The Power of Compound Growth
Compound interest is often called the "eighth wonder of the world." In trading, it means reinvesting your profits to grow your position sizes, leading to exponential account growth over time.
Why Compounding Works
- Month 1: 5% of $10,000 = $500 profit → Balance: $10,500
- Month 2: 5% of $10,500 = $525 profit → Balance: $11,025
- Month 3: 5% of $11,025 = $551 profit → Balance: $11,576
- And so on... each month's profit is larger than the last
Reality check: These projections assume consistent returns, which rarely happens in trading. Losses, drawdowns, and emotional mistakes will impact your actual growth. Use this calculator for motivation and goal-setting, not as a guarantee.
Keys to Successful Compounding
- Consistency — Small, steady gains beat occasional big wins
- Risk management — A 50% loss requires 100% gain to recover
- Patience — The magic happens in year 2, 3, and beyond
- Don't withdraw early — Let profits compound
Projections are nice. What's your actual compound rate?
