Question about Texas Instruments BA-II Plus Calculator

# Simple loan payment

The most common calculation would seem to be home loan payments. For the life of me, I can't get the correct answer with this blassed thing. I have a 200,000 mortgage for 30 years at 5.75% with monthly payments. How do I calculate it with this TI BA II Plus? Thanks.

In calculating a 100,000 mortgage at 7 % interest for 20 years I get a payment of 967.26 per month. pv=100,000, I/Y= 7, N=240 However it should be 775.30. What am I doing wrong

Input the followinw:

-200,000 PV
5.75 I/Y
30 N

CPT PMT

Note: If the interest is compounded monthly then you have to multiply 30 by 12 and divide 5.57 by 12.

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!

200,000 (PV) 5.75 (I/Y) 30 (2nd) (N)(N) (CPT)(PMT)

200,000(PV) 360(n) 0.47917(I/Y) (cpt) (FV)
if compounded monthly => 5.75%/12

### If I know how much the payment is and the length of the loan how can I calculate the percentage I am paying?

A=P((1-(1+r)^(-n))/r, where A is the present value of the annuity, or the amount of the loan, P is the periodic payment, r is the interest rate per period, and n is the number of periods. In this case, I assume the payments are monthly, so n would be 36. You mentioned that you already have A and P. However, solving for r algebraically is not that easy because it is in two places on the right hand side. However, you can make a table and put in interest rates to make both sides equal. Remember to multiply this answer by 12 to get the annual interest rate.

For example, if the payment is \$100, and the amount of the loan is \$2,766.07, and the number of periods is 36, what is the interest rate.

r Calculate Actual Difference
0.010 3010.75 2766.07 -244.68
0.011 2959.42 2766.07 -193.35
0.012 2909.33 2766.07 -143.26
0.013 2860.42 2766.07 -94.35
0.014 2812.68 2766.07 -46.61
0.015 2766.07 2766.07 0.00
0.016 2720.55 2766.07 45.52
0.017 2676.11 2766.07 89.96

You can see from the chart that the value of r of 0.015 makes the difference 0, so the periodic interest rate is 0.015 or 1.5%. We need to annualize this by multiplying by 12 and we get an annual interest rate of 18%.

Good luck,

### I have two BA real estate calculator with the same problem. Each one is slightly off in the calculation. Example. \$100,000 loan 6% rate 30 year term should have a 599.99 payment and when I input this...

\$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].

### Explain the term amortization

The process of paying off a loan through specifically structured periodic payments is known as amortization. Amortized loans are different from other loans due to the way the amount and the structure of each payment is determined.

mortgage payments are a common form of amortized loans, and interestingly enough, both the term mortgage and the termamortization find their meaning in the same root word "mort." This term means to deaden or kill, as in to "kill off" or eliminate the loan a bit at a time, via regular payments.
