Inflation Break-Even Calculator
Find inflation matching a given raise.
Inflation Break-Even Calculator: Scenario Inputs
Annual percentage rate or benchmark index change.
Inflation & Purchasing Power Analysis
Over 3 years at 3.5% inflation, a $75,000 salary requires $83,154 to retain equal purchasing power. Without matching raises, your real compensation experiences an effective reduction of $7,355 (-9.81%).

How Inflation Break-Even Calculator Works?
The Inflation Break-Even Calculator works by annualizing the total raise over the years it covers.
Enter the raise
Type a single raise or a total raise package.
Enter the years covered
Type the number of years the package lasts.
Annualize the raise
The calculator takes the n-th root of 1 + total raise.
Read the break-even rate
The output gives the annual inflation rate that matches the raise, and the real result at other inflation levels.
Inflation Break-Even Calculator Formula
The Inflation Break-Even formula takes the n-th root of one plus the total raise and subtracts one.
Break-Even % = [(1 + R)1/n − 1] × 100
Real % = [(1 + R) ÷ (1 + π)n − 1] × 100
Variables
- R
- Total raise over the package
- n
- Years the package covers
- π
- Actual annual inflation
Worked example
A 10% raise package spread over 3 years breaks even at 3.23% annual inflation. At 4% inflation the package leaves real pay -2.21% after 3 years.
Inflation Break-Even Calculator Conversion Table
This table lists the break-even inflation rate for 6 raise packages and the real result at 3.5% annual inflation.
| Raise package | Break-even annual inflation | Real result at 3.5% inflation |
|---|---|---|
| 3% over 1 year | 3.00% | -0.48% |
| 7% over 2 years | 3.44% | -0.11% |
| 10% over 3 years | 3.23% | -0.79% |
| 12% over 3 years | 3.85% | +1.02% |
| 15% over 4 years | 3.56% | +0.22% |
| 20% over 5 years | 3.71% | +1.04% |
What is Inflation Break-Even Calculator?
The Inflation Break-Even Calculator is a tool that finds the annual inflation rate at which a given raise, or raise package, leaves purchasing power unchanged. Inflation above the break-even rate turns the raise into a real loss.
The calculator handles multi-year raise packages, such as 10% spread over 3 years, by converting the package into one yearly break-even rate.
What are the uses of Inflation Break-Even Calculator?
