How do you calculate potential profit or loss before entering a trade?
Calculating Potential Profit or Loss Before Entering a Forex Trade
Before you click "Buy" or "Sell", always calculate your risk and reward first.
Core Formula:Potential Loss (Risk) = Stop Loss distance (in pips) × Pip Value × Lot Size
Potential Profit (Reward) = Take Profit distance (in pips) × Pip Value × Lot Size
1. Decide your risk – Example: You only want to risk $100 on this trade.
2. Set your Stop Loss (SL) – Example: 40 pips away from entry.
3. Choose lot size based on risk:
- Pip value for standard lot (1.0) ≈ $10 per pip (most pairs)
- Pip value for mini lot (0.1) ≈ $1 per pip
- Pip value for micro lot (0.01) ≈ $0.10 per pip
Lot Size = Risk Amount ÷ (SL pips × Pip Value per lot)
Example: Risk $100, SL 40 pips, using 0.1 lots ($1/pip):
Risk = 40 pips × $1 = $40 (safe)
4. Set Take Profit (TP) – Example: 80 pips away.
Potential Profit = 80 pips × $1 = $80
Risk:Reward Ratio = 40:80 = 1:2 (You risk $40 to make $80)
Key Rule:
Never enter a trade without knowing exactly:
- How much you can lose (must be acceptable)
- How much you can gain
- Your risk:reward ratio (ideally 1:2 or better)
Calculate this before every trade. This is part of risk management.
