your planned length, the calculator works out the maximum break your current numbers support without ever touching your re-entry buffer. If that number is longer than what you planned, you have room to spare; if it’s shorter, that’s the same gap showing up from a different angle.

If income covers the break, the break itself no longer needs savings

Push your expected income during the break above your planned spending, and the calculator stops treating your savings as the limit entirely. The funding gap then only reflects your re-entry buffer, and the runway card reads “not limited by savings” instead of a shrinking number of months.

Change the plan and watch the gap move

Three sliders let you test the three real levers without re-entering anything: save more before you go, spend less per month once you’re there, or line up extra income while you’re off. Move any of them and the funding gap, the break map, and every card above recalculate immediately — there is no submit button because there is nothing to submit to.

Working backward from a start date

If you already know roughly when you want to leave, enter how many months from now that is. The calculator flips the calculation around and tells you the flat monthly amount you’d need to set aside between now and then to close whatever gap remains — and if that date has already passed, it says so plainly instead of showing a number that no longer means anything.
