When Can I Quit? Calculator

It's 11pm on a Tuesday. You just finished a client project after your day job. The Stripe notification felt good. You open your spreadsheet—the one with your "quit fund" math—and wonder: Am I actually getting closer?

You've been running this loop for months. Maybe years. Side income growing. Expenses roughly known. But you still don't have the number—the specific dollar amount in savings that would let you quit without panic.

Most solopreneurs-in-waiting solve this with mental math. "If I save $X per month, and my expenses are $Y, then maybe in Z months..." A good month makes you feel ready. A slow month makes you feel years away. The answer keeps moving because you're not tracking it—you're guessing at it.

Some have a spreadsheet. Most don't trust it. The ones who do still don't have a clear answer to "when"—they have a vague sense of "probably next year if things go well."

This template turns "probably next year" into a date.

• Track your real monthly expenses—not the optimistic version. Log your side income over time so you can see the trend, not just this month. Model scenarios: What if income grows 10%? What if you cut expenses by $500? What if you need 12 months of runway instead of 6?

• The output is your quit number and the date you'll hit it. A specific Thursday in October, not "sometime next year."

The cost of getting this wrong is real. Quit too early and you're panicking in month 4 when a client churns. Quit too late and you spend two extra years at a job you've mentally left, building resentment instead of building your business.

The sample scenario shows a freelancer making $3,200/month on the side with $4,800 in monthly expenses. See when the math says go, then plug in your numbers.

Know your number, not your guess.
