Most traders focus on spreads. But if you hold positions overnight, swap fees can cost more than your spread — especially across a week. Here is exactly how they work.
Most beginner traders focus on spread costs — the difference between bid and ask price. But for anyone holding positions overnight, swap fees (also called rollover fees or overnight financing charges) are an often-overlooked cost that compounds daily.
This guide explains what swaps are, how EU-regulated brokers calculate them, when they can work in your favour, and how to compare swap rates across brokers before you choose one.
A swap (also called a rollover) is an interest adjustment applied to any forex position that remains open past the daily market close. In forex markets, the conventional close is 5pm New York time (EST/EDT). Any trade still open at that moment is "rolled over" to the next trading day, and a swap fee is applied.
Swaps exist because forex is traded on margin — you are borrowing one currency to buy another. The interest rate differential between the two currencies determines whether you pay or receive a swap:
Brokers calculate swaps using a formula based on the current interest rate differential, your position size (in lots), and the current exchange rate. The formula is approximately:
Swap (per night) = (Lot size × Contract size × Swap rate in pips) × Pip value
Assume: EUR/USD swap rate = −0.5 pips per night (negative = you pay)
1 standard lot = 100,000 units. EUR/USD pip value ≈ $10 per pip for a 1-lot position.
Nightly swap = 0.5 pips × $10 = $5.00 deducted per night
Over 5 nights (Mon–Fri): $25 total swap cost — before Wednesday's triple rollover.
On Wednesday night, the swap is 3× the daily rate: 0.5 pips × 3 = 1.5 pips = $15 on Wednesday alone.
This catches many beginners off guard. Forex transactions settle on a T+2 basis (two business days after the trade date). When a position is rolled over on Wednesday night, the settlement date jumps from Friday to Monday — spanning the weekend (three calendar days instead of one).
To compensate for the three days of financing across the weekend, brokers charge three times the normal daily swap on Wednesday night. This "triple swap" occurs every Wednesday without exception.
Swap rates are not fixed — they change when central bank rates change. The rates below were sourced from each broker's MT4/MT5 platform specifications in June 2026 and are for illustrative comparison only. Always verify current rates directly in the platform before trading.

Most EU-regulated brokers offer swap-free accounts — originally designed for Muslim traders for whom interest payments (riba) are prohibited under Islamic finance principles. These accounts are now widely available to any retail trader on request.
Instead of daily swap charges, brokers using swap-free accounts typically charge one of the following:
Whether a swap-free account is cheaper than a standard account depends entirely on how the broker structures its fees. For frequent short-term swing traders, swap-free accounts can reduce total costs. For longer-term position traders, the flat admin fee may exceed what the standard swap would have cost.
If you are a day trader or short-term intraday trader, closing all positions before 5pm EST avoids swap charges entirely. Most scalpers and day traders use this approach.
Carry traders deliberately choose positions where the long side of the pair carries a positive swap — earning overnight income on top of any price gains. Research the interest rate differential of your preferred pairs before trading.
If you must hold overnight but want to avoid the Wednesday triple swap, close any position before Tuesday's 5pm EST market close and reopen after Wednesday's close. This eliminates the 3× charge but reintroduces the spread cost of re-entering the trade — weigh the two costs for your position size.
If your strategy involves holding positions for multiple days or weeks, request a swap-free account. Calculate the broker's flat admin fee vs. the standard nightly swap for your typical position size — and choose whichever is cheaper.
For swing traders, the difference in swap rates between brokers can be significant over time. A −0.49 pip swap vs. a −0.72 pip swap on EUR/USD on a 1-lot position is a difference of $2.30 per night — $11.50 per week — $46 per month — $552 per year. On multiple positions, this adds up quickly.

A swap is an interest adjustment applied to any position held past the daily close (5pm New York time). It reflects the interest rate differential between the two currencies. If you hold a higher-rate currency, you may receive a positive swap. If you hold a lower-rate currency, you pay a negative swap.
Forex settles on T+2 (two business days). Rolling over on Wednesday means settlement skips the weekend — three days instead of one. Brokers apply 3× the daily rate on Wednesday nights to account for this. Wednesday is typically the most expensive night to hold a position.
Yes. Being long a currency with a higher interest rate than the currency you are selling generates a positive swap credit. This is the basis of carry trading. However, carry trades carry currency risk — price moves can outweigh overnight income.
An account that replaces swap charges with a flat admin fee per night (or no fee for short positions). Available from most EU-regulated brokers on request. Whether it is cheaper than a standard account depends on the broker's fee structure and your position holding period.
