About this calculator

Continuous compounding is the theoretical limit of compound interest as the number of compounding periods per year approaches infinity — instead of compounding monthly, daily, or even hourly, interest is compounded at every instant. It is calculated with the formula A = Pe^(rt), where P is the principal, r is the annual interest rate, t is time in years, and e is Euler's number (approximately 2.71828).

While few real bank accounts actually compound continuously, the formula is foundational in academic finance and derivatives pricing — it underlies the Black-Scholes option pricing model and is used as a clean mathematical benchmark for the maximum possible growth from a given rate. This calculator takes your principal, annual rate, and time in years and returns the future value under continuous compounding.
