About Creator Tool Lab
Creator Tool Lab provides free browser-based calculators and text utilities for creators, freelancers and small business teams. Our aim is to make routine calculations understandable: clear inputs, readable results and explanations of what each result means.
How the tools work
Calculations run on your device using JavaScript. There is no account requirement, and tool inputs are not sent to our servers by the application. Monetary outputs currently display USD; the formulas also work for GBP, CAD or AUD when every input uses the same currency. No currency conversion or tax calculation is performed.
Our content approach
Our guides explain each formula, show a worked example and describe practical limitations. We correct errors when identified. Last updated: October 9, 2026.
Funding
The tools are free. Display advertising may fund the service in the future. Advertising is currently inactive. Estimates in the ad revenue calculator are scenarios, not income promises.
