Question about HP 12c Calculator

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.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

SOURCE: incorrect claculation

I get an answer of 366.91 in my 12C as well. You might try either putting in a zero for FV before hitting the [PMT] key, or clearing your registers before doing the problem, as you may be picking up an old value from a previous problem in the FV register.

SOURCE: wrong calculation of mortgage payment

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.

This is happening because your calculator is converting the 10% interest figure into a monthly amount (ie 0.833333%), but it isn't changing the number of periods or the periodic payment into monthly equivalents. In both cases, it is assuming that payments are made at the end of each period.

So the figure of 10,168.06 is arrived at as follows:

end of period 1: 2,000.00

end of period 2: 2,000 x 1.00833333 + 2,000 = 4,016.67

end of period 3: 4,016.67 x 1.00833333 + 2,000 = 6,050.14

end of period 4: 6,050.14 x 1.00833333 + 2,000 = 8,100.56

end of period 5: 8,100.56 x 1.00833333 + 2,000 = 10,168.06

whereas the figure of 12,210.20 is arrived at as follows:

end of period 1: 2,000.00

end of period 2: 2,000 x 1.1 + 2,000 = 4,200.00

end of period 3: 4,200 x 1.1 + 2,000 = 6,620.00

end of period 4: 6,620 x 1.1 + 2,000 = 9,282.00

end of period 5: 9,282 x 1.1 + 2,000 = 12,210.20

You will need to find out from your user manual how to stop this from happening, so that all the numbers remain as annual figures. It will involve setting the number of payments per year [P/YR] to 1 instead of 12.

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.

The CPT button is a feature of TI calculators. HP calculators don't need it. To compute a result, simply press the appropriate button without making any data entry.

For example, to compute PMT after entering n, i, PV, and FMT, simply press the PMT button, instead of pressing CPT then PMT as with a TI calculator.

You don't need one. Some other calculators require you to press the CPT button and then the button specifying what you want the calculator to compute (PV, PMT, etc). The HP knows whether you've just entered a number or not. If you haven't entered a number, simply pressing the key will compute the value. So for example, if the book says press CPT and then press PMT to calculate the payment, you just need to press PMT.

For a thirty-year, $100,000 mortgage at 8% annually, compute the monthly payment:

2nd [CLR TVM] ( clear the time value of money registers )

3 0 * 1 2 N ( thirty years at twelve payments per year )

8 I/Y ( 8% annual interest )

1 0 0 0 0 0 PV ( $100,000 mortgage )

CPT PMT ( compute payment )

You should see -733.76. The negative indicates payment, the amount is $733.76.

2nd [CLR TVM] ( clear the time value of money registers )

3 0 * 1 2 N ( thirty years at twelve payments per year )

8 I/Y ( 8% annual interest )

1 0 0 0 0 0 PV ( $100,000 mortgage )

CPT PMT ( compute payment )

You should see -733.76. The negative indicates payment, the amount is $733.76.

Enter the number of months, press N. Enter the annual interest rate, press I/Y. Enter the amount of the loan, press PV. Press CPT then PMT to calculate the amount of the monthly payment.

Full details, as well as how to do other types of calculations, are in the manual.

If $100,000.00 loan: enter 100000. in pv,
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.
You may have already solved this problem.

Aug 19, 2010 | Texas Instruments BA Real Estate...

what numbers are you putting in? For example, I just plugged in

N=360 (12m/30y)

I/Y = .5833 (7/12m)

PV = 200000

FV = 0 (it will be paid off)

PMT = 1,330.6050

The only thing I could offer is that perhaps you forgot to enter one of the variables...?

Here is the link to a guide;

http://www.buec.udel.edu/bowersh/finc311_F04/Documents_f04/Quick%20Guide.pdf

Set PV=-$100,000

[2nd] P/Y= 12.00

N= 12 x 30 = 360, (i assume it's 30 Y amortization)

I/Y = 5.75%

FV = 0

[CPT] PMT

Hope this helps

Clear calc and mode registers & select two decimal places- ON/C, 2nd, CMR,FIX,2

Select FIN Mode - 2nd, FIN repeat until FIN shows up in display

Enter months in mortgage - N

Divide annual interest rate by 12 - Enter result as %i

Subtract down payment from cost of home - Enter result as PV

Compute monthly payment - 2nd, PMT

for Payments at beginning of month , press DUE, PMT

I have a question for you, what battery does the TI BA-II Constant Memory calculaor use?

Much thanks.
