Let's see, 10% interest per year on $100 for one month. That's 10/12 of a percent interest on $100 is $0.83, added to $100 is $100.83 (with a bunch more 3s at the end). Clearly this is the correct answer.

What answer are you expecting? The future value at the end of one year instead of one month?

Make sure you have P/Y set to 1 and BGN/END set to END. With those settings, pressing 9 I/Y 9 2 0 FV 1 0 0 +/- PMT CPT N should produce 7.00 .

Error 5 indicates that no solution exists. In this particular case, you're asking for the interest rate on a savings account that pays you 10,000 now and an additional 20,000 10 years later. (Or a loan where you pay 10,000 now and an additional 20,000 10 years later.)

Either PV or FV should be negative. For example, if you deposit 10,000 in a savings account and withdraw 20,000 10 years later, use -10,000 for FV.

You're entering the interest as a monthly rate. You need to use an annual rate. Instead of .6434 per month, use .6434*12 = 7.7208 for the I/Y value.

It's giving you the correct answer for the problem you've input. When you specified 1 for n, you told it one month. If you specify more digits, you'll see that the answer is 1.00833333.

By default, the calculator works with annual interest rates but counts periods in months.

Hey,

Just found out the answer!

Apparently you can't have both FV and PV positive. Try the calculation with one of them being negative.

You have the payments-per-year set to 12. For this pair of problems, it needs to be set to 1.

Press 2nd [P/Y] 1 ENTER.

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!

You need to have your PV and your PMT be a different sign. Try making your payments negative.

Here is the link to a guide;

http://www.buec.udel.edu/bowersh/finc311_F04/Documents_f04/Quick%20Guide.pdf

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

[CPT] PMT

Hope this helps
