Interest Rate vs. Borrowing Rate - Difference I have never studied economics so the question might be very basic one and would need understandable answer: I would like to know the difference between Interest Rate term and Borrowing Rate term? As far as I understand the Borrowing Rate means when some company borrows money from the bank to pay for some internal staff needed to do their work (e.g. manufactury to buy some materials to produce their own products). Then company returns the money to the bank but with little additional fee and this additional fee is Borrowing Rate in % unit. Please confirm if this is correct. Even if it is, I still don't know the DIFFERENCE between Borrowing Rate and Interest Rate.
The Interest Rate is a more general term, and can cover all shorts of financial transactions where one expects by a contractual clause to get their money back plus "a little something" (I am not referring to the expected profit from an investment, where the "little something" is not a contractual obligation).

So you can talk about "the interest rate of a loan" but also of the "interest rate of a deposit in the bank".  

The Borrowing Rate specifically refers to the Interest Rate that the entity under consideration (a business, a public sector, or an individual) has to accept to pay as this extra little something if they want to borrow funds.

So the "borrowing rate" is an "interest rate" - one among many kinds of interest rates.
