Margin financing calculator
Enter a loan amount and the current benchmark level to see the applied annual rate, the daily accrual and the cost over any period.
Adjust the benchmark to reflect the current market level.

Interest is calculated by adding the tier spread to the benchmark rate, dividing the resulting annual rate by 360 and multiplying by the number of days. Figures are illustrative only.
How the calculation works
The applied annual rate is the benchmark for your loan currency plus the tier spread for your balance. That rate is divided by 360 to give a daily factor, which is applied to the balance outstanding each day.
Daily interest = Balance × (Benchmark + Spread) ÷ 360Because accrual is daily, borrowing for part of a month costs only that part. Because settlement is monthly, the accrued amount is charged once, in arrears.
Tier boundaries
The spread applied depends on the balance. Crossing into a higher tier reduces the spread on the whole balance, not merely the incremental amount — which is why a larger balance can carry a lower total rate.
What the calculator does not include
- Movements in the benchmark over the period — the figure shown assumes a constant benchmark
- Third-party costs such as exchange or custody fees
- Applicable taxes, which depend on your jurisdiction
- Any change in your tier resulting from a change in balance during the period
