What is the difference between nominal and real interest rates?

• A. The difference between interest before taxes.
• B. The interest rate not adjusted for inflation versus the rate adjusted for inflation.
• C. The guaranteed rate on government bonds.
• D. The rate charged for checking accounts.

Answer: (B)

Understanding nominal versus real interest rates means seeing how inflation changes money’s buying power. The nominal rate is the rate you’re quoted or earn in dollars, not adjusted for inflation. The real rate removes inflation to show the true growth in purchasing power. A practical way to think about it: if the nominal rate is 5% and inflation is 2%, the real rate is about 3%—your money’s actual buying power grows by roughly 3% each year. If inflation were 6% while the nominal rate stays at 5%, the real rate would be negative, meaning your purchasing power actually falls. This distinction is not about taxes, a guaranteed government bond return, or checking-account fees or rates. It centers on whether inflation is accounted for when measuring the return, which is exactly what the difference between the rate not adjusted for inflation and the rate adjusted for inflation captures.
