Internal Rate of Return (IRR) Calculator

IRR Calculator

This free **IRR calculator** helps you find the **internal rate of return** of your investments. Enter your initial investment and a series of cash inflows to calculate the IRR percentage.

Initial Investment ($) Cash Inflows (comma separated, e.g. 3000,4000,5000)

How IRR Calculator Works

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

Formula (simplified): Solve for r in:

0 = -Initial Investment + Σ [ Cash Flow / (1+r)^t ]

Example:

Initial Investment = $10,000
Cash inflows = $3,000, $4,000, $5,000

• IRR ≈ 15.2%

Note: This **investment analysis calculator** uses an iterative method to approximate IRR. Results are for estimation only.
