The Power of Compound Interest
Compound interest means you earn interest on your interest — not just your original investment. Over long time periods, this creates exponential growth. A $10,000 investment at 7% p.a. doubles every ~10 years to $20k, then $40k, then $80k.
Adding regular contributions supercharges this effect. Even $200/month added to a $10,000 investment at 7% for 30 years produces over $260,000 — from just $82,000 actually invested.
📌 Key insight: Starting early matters far more than starting big. 10 years of compounding can’t be replaced by doubling your investment later.
