What is Exponential Growth Formula?
The exponential growth formula describes a mathematical process where a quantity increases by a fixed percentage over regular time intervals. In continuous compounding, the exponential growth formula is written as Final Value = P × e^(r × t), where P is the initial value, r is the growth rate as a decimal, t is the time period, and e is Euler's number. This exponential growth formula applies to compound interest, population dynamics, bacterial growth, and radioactive decay. Understanding the exponential growth formula helps you project how an investment grows when interest compounds continuously. The same exponential growth formula also works for decay when the growth rate is negative, making it a versatile tool for many scientific and financial calculations.
