Financial functions
The financial section of the calculator performs Time Value of Money (TVM) calculations for
compound interest that involve regular, uniform cash flows.
Using financial functions
A calculation must meet several prerequisites in order to use the financial functions successfully:
•
The amount of each payment must be the same.
•
Payments must occur at regular intervals.
•
The payment period must coincide with the interest compounding period.
•
There must be at least one positive and one negative cash flow.
A negative sign in the display represents money paid out; money received is positive.
To set a value for a variable, enter it and then tap the corresponding key. If a value is already
present, it is replaced with the new one.
Example: To set the number of payments to 50, tap 50
.
To review a previously set value, tap the
key once and then the value key.
To clear all set values, tap the
key twice.
Switch between calculating at the beginning or end of the period by tapping the
key.
Once five values are set you can tap a sixth to calculate it.
The number of payments or compounding periods.

amount. It occurs at the beginning of the first period.

occur at the beginning or end of each period.
