In plain English
What Overnight financing means
Because many CFDs are open-ended rather than settled immediately, providers commonly apply a daily funding adjustment when a position remains open after a stated time. Long and short positions can have different rates, and the calculation may vary by asset class, currency, and whether the CFD references a cash market or a futures contract. The provider should disclose the cutoff, annualized rate or formula, day-count convention, and any multi-day charge around weekends or holidays.
Why it matters
Financing can materially affect the net result of a position held for days or weeks, even if the underlying price barely changes. It is typically based on the full notional exposure rather than only the margin posted. Comparing the provider’s stated financing methodology and checking the actual daily booking helps explain holding costs and prevents margin from being mistaken for total exposure.
Example
Assume a long CFD position has $20,000 notional exposure and a simplified annual financing rate of 8%, using a 365-day basis. One day’s charge is approximately $20,000 × 0.08 ÷ 365 = $4.38. If held over a three-day weekend charge, the simplified cost is about $13.15. Actual provider formulas can differ.
Quick answers
Common questions
Is overnight financing charged on the margin amount?+
Commonly, it is calculated from the position’s notional value or full underlying consideration, not solely from the margin posted. The exact base and formula are set out in the provider’s product terms.
Why might an overnight charge cover more than one day?+
Providers may apply combined financing for days when the relevant market or settlement calendar is closed, often around weekends and holidays. The timing and multiplier should be disclosed in the contract specification.
