I just got my BA II Plus and I am trying to use it to calculate out interest only payments. Principal amount is $1,160,000.00 monthly payments has to be around $5,000 per mo. then a balloon payment paid in (12 years) 144 mo. what would be the formula to find the monthly and at what interest rate?

I gave up using the Texas BA II. I used an on-line mortgage calculator for interest only. I was able to get a full printout.

I would like to learn more about the BA II and how to do this type of math on it.

Thank you

$596.57 is what I get with payments occurring at the beginning of the month. Set it to handle payments at the end of the month. My calculator gives $599.55 for this case.

I'm not sure about the BA RE, but on the BA-II Plus you change the Begin/End setting by pressing 2nd [BGN] and 2nd [SET].

Work with the simple formula:
Interest = Initial * rate * time

To find the total amount, add the Initial plus the Interest, then subtract what has been paid. This will change the amount of money that will be accruing interest, though, so if there is a payment schedule you will need to repeat this calculation to get an exact number.

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.

That depends on the interest rate.

2nd [CLR TVM] (clear previous data)

5 0 0 0 PMT (monthly payment)

2 0 2nd [*P/Y] N (20 years of monthly payments)

annual interest rate I/Y (annual interest rate)

CPT PV (compute present value)

At 10% it's about $518,000

2nd [CLR TVM] (clear previous data)

5 0 0 0 PMT (monthly payment)

2 0 2nd [*P/Y] N (20 years of monthly payments)

annual interest rate I/Y (annual interest rate)

CPT PV (compute present value)

At 10% it's about $518,000

2nd [CLR TVM] (clears any previous results)

4 I/Y (4% interest rate)

1 2 0 0 +/- ($1200 monthly payment, negative because you're paying out the amount)

2 5 0 0 0 FV (desired value, positive because you'll be receiving the amount)

CPT N (compute the number of payments)

4 I/Y (4% interest rate)

1 2 0 0 +/- ($1200 monthly payment, negative because you're paying out the amount)

2 5 0 0 0 FV (desired value, positive because you'll be receiving the amount)

CPT N (compute the number of payments)

100000+8%= Divide by 360

set your p/y to 12( compounding periods per year). I think you are calculating for a one year loan?

Nov 18, 2008 | Texas Instruments BA-II Plus Calculator

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!

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.
