Stop Loss & Take Profit Calculator — User Guide & Reference
Stop loss and take profit are the two orders that decide when a trade ends, set before the trade begins. This guide explains where to place each, the formula that converts risk into price levels, and walks a worked example.

What stop loss and take profit do
A stop loss is an order to exit when price moves against you by a set amount, capping the loss. A take profit is an order to exit when price reaches a target, securing the profit. Both are decided before entry, which removes the two hardest decisions — when to cut and when to take profit — from the heat of the moment.
Why defining exits first changes everything
Most traders decide entries first and exits whenever the market forces them. Reversing that — defining both exits before entry — turns every trade into a plan with a known worst case and a defined target. That discipline is what separates a rule-based trader from someone reacting to the screen.
Where to place a stop loss
Place the stop where the trade thesis is proven wrong, not at an arbitrary round number. Common anchors are beyond a recent swing, outside a support or resistance zone, or at a volatility-based distance such as a multiple of ATR. The chart decides where the stop belongs; position size decides whether that distance is affordable.
Where to place a take profit
A take profit should sit where the market is likely to reach before reversing — prior resistance, a measured move, or a multiple of the risk distance. The risk-to-reward ratio falls out of the two distances: if the stop is $2 away and the target is $4 away, the trade is a 1:2 setup.
How to use the calculator
Enter your entry price, your risk and profit targets, and your position size. The calculator converts your dollar risk into a price distance and returns the exact stop loss and take profit levels. Check both levels against the chart before committing — if either does not fit the structure, adjust the trade before it exists.
Worked example: a $50 stock with a $150 risk
You want to risk $150 on a trade and are buying a stock at $50 with 100 shares. The risk per share is $1.50, so the stop loss sits at $50 minus $1.50, or $48.50. If you want a 1:2 reward, the target is $3.00 above entry, so take profit sits at $53.00. Both exits are now defined before the order is placed.
Common mistakes
The biggest mistake is placing the stop at a round number instead of where the idea fails. Another is moving the stop further away after price goes against you — that converts a planned small loss into an unplanned large one. And never assume the stop guarantees the exact exit price: gaps and fast moves can fill past it.
Parameters explained
| Parameter | What it means |
|---|---|
| Instrument | The currency pair or symbol being traded, which sets the contract size and pricing. |
| Account currency | The currency your account is denominated in, used for the conversion. |
| Direction | Long or short — flips whether the stop sits below or above entry. |
| Entry price | The price where the position is opened, the reference for both exits. |
| Lot size / shares | The position size that converts a dollar risk into a price distance. |
| Risk / profit amount | The dollar amounts used to derive the stop and target prices. |
Key concepts
Stop loss
An order to exit when price moves against you by a set amount, capping the loss on the trade.
Take profit
An order to exit when price reaches a target, securing the profit.
Risk distance
The price gap between entry and stop, which determines the risk of the trade.
Mistakes traders make
✗ Placing the stop at a round number instead of where the idea fails
✓A stop should go where the trade thesis is proven wrong — beyond a swing or a volatility buffer — not at a psychologically neat price the market ignores.
✗ Moving the stop further away after price goes against you
✓That converts a planned small loss into an unplanned large one. Widen only before entry, never after, and only by shrinking the position.
✗ Assuming the stop guarantees the exact exit price
✓Gaps and fast moves can fill past your stop. Size the position so that even a worse-than-planned fill stays survivable.
When this tool fits — and when it does not
Use it when
- ✓On every trade where you cannot watch the screen continuously.
- ✓When a setup's stop and target can be defined from the chart before entry.
- ✓When you want to compare a trade's risk and reward before committing capital.
Skip it when
- ✗Setting stops so tight that normal noise stops you out on every trade.
- ✗Using a fixed take profit on a momentum trade that should be trailed instead.
- ✗Placing exits without first defining the position size they apply to.
Practical tips that actually help
Anchor the stop to structure, then let size absorb the distance
The chart decides where the stop belongs; the position size decides whether that distance is affordable. Never force a tighter stop just to fit a bigger position.
Predefine the target from the same structure
Use prior resistance, measured moves, or a fixed R multiple. A target with a reason is easier to hold than a number picked at random.
Rehearse the exit before the trade
Knowing both exits in advance removes the two worst decisions — when to cut and when to take profit — from the heat of the moment.

Frequently asked questions
Why set a stop loss at all?▾
A stop loss caps the downside so a single bad trade cannot drain the account, and it removes the need to decide under stress. The exit is already planned before the trade fills.
Should take profit always be used?▾
Not necessarily — many strategies scale out or trail instead. A fixed target is one option, chosen to suit the strategy.
Where should I place a stop loss?▾
Place it where the trade thesis is proven wrong: beyond a recent swing, outside a support or resistance zone, or at a volatility-based distance such as a multiple of ATR.
What happens if the market gaps through my stop?▾
A stop is not a guarantee of the exact price. In a fast move or gap, the fill can occur beyond your stop, so the realized loss can be larger than planned.
Do I need both orders on every trade?▾
A stop loss is near-universal for risk control. A take profit depends on your style: fixed-target traders use one, while trend-followers may trail a stop instead and let winners run.
How are stop and target related to risk-to-reward?▾
The two distances define the ratio. A stop $2 away and a target $4 away is a 1:2 trade, breaking even at a 33% win rate. The calculator makes that relationship visible.
Why does my stop distance change when I change the risk amount?▾
Because the calculator works back from the dollar risk you set. A larger risk budget allows a wider stop for the same position size; a tighter budget forces the stop closer to entry.
Should I move my stop to breakeven once the trade is profitable?▾
Many traders move the stop to breakeven once price has moved favorably, turning a losing trade into a risk-free one. But moving it too early can stop you out before the move develops — it is a judgment call, not a rule.
