About this calculator
Nominal interest rate
The nominal rate is the stated rate before adjusting for inflation — the rate you see on deposits, loans, and bonds. It does not account for loss of purchasing power.
If you need a specific real (inflation-adjusted) return, this calculator finds the nominal rate required given an expected inflation rate.
Nominal = (1 + Real) × (1 + Inflation) − 1
