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.

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.

Incorrect mortgage payments

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 need to know how to calculate mortgage payments

The formula is:
J
M = P x ------------------------

1 - ( 1 + J ) ^ -N
where:
M = monthly payment (\$)
P = principal (\$)
J = monthly interest (15% --> 0.15/12=0.0125 )
N = number months (years X 12) Note minus sign!

"^" represents the calculator's exponentiation function:
____ ____
This key: | y | not this key: | y |
| x | | e |
----- -----

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.

Simple loan payment

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!

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.
