### Position Size Calculator

EURUSD position size calculator is also called lot size calculator because position or lot is the same. Lot defines how many units of base currency you will use and position tells you how large the volume you will use.

When you use volume and number of units into the calculation it is the same variable we are talking about.

So when calculating the EURUSD lot size of a trade you are calculating EURUSD position size.

### How to Use Lot Size Calculator

In this example you can see that I have defined all variables inside lot size calculator:

- Instrument: EURUSD
- Deposit Currency: USD
- Stop Loss (pips): 200
- Account Balance: 10,000
- EURUSD 1 Pip Size: 0.0001
- Risk: 2%
- Contract size(Units per Lot): 100,000

These are variables that you need to define:

**Instrument**: EURUSD**Deposit Currency**: USD**Stop Loss**(pips): 200**Account Balance**: 10,000**Risk**: 2%

The EURUSD 1 pip size and contract size is already defined by the Forex instrument.

#### Calculate Lot Size for EURUSD

The Lot size calculator takes these values and first calculates the Lot size needed to be used in order to get risk to 2%.

**Risk = 2% out of $10,000 = $200**

**Stop Loss = 200 pips**

**Pip value = $10 per 1 lot**

**Stop Loss in $ = 200 pips x $10 = $2000 per 1 lot**

Now, we have a $2000 stop loss if we use 1 lot. But, in order to get to 200 which is 2% risk as I have defined I need to divide Stop Loss with 10. That means I need to use Lot size 10x less that it is used in calculations and that was 1 lot.

**Lot size = 1 lot = $10/pip -> 1 lot / 10 = 0.1 lot**

**Lot size = 0.1 lot = $1/pip**

**Stop Loss in $ = 200 pips x $1 = $200 per 0.1 lot**

This is how we have lot size calculated in this example.

#### Calculate Units (trade size)

When you have Lot size = 0.1 this is easily converted to the number of units.

**1 Lot = 100,000 units of base currency.**

**0.1 lot = 10,000**

And this is how we got the number of units for the 0.1 lot.

## Conclusion
