Understanding Compound Growth
Compounding is interest on interest, and return on return. It is powerful over decades — and indifferent to impatience.
Compound growth means the return you earn is itself put back to work. A ₦10,000 contribution that remains invested can, over many years, earn returns on both the original amount and on prior gains.
The mathematics is simple; the behaviour is not. Compounding requires time, reinvestment, and the willingness to leave capital untouched through dull months and noisy ones.
It is not magic, and it is not linear in the short run. Markets do not compound at a smooth advertised rate. Drawdowns interrupt the curve. Fees and inflation quietly reduce what you actually keep.
A cohort's monthly rhythm is a compounding habit: the same amount, the same date, for the length of the cohort. The habit is the point. Any growth on top of contributions is uncertain.
A useful discipline: judge a plan in years, not weeks. Do not confuse a six-month demo chart with a completed compounding story.
