Free Position Size Calculator with Target Price
Our Position Size Calculator helps traders determine the exact number of shares or contracts to buy based on account size, risk percentage, entry price, stop loss, and desired risk-reward ratio. Proper position sizing is the foundation of professional trading and long-term capital protection.
Unlike basic calculators, our tool not only calculates the correct position size, but also provides a ready-to-use target price based on your selected reward multiple. This allows you to enter trades with a complete risk management plan.
Why Position Sizing Is Critical in Trading
Many traders focus heavily on strategy but ignore risk management. Without proper position sizing, even profitable systems can fail due to oversized losses. Professional traders typically risk no more than 0.5% to 1% of their total capital per trade.
Limiting risk to 0.5–1% helps:
- Protect trading capital during losing streaks
- Reduce emotional decision making
- Maintain long-term consistency
- Prevent large drawdowns
- Improve psychological discipline
How This Position Size Calculator Works
The calculator uses the standard professional formula:
Position Size = (Account Size × Risk %) ÷ (Entry − Stop Loss)
After calculating the number of shares, it automatically computes your target price using the selected risk-reward ratio. This means you instantly know:
- Exact number of shares to buy
- Total amount at risk
- Target price based on R-multiple
- Structured trade plan before entry
Example
If your account size is ₹10,000 and you risk 0.5% per trade, your maximum risk is ₹50. If you enter at ₹100 with a stop loss at ₹95, your risk per share is ₹5. The calculator will suggest buying 10 shares. If you choose a 1:5 risk-reward ratio, your target price will be ₹125.
