Were you also clearing the financial memory with 2nd [CLR TVM], or just the storage memory? If you don't, it's going to keep using whatever value you last used for PMT.

BA II plus gives approximate answer for FV calculations


The 107,186.37 is what the future value would be if the interest per month is 0.58%, which is 6.96% per year. Try the following:
2nd [CLR TVM] 1 2 N 7 I/YR 1 0 0 0 0 0 PV CPT FV
As for rounding, you can change the calculator display to any number of digits (up to a limit, of course) by pressing 2nd [FORMAT] and then a number specifying the number of desired digits after the decimal point or 9 for floating decimal.

Will someone please walk me through the steps to calculate a mortgage payment on the BAII PLUS TEXAS INSTRUMENT. Please be specific. Thanks.


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.

Computing N in a TVM calculation (receive Error 5 message)


Hey,
Just found out the answer!
Apparently you can't have both FV and PV positive. Try the calculation with one of them being negative.

The BAII Plus comes from the factory set to assume monthly compounding. To fix this problem press 2nd then I/Y and enter 1 when prompted.
