About

Compound Interest projects how savings or an investment grows over time with compounding, including optional regular monthly contributions, and shows the year-by-year growth as both numbers and a chart, useful for seeing how much of the final balance is contributions versus interest earned. Nothing about your numbers is stored or sent anywhere; it's a client-side projection only.
