Does margin interest apply even if the trade is profitable?

Yes. Margin interest is a carrying cost charged by your broker for the borrowed funds, separate from whether the underlying trade wins or loses.

How this is calculated

Daily interest equals your annual rate divided by 365, multiplied by the amount borrowed. Total interest for the period equals that daily figure multiplied by the number of days held.
This uses simple daily interest and does not compound. Most brokers accrue margin interest close to this way, but confirm your broker's exact compounding and billing method, since some accrue daily and post monthly.
This cost applies whether the trade wins or loses. It's a fixed carrying cost of using borrowed money, on top of any price risk on the position itself.
Margin interest rates vary by broker and by how much you borrow, and can change without notice. Use your broker's actual current published rate, not a rate from another broker or one you remember from before.
