Example: Computing Regular Deposits for a
Specified Future Amount

You plan to open a savings account and deposit the same amount of
money at the beginning of each month. In 10 years, you want to have
$25,000 in the account.

How much should you deposit if the annual interest rate is 0.5% with
quarterly compounding?

to equal

P/Y

(payments per year), you must change the
