My ba II plus won't calculate mortgage pmt - Texas Instruments BA-II Plus Calculator

Make sure you have P/Y set to 1 and BGN/END set to END. With those settings, pressing 9 I/Y 9 2 0 FV 1 0 0 +/- PMT CPT N should produce 7.00 .

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.

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.

You have the number of payments per year set to one, so the calculator is telling you that you will get annual payments of 7500 on your investment. To set the number of payments per year to twelve, press 2nd [P/Y] 1 2 ENTER 2nd [QUIT]. Now pressing CPT [PMT] should give you the monthly payment of 805.28.

clear your memory by hitting <2nd> then <FV>. It will clear out the memory of any values that may be stuck which will return incorrect answers

I get 6.085%. Make sure the fv and pmt are of opposite signs. You're either making annual payments and getting a lump sum back at the end, or receiving annual payments and then paying it all back in a lump at the end. Either way, the money is moving in opposite directions.

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...?

Are you putting 30x12=360 for N? Since you have monthly payments, you have to compute it a little different. Also, you have to find the effective monthly interest rate. 1.0575^(1/12) = .4669839%.

Another way is to enter 30 for N and 5.57 for I/Y, and change P/Y to 12.

Hope this helps!

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.
