Compound Interest Calculator
Estimate nominal and inflation-adjusted future values with decoupled compounding and contribution structures.
The power of compounding
Compound interest accelerates capital growth by earning returns on previously accrued interest in addition to the principal base. The basic compound formula is: A = P(1 + r/n)^{nt}.
By decoupling compounding frequency from recurring contribution frequency, this tool calculates precise transient changes. Continuous compounding uses $A = P \cdot e^{rt}$ as an upper boundary limit, and the inflation rate allows projecting real future purchasing power.
