Salary Inflation Adjuster

What this calculator does

This calculator shows what inflation does to a salary over time. Enter your current salary, an expected annual inflation rate, and a number of years, and it returns the real value of that salary at the end of the period, the higher nominal salary you would need to preserve today's purchasing power, and the erosion between the two.

The two outputs answer different questions. The real value tells you what a frozen salary would actually buy in future money. The required future salary tells you what number to aim for in negotiations. Both come from the same compounding relationship, and both are considerably more dramatic over ten or twenty years than intuition suggests.

When to use it

The most practical use is preparing for a pay review. Knowing that a 3 percent offer against 3.5 percent inflation is a real pay cut turns a vague dissatisfaction into a specific point you can raise with a number attached.

It also makes historical comparisons honest. Converting a salary you earned a decade ago into today's dollars is how you tell whether your career has actually progressed or merely tracked prices. And it is essential for long-range planning: an income target for retirement or for a child's college costs stated in today's money has to be inflated to the year it will be spent, or the plan is built on a number that will not be enough.

Understanding the inputs

Current salary should be your gross annual figure. The inflation rate is the assumption that drives everything, so choose it deliberately. The Federal Reserve targets 2 percent, long-run US averages sit closer to 3 percent, and recent years have swung well outside both.

Running the calculation at 2, 3, and 4 percent gives you a range rather than a false precision, which is more useful for planning. The years field should match your actual horizon: a two-year gap between pay reviews behaves very differently from a twenty-year retirement projection, and the compounding is what makes the long horizon so much harsher than a linear estimate would suggest.

How is this calculated?

Real Value = Nominal Value / (1 + Inflation Rate)^Years.

A worked example

Take an $85,000 salary with inflation at 3 percent over ten years. To buy the same basket of goods in year ten, you would need about $114,200, since prices compound to roughly 1.34 times their starting level.

Turned around, a salary frozen at $85,000 for those ten years would be worth about $63,250 in today's money, an erosion of nearly $21,800, or 25.6 percent of its purchasing power. That is what a decade of flat pay costs. Note also that receiving 3 percent raises every year in a 3 percent inflation environment leaves you exactly level: ten years of raises, no gain at all in what the salary buys.

Limitations and assumptions

This applies a single constant inflation rate, which no real economy delivers. US inflation ran below 2 percent through much of the 2010s and above 8 percent in 2022, and the compounding path matters as well as the average. Treat outputs as central estimates, not forecasts.

It also uses a national average price index, and your personal inflation rate can differ substantially. Healthcare, childcare, and higher education have risen far faster than the general index for decades, while consumer electronics have fallen. A household weighted toward the fast-rising categories experiences meaningfully higher inflation than CPI reports. The calculator ignores tax entirely, so a nominal salary that keeps pace with inflation may still lose ground where a threshold is not indexed.
