Question about Texas Instruments TI-83 Plus Calculator

Since there are twelve months in a year, multiply by twelve. For example, a thirty-year mortgage involves 360 months.

Just be sure to divide the interest rate by twelve to match. For example, 6% annually is 0.5% monthly.

Depends on the payments plan. If annually, the yield is 10%; if semi-annually then 5%. Quarterly the yeild is 2.5%. A good site to do the actual calculations is investopedia.com.

Not built-in (the 48 is a scientific calculator, not a financial calculator). But there are plenty of programs and applications for financial calculations. Some of them are:

The 107,186.37 is what the future value would be if the interest per month is 0.58%, which is 6.96% per year. Try the following:

2nd [CLR TVM] 1 2 N 7 I/YR 1 0 0 0 0 0 PV CPT FV

As for rounding, you can change the calculator display to any number of digits (up to a limit, of course) by pressing 2nd [FORMAT] and then a number specifying the number of desired digits after the decimal point or 9 for floating decimal.

Sorry, but that calculator does not have a financial application.

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.

What you've done is calculate the future value after 3 months, not 3 years.

Press 1 SHIFT [P/YR] to set the payments per year to one. Now the FV key should give you 115.76

I get an answer of 366.91 in my 12C as well. You might try either putting in a zero for FV before hitting the [PMT] key, or clearing your registers before doing the problem, as you may be picking up an old value from a previous problem in the FV register.
