A formula for calculating compound interest For example, suppose that the principal is 10000 and the monthly income is 10%. Add up the monthly income. That is to say, the principal in the second month is 11000. What is the total income after one year? What is the formula?

Suppose P is the principal, f is the total income, I% is the monthly income, and N is the number of months
F = P * [(1 + I%) to the nth power]
