# Internal Rate of Return (IRR) **What it is:** IRR is the discount rate that makes the net present value (NPV) of all cash flows from an investment equal to zero. In simpler terms, it's the annualized rate of return you can expect from a project or investment based on its projected cash flows. ## Common Misconception **The misconception:** Many people believe IRR represents the actual annual return they'll earn on their invested capital throughout the project's life. **The reality:** IRR assumes that all interim cash flows generated by the project are reinvested at the same IRR rate. This is rarely realistic. For example, if a project has a 25% IRR, it assumes you can reinvest all cash received at 25%—which may be far higher than available market rates. This reinvestment assumption can make IRR misleading, especially when comparing projects with different cash flow patterns or durations. That's why IRR should be used alongside other metrics like NPV for investment decisions.
