Stop Loss & Take Profit Calculator: See Your Full Trade Picture Before You Click Buy
Enter your entry, stop loss, take profit, and shares to see gross and net P&L, fee impact, R:R ratio, and account risk % — all in one place. Know exactly what you stand to gain or lose before every trade.
Gross Gain = |Target − Entry| × Shares
Gross Loss = |Entry − Stop| × Shares
Fees = Fee per trade × 2 (entry + exit)
Net Gain = Gross Gain − Fees
Net Loss = Gross Loss + Fees
Net R:R = Net Gain ÷ Net Loss
Fees reduce your gains AND increase your losses. On small positions, fees can significantly degrade your effective R:R ratio.Next Step: After the trade, review your actual results with our Trade Profit/Loss Calculator.
How to Use This Calculator
Select Long or Short
Your trade direction determines how the calculator validates stops and targets.
Enter Entry, Stop Loss, and Take Profit
These are the three defining prices of your trade. Your stop loss is where you'll exit if wrong. Your take profit is where you'll exit if right. Both should be based on chart levels, not arbitrary numbers.
Enter Your Share Count
How many shares are you trading? This converts per-share values into actual dollar amounts. Required for fee calculations.
Add Account Size (Optional)
Enter your total account balance to see what percentage of your account this trade risks. Professionals keep this under 2%.
Add Trading Fees (Optional)
Select Flat $ (e.g., $4.95 per trade) or % of Trade Value (e.g., 0.1%). The calculator applies fees to both entry and exit — because you pay commission when you buy AND when you sell.
Review the Full Picture
The results show: Net R:R ratio (after fees), gross vs. net P&L comparison, total fee cost, breakeven win rate, account risk percentage, and a visual risk/reward bar. If fees are degrading your ratio, the calculator tells you exactly how much.
Example Scenarios
Example 1: Clean Trade, Minimal Fee Impact
Fee impact: minimal — only reduced ratio by 0.10
Entry: $185 | Stop: $182 | Target: $192 | 100 shares | $4.95 flat fee
Example 2: Fees Wipe Out the Profit
The trade was "right" — price went to target — but fees turned a win into a loss. This is the scenario that shocks beginners. The calculator flags it with a red warning:
"Fees wiped out your entire profit."
Entry: $10.00 | Stop: $9.80 | Target: $10.30 | 20 shares | $4.95 flat fee
Example 3: Account Risk Check
Checking the percentage risk on the total account ensures you aren't sizing too aggressively before placing the trade.
"This trade risks 10% of your total account. Professional traders rarely exceed 2%."
Entry: $100 | Stop: $90 | Target: $120 | 100 shares | Account: $10,000
❓ Frequently Asked Questions (FAQ)
What is a stop loss and take profit calculator?
A stop loss and take profit calculator instantly shows optimal exit levels for a trade based on your entry price, risk tolerance, and desired reward. It tells you where to place stop loss and take profit orders to manage risk and secure gains.
Why is calculating stop loss and take profit important?
It prevents emotional trading and ensures consistent risk management. By defining exit points in advance, you protect your capital from large losses and lock in profits when the market moves in your favor.
How do you calculate stop loss?
Stop Loss Price = Entry Price – (Risk Amount ÷ Position Size) for long trades
Example: Buy 100 shares at $50, risk $200 → Stop Loss = 50 – (200 ÷ 100) = $48.
How do you calculate take profit?
Take Profit Price = Entry Price + (Reward Ratio × Risk per Trade ÷ Position Size) for long trades
Example: Entry $50, risk $2 per share, reward ratio 2:1 → Take Profit = 50 + (2×2) = $54.
Can this calculator work for short trades?
Yes. For short trades:
Stop Loss = Entry Price + (Risk Amount ÷ Position Size)
Take Profit = Entry Price – (Reward Ratio × Risk per Trade ÷ Position Size)
How does risk/reward ratio affect stop loss and take profit?
Higher reward ratios move take profit further from entry while keeping stop loss fixed. This allows traders to target bigger gains while limiting losses according to risk rules.
Is the stop loss / take profit calculator accurate?
Yes, mathematically it’s precise based on your inputs. Accuracy depends on correct entry price, position size, and chosen risk/reward ratio. Market slippage or sudden volatility can affect actual execution.
How does this calculator help traders?
It helps traders define clear exit points, enforce risk management, and plan trades ahead of time. This prevents emotional decisions and supports consistent profitability.
Can it integrate with other calculators?
Yes. It works well with position size and profit/loss calculators. Together, they allow full trade planning: size the position, set stop loss/take profit, and see potential net profit or loss.
Why should traders use this calculator before placing trades?
To protect capital, maximize gains, and trade with discipline. Predefined exits reduce emotional mistakes, enforce strategy rules, and improve long-term trading performance.
