📐 How We Calculate This

We use the compound interest formula: A = P(1 + r/n)^(nt), where P is principal, r is the annual rate, n is compounding frequency, and t is time in years. For retirement projections, we factor in inflation-adjusted returns using historical S&P 500 data from NYU Stern.

Past performance does not guarantee future results. Actual investment returns vary based on market conditions, fees, and asset allocation. Consult a licensed financial advisor for personalized planning.
