Hi,

My hp 12c calculates a mortgage payment about $100 more than it should be. Is this fixable or is it history?

Thanks,

Mel

Check to see if the word "BEGIN" appears on your screen. If so, you are calculating the payment on an "annuity due" basis, that is, the first payment is made on day one, and each period thereafter, rather than the first payment being due at the end of the first (30 days usually) period. To fix this, press the blue "g" button, and then press the number "8" (notice the word "end" printed on that key in blue ink). This should return you to the normal (first payment due at the end of the period) option.

HP actually provides the specific keystrokes for Canadian mortgage calculations on the HP-12C calculator in their "*Hewlett-Packard HP-12C Solutions Handbook*". The link to this PDF document is provided below. See pages 136 through 138.

There is an excellent computer-based tutorial for the HP 12c Platinum on HP's website (although the sequence for TVM calculations is the same for the original 12c).

Download it and have a look. It will guide you key-by-key through the steps.

The C indicates the calculator is using compound interest for the odd period. To use simple interest, press STO EEX

As for the wrong payment value, could you post an example? It's hard to tell which setting you may have wrong without some numbers.

if interest rate is 5%,
enter 5 divided by 12 = %i
if 30 year mortgage,
enter 360 N
enter 2nd PMT to get monthly principle and interest.

Check to see if you are specifying the payment to be at the beginning or end of the month. This may help.

My problem is that my HP12c calculates the mortgage payment almost twice as much as it should be.....
