Salary vs inflation: will your raises keep up?

Inflation erodes purchasing power even when your paycheck grows. This calculator compares the salary you need to maintain today's standard of living against the salary you will actually earn if raises compound at your expected rate. It shows nominal future pay, inflation-adjusted real purchasing power, and the gap between the two.

To model a single raise across pay periods, use the pay raise calculator. For long-term salary projections with multiple raises, try the future salary calculator.

Salary inflation formulas

Required salary=Current salary×(1+Inflation100)Years\text{Required salary} = \text{Current salary} \times \left(1 + \frac{\text{Inflation}}{100}\right)^{\text{Years}}
Future nominal=Current salary×(1+Raise100)Years\text{Future nominal} = \text{Current salary} \times \left(1 + \frac{\text{Raise}}{100}\right)^{\text{Years}}
Future real=Future nominal(1+Inflation100)Years\text{Future real} = \frac{\text{Future nominal}}{\left(1 + \frac{\text{Inflation}}{100}\right)^{\text{Years}}}
Gap=Required salary−Future nominal\text{Gap} = \text{Required salary} - \text{Future nominal}

Worked example

Starting at $65,000 with 3.5% annual inflation and 2.5% raises over 5 years: required salary is $77,199.61 to preserve purchasing power. Nominal salary after raises reaches $73,541.53, but its real value is only $61,919.99 in today's dollars. The shortfall is $3,658.08.

Frequently asked questions

What does future real purchasing power mean?
It is your future nominal salary deflated back to today's dollars using the inflation factor. It shows what your future paycheck would feel like in current purchasing power.
What if my raise rate exceeds inflation?
The gap turns negative, meaning your real purchasing power grows. The calculator shows a positive surplus instead of a shortfall.
Should I use CPI or a custom inflation rate?
Use the average inflation rate you expect over the time horizon. Historical U.S. CPI averages around 2 to 3%, but you can enter any rate that matches your planning assumptions.
Does this account for taxes?
No. All figures are pre-tax salary amounts. After-tax purchasing power also depends on bracket changes and deductions.
How is cumulative inflation calculated?
Cumulative inflation equals the inflation factor minus one, expressed as a percentage. For 3.5% over 5 years, the factor is about 1.188, or 18.8% cumulative inflation.
