Investing
Compounding
Also known as: Compound interest
When your returns start earning their own returns, making money snowball over time.
Compounding is earning returns on your returns. Year one you earn on your money, year two you earn on your money plus last year's gains.
It starts slow and feels boring, then goes vertical in the later years. That is why starting early beats investing more later.
It is the single most important idea in personal finance. Time in the market is the real cheat code.
For example
₹10,000/month at 12% for 30 years becomes about ₹3.5 crore, and over half of that is created in just the final 10 years.
