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,

In any order, enter loan amount followed by PV, number of months followed by N, interest rate followed by i. Then press PMT.

The loan seems rather usurious. Are you sure it's not a two-year loan (twenty-four months)? That brings the interest rate down into a reasonable range.

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.

The present value of any future monthly (?) stream of payments stretching some 24 years into the future takes into account the time value of money and depends on the interest rate assumed to apply for each month throughout those 24 years.

There are formulae to calc this for an equal monthly payment and a constant interest rate, over the term but for a variable interest rate you need a spreadsheet.

In the simple case of zero interest assumed throughout the term, present value = current principal balance, but for any positive interest rate, the total present value of the future payment stream is less than the current principal balance.

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
