$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].

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.

What are the Different Types of Mortgages

The world of mortgages can be really confusing. There are so many different types and the terms and conditions vary between lenders and individual customers.

Here is a very basic outline of some of the main types of mortgages that are available.

Fixed-Rate Loans
Fixed-rate loans are loans where the interest rate says the same for the whole duration of the loan (ie 25 years). This type of mortgage is more stable than others as it's not based on market conditions and allows you to budget for your mortgage without the risk of costs rising.

Adjustable-Rate Loans
Adjustable-rate loans have interest rates attached to them that can change based on an index reflecting market changes. Sometimes these kind of mortgages start out with a lower interest rate than fixed-rate loans but the payments can go up or down causing uncertainty to the customer.

Interest-Only Loans
Interest-only loans involve paying only the interest costs that have built up on the loan balance. Usually these interest only payments carry on for a number of years and then the borrower starts to pay for the actual loan amount as well.

When i enter for mortgage payments - 150,000 =PV, 5= I/Y and 360 = P/Y I should get an answer of 805.28 on my new Texas Instruments Calculator I get an answer of 7,500.000177 I don't know how to set up...

You have the number of payments per year set to one, so the calculator is telling you that you will get annual payments of 7500 on your investment. To set the number of payments per year to twelve, press 2nd [P/Y] 1 2 ENTER 2nd [QUIT]. Now pressing CPT [PMT] should give you the monthly payment of 805.28.

Roll To Unknown Interest Rate

Enter the number of payments and press "n". Enter the monthly payment as a negative number and press "PMT." Enter the amount of the loan and press "PV." Press "i" and see the interest rate.

Mortgage payment

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...?

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!

I do not have the directions and need to figure out how to calculate mortgages.

Here is the link to a guide;
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

Hope this helps
