The formula for exponential growth is V = S x (1+R) T, where S is the starting value, R is the interest rate, T is the number of periods that have elapsed, and V is the current value.

Type "=A1/ (1+B1exp (C1D1))" without quotes into an Excel cell. Type the value of the function's "N" constant into cell A1. For example, if you want to chart the growth function, type "1,800 ÷ (1 ...

With exponential growth, the number of new cases each day constantly increases —graph the total over time, and you’ll see that the line curves upward—and that can get you into big numbers ...
