# How to Calculate Net Present Value (NPV) on a TI-83 Calculator

Net Present Value (NPV) is a crucial financial analysis tool used to assess the profitability of long-term investments, considering the time value of money. Calculating NPV allows investors to determine the present value of future cash flows, enabling them to make informed investment decisions.

1. Step 1: Press the APPS Button
• Locate the APPS button on your TI-83 calculator, typically found at the top-left corner.
2. Step 2: Select the Finance Option
• Use the arrow keys to navigate through the menu until you see the “Finance” option. Press ENTER to select it.
3. Step 3: Navigating to the NPV Function
• Scroll down through the Finance menu using the arrow keys until you find the “NPV” option. Press ENTER to access the NPV function.

## Entering Required Inputs

1. Step 1: Understanding the Inputs
• The NPV function requires three inputs:
• Rate: The discount rate or desired rate of return, entered as a percentage.
• Initial Outlay: The initial cost or investment of the project, entered as a negative value.
• Cash Flows: The cash flows for each period, entered as a list enclosed in curly braces {}. Separate each cash flow with a comma.
2. Step 2: Entering the Rate
• Enter the discount rate as a percentage. For example, if the rate is 10%, enter 10.
3. Step 3: Entering the Initial Outlay
• Enter the initial outlay as a negative value. For example, if the initial investment is \$10,000, enter -10000.
4. Step 4: Entering the Cash Flows
• Enter the cash flows for each period as a list enclosed in curly braces {}. Separate each cash flow with a comma. For example, if the cash flows for years 1 to 5 are \$1,000, \$2,000, \$3,000, \$4,000, and \$5,000, enter {1000, 2000, 3000, 4000, 5000}.

## Calculating the NPV

1. Step 1: Pressing Enter
• Once you have entered all the required inputs, press ENTER to calculate the NPV.
2. Step 2: Viewing the Result
• The result of the NPV calculation will be displayed on the screen. A positive NPV indicates a profitable investment, while a negative NPV suggests a potential loss.

## Approximating IRR on the TI-83 Calculator

• The TI-83 calculator does not have a built-in Internal Rate of Return (IRR) function. However, you can use trial and error or other methods to approximate the IRR.

### Conclusion

• Calculating NPV using the TI-83 calculator involves accessing the Finance menu, entering the required inputs (rate, initial outlay, and cash flows), and pressing ENTER to obtain the result.
• NPV is a valuable financial analysis tool that helps investors assess the profitability of long-term investments by considering the time value of money. A positive NPV indicates a profitable investment, while a negative NPV suggests a potential loss.
