Your real return, not a flattering one
Most brokers show you a time-weighted return β a number that ignores when you actually put money in. Portfellow calculates money-weighted return (XIRR) instead, which accounts for the exact timing and size of every deposit and withdrawal. It's a more honest answer to 'how am I actually doing?'
You're not stuck with one method either β switch between XIRR, CAGR, or a simple linear return depending on what you're trying to understand.
