The Ultimate Bootstrapping Calculator

Leaving a job to build something is a scary decision to make.

This tool is here to help you having all the necessary information before making it.

(savings, opportunity cost, runway, time to 1st $, growth,...)

Who made this?

I'm Pierre de Wulf, 2 years ago I left my job and tried to build profitable businesses instead.


Me and my co-founder failed two-times before finally building something that seemed to have a bit a of success.


I've made this to quickly visualize what you give up when you leave your job and what does it really take to bring money home.


The source code can be found here, do not hesitate to contribute if you'd like to.


I also have my own blog where I regularly talk about bootstrapping, data-analysis and web scraping.
