r = annual rate of interest;
t = time in years.

Suppose the amount invested (or borrowed) is K, Suppose the rate of interest is R% annually, Suppose the amount accrues interest for Y years. Then the interest I is 100*K[(1 + R/100)^Y - 1]
A=Pe^rt A=Total Invested P=Principal r=Rate t=time
If the rate of annual interest is r% the period is n years and the amount invested is y Then the compound interest is y*(1+r/100)^n - y
The "principal" is the sum of money invested or borrowed, before interest or other revenue is added, or the remainder of that sum after payments have been made. In math, this applies to finance.
