How Margin Trading Breakeven Is Calculated
Your breakeven on a margin trade equals the sum of interest costs and trading fees, expressed as a percentage of the total purchase. The stock must rise by at least this percentage before you see any profit. Interest accumulates daily, so longer holding periods increase the required gain significantly.
Breakeven % by Holding Period (9% margin rate, 0.10% fees)
| Holding Period | Interest Cost | Breakeven Gain |
|---|---|---|
| 7 days | 0.17% | 0.27% |
| 30 days | 0.74% | 0.84% |
| 90 days | 2.22% | 2.32% |
| 180 days | 4.44% | 4.54% |
Margin amplifies both gains and losses. A 10% stock decline with 2:1 leverage becomes a 20% loss on your equity — before interest. Always know your margin call level before trading, maintain a buffer above maintenance margin, and avoid holding highly volatile positions on margin for extended periods.
