Why XIRR Matters for Your PortfolioXIRR is the gold standard for tracking personal investment performance because real-world investing is messy.
Accounts for Timing: It recognizes that depositing $10,000 in 2010 has a completely different impact on your returns than depositing $10,000 yesterday.

Tells the True Story: It answers the ultimate question: "What annualized interest rate did my average invested dollar actually earn?"
