The Mathematics of Salary Increases
Salary raise calculations differ slightly based on whether the increase is a percentage value or a flat cash amount. Normalizing all variables to an annual index allows side-by-side comparison:
1. Convert Current Input to Annual Basis:
- Annual: Annual Salary
- Monthly: Monthly Salary * 12
- Weekly: Weekly Salary * Weeks per Year (standard 52)
- Hourly: Hourly Rate * Hours per Week (standard 40) * Weeks per Year (standard 52)
2. Solve Raise Increment:
- Percentage Increase: Raise Annual = Current Annual * (Percentage / 100)
- Flat Increase:
- If hourly input cycle: Raise Annual = Flat Hourly Increase * Hours/Week * Weeks/Year
- If annual input cycle: Raise Annual = Flat Annual Increase
3. Divide New Totals Across Pay Cycles:
New Annual = Current Annual + Raise Annual
New Monthly = New Annual / 12
New Weekly = New Annual / Weeks per Year
New Hourly = New Annual / (Hours per Week * Weeks per Year)
New Monthly = New Annual / 12
New Weekly = New Annual / Weeks per Year
New Hourly = New Annual / (Hours per Week * Weeks per Year)
