If you hold a short-term trade and want to keep it open overnight, you’ll be charged a daily interest fee.
This charge will be applied to Daily Funded Bets (DFBs) as well as cash CFD positions held through 10pm (UK time).
Futures and forwards don’t incur overnight funding charges, but they do have wider spreads. These contracts are typically used for longer-term trades.
Why is overnight funding charged?
When placing a spread bet or CFD, you’re using leverage. This means you are effectively being lent the money required to open your position, outside the initial deposit you’ve paid. To keep your position open after 10pm (UK time), an interest adjustment will be made to your account to reflect the cost of funding your position overnight.
How can I see what I’ve been charged?
Overnight funding charges appear as separate transactions on your account and won’t affect your running profit/loss. A statement which contains all deals and associated charges is automatically sent to your registered email address at the end of each day.
How is overnight funding calculated for each market?
Indices
| Spread bet | CFD | |
For each day that a DFB or cash CFD position is open on a stock index, adjustments are calculated to reflect the effect of interest and dividends (if applicable).
Cost currency is determined by the DFB currency for spread bets and the currency of the underlying asset for CFDs.
Interest rate benchmark is calculated according to the currency of the underlying instrument. Please note that open positions held through 10pm (UK time) on Fridays will be adjusted for three days’ worth of funding to cover the weekend. |

Formula:
Bet size x price × (3%* admin fee +/- SONIA% ) ÷ 365 |
Formula:
Number of contracts x value per contract x price x (3%* admin fee +/- SONIA%) ÷ 365
* Mini contracts incur a 3% admin fee |
|
* Price = price at 10pm (UK time) + if long - if short
365-day divisor used for the FTSE 100 and other GBP, SGD and ZAR denominated markets. 360-day divisor used for all other markets. |
||
Example: You’re long £6 per point on the FTSE 100 The 10pm (UK time) price is 7720 The SONIA rate* is 0.48%
Cost = £6 x 7720 x (3% + 0.48%) ÷ 365 =£46,320 x 3,48% ÷ 365
= £4.41 overnight charge
* We use the SONIA and the 365-day divisor since you’re trading the UK Index in GBP |
Example: You’re short two contracts on the US Tech 100 The contract value is $100 The 10pm (UK time) price is 6957 The SOFR rate* is 1.53%
Cost = 2 x $100 x 6957 x (3% - 1.53%) ÷ 360 = $1,391,400 x 1.47% ÷ 360
= $56.79 overnight charge
* We use the SOFR rate and the 360-day divisor since you’re trading the US Index in USD |

Cost currency is determined by the DFB currency for spread bets and the currency of the underlying asset for CFDs.
Interest rate benchmark is calculated according to the currency of the underlying instrument.
Borrow charge: When you are shorting a stock via a DFB spread bet or cash CFD, you will incur a borrow charge. The borrow charge will be accounted for in a daily cash adjustment applied to your account. The charge varies according to the stock, is notified to us by our brokers or agents and includes a 0.5% administration fee. The borrow charge, and the ability to hold a short position, can be changed at short notice. To determine whether a borrow charge applies and if so, what the charge is, call our dealers in advance of betting/trading.
Please note that open positions held through 10pm (UK time) on Fridays will be adjusted for three days’ worth of funding to cover the weekend. |

Formula:
Bet size x price × (3%* admin fee +/- relevant interest rate benchmark%) ÷ 365 |
Formula:
Number of contracts x value per contract x price x (3%* admin fee +/- relevant interest rate benchmark%) ÷ 365
* Mini contracts charged 3% admin fee |
|
* Price = price at 10pm (UK time) + if long - if short
365-day divisor used for the FTSE 100 and other GBP, SGD and ZAR denominated markets. 360-day divisor used for all other markets. |

Example: You’re short £12 per point on Adidas AG (German stock) The closing price is 18915 The ESTR rate is -0.37% As you are short there is a Borrow Premium 0.5%
Cost = £12 x 18915 x (3% - (-0.37%)) ÷ 360 = £226,980 x 3.37% ÷ 360 = £21.24 funding charge
Borrow premium = 18915 x 12 x 0.5% ÷ 360 =£3.15
Total charge = £21.24 + £3.15
= £24.39 overnight charge |
Example: You’re long 1500 contracts on Rio Tinto Ltd (Australian stock) The contract value is AUD 1 The closing price is 83.90 The 1-month AUD LIBOR rate is 1.89%
Cost = 1500 x 1 x 83.90 x (3% + 1.89%) ÷ 360
= £125,850 x 4.39%/ 365
= AUD 16.86 overnight charge |

For forex and spot metals deals, we charge the tom-next rate plus an admin fee of 0.8%.
What is the tom-next rate? Find out more here. Please note that forex positions held through Wednesday 10pm (UK time) will incur three days’ worth of funding to cover the settlement of trades over the weekend. This is because FX settles on a T+2 basis. Therefore, when a position is held through Wednesday 10pm (UK time) it's effectively being held through the weekend as positions can't be settled until after Friday 10pm (UK time). Subsequently, holding through Friday will only incur one day's worth of funding. |

The easiest way to work out overnight funding costs on FX pairs is to look up the swap rate on our platform (click here to find out how to do this) and to use the formulas below:
|
||
Formula: Long: Bet size x offer swap rate
Short: Bet size x bid swap rate
Example: You’re short £3 per point on GBP/USD The GBP/USD swap bid is 0.22 £3 x 0.22 = £0.66 credit |
Formula: Long: Number of contracts x value of contract x offer swap rate
Short: Number of contracts x value of contract x bid swap rate
Example: You’re long one EUR/USD $10 contract The GBP/USD swap offer is -0.85
1 x $10 x -0.85 = $8.50 debit |
|
| What is the base calculation for FX funding? | ||
Formula: There are three steps to this formula:
1. Value Price in points x 1% ÷ 360
2. Swap rate When going short: Tom-next rate – value
When going long: Tom-next rate + value
3. Cost Bet size x swap rate |
Formula: There are three steps to this formula:
1. Value Price in points x 0.3% (1% for mini contracts) ÷ 360
2. Swap rate When going short: Tom-next rate – value
When going long: Tom-next rate + value
3. Cost Number of contracts x value of contract x swap rate |
|
Example: You’re long £3 per point on EUR/USD The tom-next rate is 0.34 bid/0.39 offer The closing spot price is 1.0650
Value = 10650 x 1% ÷ 360 = 0.29583 Swap rate = 0.39 + 0.29583 = 0.69 (rounded)
Cost = 3 x 0.69 = £2.07 debit*
* This is a debit since the offer interest rate is higher than the bid rate and you are holding a long position. |
Example: You’re short one EUR/USD standard lot The contract value is $10 The tom-next rate is 0.34 bid/0.39 offer The closing spot price is 1.0650
Value = 10650 x 1% ÷ 360 = 0.29583 Swap rate = 0.34 – 0.29583 = 0.04 (rounded)
Cost = 1 x $10 x 0.04 = $0.40 credit* * This is a credit since the bid interest rate is lower than the offer rate and you are holding a short position. |

Commodities
Prices for commodity DFBs and cash CFDs are synthetically created using the two most liquid futures contracts. This will result in a natural movement between these two contract prices and will be included in overnight funding adjustments. You’ll then either be debited or credited depending if you’re long or short, and whether the next future contract price is higher or lower.
To find out more on how we price our commodities, please click here.
Commodity funding is based on the market cost of carry, plus an admin fee of 3% per annum. Please note that open positions held through 10pm (UK time) on Fridays will be adjusted for three days’ worth of funding to cover the weekend. |

Formula: There are three steps to this formula:
1. Basis (the daily movement along the futures curve) (P3 – P2) ÷ (T2 – T1)
T1 = expiry date of the previous front future T2 = expiry date of the front future P2 = price of front future P3 = price of next future
2. IG charge Price x 3% ÷ 360
3. Adjustment Bet size x (basis + IG charge) |
Formula: There are three steps to this formula:
1. Basis (the daily movement along the futures curve) (P3 – P2) ÷ (T2 – T1)
T1 = expiry date of the previous front future T2 = expiry date of the front future P2 = price of front future P3 = price of next future
2. IG charge Price x 3% ÷ 360
3. Adjustment Bet size x (basis + IG charge) |
|
Example: You’re long £10 per point on Oil – US Crude T2 – T1 = 31 days P2 price is 4700 P3 price is 4770
Basis = (4770 – 4700) ÷ 31 = £2.258 IG charge = 4700 x 3% ÷ 365 = £0.386
Adjustment = £10 x (£2.258 + £0.386) = £26.44* * The £26.44 basis adjustment would be offset in the running profit or loss on this position. |
Example: You’re short one $10 contract on Oil – US Crude T2 – T1 = 31 days P2 price is 4700 P3 price is 4770 Basis = (4770 – 4700) ÷ 31 = £2.258 IG charge = 4700 x 4% ÷ 365 = £0.386
Adjustment = £10 x (£2.258 - £0.386) = £18.72* * £18.72 will be credited to your account as you were short, and the next future contract was higher than the front contract. |

Formula:
Long position: Bet size x price x (IG fee + overnight funding rate)
Short position: Bet size x price x (IG fee - overnight funding rate) |
Formula:
Long position: Number of contracts x value per contract x price x (IG fee + overnight funding rate)
Short position: Number of contracts x value per contract x price x (IG fee - overnight funding rate) |
|
Example: You are long £1 per point on bitcoin The current price is 3500
Cost = (£1 x 3500) x (0.0277% + 0.0417%) =£3500 x 0.0694%
= £2.43 cost |
Example: You are short 20 lots of litecoin The contract value is $1 The current price is 31.26
Cost = (20 x $1 x 31.26) x (0.0208% – 0.0556%) = $625.20 x -0.0348% = $21.75 debit |
