HP Financial Calculators » HP 10bII+ » Getting Started

This is a brief guide to using the HP 10-b II financial calculator.

Before you start, you need to setting up your HP 10-b II 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 explaination.

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:

  • Treat cash flows you are receiving as positive numbers.
  • Treat cash flows you are paying out as negative numbers.

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 10-b II 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 amortize, and the second # is the end of the interval you want to amortize. For example, to do the first five periods of a house loan, you’d press 1 {INPUT} 5 then press {AMORT}.

  • To display the amount of interest you paid this interval, press =.
  • To display the amount of principal you paid this interval, press = again.
  • To display the remaining balance of the loan, press = again.

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

If, at any interval beginning, you want to amortize 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), you’d press # {INPUT} # (in the example 6 {INPUT} 17 ). The first calculation would amortize 5 months of the loan (as shown above), and the second calculation would amortize the next 12 months of the loan. Then follow the steps above starting with {AMORT} to do subsequent 12 month intervals.

To calculate IRR and NPV

Enter the cash flows as follows, remembering the sign convention:

  • Clear previous data by pressing {C_ALL}.
  • To enter each flow, press # CFj, remembering Flow (0) is the flow at period zero; Flow (1) is the first flow, etc.
  • If a cash flow is repeated, enter the number of times it is repeated by pressing # {Nj}.
  • When you have entered the last cash flow
    • To calculate an NPV, enter the interest rate # {I/YR} followed by {NPV}.
    • To calculate an IRR, enter {IRR}.

    does the HP 10b11+ have the capabillity to calculate log0.9 and more logrithm functions?

      The 10bII+ does not have a key for the common logarithm function. You can use the natural logarithm function (LN key) to compute the common logarithm of a number using the relationship log(x) = ln(x)/ln(10). For example: 0.9 shift LN / 10 shift LN = -0.04576

    These instructions are terrible - they are for the 10bII and not the 10bII+ like the title page states. Totally different calculators. DO NOT BUY THE 10bII+
