Overall structure adjustment
Basic math, along with inflation, dictates that you adjust your overall salary structure on some sort of regular interval.
Several times a year, Mercer asks companies about their plans for adjusting salary structures. In the most recent version of the Compensation Planning Survey, 69% of companies responded that they adjust their pay structures annually.
The same survey asks participants what adjustment they plan to make. Of the respondents who do plan to make a pay structure adjustment, the average adjustment is 2.9%, which follows the pattern of being a percentage point or so below the merit increase budget. However, keep in mind there is some variety in the responses both by employee segment (e.g., executive, professional, etc.) and by industry. Make sure you have a data source that will provide you with intel relevant for your industry.
Useful metrics and formulas
Keeping your salary ranges and structures healthy is something you can automate by reporting on certain metrics regularly. A compensation management tool can make this a fairly automated process. Even in a spreadsheet, once you’ve identified the metrics you want to watch and set up the formulas, it can become a fairly easy part of your compensation management responsibilities.
Here are a few useful formulas to get you started.
Salary Compression Ratio: This ratio measures the difference in pay between employees in different job levels or with different levels of experience. It helps identify potential issues of pay compression within an organization. The formula is:
Salary Compression Ratio = Average Salary of Higher Level Employees / Average Salary of Lower Level Employees
Salary Range Penetration: This ratio assesses how employees' salaries compare to the salary range for their respective positions. It helps determine if employees' salaries are within the appropriate range. The formula is:
Salary Range Penetration = (Employee's Salary - Minimum Salary of the Range) / (Maximum Salary of the Range - Minimum Salary of the Range)
Compa-ratio: This ratio measures the relationship between an employee's actual salary and the midpoint of the salary range for their position. This ratio compares an employee's current salary to the target or reference point within the salary range. The formula is:
Compa-ratio = (Employee's Salary / Midpoint of Salary Range) * 100

What happens if you don’t adjust your pay structure?
Employees are in jobs that are assigned to grades or ranges in salary structures (i.e., minimum, midpoint, and maximum). Each year, the employee gets an annual salary increase while in the same job. If the salary range never changes, what eventually happens? The employee’s pay ends up at the top of the salary range.
Of course, to some degree, that is the intention – there should be a maximum value that a company will pay for any job and that is represented by the maximum of the salary range.
However, by not adjusting your salary ranges you are not accounting for changes in the economy that impact the labor market, such as inflation and a constricted supply of labor.
If your employees all end up at the top of their salary ranges, even with a career development plan in place to facilitate promotions, you’re going to have a morale situation on your hand which will likely lead to turnover.
