How Working Hours Change Comparator Works?
The Working Hours Change Comparator works by converting each salary into real pay per hour.
Enter pay and hours before
Type the earlier salary and weekly hours.
Enter pay and hours after
Type the later salary and weekly hours.
Enter inflation
Type inflation between the 2 points.
Read the split
The output splits total pay change into an hours effect and a real hourly rate effect.
Working Hours Change Comparator Formula
The Working Hours Change Comparator formula divides each salary by hours worked per year and deflates the later rate.
Rate = Salary ÷ (Weekly Hours × 52)
Real Rate % = [Rateafter ÷ (1 + π)] ÷ Ratebefore − 1
Hours % = Hoursafter ÷ Hoursbefore − 1
Variables
- Weekly Hours
- Average paid hours per week
- π
- Inflation between the 2 points
Worked example
A salary rising from $52,000 at 40 hours to $56,000 at 45 hours looks like a 7.7% raise. Hourly pay falls from $25.00 to $23.93, and real hourly pay changes by -9.69% after 6% inflation.

What is Working Hours Change Comparator?
The Working Hours Change Comparator is a tool that separates the part of a pay change caused by more or fewer working hours from the part caused by a change in pay per hour. A higher salary earned through longer hours is not a raise in hourly terms.
The comparator reports real hourly pay before and after, so extra hours and inflation are both removed from the result.
