Getting exchange rates…
Swap changes by broker and by day. Many brokers charge three days of swap on one weekday (often Wednesday) and none on weekends, so the days you hold are not simply the calendar days. Look up the current swap points on your trading platform and type them in; this page does not fill them in.
Swap = points x point size x contract size x lots, where 1 point is a tenth of a pip (: 1 pip = ). Some brokers show swap in money or in percent instead of points; this page takes points only.

These are estimates for working out a trade. They leave out spread, commission, slippage and swap unless a field says otherwise, and every broker rounds lots and calculates margin in its own way. Check the figures on your trading platform. Nothing here is investment advice.

What this calculator tells you
This calculator adds up the swap, the interest-like amount charged or paid when a position is held past the daily rollover. You type in the swap points your broker shows and the number of days, and it gives the amount per day and in total. A minus sign means a cost.
Worked examples
EURUSD, 1 lot, -6.5 points per day: -6.5 USD a day, and -195 USD over 30 days.
The same points at 0.5 lot for 10 days come to -32.5 USD. The amount scales with the lot size.
Common mistakes and things to check
- Swap points change by broker and by day, and long and short differ. Read the current figure on your platform; this page does not fill it in.
- Many brokers charge three days of swap on one weekday and none on weekends, so the days charged are not the calendar days.
- Some brokers show swap in money or percent instead of points. This page takes points only.
- A plus sign can turn into a cost when rates change. Do not assume a positive swap will last.
- Swap is only one part of the cost of holding. Spread and commission are separate, and none of them are included here.
