About SideGig Math

SideGig Math is a small collection of free calculators for people who earn money on their own terms: freelancers, online sellers, creators and anyone running a side hustle.

Pricing your work, understanding fees and setting realistic income goals usually means wrestling with spreadsheets. Each tool here answers one question quickly, shows the formula it uses, and walks through a worked example so you can check the math yourself.

How the tools work

Every calculator runs entirely in your browser. The numbers you type are never sent to a server or stored by us.

A note on accuracy

We check formulas carefully and update fee-based tools when platforms change their pricing. Still, results are estimates for planning purposes and are not financial, legal or tax advice. For decisions with real consequences, confirm with the platform's official pages or a qualified professional.
