IRR Calculator - A Complete Guide

The **Internal Rate of Return (IRR)** helps evaluate the profitability of an investment by determining the **annualized rate of return** on a series of cash flows.

How is IRR Calculated?

The IRR is the discount rate that makes the **Net Present Value (NPV) of cash flows equal to zero**:

NPV = ∑ (Ct / (1 + IRR)^t) = 0

Where:

  • **Ct** = Cash inflow or outflow at time period **t**
  • **IRR** = Internal Rate of Return
  • **t** = Time period

Example Calculations

Example 1: An investment of **$1,000** with returns of **$300, $400, $500, and $600** over 4 years.

IRR = **18.49%**

Example 2: An investment of **$5,000** with returns of **$2,000, $2,500, $3,000** over 3 years.

IRR = **22.63%**

Use this **IRR Calculator** to analyze your investments and make informed financial decisions.
