Position Size Calculator

Position size calculator — a free Forex tool that lets you calculate the size of the position in units and lots to accurately manage your risks. It works with all major currency pairs and crosses. It requires only few input values, but allows you to tune it finely to your specific needs. All you need to do is fill the form below and press the "Calculate" button:

  • Account Currency
  • required
  • required
  • required
  • Currency pair
  • required
Risk Ratio, %Money, USD  

The form does not calculate position size for oil, gold (XAU/USD), silver (XAG/USD), and other commodities as their contract specifications (namely, lot size) differ significantly between brokers. Please use our MetaTrader expert advisor to assess position volumes for such assets (see below).

Calculating the amount you can risk is very important if you carefully follow a money management strategy. I recommend doing it every time you manually open a new Forex position. It will take a minute of your time but will save you from losing money you do not want to lose. Position size calculation is also a first step to the organized Forex trading, which in its turn is a definite property of professional Forex traders.

Consider using brokers with micro or lower minimum position size. Otherwise you might find it difficult to use the calculated value in actual trading orders.

The importance of a thorough position size calculation process is stressed out in many influential Forex books. Sizing a position should be done in line with setting the right stop-loss and take-profit levels. It will be difficult to lose all the account's money if you control your risk and position size every time you strike a deal in the foreign exchange market.

This calculator is also available as a downloadable MetaTrader expert advisor. The advantages of the MetaTrader version are:

  • Very fast calculation (once set up).
  • Easy-to-use drag-and-drop interface with a graphical panel.
  • Position size calculated in the same software that is used for trading.
  • Will work for you even when you are offline.
  • Calculate position size even if EarnForex.com is temporarily offline.
  • Trade based on your calculated position size.

The disadvantages of the MetaTrader version are:

  • Requires MetaTrader (4 or 5) installation.
  • Requires downloading and installing the expert advisor.
  • It is not as intuitive as this simple lot size calculator.

You might also find our pip value calculator useful. It can help you to find the value of the pip for various currency pairs and for the nonstandard account currencies.

Forex trading bears intrinsic risks of loss. You must understand that Forex trading, while potentially profitable, can make you lose your money. Never trade with the money that you cannot afford to lose! Trading with leverage can wipe your account even faster.

CFDs are leveraged products and as such loses may be more than the initial invested capital. Trading in CFDs carry a high level of risk thus may not be appropriate for all investors.
