Why your stop distance is the foundation of every risk decision
Every risk decision in a trade — position size, dollar risk, reward-to-risk ratio — starts with one number: how many pips away is your stop? Get that number wrong (or skip calculating it and just eyeball it) and every downstream calculation is wrong too. This calculator gives you the exact pip distance between your entry and stop, so the position size calculator further down the risk chain has a real number to work with.
Enter your entry and stop-loss prices, pick the pair type so the pip size is correct, and the calculator returns the distance in pips and in raw price. It also flags if your stop is on the wrong side of entry for the direction you selected — an easy mistake to make when you're moving fast on a live chart.
The reason this number matters more than any other on the trade: a stop that's set too tight is a guaranteed stop-out that wipes out the trade before the setup has a chance to work. A stop that's set too wide inflates the dollar risk on every trade, forcing the position size down to a level where a win is barely worth the emotional cost of taking it. Either extreme breaks the strategy. The sweet spot is the smallest stop that gives the trade room to breathe, placed at a level where the trade thesis is genuinely invalidated.
The most common beginner mistake is treating the stop as an "insurance policy" against losses and placing it 5-10 pips away to "save money if it goes wrong." In practice, this kind of tight stop gets triggered by routine market noise dozens of times before any of the trades would have hit their target. The win rate collapses, the trader concludes the strategy doesn't work, and the account bleeds. The fix is almost always a wider stop at structure, not a tighter one. Use this calculator to know exactly what that wider stop costs in pips, then the position size calculator to keep the dollar risk constant.
The three numbers that drive your stop
- Pip size matters — standard pairs use 0.0001 per pip, JPY pairs use 0.01, so the same price gap means a very different number of pips depending on the pair.
- Stop distance drives position size — a wider stop means a smaller position for the same dollar risk, and vice versa.
- Direction matters — a stop above entry on a buy, or below entry on a sell, is a setup error, not a small detail.
