The Quit My Job Runway Calculator

The Runway Number

Before going freelance, launching a business, or taking a career break, understanding your runway helps: the number of months your savings will support your lifestyle without income. This calculator gives you that number clearly, with adjustments for part-time income and variable expenses.

What Runway Is Enough?

Financial advisors typically recommend 6–12 months of runway before quitting. Entrepreneurs often require 18–24 months to reach consistent income. Your target depends on your risk tolerance, alternative income streams, and how quickly your new income model can scale.

The Expenses People Forget to Count

Many people find that their monthly costs shift significantly once they leave employment. Things like private health cover, professional subscriptions, and self-employed tax contributions can add up quietly in the background. It can help to audit your current spending carefully before running the numbers. Are you accounting for irregular expenses — annual renewals, quarterly bills, or seasonal costs? Spreading those across twelve months and folding them into your monthly figure tends to give a much clearer picture of what your runway actually looks like in practice.

Why Keeping a Reserve Matters

One approach many people take is ring-fencing a portion of savings that simply does not get touched. This is worth noting not just for genuine emergencies, but for the psychological comfort it provides during uncertain early months. Knowing a buffer exists can make decision-making calmer and less reactive. The calculator allows you to set that reserve separately, so your runway figure reflects only the money you are genuinely comfortable spending down.

Run it with sensible defaults

Using total accessible savings of 30,000, monthly living expenses of 2,500, expected monthly side income of 500, emergency reserve to keep untouched of 5,000, the calculation works out to 12.5 months. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Total Accessible Savings, Monthly Living Expenses, Expected Monthly Side Income, and Emergency Reserve to Keep Untouched — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
