Swap calculator
What does holding this trade overnight cost?
Swap is charged or credited at every weeknight rollover a position stays open, and three times on Wednesday. For swing and position traders it quietly becomes the largest cost of the trade. Enter the swap from your platform and the planned hold.

Reading the number honestly
- Swap rates change daily with interest-rate differentials and the broker's mark-up. Take today's figure from the specification, not from memory.
- Wednesday rollover books Saturday and Sunday too — three nights at once. Five weeknight rollovers with one Wednesday is seven nights of swap.
- Positive swap is real but small, and brokers mark both sides against you: the long and the short rate on a pair rarely sum to zero.
- Swap-free accounts replace swap with a fixed admin fee after a grace period. Compare them on your holding period, not on the headline.
Questions
Why is swap negative on both long and short?
Swap reflects the interest-rate difference between the two currencies, plus the broker's mark-up. When the rate difference is small, the mark-up dominates and both directions cost money. That mark-up is part of the broker's revenue, like the spread.
What is triple swap?
Spot FX settles two business days ahead. A position held over Wednesday night settles on Monday, so Saturday and Sunday are charged on Wednesday — three nights of swap in one rollover. Some brokers triple on Friday for CFDs; check the specification.
How do I convert swap points to money?
Points × point size × contract size, converted to your account currency. On a 5-digit EUR/USD quote one point is 0.00001, so −8 points on a standard lot is −$8 per night. Choose “points” above, check the point size matches your platform's last decimal, and the calculator does the conversion.
