The loan
The interest
$5,000.00 borrowed at 8% a year for 90 days costs $100.00 in interest. The position must rise 1.00% just to pay it.
- Each day and month
- $1.11 a day, about $33.33 a month, $400.00 a year.
- On your own money
- $5,000.00 of the $10,000.00 is yours, so the interest is 2.00% of it over the 90 days.
The interest for longer holds, and the rise the position and your own money need to cover it.
| Days | Interest | Rise needed | Of your money |
|---|---|---|---|
| 30 | $33.33 | 0.33% | 0.67% |
| 90 | $100.00 | 1.00% | 2.00% |
| 180 | $200.00 | 2.00% | 4.00% |
| 365 | $405.56 | 4.06% | 8.11% |

Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

The loan costs money every day, win or lose
Buying 10,000 of stock with 5,000 of your own money and 5,000 borrowed at 8% costs about 100 in interest over three months, so the stock must rise 1% before the trade makes anything. Hold a year and that becomes about 4%, or about 8% of your own money. The interest is charged whether the price goes up or down.
