Education only
Lessons and labs explain how money works. They are not advice on what to do with yours.
Official sources
Tax figures come from the IRS, and each chapter links the IRS, CFPB, FDIC and Investor.gov pages it relies on.
Assumptions on screen
Each lab lists what it assumes and where it simplifies, so you can see what the number leaves out.
Your numbers stay with you
Progress lives in this browser until you sign in to sync it. The AI coach is the one exception: your questions to it go to our AI providers.
