Forex Risk Reward Calculator: Position Sizing Made Easy

Risk Disclaimer: Trading forex and CFDs carries a high level of risk to your capital. According to industry data, 70-80% of retail investor accounts lose money when trading CFDs. You should consider whether you can afford to take the high risk of losing your money. This content is for educational purposes only.

What Is Risk-Reward Ratio?

Risk-reward ratio compares the potential loss on a trade to the potential profit. A 1:2 risk-reward means you risk Rs 1,000 to potentially make Rs 2,000. This single metric determines whether your trading strategy can be profitable over hundreds of trades.

With a 1:2 ratio, you only need to win 34% of your trades to break even. With a 1:3 ratio, you need just 25%. This is why professional traders obsess over risk-reward before entering any position — it matters more than win rate.

Calculating Risk-Reward

Risk = Entry Price - Stop Loss (for long trades)

Reward = Take Profit - Entry Price

Risk-Reward Ratio = Reward / Risk

Example: You buy EUR/USD at 1.0850 with a stop loss at 1.0820 and take profit at 1.0910. Risk = 30 pips. Reward = 60 pips. Ratio = 60/30 = 1:2.

Always calculate this before entering a trade. If the ratio is below 1:1.5, skip the trade unless your strategy has a proven win rate above 60%.

Position Sizing Formula

Position Size = (Account Risk) / (Stop Loss in Pips x Pip Value)

Account Risk = Account Balance x Risk Percentage. If your account is $1,000 and you risk 2%, your account risk is $20.

Pip Value depends on lot size and pair. For EUR/USD, a standard lot (100,000 units) has a pip value of $10. A mini lot is $1. A micro lot is $0.10.

Example: $1,000 account, 2% risk ($20), 40-pip stop loss. Position Size = $20 / (40 x $0.10) = 5 micro lots (0.05 lots).

Understanding Lot Sizes

Standard lot: 100,000 units. 1 pip = $10 for USD pairs. Requires significant margin. Not recommended for accounts under $10,000.

Mini lot: 10,000 units. 1 pip = $1. Good for accounts of $1,000-$10,000.

Micro lot: 1,000 units. 1 pip = $0.10. Ideal for accounts under $1,000 or Rs 84,000. Both Exness and XM support micro lots.

Practical Examples for INR Accounts

Scenario 1: Rs 50,000 account on Exness. Risk 1% = Rs 500. Trading EUR/USD with a 30-pip stop. At current rates, Rs 500 = approximately $6. Position size = $6 / (30 x $0.10) = 2 micro lots (0.02 lots).

Scenario 2: Rs 1,00,000 account on XM. Risk 2% = Rs 2,000 ($24). Trading GBP/USD with a 50-pip stop. Position size = $24 / (50 x $0.10) = 4.8 micro lots. Round down to 0.04 lots.

Always round down, never up. Rounding up increases your risk beyond your intended percentage.

Your risk-reward ratio only holds if execution is clean. A 1:2 risk-reward with 1 pip of slippage becomes 1:1.7 on a 5-pip stop. Exness execution under 25ms means your planned ratios survive contact with the market.

Frequently Asked Questions

What risk-reward ratio should I aim for?

Aim for a minimum 1:2 risk-reward ratio. This means for every Rs 1,000 you risk, your potential profit should be at least Rs 2,000. With a 1:2 ratio, you only need to win 34% of trades to be profitable.

How do I calculate position size in lots?

Use the formula: Lots = (Account Risk in $) / (Stop Loss in Pips x Pip Value per Lot). For micro lots on EUR/USD, pip value is $0.10. So for $20 risk and 40-pip stop: $20 / (40 x $0.10) = 5 micro lots.

Should I risk 1% or 2% per trade?

Beginners should start with 1% risk per trade. As you develop a proven track record with a consistent win rate, you can increase to 2%. Never risk more than 2% on a single trade regardless of experience.

Does position sizing change for different pairs?

Yes. Pip values differ across currency pairs. USD/JPY and EUR/USD have different pip values. Always calculate the specific pip value for the pair you are trading before sizing your position.
