What is the Swap Rate Calculator?
The Swap Rate Calculator estimates the overnight financing cost (or credit) for holding a forex position through daily rollover. Swap reflects the interest rate differential between the two currencies in the pair and the broker’s funding spread. For multi-day trades, swap can quietly consume a meaningful chunk of an otherwise profitable position.
How to use it
- Select the currency pair.
- Choose the direction: long or short.
- Enter the lot size.
- Enter the number of nights you plan to hold.
- Read the total swap cost (or credit, if positive) in your account currency.
Worked example
You go long 1 lot EUR/USD and plan to hold for 3 nights. The broker’s long swap on EUR/USD is −1.20 pips per night.
- Per night: −1.20 pips × $10 = −$12
- 3 nights: −$12 × 3 = −$36
Swap is debited at the rollover time defined by the broker, usually around server midnight.
Frequently asked questions
Why is Wednesday's swap triple?
Most brokers settle currency trades on T+2. To account for Saturday and Sunday when banks are closed, they charge or credit three days of swap on Wednesday night so that positions held into the weekend reflect actual interest carry.
Are swap-free accounts really free?
Islamic (swap-free) accounts replace the daily swap with other fees: a fixed administration fee per lot per night after a grace period, a wider spread, or a higher commission. Always read the swap-free schedule before assuming overnight costs are zero.
Why does my broker show a different swap to the default rates here?
The default rates shown are based on IC Markets Standard; every broker quotes its own swap. For an exact figure, enter your broker's posted long/short swap in the calculator inputs.
Do positions opened just before midnight pay swap?
Most brokers apply swap to positions that are open at the rollover snapshot. So even a position opened a few seconds before midnight server time can be charged a full night's swap. Plan entries around rollover when you want to avoid this.
