The Product Market Fit (PMF) Calculator is a tool designed to help startups and businesses assess their product-market fit. It uses five key metrics to provide a comprehensive score:
By evaluating these factors, you can gain insights into how well your product meets market needs and identify areas for improvement.
Inspired by Auston Bunsen's PMF calculator, and countless AI tinkerers (this site was built using Claude, Cursor, and Github Copilot), I've built a quick little calculator to measure your product market fit, something that was not easy for most startup founders to quantify. Now it is.
For more of my work and experiments, check out my website Brian Breslin on the web or on twitter.
This is a free tool I'm providing to the startup community. If you found it helpful, please consider buying me a coffee.
