Questions courantes sur Calculateur d'Intérêts Composés
La capitalisation quotidienne offre les meilleurs rendements, suivie de la mensuelle, trimestrielle et annuelle. Cependant, la différence est petite ; par exemple, 0,000 à 5% sur 10 ans augmente à 6,487 avec une capitalisation quotidienne et 6,289 avec une capitalisation annuelle, donc le taux d'intérêt est plus important que la fréquence de sa capitalisation.

Methodology & Sources
Our compound interest calculator uses the standard compound interest formula with advanced features including Monte Carlo simulation, fee modeling, and historical backtesting.
Historical Market Returns
The S&P 500 has averaged approximately 10% annual returns over the past century (1926-2023).
Monte Carlo Simulation
Uses Box-Muller transform to generate normally distributed returns with historical volatility (~15% std dev for stocks).
Fee Impact
Compares your fees against Vanguard (0.05%) and typical managed funds (1%). Even small fee differences compound to massive losses over decades.
Disclaimer
This calculator provides educational projections only. Actual investment returns vary and past performance doesn't guarantee future results. Market volatility, fees, taxes, and other factors can significantly impact real-world returns.
