Real and Nominal Interest




Real Interest= Nominal Interest -  Expected Inflation \boxed{\text{Real\ Interest} =\text {\ Nominal\ Interest\ - \text\ Expected\ Inflation }}



  • Real interest looks at how much lenders really earn once we take inflation into consideration.
  • If expected inflation increases, real interest rate will
    decrease
    , which is
    bad
    for lenders and
    good
    for borrowers.
