Compound interest is earning returns on both your original investment and on previously earned returns, causing growth to accelerate over time.
Compound interest is the process of earning returns not just on your original investment, but also on the returns it has already generated. Over time, this creates a snowball effect.
The longer your money compounds, the more dramatic the growth, because each period builds on a larger base. This is why starting early is so powerful, even with modest amounts.
For example, reinvesting dividends or staking rewards rather than spending them lets those earnings generate their own earnings, accelerating wealth accumulation.
Albert Einstein is often quoted, perhaps apocryphally, calling compound interest the eighth wonder of the world. Whether or not he said it, the math is undeniable: time and consistency are an investor greatest allies.
Invest $1,000 at 8% compounded annually. After year one you have $1,080; in year two you earn 8% on $1,080, not just the original $1,000, reaching $1,166. Left untouched, that balance grows to roughly $2,159 after 10 years and about $4,661 after 20 — purely from compounding.
Simple interest is calculated only on your original principal, so it grows in a straight line. Compound interest is calculated on the principal plus accumulated returns, so growth accelerates over time.
Compounding rewards time: the longer your money grows, the more each year builds on a larger base. Starting early means even modest amounts have decades to snowball, which often outweighs investing larger sums later.
