Overnight Swap Fees Explained 2026: How CFD Holding Costs Really Work
Most CFD traders focus on spreads and commissions but overlook a third cost: overnight swap fees. For swing traders holding positions 1–14 days, swap can quietly eat 5–15% of annual returns. For longer-term position traders, swap is often the single largest trading cost.
This 2026 guide explains exactly how swap fees work, when brokers charge them, how to calculate them for any currency pair or commodity, and—most importantly—how to reduce or eliminate them.
What Is an Overnight Swap Fee?
An overnight swap fee (also called a “rollover fee” or “overnight holding cost”) is the interest charged or credited for holding a leveraged position past the broker’s daily cut-off time (typically 5:00 PM New York time, or 21:00 UTC during US daylight saving).
It exists because when you trade a CFD, you don’t actually own the underlying asset—you have a contract with your broker. To make that contract realistic, the broker simulates the economic effect of holding the real asset, including interest-rate differentials. That’s what the swap represents.
For forex, the swap is the interest-rate differential between the two currencies in the pair. For commodities and indices, it’s typically based on the underlying interbank rate plus a broker markup.
How Swap Is Calculated: The Core Formula
The generic formula for swap on a CFD position is:
Swap = Position Size × Point Value × Swap Rate (in points)
But brokers quote swap in different ways. Here’s how the math works for the major CFD categories:
Forex Swap (Major Pairs)
For a forex pair, the swap is the tom-next interest rate differential between the two currencies, plus the broker’s spread markup.
Example: EUR/USD at 1.1000, 1 standard lot = $100,000 notional.
- USD interest rate: 4.50%
- EUR interest rate: 2.50%
- Theoretical swap: $100,000 × (4.50% – 2.50%) / 365 ≈ $5.48 per day (long position)
- Broker markup of 0.25% pushes it to about $5.20–$5.30 per day.
If you’re short EUR/USD, the swap is reversed in sign: you’d pay roughly $5.20/day or earn roughly $5.20/day, depending on the rate differential.
The per-lot-per-day figure varies widely. To check your specific broker’s swap rates, use the swap calculator or read the swap specification in your platform.
Commodity Swap
For commodities like gold (XAU/USD), the swap is based on the underlying funding rate for holding physical metal—essentially LIBOR/SOFR plus broker markup.
- XAU/USD: typically 0.01%–0.05% of position notional per day
- WTI Crude Oil: 0.02%–0.04% per day on long, often significantly higher on short positions due to storage and contango costs
Index and Stock Swap
For indices and individual stock CFDs, swaps are usually tied to the overnight interbank lending rate (SOFR for USD-denominated) plus a broker markup.
- US500 (S&P 500): typically 0.02%–0.04% per day
- AAPL stock CFD: ~0.03% per day on long, may be negative on short
Triple Swap Day: The Wednesday Effect
Wednesday is triple swap day for most CFD brokers. This is because spot forex settles T+2, so to roll a Wednesday position to Thursday, the broker effectively settles three days of interest (Saturday, Sunday, Wednesday).
The triple charge applies at:
- 5:00 PM New York time on Wednesday for most forex pairs
- 10:00 PM GMT on Wednesday for some platforms
- 22:00 UTC on Wednesday for uzfx and other modern platforms using UTC cut-off
If you hold a position through Wednesday close, you pay 3× the normal swap. Plan your holding period around this:
| Hold opened | Close before Wed 5pm | Hold through Wed |
|---|---|---|
| Monday | 1 day swap | 4 days swap |
| Tuesday | 0 days swap (overlap risk) | 3 days swap |
| Wednesday | full triple swap | — |
| Thursday | 0 days swap | 5 days swap |
| Friday | 0 days swap | 2 days swap (Sun/Mon) |
For low-cost swing traders, closing positions before the Wednesday triple swap saves real money.
When Are Swap-Free Accounts Available?
Some brokers (UZFX included) offer swap-free accounts for traders who can’t pay or receive swap due to religious or personal reasons. These accounts typically:
- Inherit the swap as a fixed administrative fee on overnight positions, OR
- Limit position holding periods to intraday only, OR
- Charge a wider spread to compensate for the absence of swap income/expense
If you trade on a swap-free account, the economic effect is similar—you pay a holding cost, but it’s transparent and predictable.
Reducing or Eliminating Swap Costs
1. Hold Intraday Only
If your strategy allows, close all positions before 5:00 PM New York. With intraday-only discipline, you pay zero swap fees regardless of the broker.
2. Trade Swap-Positive Pairs
Some pairs have positive swap on the long side, meaning the broker pays you to hold the position long. This is rare but exists with high-yielding currencies (MXN, ZAR, TRY) or in specific rate environments.
Check your broker’s swap schedule. If you’re long ZAR/JPY in a high-rate ZAR environment, you might actually earn swap while holding.
3. Use Limit Orders and Avoid Multi-Day Holds
If you don’t need to hold through Wednesday, don’t. Set your exit before the triple swap window.
4. Position-Size Around Swap Cost
Before opening a position, calculate the daily swap cost. If you can’t make 5–10× that cost in expected profit, the trade is too small or too long relative to swap drag.
Example: 0.1 lot EUR/USD position with $0.52/day swap, held 7 days = $3.64 swap. If your target is 30 pips ($30 profit), swap drag is ~12% of your edge.
5. Trade Commodities Strategically
Energy CFDs (WTI, Brent, Natural Gas) carry significant storage cost implicit in their swap rates, especially on the long side. Short energy positions often carry lower swap. If you have a directional bias on crude oil, going short rather than long can substantially reduce total holding cost.
Comparing Swap Across Brokers
Swap rates are not standardized across brokers. Each broker sets its own rate based on:
- Interbank funding rate (LIBOR/SOFR for USD pairs)
- Their own treasury cost of funds
- Markup for profit
Examples of daily swap on EUR/USD at 1 standard lot (long), 2026 rates:
| Broker | EUR/USD Long Swap | EUR/USD Short Swap |
|---|---|---|
| Major broker A | –$5.20 | +$2.40 |
| Major broker B | –$5.80 | +$1.95 |
| UZFX | published in contract specs | published in contract specs |
| ECN broker | –$4.10 | +$3.10 (low markup) |
UZFX publishes exact swap rates per instrument in its contract specifications and updates them weekly. Always verify the most recent swap values before placing a position.

The Hidden Cost: How Swap Compounds
Most traders underestimate swap because it’s charged daily. Let’s quantify the impact:
Scenario: Open 1 standard lot EUR/USD long at $5/day swap, hold for 30 days.
- Total swap cost: $5 × 30 = $150
- On a $10,000 account: 1.5% drag in one month
- Annualized (compounding): ~18% per year
That’s almost as much as typical trading edge. If your strategy wins 60% of the time but pays $150/month in swap, your net edge is much thinner than the win rate suggests.
For long-term traders holding 6–12 months, swap drag is often the reason their account grows slower than backtested returns.
Tools for Managing Swap
Free Calculators
Most CFD brokers, including UZFX, offer built-in swap calculators showing exact cost per instrument per lot size per day. The UZFX swap calculator lets you input your instrument, lot size, and holding period to see total holding cost.
Position Sizing Discipline
The simplest rule: don’t hold positions that pay you 1× swap to make 3× swap in profit. The swap-to-target ratio matters more than the absolute trade direction.
Swap vs Spread vs Commission: How They Compare
CFD traders often compare brokers only on spread. But total cost over many trades is:
Total Cost = Spread + Commission + Swap × Days Held + Slippage
For a swing trader holding 10 days, swap can easily exceed spread as the dominant cost. For a scalper holding 30 seconds, spread is everything. Match your broker evaluation to your strategy.
| Trader Style | Dominant Cost | Look Closely At |
|---|---|---|
| Scalper (seconds) | Spread | Tight spread, fast execution |
| Day trader (minutes/hours) | Spread + small swap | Spread + execution quality |
| Swing trader (1–14 days) | Swap + spread | Swap rates + spread |
| Position trader (weeks–months) | Swap | Swap rates, rolling cost |
Frequently Asked Questions
What is an overnight swap fee in cfd trading?
An overnight swap fee is the interest charge (or credit) for holding a leveraged CFD position past the broker’s daily cut-off time, typically 5:00 PM New York. It represents the interest-rate differential between the two currencies or the funding cost of the underlying asset.
When is swap charged on CFDs?
Swap is charged at 5:00 PM New York time (or 21:00 UTC during US daylight saving) for each day you hold a position overnight. On Wednesdays, the swap is triple-charged to compensate for the weekend settlement.
How is forex swap calculated?
Forex swap = Position Size × Swap Rate (in points). For a EUR/USD long at 1.1000 with 1 standard lot ($100,000 notional) and a 2% interest rate differential, daily swap is roughly $100,000 × 2% ÷ 365 ≈ $5.48 before broker markup.
Can I avoid paying swap fees?
Yes—if you close all positions before the swap cut-off time each day (intraday-only trading), you pay zero swap. Alternatively, use a swap-free account where holding cost is replaced by a fixed administrative fee.
Why is Wednesday triple swap?
Because spot forex settles T+2 (two business days), the broker needs to “pre-pay” weekend interest when rolling a Wednesday position. The triple charge covers Saturday, Sunday, and Wednesday interest in a single billing event.
Is swap the same as commission?
No. Commission is charged per trade by some brokers (typically $3.50/lot each side on ECN accounts). Swap is a daily holding cost on leveraged positions, separate from commission.
