Hi, this is Rob. I'm going to show you how to calculate future value with compounding on the TI-84 Plus CE graphing calculator. Future value is a time value of money problem, also known as a TVM problem. To solve TVM problems on the TI-84 Plus CE, we will use the built-in finance app. To get started, press the apps key located here. The application and window will pop up, and we want the finance app at the top. Press the 1 key or the enter key to access the finance app. Here, we want the first option, the TVM solver (Time Value of Money Solver). Press the 1 key or the enter key. These are all the time value of money variables. I will explain each one. At the top is the number of payment periods over the entire timeframe. If the timeframe is two years, the "n" would be the number of payment periods over those two years. "I percent" is the annual interest rate, also known as APR. Do not convert this into a decimal format. If the annual interest rate is 1.01 percent, then enter it as 1.01. "PV" is the present value. This app uses the cash flow method. Thus, if money is leaving your pocket to fund an account, enter the amount as a negative number. Remember to use the negative sign and not the minus key when inputting this value. If you use the minus key, you will get an error message. "PMT" (payment) is the amount of regular payments being added or withdrawn into or out of the account. For example, if every month you take $100 out of your pocket to fund the account, enter a negative 100 here. "FV" is for future value. This is the variable that we'll be solving. "PPY" is payments per year. It's closely...
