How to calculate pips
In most cases, a pip represents a movement at the fourth decimal place. This is true of many of the most frequently traded currencies in the forex market. For instance, if the Australian dollar moves up in value by 0.0001, this is a growth of 1 pip. This is also the case of the US dollar.
In other cases, however, it's different. A pip will be at the second decimal place for currencies available in very small dominations. So, a movement of 0.01 on the Japanese yen - typically much smaller in value than one Australian dollar - would equal one pip.
Outside the forex market, pips may be represented differently. A pip in a precious metal commodity like gold will be at the third decimal place (0.001), while crypto pips tend to be at the first decimal place (0.1).
Here's an example:
Let's say you want to make a 10,000 euros trade against a EUR/USD currency pair, which features a fixed pip of 0.0001 - 10,000 multiplied by 0.001 is 1, which means the pip value is $1. If you bought 10,000 euros against the US dollar at 1.810 and sold at 1.820, you would receive a profit of 10 pips or $10.
