Freelance Runway Calculator

How to use this calculator

Enter the savings you could genuinely spend if work dried up. That means accessible cash — not money already earmarked for a tax bill, not a deposit you've promised to something else, not funds locked in an account you'd be penalised for touching. Being strict here is the whole point; a runway number you can't actually draw on isn't runway.

Then enter your average monthly expenses. Include rent or mortgage, utilities, food, transport, insurance, debt repayments, subscriptions, and the business costs that keep running whether or not you have clients — software licences, phone, professional insurance. Use an average of the last three months rather than an idealised budget. If your spending varies a lot, use the higher end.

What the output means

The headline is how many months you could cover with zero income starting today. It's a worst-case figure by design: in reality income rarely goes to exactly zero, and most people cut discretionary spending fast when it drops. Treat it as the floor of your situation, not the forecast.

The six-month reserve target and the gap beneath it give you something to aim at. Six months is a common benchmark for irregular income because it covers a typical bad quarter plus the lag between winning new work and actually being paid for it — a lag that catches people out, since a client signed in March might not pay until May. If your work is highly seasonal, or you have dependants, or your niche has long sales cycles, aim higher.

What runway actually buys you

The value of a long runway isn't survival, it's leverage. With one month of cover, you take the next thing offered at whatever it pays, because you have to. With six, you can decline underpriced work, hold your rate through a negotiation, walk away from a client who pays late every single time, and spend two unpaid weeks pitching better work instead of filling the calendar with worse work. Almost every pricing mistake freelancers make is downstream of a short runway.

If the number is uncomfortable, there are only three ways to move it: spend less each month, save more from the work you already have, or raise your rate. The first shows up immediately in this calculator — try lowering your monthly expenses by a few hundred and watch how many extra weeks it buys, because reducing burn improves runway faster than saving does. The third is where the other tools on this site come in.

Recalculate quarterly, and always before a big decision: leaving a job, hiring, taking on a lease, or turning down a large but badly-paid contract. It takes thirty seconds and it's the single most sobering number in a freelance business.
