Overnight Fee
An overnight fee is the interest amount a broker credits or debits to a trader's account for holding a leveraged position open past the daily rollover time (typically 5:00 PM New York time).
Quick Definition Box
The overnight fee, also called a swap or rollover fee, is the cost of keeping a CFD or forex position open overnight. It reflects the interest rate differential between the two currencies in a pair, plus a broker markup. If you hold a position through Wednesday night, the fee is usually tripled to account for the weekend settlement.
Detailed Explanation
The overnight fee exists because leveraged trading involves borrowing capital. When you open a CFD or forex position with margin, your broker effectively lends you the notional value of the trade. That borrowed money has a financing cost, just like a bank loan. The overnight fee is how that cost is passed to you.
For forex pairs, the fee is derived from the difference between the interest rates of the two currencies involved. If you buy a currency with a higher interest rate than the one you sell, you may receive a positive swap (credit). If you buy the lower-yielding currency, you pay a negative swap (debit). This is not a fixed number — it changes daily based on central bank rates and market liquidity.
For CFDs on indices, commodities, or shares, the overnight fee is typically calculated as a benchmark rate (like SOFR or EURIBOR) plus a broker markup (often 1.5% to 3% annually). The formula usually looks like this:
Overnight Fee = (Notional Position Size × (Benchmark Rate + Broker Markup)) / 365
The notional position size is your trade's total value, not just the margin you put up. For example, a $10,000 position with 1:10 leverage requires only $1,000 margin, but the fee is calculated on the full $10,000.
The rollover time is standardized across most brokers at 5:00 PM New York time. If you hold a position at that exact moment, the fee is applied. If you open and close before that time, you pay no overnight fee. However, there is a special rule for Wednesday: because forex settles in two business days, holding through Wednesday night incurs a triple fee (covering Thursday, Friday, and the weekend). For some instruments, the triple swap day falls on Friday instead.
Real-World Example
Let's say you hold a long position of 1 standard lot (100,000 units) in EUR/USD. The current EUR interest rate is 3.5%, and the USD rate is 5.0%. The broker's markup is 0.5% annually.
- You are buying EUR (earning 3.5%) and selling USD (paying 5.0%).
- The raw differential is 3.5% − 5.0% = −1.5% per year.
- Add the broker markup: −1.5% − 0.5% = −2.0% per year.
- Daily fee = (100,000 × −2.0%) / 365 = −$5.48 per night.
If you hold this position for 10 nights, you pay $54.80 in total overnight fees. If you hold it through Wednesday night, that single night costs −$16.44 (triple). Now reverse the scenario: if you short EUR/USD (selling EUR, buying USD), you would earn approximately +$5.48 per night before any adjustments.
For a CFD on gold (XAU/USD), the calculation is different. Suppose gold is trading at $2,000 per ounce, and you buy 10 ounces (position size $20,000). The broker uses SOFR at 5.3% plus a 2% markup. Daily fee = ($20,000 × 7.3%) / 365 = $4.00 per night.
Why It Matters for Traders
Overnight fees directly affect the profitability of medium- and long-term trades. A position that looks profitable on price movement alone can become a net loser if held too long against a high negative swap. Conversely, positive swap can add a small income stream to a trade that is otherwise flat.
Day traders who close all positions before rollover are unaffected. Swing traders and position traders must factor the fee into their risk-reward calculations. For example, a trade targeting a 1% price move over two weeks might be wiped out by cumulative overnight fees if the swap is heavily negative.
The triple swap on Wednesday is particularly important. If you plan to hold a position for several days, the day you enter matters. Entering on Tuesday means you'll face the triple charge on Wednesday night. Entering on Thursday means you'll face it on Friday night (for some instruments). This can add or subtract a meaningful amount from your expected return.
Common Misconceptions
Misconception 1: "Overnight fees are only charged on losing trades."
False. The fee is applied regardless of whether your position is in profit or loss. It is purely a financing cost based on position size and interest rates.
Misconception 2: "You can avoid overnight fees by closing before 5 PM and reopening after."
Technically true, but you'll pay the spread twice (once to close, once to reopen). The spread cost often exceeds the overnight fee, making this strategy counterproductive unless the swap is extremely high.
Misconception 3: "Positive swap means you always make money holding overnight."
Not exactly. The swap is credited, but your position is still subject to market risk. A positive swap of $2 per night cannot offset a $200 adverse price move. Also, brokers can adjust swap rates at any time based on market conditions.

How XM Compares
XM provides transparent swap rates for all instruments on its website, updated daily. The rates are shown as both long and short swap values in points or monetary terms, depending on the platform. XM applies the standard 5:00 PM New York rollover time and uses the triple swap rule on Wednesday for forex pairs. For some CFDs, the triple swap day may differ — always check the instrument specification page. XM does not charge a separate commission on standard accounts, but the overnight fee includes a markup over the benchmark rate. As with all brokers, swap rates are subject to change without prior notice based on central bank decisions and market volatility. For the most current rates, refer to the official XM website or the MetaTrader platform's specification window.
