How is Margin Funding interest calculated on Bitfinex
The interest on Margin Funding is calculated based on the amount, rate, and period that funding has been provided/taken.
Note: Funding takers and providers will pay or receive funding interests in the same currency the funding is offered.
For funding takers
Margin funding interest to pay is calculated as follows:
Important: If you reserve and return funds manually within an hour, you will pay a full hour's interest regardless of whether the funding has been used in a financed position. For details, please view our Fees page.
For funding providers
Margin funding interest earnings is calculated in such a way:
As a funding provider, you will receive the interest paid by the user taking your funding, with a 15% fee deducted.
Note: A 18% fee is charged when funding is opened with a hidden offer. Also note that funding interests below the minimum lot size (0.00000001) will not be credited to your account.
For example: If you have an active $10,000 offer at 0.06%, you will earn $6.00 per day. On the $6.00 earnings, a 15% fee is charged, which would be a $0.90 fee. You will receive $5.10 per day during the time the funding offer is taken.
Important: Bitfinex will charge a minimum of one full hour's interest to the borrower on any funding that is borrowed and manually returned. As a funding provider, you will receive the full hour earnings minus a 15% fee.
