# How to calculate rollover in forex?

Forex trading is a popular investment option for many traders around the world. It provides a platform for investors to trade currencies, which in turn allows them to make a profit. When trading forex, it’s important to keep in mind the concept of rollover. This is the interest paid or earned on a position that is held overnight.

### What is Rollover?

Rollover is the interest paid or earned on a forex position that is held overnight. This is due to the difference in interest rates between the two currencies in the pair. Forex trading is done in pairs, and each pair has its own interest rate. If the interest rate on the currency you’re buying is higher than the interest rate on the currency you’re selling, you will earn interest on the position. If the opposite is true, you will pay interest on the position.

### How to Calculate Rollover?

Calculating rollover is relatively simple. It involves three things: the size of the position, the interest rate differential, and the length of time the position is held. The formula for calculating rollover is:

### Let’s break down each of these components:

Position Size: The size of the position is the amount of currency you’re buying or selling. This is measured in lots. One lot is equal to 100,000 units of the base currency.

Interest Rate Differential: The interest rate differential is the difference between the interest rate of the currency you’re buying and the interest rate of the currency you’re selling. This can be found on most forex trading platforms.

Time Held: The length of time the position is held is measured in days. This is important because rollover is calculated on a daily basis. If you hold a position overnight, you will be charged or paid rollover for that day.

365: This number represents the number of days in a year. It is used to calculate the daily rollover rate.

### Let’s look at an example:

Suppose you buy 1 lot of EUR/USD at a price of 1.2000. The interest rate on the euro is 0.25%, and the interest rate on the US dollar is 2.00%. You hold the position for 3 days. Using the formula above, we can calculate the rollover:

### There are a few things to keep in mind when calculating rollover:

1. Weekends: Rollover is not calculated on weekends. If you hold a position over the weekend, you will be charged or paid rollover for three days instead of two.

2. Holidays: Rollover is also not calculated on holidays. If a holiday falls on a weekday, you will not be charged or paid rollover for that day.

3. Interest Rate Changes: Interest rates can change at any time, which can affect the rollover rate. It’s important to keep an eye on interest rate changes and adjust your calculations accordingly.

### Conclusion

Rollover is an important concept to understand when trading forex. It can affect your profits and losses, so it’s important to calculate it correctly. By using the formula above and keeping in mind the things to keep in mind, you can calculate rollover accurately and make informed trading decisions.
