Did Albert Einstein really say this about compound interest?
“It's the eighth wonder of the world. He who understands it, earns it. He who doesn’t, pays it.”
Whether he said it or not, the message is spot on.
🔹 Compound vs. Simple Interest
Simple Interest: Earns on the original amount only.
Compound Interest: Earns on your original amount plus prior interest.
The difference is massive over time especially with long-term savings, mortgages, or investments.
🔸 Real Life Example
A $500,000 mortgage at 7% over 30 years = $697,546 in interest 😳
That’s compound interest working against you.
But small extra payments can flip the script:
+$50/mo = save $34,575 and pay off 13 months early
+$100/mo = save $66,067 and pay off 25 months early
🔹 Compound Interest & Investing
By reinvesting dividends in stocks, ETFs, or mutual funds, you’re putting compounding to work for you.
Over time, this snowballs your wealth. More shares mean larger future dividends.
⚠️ But be smart: Investments carry risk. Share values fluctuate and dividends aren’t guaranteed.
Still, compounding remains one of the most effective tools for long-term growth.
