Required Raise Frequency Calculator
Model adjustments needed for a chosen benchmark.
Required Raise Frequency 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 Required Raise Frequency Calculator Works?
The Required Raise Frequency Calculator works by solving for the time it takes inflation to equal one raise.
Enter the raise size
Type the fixed raise per adjustment, such as 2%.
Enter the benchmark
Type the annual inflation rate to match.
Solve for the interval
The calculator finds the months at which cumulative inflation equals the raise.
Read the schedule
The output gives the interval and the raises needed per year.
Required Raise Frequency Calculator Formula
The Required Raise Frequency formula divides the log of one plus the raise by the log of one plus inflation, then converts years into months.
Months = 12 × ln(1 + R) ÷ ln(1 + i)
Raises per Year = 12 ÷ Months
Variables
- R
- Fixed raise size
- i
- Annual inflation benchmark
Worked example
At 5% inflation, 2% raises need to occur every 4.9 months, about 2.5 times per year.
Required Raise Frequency Calculator Conversion Table
This table lists the months between raises needed for 4 raise sizes at 3 inflation rates.
| Raise size | Every … months at 3% | Every … months at 5% | Every … months at 8% |
|---|---|---|---|
| 1% | 4.0 | 2.4 | 1.6 |
| 2% | 8.0 | 4.9 | 3.1 |
| 3% | 12.0 | 7.3 | 4.6 |
| 5% | 19.8 | 12.0 | 7.6 |
What is Required Raise Frequency Calculator?
The Required Raise Frequency Calculator is a tool that calculates how often a raise of a fixed size needs to occur to keep pace with a chosen inflation benchmark. The calculator answers questions such as "How often do 2% raises need to happen at 5% inflation?"
The result is an interval in months. Higher inflation or smaller raises shorten the required interval.
