How it is calculated

  1. annual rate = benchmark rate + broker spreadUse a benchmark of 0 if your broker quotes one all-in rate.
  2. daily interest = loan × annual rate ÷ day-count basisThe day-count basis is 360 or 365 days, as set by the broker.
  3. interest for the period = daily interest × days borrowedRates change with the benchmark, so check your broker's current schedule.

Illustrative estimates, not investment advice. Check your broker's own contract specifications, rates and fees before you trade. CFDs and leveraged products carry a high risk of losing money.
