Figure 10 Cash flow diagram (Calculate FV)
The value in PMT should always be rounded to two decimal places when calculating FV or
PV to avoid small, accumulative discrepancies between non-rounded numbers and actual
(dollars and cents) payments. If the display is not set to two decimal places, press
\5G.

Example: A Savings Account
If you deposit 2,000 in a savings account that pays 7.2% annual interest compounded
annually, and make no other deposits to the account, how long will it take for the account to
grow to 3,000?
