Click APPS and then ENTER for Finance and then ENTER again for the TVM Solver. There you can input the PV, PMT, i, etc.

"ComPuTe". On TI financial calculators you have to press the CPT button before pressing the button for the value you're solving for. (N, I, PV, PMT, or FV). On an HP calculator, you just press the N-I-PV-PMT-FV button without making any entry in order to solve for the desired value.

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?

Viola. The initials TVM stand for Time-Value-Money; it's a widely used tool throughout financial mathematics. If you are looking to deal with annuities, bonds, present value equations, future value equations, or even certain stocks then you will want to use the TVM app within your TI-84.

When you go into that menu screen you will see about 10 input lines; and despite how you're being taught you'd be best off using only five (from a mathematical & conceptual standpoint). The backbone of the TVM is the time-zero equation of value. So, all you want to be touching is the N, I/Y, PV, PMT, and FV keys.

Background on TVM:

N = Number of intervals

I/Y = Effective Interest Rate Per Interval (5% is .05 but the computer wants it entered as 5.0)

PV = The Present Value

PMT = Recurring Payment (either deposit or withdrawal)

FV = Future Value

There are like 3 other inputs that I encourage you to ignore (in exchange for learning exactly what's going on within this application).

NOTE: You MUST make your effective interest term match your number of intervals. For example, an annuity with monthly payments for 5 years with a monthly effective interest rate of 2% would need an N value of 60 (which is 12 months per year times 5 years for a total of 60 months).

There's more that could be said, but I think this should help you find the PV of an annuity.

Thirty year mortgage for $200,000, 8% annual interest. What is the monthly payment?

Press the APPS key. Select "Finance". Select "TVM_Solver..." For N enter 360 (30 years of 12 months). For I% enter 8. For PV enter 200000. For FV enter 0. For P/V and C/V enter 12 if they're not already so. Select "END" on the last line. Move up to the PMT line and press ALPHA [SOLVE] (ALPHA ENTER). You should get a payment amount of $-1467.53 (the negative sign indicates what you pay out).

I get 6.085%. Make sure the fv and pmt are of opposite signs. You're either making annual payments and getting a lump sum back at the end, or receiving annual payments and then paying it all back in a lump at the end. Either way, the money is moving in opposite directions.

Check to make sure you have the proper value set for payments-per-year.

Press APPS and select the Finance app. Select the TVM Solver.

Enter -4000 for PV, 0 for PMT, 6000 for FV. Be sure you use the (-) key for PV, not the - key. P/V and C/Y should both be 1 and PMT should be END.

If you want 5% annual interest compounded month, enter 5/12 for I%. If you simply want 5% annual interest, enter 5 for I%. Go to N and press ALPHA ENTER to see the number of periods (months or years according to what you entered earlier in this paragraph).

Press the APPS key and select Finance. If there is no Finance entry, then you need to load the Finance app, which you can get from the calculator CD or download from http://education.ti.com

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!
