HP 10bii Getting Started

This is a brief guide to using the HP 10bII financial calculator.

Before you start, you need to setting up your HP 10bII calculator. To set the number of digits after the decimal point.

To enter the number of periods in a year, press # and press the (yellow-orange) ‘gold shift’ and press {P/YR} (for example, enter 12 {P/YR} for monthly). Click here for more explanation.

To set cash flows to the beginning of period or the end of period, press and press {BEG/END} . This toggles between ‘begin’ mode and ’end’ mode.

You should use the following convention when you work on financial calculations:

To turn a positive number into a negative number, enter the number on your keypad and press {+/-} key.

In each of the above calculations, remember the sign convention! If you have an error, either that or omitted data is the most likely cause.

Using HP 10bII To amortize a loan

Do the steps for annuity payment as shown above. Then enter # {INPUT} # where the first # is the beginning of the interval you want to amortise, and the second # is the end of the interval you want to amortise. For example, to do the first five periods of a house loan: Press 1 {INPUT} 5 then press {AMORT}.

To do the next interval of equal length, simply press {AMORT}.

If, at any interval beginning, you want to amortise a different length next interval (for example, if you had 12 months of payments on your house loan after a short first interval of 5 payments), press # {INPUT} # (in the example 6 {INPUT} 17 ). The first calculation would amortise 5 months of the loan (as shown above), and the second calculation would amortise the next 12 months of the loan. Then follow the steps above starting with { AMORT} to do subsequent 12 month intervals.
