Frequently Asked Questions

Find Quick Answers

What is IWAA (Investment Weighted Average Annual Return)?

IWAA is a financial metric that calculates the average annual return on an investment, weighted by the time value of money. It considers when cash flows occur during the investment period and discounts them to present value using a specified discount rate.

How is IWAA different from simple ROI?

Simple ROI doesn't consider the time value of money or when cash flows occur. IWAA accounts for these factors by discounting future cash flows, making it a more accurate measure of investment performance over time.

What discount rate should I use?

The discount rate represents your required rate of return or opportunity cost. Common choices include your company's cost of capital, a risk-adjusted rate based on project risk, or a benchmark rate like the weighted average cost of capital (WACC).

What does a positive NPV mean?

A positive Net Present Value (NPV) indicates that the investment is expected to generate more value than it costs, considering your discount rate. This generally means the investment is financially worthwhile.
