Camille, we usually refer to an interest rate (r in the compounding and discounting equations) as a discount rate when we are using the discounting formula -- taking the net present value. When we are using an interest rate to discount, the rate represents the "required" return for us to consider investing in a proposed investment. When we talk about "normal" interest rates, such as what you would earn on an investment, it is the interest rate we expect to earn.
