What is this tool?
Compound interest applies gains not only to your starting principal but also to accumulated interest from earlier periods — the hallmark of long horizon investing narratives. Our calculator visualizes the standard textbook formula A = P (1 + r/n)^(nt) where P is principal, r annual nominal rate, n compounding periods per year, and t years. Actual banking products layer fees, taxes, floating coupons, and principal additions; treat outputs as directional pedagogy.
