About us
Built for people who just want the answer
Niche Calculators is a free collection of practical calculators for marketers, freelancers, founders, and small business owners — people who need numbers fast and don’t want to build a spreadsheet to get them.
Why we built this
Every marketer has Googled “how do I calculate ROAS” and landed on a wall of text with the formula buried in paragraph six. Every freelancer has opened Excel just to figure out what to charge for a project. Every founder has tried to reverse-engineer a break-even point on the back of a napkin.
We built Niche Calculators because the calculation itself shouldn’t be the hard part. Input your numbers, get your answer, move on.

How it works
Every calculator on this site comes with a short explainer covering what the metric actually means, the formula behind it, a worked example, and benchmarks to help you interpret your result. The goal isn’t just to compute a number — it’s to help you understand what it’s telling you.
No sign-up. No account. No paywalls. Just the calculator.
