Internal Rate of Return (IRR) - 15 Years

This calculates the internal rate of return (IRR) of an income stream. Enter the initial investment as a negative number (e.g., – 7000). Enter the 15 periodic cash flows.

You do not have to use all 15 cash flow periods. For instance, you can use the first 11. However, you must enter a zero for every blank cash flow.

Use no commas nor percentage or dollar characters.



The IRR is for irregular cash flows. If the cash flows are uniform, you can use the normal discounted cash flow functions of a financial calculator.

Don't forget to include the reversion (return of capital), if there is one, with the last cash flow.
