Can I afford to quit my job for my startup?
You can afford to go full-time when your project either already covers your living costs, or your savings buy you enough months to get it there before the money runs out. The two numbers that decide it: how many months your cash lasts (your runway), and whether the business covers its own costs (break-even).
It comes down to two questions
First: if you stop drawing a salary, how many months can you live on your savings plus whatever the project earns? Second: is the project on track to pay for itself (and you) before that runs out? If yes to both, you have a real runway to make the jump. If not, you know exactly how much more revenue or savings you need first.
Quitting is a money decision dressed up as a courage decision. The courage part is easier once the money part is a number, not a feeling.
The words: runway, break-even, default alive
The months your money lasts = your runway. The point where the business covers its costs = break-even. If you hit break-even before your runway ends, you are "default alive" — you survive without needing more money. That is the green light most founders are actually looking for.
A common rule of thumb: have enough savings for 12-18 months and a project already showing real, growing revenue before you leave a stable income.

FAQ
How much revenue should my side project make before I quit?
Enough that, combined with your savings runway, the project reaches break-even before the money runs out. There is no universal number — it depends on your living costs and savings. The honest answer is your own projection, not a generic figure.
How many months of savings should I have before going full-time?
A common guideline is 12-18 months of living costs, ideally with a project already earning and growing. The more your project covers, the less savings runway you need.
