Work out extended irr (xirr) instantly with clear inputs, formula shown and shareable results.
XIRR is the single annual rate that discounts irregularly timed cash flows back to zero. Because money invested later has less time to work, XIRR weights each contribution by how long it was actually deployed — which a simple return cannot do.
XIRR
0 = Σ CFₜ / (1 + r)^(tₜ), with tₜ measured in years
Figures are estimates for planning only. Market returns are not guaranteed, and rates, limits and tax rules change. This is not financial or tax advice — speak to a qualified adviser before acting.
CAGR assumes one investment and one exit. XIRR handles any number of contributions and withdrawals on any dates.
The equation is a polynomial in the rate with no closed-form solution, so bisection or Newton's method is used.
