About CalcHub

CalcHub is a collection of free calculators for people who earn money online — sellers, creators, freelancers and small business owners. Every tool answers one question honestly: what do you actually keep?

How the numbers are made

Each calculator is built on the provider's published fee schedule or widely reported market data, with the assumptions listed directly on the page and links to official sources where they exist. Rates change — every page shows a "last reviewed" date, and we recommend verifying figures against the provider's current documentation before making financial decisions.
