The Power of Compound Interest

Historically, the premium baseline for diversified global equities (such as the S&P 500) has hovered between 7% and 10% annualized (unadjusted for inflation) when averaged over multiple decades. High-yield savings accounts and standard government bonds generally offer safer, lower-volatile yields of 2% to 5% depending on prevailing central bank rates and current economic cycles.

Compounding frequency determines how often your earned interest is added back to your principal to begin earning interest of its own. Transitioning from annual to monthly compounding means interest is applied 12 times a year instead of once. While this accelerates overall growth velocity, the impact is further reinforced by making consistent monthly contributions, expanding your base investment pool continuously.
