About XIRR

What is XIRR?

XIRR (Extended Internal Rate of Return) calculates the annualized return rate for irregular cash flows occurring at different time periods. Unlike IRR, XIRR can handle cash flows that don't occur at regular intervals.

How it Works

XIRR uses the Newton-Raphson method to find the discount rate that makes the Net Present Value (NPV) of all cash flows equal to zero:

NPV = Σ(CFᵢ / (1 + r)^((dᵢ - d₀)/365)) = 0

Where CFᵢ is the cash flow, r is the XIRR rate, and (dᵢ - d₀) is days between dates.

Key Points

  • Negative values represent outflows (investments)
  • Positive values represent inflows (returns)
  • At least one positive and one negative cash flow required
  • Result is annualized percentage return
  • Higher XIRR indicates better investment performance
