IRR represents Internal Rate of Return.

• A. Internal Return Ratio
• B. Incremental Return Rate
• C. Investment Required Rate
• D. Internal Rate of Return: Gives a percentage of value but ignores scale.

Answer: (D)

IRR is a rate, not a dollar amount. It represents the discount rate at which the project’s net present value of all cash flows equals zero, and it is shown as a percentage. Because it’s a rate, it communicates how efficiently the investment turns cash over time, but it does not reveal how large the investment is—the scale. Consequently, two projects can share the same IRR yet create very different total value in currency if their sizes differ. That limitation is precisely captured by describing IRR as a percentage of value that ignores scale. In practice, you’d also consider the actual dollars created (via NPV) and how large the investment is when comparing projects.
