Basic Financial Functions

The Financial Registers

In addition to the data storage registers discussed on page 27, the hp 12c platinum has five special registers in which numbers are stored for financial calculations. These registers are designated n, i, PV, PMT, and FV. The first five keys on the top row of the calculator are used to store a number from the display into the corresponding register, to calculate the corresponding financial value and store the result into the corresponding register, or to display the number stored in the corresponding register.*

Storing Numbers into the Financial Registers

To store a number into a financial register, key the number into the display, then press the corresponding key (n, ¼, $, P, or M).

Displaying Numbers in the Financial Registers

To display a number stored in a financial register, press : followed by the corresponding key.†

*Which operation is performed when one of these keys is pressed depends upon the last

preceding operation performed: If a number was just stored into a financial register (using n, ¼, $, P, M, gA, or gC), pressing one of these five keys calculates the corresponding value and stores it into the corresponding register; otherwise pressing one of these five keys merely stores the number from the display into the corresponding register.

†It’s good practice to press the corresponding key twice after :, since often you may want to calculate a financial value right after displaying another financial value. As indicated in the preceding footnote, if you wanted to display FV and then calculate PV, for example, you should press :MM$. If you didn’t press M the second time, pressing $ would store FV in the PV register rather than calculating PV, and to calculate PV you would have to press $again.
