Pillars of exponential capital growth
Regular contributions
Consistently investing a fixed amount each month beats large, erratic one-off deposits.
Time horizon
Time is the ultimate multiplier; the largest net jumps in wealth occur in the final compounding decades.
Full reinvestment
Keeping dividends and interest invested avoids tax drag and accelerates the compounding snowball.
Strict fee awareness
An ongoing 1% annual management fee can erode over 25% of your final portfolio value over 30 years.
Inflation protection
Compounded investing is the best historical defense to safeguard purchasing power against inflation.
