    A basis point (often abbreviated as bp, often pronounced as "bip" or "beep" [ 1]) is one hundredth of 1 percentage point. Changes of interest rates are often stated in basis points. For example, if an existing interest rate of 10 percent is increased by 1 basis point, the new interest rate would be 10.01 percent. [ 2]
