Overnight Interest

Forex Swap Calculator

Calculate the interest you will earn or pay for holding positions overnight. Perfect for swing traders and long-term investors using carry trade strategies.

What is Swap?

Forex swap, or rollover interest, is the net interest return on a currency position held overnight. When you trade currencies, you are borrowing one to buy another.

If the interest rate of the currency you bought is higher than the one you sold, you earn interest (Positive Swap). If it is lower, you pay interest (Negative Swap).

The Triple Swap Rule

Because the Forex market is closed on Saturdays and Sundays, brokers usually charge or pay three days worth of swap on Wednesday nights to account for the weekend rollover. Always check your broker's specific schedule!
