Stock CFD costs explained

A stock CFD has three main costs, and the one that catches people out is the overnight fee. Here is exactly what you pay to trade and hold a share CFD, and how to keep it down.

6 min read Last updated · {{ today }}

The headline cost of a stock CFD is easy to see, but it is rarely the whole bill. Between the spread, any commission and the daily financing fee, the true cost depends as much on how long you hold as on what you trade. Get the three components straight and you can work out what any trade really costs before you place it.

The costs at a glance

CostWhat it isWhen you pay
SpreadThe gap between the buy and sell priceBuilt into every trade
CommissionA flat or percentage fee, on some account typesOn opening and closing
Overnight feeFinancing on the leveraged positionEach night you hold it
Dividend adjustmentAn adjustment over the ex-dividend dateIf held across ex-dividend
Currency conversionMarkup if the stock is in another currencyOn profit, loss or funding

The spread

The spread is the difference between the price you can buy at and the price you can sell at. You pay it the moment you open, because you start marginally in the red and need the price to cover the spread before you profit. Liquid, popular shares have tighter spreads; smaller or less traded ones are wider.

Commission

Some account types drop the spread markup in favour of a separate commission, a flat fee or small percentage charged on opening and closing. Neither model is automatically cheaper. A commission account can win for large or frequent trades, while a spread-only account is simpler for smaller ones. It pays to compare the two for how you actually trade.

The overnight fee, the one people miss

Because a CFD is leveraged, holding one is like borrowing to hold the full position, so the broker charges a small financing fee for every night it stays open past the daily cut-off. On a day trade this is negligible. Hold for weeks and it compounds quietly in the background, which is why CFDs suit shorter holds and owning the share can be cheaper long term.

Quick example
Open a share CFD and close it the same day, and you mainly pay the spread and any commission. Hold that same position for a month, and the nightly financing fee can quietly become the largest cost of the trade. Same share, very different bill.

How to keep costs down

  • Trade tight-spread shares with a broker known for competitive pricing.
  • Do not hold longer than you need to, so overnight financing does not build up.
  • Match your account currency to the stock’s currency to avoid conversion markups.
  • Compare account types, since a commission account can beat a spread-only one for your size.
