Tips & Best Practices

  • Simple ROI ignores time. CAGR (compound annual growth rate) annualises the same return so multi-year comparisons make sense.
  • 20% over 5 years sounds great, but as CAGR it's about 3.7%/year — below most index funds.
  • ROI doesn't account for risk, tax, or opportunity cost. Use it as one data point, not the only one.
  • For comparing investments with different time horizons, always use the annualised figure.
  • Cost should include everything you spent (initial outlay + fees + maintenance), not just the headline price.
