Frequently asked questions
What is a Position Size Calculator?
How Does a Position Size Calculator Help in Trading & Investing?
A Position Size Calculator helps you quickly calculate your risk exposure when placing a trade or investment.

You have £10,000 in a trading account and want to risk 10% of that account on the stock. You will need to understand if you want to use leverage, what that leverage is, what thee current price of the stock is currently, what that corresponds to in your trade or investment, and how many shares to buy. All of this can be done with a push of a button on Position Size Calculator.
