About these tools

Every tool on this page is free, works on mobile, and runs entirely in your browser — nothing you type is sent to a server or stored. The pricing and fee figures behind the tutoring calculators come from the same research we use across the directory of 100+ tutoring platforms, so the results reflect what platforms actually charge and pay. Results are estimates to guide your decision, not quotes; always confirm current rates and fees on the platform itself.
