How Constant-Rate Salary Inflation Calculator Works?
The Constant-Rate Salary Inflation Calculator uses one assumed inflation rate for all years. It compounds that rate over the chosen time span.
Enter the salary
Type the current salary amount.
Pick one rate
Enter a single annual rate, such as the 2% Federal Reserve target or a 3% long-run average.
Choose the years
Set the time span from 1 to 40 years.

The calculator shows the inflation-matched salary and the shrinking real value of a frozen salary for each year.
Constant-Rate Salary Inflation Calculator Formula
The Constant-Rate Salary Inflation formula multiplies the salary by one plus the rate raised to the number of years.
Salaryt = Salary0 × (1 + r)t
Realt = Salary0 ÷ (1 + r)t
Variables
- Salary0
- Starting salary
- r
- Fixed annual inflation rate
- t
- Years elapsed
Worked example
A $72,000 salary at a constant 3% inflation rate needs to reach $96,762 after 10 years. A salary frozen at $72,000 is worth $53,575 in today's dollars by year 10.
