The badge shows how much that amount could grow at compound interest over a chosen time horizon (default: 40 years at 9% per year). Purpose: Education and awareness only. The extension helps you see the potential future value of money spent today (e.g. $100 at 9% for 40 years ≈ $3,140). It is not investment advice and does not guarantee future returns. All values are illustrative and depend on your chosen rate and time horizon.
