**Financial Keys**-
N, number of periods

%i, rate of interest per period

PMT, payment per period

PV, present value

FV, future value **Conventions**-
Payments are always positive numbers.

Future values are balances, usually entered as positive numbers.

At least one of PMT, PV, and FV must be zero. **Floating Decimal**- Press FIX 9.
**Financial Mode**- Press 2nd MODE until FIN appears in the display.
**Clearing Financial Data**- Press 2nd CMR.
**Beginning Annuities**- Substitute the DUE key for the 2nd key at the time you compute the missing value.
**Entering Financial Data**- Display the value, then press the financial key.
**Computing Values**-
Press 2nd, followed by the financial key to be computed.
**Example:**- Tom's account begins with $500,
and earns 6% per year, compounded monthly. He deposits an additional
$50 at the end of each month. What will the balance be at the end of
one year?
The variables are:

N = 12 I = 6/12 PMT = 50 increasing PV = 500 FV = ??? - The keystrokes are:
- 2nd CMR

12 N

0.5 %i

0 PMT

500 PV

2nd FV

- Then we enter the following:
- 2nd CMR

12 N

0.5 %i

50 PMT

0 PV

2nd FV

The second intermediate answer is $616.78. This is added to the first intermediate answer to produce the final answer, $1,147.62, rounded to the nearest cent.
