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?
Note:
Because C/Y (compounding periods per year) is automatically set
to equal P/Y (payments per year), you must change the C/Y value.
Answer: You must make monthly deposits of $203.13.
