Guide d'utilisation complet
What is ROI and CAGR?
ROI (Return on Investment) measures total return as a percentage of what you put in. CAGR (Compound Annual Growth Rate) is the smoothed annual return that accounts for compounding over time. This calculator projects growth with monthly contributions, then applies inflation and tax adjustments so you see both nominal and real outcomes.
