Data

| The interest rate can not exceed 12%. |

Type of Deposit
Click on the down arrow and select the type of deposits. The selections include:
•Level Deposits: Deposits to the account are the same for all years.
•Annually Increase by Percent: Deposits increase by a percent each year.
•Annually Increase by Dollar: Deposits increase by a dollar value each year.
•Percent of Paycheck: This will change the prompts below to ask for the current paycheck value and the annual raises.
| Note: | When the Percent of Paycheck method is selected as Type of Deposits, the prompts will appear differently than what is discussed below. However, the calculation is similar in nature, and the prompts are self explanatory. |

Amount of Each Deposit
Enter the initial value of the deposit. If a Type of Deposit method was selected other then Level Deposits then the deposits will increase after the first year.
