Managing overnight funding costs for stock CFDs

A stock CFD gives you leveraged exposure to a share's price without ownership of the underlying stock. If you keep the position open overnight, time can add a recurring cost or credit to the trade.

Bybit calls this adjustment a swap fee. You may also see it described as an overnight fee or rollover fee. Understanding the term, calculation and timing helps you compare a short-term opportunity with the cost of keeping it open.

Key takeaways:

• Bybit applies swap fees daily when a CFD position remains open past 00:00 server time.

• US Stock CFD swap fees use the position quantity, share price and contract's long or short swap rate.

• Check the live contract specification because swap rates and any three-day adjustment can vary by contract.

What are overnight swap fees on stock CFDs?

A contract for difference, or CFD, settles the price difference between the opening and closing levels of a referenced asset. You can take a long or short position without owning the underlying shares.

Each Bybit CFD contract has a swap fee. The fee accumulates daily based on how long you hold the position. It applies when the position remains open past 00:00 server time.

A negative swap rate creates a deduction from your account. A positive swap rate creates a credit. Bybit provides separate rates for long and short positions, so never assume both directions have the same overnight cost.

The charge affects your Account Equity as soon as it is applied. It appears in your Account Balance after the position closes.

How does Bybit calculate a US Stock CFD swap fee?

Bybit calculates US Stock CFD swap fees by percentage:

Swap fee = CFD quantity × share price × swap rate% ÷ 360

Use the contract's current swap rate for the direction of your position. The live Contract Info page contains the long rate and short rate.

How does the formula work in practice?

Bybit's Help Center gives an example using a long AAPL CFD position:

• CFD quantity: 10

• Share price: 198.36

• Long swap rate: -6.88%

The calculation is:

10 × 198.36 × -6.88% ÷ 360 = -0.379088 USDx

After rounding, the overnight swap fee is a deduction of 0.38 USDx. This example explains the method only. Prices and swap rates change, so use the live values shown for your contract before trading.

Why does position size matter more than deposited margin?

The formula uses your CFD quantity and the share price. It does not calculate the fee from the margin you posted.

Leverage lets a smaller margin balance control a larger position. This means an overnight fee may look small compared with the total exposure but feel much larger when compared with the cash supporting the trade.

Review the full position value when estimating swap fees. Then compare the result with your available margin and planned holding period.

When does Bybit apply the swap fee?

Bybit applies the fee when a position remains open past 00:00 server time. The MT5 client terminal normally uses UTC+3 and changes to UTC+2 after daylight saving time.

Check the time shown in your platform before relying on a conversion to your local time. A daylight saving change can move the local cutoff by one hour.

How does the three-day swap work?

A three-day swap may apply to account for weekend financing. On the specified day, the normal swap is multiplied by three to cover the weekend period.

The Help Center says this is usually applied on Wednesday, but the applicable day can depend on the contract. Check the contract specification instead of assuming the same schedule for every US Stock CFD.

Which costs should you include in a stock CFD trade?

Swap fees are only one part of the total trading cost. Review these items before opening a position:

• Spread: The difference between the bid price and ask price.

• Commission: In Tight-Spread Mode, US Stock CFDs have a separate commission. In Zero-Fee Mode, the commission is incorporated into the trade.

• Swap fee: The daily overnight adjustment based on the current contract rate.

• Slippage: The difference between the expected execution price and actual execution price.

The account mode changes how commission is presented. Review the selected mode and available balance because commission is charged from the MT5 CFD account balance.

For the product workflow and current interface, see the Bybit CFD trading guide.

How can you estimate the cost before holding overnight?

1. Open the Contract Info page. Record the current long or short swap rate for the selected US Stock CFD.

2. Confirm the server cutoff. Check whether your planned exit falls before or after 00:00 server time.

3. Apply the documented formula. Multiply CFD quantity by the current share price and swap rate, then divide by 360.

4. Count chargeable nights. Include any applicable three-day swap in the estimate.

5. Add the other costs. Include the spread, applicable commission and a realistic slippage allowance.

6. Compare cost with opportunity. Decide whether the expected price move justifies the total risk and cost.

How should your holding period shape the plan?

Intraday positions

A position closed before 00:00 server time does not cross the overnight cutoff. You still need to account for the spread, applicable commission and slippage.

Multi-day positions

Estimate the swap fee for every expected night and include the possible three-day charge. Recalculate if the trade lasts longer than planned or the live swap rate changes.

Event-driven positions

Earnings, company announcements and market holidays can create sharp moves or gaps. Include the overnight cost in the plan but give price risk more weight than a small fee difference.

How can you manage overnight swap fees?

1. Check both directional rates. Long and short swap rates are contract-specific and may produce different charges or credits.

2. Set a maximum holding period. Estimate a planned exit and a delayed exit before opening the trade.

3. Track server time. Recheck the cutoff when daylight saving time changes.

4. Plan for the three-day swap. Identify the applicable day from the contract specification.

5. Reassess the trade daily. Compare the remaining opportunity with the next swap fee and current market risk.

6. Keep sufficient balance. Leave room for commission, swap fees and adverse price movement.

What risks matter beyond the swap fee?

• Leverage risk: A relatively small market move can create a large loss or lead to liquidation.

• Gap risk: The market can move past a planned exit after earnings or unexpected news.

• Liquidity risk: A wider spread or limited depth can increase execution cost.

• Timing risk: Holding past the server cutoff can trigger a swap fee you did not include.

• Rate risk: The contract's live swap rate can change.

• Product risk: A CFD provides price exposure but no ownership rights in the underlying share.

Position size should reflect the potential market loss as well as the expected fees. A low swap fee does not make a leveraged position low risk.

How do you check swap fees on Bybit?

Before placing a US Stock CFD order, open the contract's Info page. Confirm the current long and short swap rates, contract size, margin requirement and trading schedule.

After the charge is applied, it affects Account Equity immediately. You can review it in Account Balance after closing the position.

If you extend the holding period, repeat the calculation with the current share price and swap rate. Current platform data takes precedence over educational examples.

The bottom line

Bybit uses the term swap fee for the overnight adjustment on a stock CFD. For US Stock CFDs, the calculation uses CFD quantity, share price and the contract's swap rate divided by 360.

Check the live contract specification, server cutoff and three-day swap rule before holding a position overnight. Add the result to the spread, applicable commission and expected execution cost so the full holding plan is clear before entry.
