This spreadsheet-style trading calculator is designed to take the guesswork out of position sizing and trade planning. By entering a fixed dollar risk (for example, $100), the calculator instantly determines the exact number of shares to buy based on your stop loss or a percentage amount.

It automatically calculates:

Proper share size based on your determined risk amount

Stop loss placement

Target exit price

Profit targets based on your chosen risk-to-reward ratio

You can customize your own profit targets or use preset ratios like 1:1, 2:1, 3:1, and more. As soon as you adjust your inputs, all values update instantly, making it extremely fast and easy to use.

This share size calculator helps traders stay consistent, manage risk properly, and avoid overtrading. By removing manual math and second-guessing, it saves a ton of time and eliminates confusion—so you can focus on executing high-quality trades with confidence.
