Stop Loss & Take Profit Calculator
Derive exit prices from a fixed position and a cash risk budget.
How it works
Fixed quantity: this derives prices from your cash budget. It does not choose a technical stop or include slippage and funding.

How the Stop Loss & Take Profit Calculator works
This stop loss and take profit calculator derives two exit prices for a position whose entry and quantity are already fixed. Enter your account balance, the percentage you are willing to lose, a net reward-to-risk ratio and trading fees. The loss at the calculated stop includes both entry and exit fees.
Calculate a stop from the cash risk budget
Cash risk = balance × risk percentage ÷ 100. With quantity q, entry E and fee fraction f, net long PnL at exit P is q × [P × (1 − f) − E × (1 + f)]. Set this equal to minus your risk budget to find the stop. Set it equal to risk × reward-to-risk to find the target. For a short, net PnL is q × [E × (1 − f) − P × (1 + f)].
Example: entry 100, quantity 10, balance 1,000, risk 5% and a 2:1 reward-to-risk ratio. With no fees, the stop is 95 and target 110: the cash loss is 50 and profit 100. With 0.1% on each fill, the stop is approximately 95.1952 and target 110.2102. Fees move the stop closer and the target further away while preserving the stated net amounts. These inputs illustrate the arithmetic; 5% is not a recommended risk allocation.
A cash-based exit and a technical stop answer different questions
This tool does not find support, resistance, volatility or a suitable place for an order. If your strategy already specifies a stop, use position sizing to derive quantity from that stop instead. To evaluate two exit prices you have already selected, use risk/reward. To find an exit from a desired cash profit or ROE, use target price.
A stop order's trigger is not a guaranteed execution price. The calculation assumes a full fill at the displayed price, with the same fee rate at entry and exit, and excludes funding, spread and slippage. Compare the stop against liquidation separately when using leverage.
FAQ
Why is my risk budget too small to produce a stop?
Even exiting at entry incurs entry and exit fees. If your cash budget is no larger than those costs, a losing price move cannot fit inside it. Reduce position size or reconsider the budget rather than treating a profitable exit as a stop.
Does leverage move these stop and target prices?
For a fixed base quantity, leverage changes collateral, not the cash PnL equation. It can cause liquidation before the planned stop, so check the margin requirement separately.
Can it calculate a short stop-loss?
Yes. Select short. A coherent short stop is above entry and its profit target is below entry. An unattainable positive target or stop is rejected.
