I am using Texas BAII Plus. The problem is when I try to calculate the NPV, N, PV,PMT, FY. it does not provide the right figure. It was ok until this morning. I think I might press something wrong. However, after the reset, it still not working properly. Please help

The calculator has different worksheets.
To access TVM worksheet, press [2nd] and any TVM key : N, I/Y, PV, PMT or FV
To enter Amortization worksheet, press [2nd][AMORT]
To access Cash Flow (problem with unequal cash flows) Press CF, or NPV, or CPT or IRR
To access BOND worksheets press [2nd][BND]
For depreciation worksheets press [2nd][DPR]
For statistics, use [2nd][DATA], or [2nd][STAT].
There are other worksheets [2nd][Delta%], [2nd][DATE], [2nd][PROFIT], [2nd][BRKEVN],[2nd][MEMory].

These shortcuts will not get you anywhere if you do not consult the manual.

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.

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.

Click APPS and then ENTER for Finance and then ENTER again for the TVM Solver. There you can input the PV, PMT, i, etc.

Check to make sure you have the proper value set for payments-per-year.

PV=1,077,202 while FV=1,000,000 ? I wonder somebody will lent me $1,077,202 and accept to get back $1,000,000 in 10 years later.
Your example's got prob, guy !

You need to have your PV and your PMT be a different sign. Try making your payments negative.

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
