Stopped Out: How to Calculate Your Real Crypto Profit After a Stop-Loss Exit (Slippage Included)

A stop-loss is supposed to cap your downside. You pick a price, set the order, and walk away knowing the worst case. Then the exit fills and the loss is bigger than planned. Nobody made a mistake — the gap between your trigger price and your actual fill price did the damage, and the fees quietly added to it.

This is the number most traders never calculate properly: not the loss they intended, but the loss they actually took — and it changes your remaining capital and your break-even price.

Why Your Stop-Loss Price Is Not Your Exit Price

On most exchanges, a standard stop-loss becomes a market order once the trigger price is hit. It does not guarantee execution at that price — only execution as soon as possible after it. In a fast market, the order book thins in seconds and your order fills at whatever prices are available. That gap is slippage.

Slippage is worst when you most want protection: sharp sell-offs, thin weekend liquidity, and cascading liquidations. A stop set 7.5% below entry can easily fill 8% or 9% below it.

Key takeaway: Your stop-loss trigger price is a plan, not a result — always calculate your loss from the actual fill price, not the price you set.

The Formula: Planned Loss vs Actual Loss

The calculation has four parts — skipping any one understates your loss:

Step 1: Your true cost basis

Position size × entry price, plus the buy fee. That total — not the headline purchase price — is what you need to recover.

Step 2: Your planned exit

Position size × stop-loss trigger price, minus the sell fee. This is the best case if the stop works perfectly.

Step 3: Your actual exit

Position size × the real average fill price from your trade history, minus the actual sell fee. This is the number that counts.

Step 4: The slippage cost

Planned net proceeds minus actual net proceeds. That difference is what slippage cost you — money that is gone whether or not you re-enter.

Worked Example: 0.5 BTC Stopped Out

All figures below are illustrative, using a 0.1% fee on each side: you buy 0.5 BTC at $80,000, set a stop-loss at $74,000, and the order fills at $73,400 during a sharp dip.

Slippage is $600 per coin ($74,000 − $73,400), or $300 on 0.5 BTC — almost exactly the $299.70 gap, the 30-cent difference coming from the slightly lower sell fee. The break-even re-entry price is where your remaining $36,663.30 buys back the same 0.5 BTC after the buy fee: 0.5 × $73,253.35 = $36,626.68, plus a $36.63 fee, equals $36,663.30. Re-enter above it and you hold less than 0.5 BTC.

How to Reduce the Damage Next Time

You cannot eliminate slippage, but you can shrink it. A stop-limit order caps your worst fill price — at the risk of not filling at all in a crash, which is worse. For large positions, splitting the exit or using limit orders, as covered in our guide to limit orders vs market orders and slippage, usually beats a single market dump. If your exit was forced by leverage, our partial liquidation guide shows how the remaining position changes the picture.

Position sizing matters more than order type: a stop risking 2% of your account survives a $300 slippage surprise; one risking 20% does not. Fix your maximum dollar loss before you enter, then work backward to position size.

Key takeaway: Size every position from the loss you can afford after slippage, not the loss at your trigger price — the fill, not the plan, is what your account feels.

Run the Numbers Before You Re-Enter

Before you jump back in, plug your actual fill price, both fees, and your remaining capital into a crypto profit calculator: check how much coin your capital actually buys, and what price the new position must reach to recover the loss.

Conclusion

A stop-loss does its job when it gets you out — but the price on your plan and the price in your account are rarely the same. Slippage of just $600 per coin turned a planned $3,077 loss into a real $3,376.70 loss here, with a break-even re-entry price of $73,253.35. Calculate from actual fills, include every fee, and size for the worst fill.
