Position Sizing Calculator — A Smarter Way to Trade

Most traders don’t lose money because they pick the wrong stock or mistime the market. The real problem is often poor risk management — especially trading with oversized positions.

This is where position sizing becomes essential.

If you’ve ever caught yourself wondering, “How many shares should I actually trade?” — that’s the right mindset. Mastering position sizing is one of the most important steps toward consistent success in the markets.

What is Position Sizing?

Position sizing is the process of deciding the number of shares, lots, or contracts you’ll take on a trade, based on your willingness to risk a specific portion of your trading account.

Professional traders focus on limiting risk first, rather than chasing profits. Here’s the golden question:

💡 “How much am I willing to lose if this trade doesn’t go as expected?”

Once you answer that, determining your position size becomes simple. By calculating position size correctly, you safeguard your capital from the kind of emotional decisions that can wipe out an account.

Why Position Sizing is a Game-Changer

Many traders mistakenly believe that a weak strategy is the main reason for losses. In reality, even a great strategy can fail without proper position sizing.

You can’t control market movements, but you can control the risk on each trade. Smart position sizing helps you:

  • Stay calm during drawdowns.
  • Avoid revenge trading after losses.
  • Focus on long-term consistency.
  • Shield your capital from major setbacks.

This small adjustment can have a huge impact on your trading longevity.

How Our Position Sizing Calculator Simplifies the Process

We’ve designed this calculator to eliminate guesswork from your risk management.

You just need to enter:

Difference between entry and stop-loss = ₹10.

  • Total account balance.
  • Percentage of capital you’re willing to risk.
  • Entry price for the trade.
  • Stop-loss price.

The calculator instantly shows you the correct position size — making sure you never overexpose your account.

Example of Position Sizing in Action

Let’s say:

  • Account Size: ₹1,00,000
  • Risk Per Trade: 1% (₹1,000)
  • Entry Price: ₹500
  • Stop-Loss Price: ₹490

Calculation:

Position Size = Risk Amount / Stop-Loss Difference
Position Size = ₹1,000 ÷ ₹10 = 100 Shares

If this trade fails, you’ll only lose ₹1,000 — staying within your set risk level.

Why Traders Often Fail Without Position Sizing

Most traders don’t fail because of bad predictions, but because they risk too much on individual trades.

Position sizing prevents these common mistakes:

  • Oversizing out of overconfidence.
  • Refusing to exit losing trades.
  • Doubling down after losses.

Proper sizing builds discipline and ensures survival through market volatility.

  • Avoid emotional overtrading.
  • Allow your strategy to perform over time.

Even with a 50% win rate, correct position sizing can lead to long-term growth.
