The Magic of Compounding in Trading
Albert Einstein reportedly called compound interest the"eighth wonder of the world." In trading, compounding is the process of generating returns not just on your original starting capital, but on the accumulated profits from previous trades.
Instead of withdrawing your profits, you leave them in your account. As your account grows, you can trade larger lot sizes while risking the exact same percentage of your account, resulting in exponential growth.
Your Projected Growth Curve
Based on your inputs above, here is how your balance accelerates over the first 24 periods:
Simple vs. Compound Interest
To understand why compounding is so powerful, let's compare it to Simple Interest. Imagine you start with $10,000 and make a 10% return every year for 10 years.
- Simple Interest: You make $1,000 per year. After 10 years, you made $10,000 in total. Final balance = $20,000.
- Compound Interest: You make 10% on your new balance each year ($1,000 the first year, $1,100 the second, $1,210 the third). Final balance = $25,937.
That is nearly $6,000 in extra"free" profit simply by leaving the money in the account to grow.
The Rule of 72
Want a quick way to estimate how long it will take to double your trading account without a calculator? Use the Rule of 72.
Simply divide 72 by your expected periodic return percentage. The result is the number of periods it will take to double your money.
