INITIAL CAPITAL FOR A REGULAR

This program determines the initial capital required to allow regular withdrawals for a period of time. The initial capital depends on the amount and frequency of withdrawals, the duration in years and the interest rate paid on the capital. The program calculates based on the data entered, the amount of capital corresponding to a zero balance after the last withdrawal. Any capital greater than that calculated will leave a positive balance under the same conditions.

Example

How much do we need to invest at 6% to be able to withdraw $ 100 monthly for 5 years?
