Salary adjustment means a change to an employee’s base pay because the employer needs to realign compensation with factors such as market rates, internal equity, job responsibilities, performance, cost pressures, or a change in role. A salary adjustment can increase pay, and in some situations it can also decrease pay, depending on the reason and the employer’s policies.
Quick answer: A salary adjustment is broader than a routine raise. It may correct pay to match the market, address internal equity, reflect a promotion or changed responsibilities, account for a cost-of-living policy, or implement another compensation decision. The key question is why the salary is changing.
What is a salary adjustment?
A salary adjustment is a change to an employee’s ongoing base salary. Employers typically use adjustments when current pay no longer fits the employee’s role, the organization’s salary structure, external market conditions, or an internal compensation decision.
The term is often used interchangeably with pay adjustment, compensation adjustment, or wage adjustment. However, the exact meaning depends on the employer. One company may use “salary adjustment” for any change to base pay, while another may reserve the term for market or equity corrections.
Salary adjustment vs. raise: what is the difference?
A raise usually describes an increase in pay. A salary adjustment is a broader term that focuses on the reason pay is being changed. A salary adjustment can therefore be a raise, but not every raise is the same type of adjustment.
| Pay change | Main reason | Usually increases base pay? |
|---|---|---|
| Routine annual raise | Annual compensation review | Yes |
| Merit raise | Performance or contribution | Yes |
| Market adjustment | Current pay is misaligned with external market rates | Often |
| Equity adjustment | Internal pay relationships need correction | Often |
| Cost-of-living adjustment (COLA) | Pay policy responds to changes in living costs or inflation | Usually |
| Promotion adjustment | Employee moves into a higher-level role | Usually |
| Role-change adjustment | Responsibilities or job scope change | May increase or decrease |
If the change is specifically tied to performance, see What Is a Merit Raise?. For promotion-specific pay changes, see Average Promotion Salary Increase in 2026.
Salary adjustment vs. merit raise vs. promotion raise vs. COLA
These pay changes can all increase salary, but they are triggered by different reasons. Keeping the categories separate makes it easier to evaluate an offer, raise letter, or compensation review.
| Type | Primary trigger | Tied to individual performance? | Requires a new role? |
|---|---|---|---|
| Salary adjustment | Broad compensation alignment, such as market, equity, role, policy, or other pay factors | Not necessarily | No |
| Merit raise | Performance, contribution, skills, or value in the current role | Usually | No |
| Promotion raise | Move to a higher-level role with greater scope or responsibility | Not necessarily | Usually |
| Cost-of-living adjustment (COLA) | Employer policy responding to changes in living costs or inflation | No | No |
An employer can combine more than one reason in the same pay review. For example, a promotion may also include a market correction, while an annual review may include both merit and a broader salary adjustment.
Common types of salary adjustments
Market salary adjustment
A market salary adjustment is used when an employee’s pay is no longer competitive with the external labor market for comparable work. Employers may review market data, geography, industry, experience level, and their own compensation strategy before deciding whether an adjustment is appropriate.
Equity salary adjustment
An equity salary adjustment addresses internal pay relationships. For example, an employer may discover that employees doing comparable work at similar levels have materially different salaries that are not explained by experience, performance, location, tenure, or other legitimate factors. A pay review can then determine whether an adjustment is needed.
Cost-of-living or inflation adjustment
Some employers use cost-of-living adjustments to help pay keep pace with changes in living costs or inflation. This is different from a merit raise because it is not necessarily tied to individual performance. Employer policies vary, so an inflation rate should not automatically be treated as the salary adjustment an employee is entitled to receive.
Merit adjustment
A merit adjustment is based primarily on performance, contribution, skills, or value to the organization. It is often part of a structured annual review process.
Promotion or job-change adjustment
A promotion may move an employee into a new salary range or pay grade. A lateral transfer, reclassification, expanded role, or reduction in responsibility can also trigger a salary review even when the employee’s title changes only slightly.
Compliance or policy adjustment
An employer may also change pay to comply with an applicable wage rule, collective agreement, internal pay policy, or another compensation requirement. The exact legal requirements depend on location and employment circumstances.
Temporary vs. permanent salary adjustments
Most salary adjustments discussed in compensation planning are permanent changes to base pay. But some pay changes are temporary. An employee might receive temporary additional pay for acting duties, a short-term assignment, a location differential, or another limited situation.
Before comparing two offers or pay letters, check whether the adjustment changes ongoing base salary or only adds temporary compensation. The financial effect can be very different.
How do employers determine a salary adjustment?
There is no single formula that every employer uses. A compensation review may consider several factors together:
- External market data: What comparable jobs are paying in the relevant market.
- Salary range: The minimum, midpoint, and maximum assigned to the role or grade.
- Compa ratio: How current salary compares with the midpoint of the employee’s salary range.
- Internal equity: How pay compares with employees performing similar work at similar levels.
- Experience and skills: Relevant expertise, credentials, scarce skills, and time in role.
- Performance: Whether the organization includes performance in the adjustment decision.
- Job scope: Changes in responsibility, complexity, team size, or decision-making authority.
- Budget and pay policy: The employer’s compensation budget and internal guidelines.
If your employer provides a salary range, you can calculate compa ratio to see where your current salary sits relative to the midpoint.
Market salary adjustment example
Suppose an employee earns $62,000 and the employer completes a market review. After comparing the role with current market data and the organization’s pay structure, the employer decides to move the salary to $66,000.
- Old salary: $62,000
- New salary: $66,000
- Dollar adjustment: $4,000
- Percentage adjustment: 6.45%
The 6.45% figure describes the size of the change. It does not mean every employee with a similar market gap should receive the same percentage.
Equity salary adjustment example
Imagine two employees are in the same salary grade and perform comparable work. One earns $70,000 and the other earns $77,000. The difference alone does not prove a pay-equity problem. Experience, performance, tenure, location, specialized skills, or other factors may explain it.
If a compensation review finds that the difference is not supported by relevant factors, the employer may consider an equity adjustment. The purpose is to improve internal pay alignment, not simply to make every salary identical.
What is a retroactive salary adjustment?
A retroactive salary adjustment is a pay change that takes effect from an earlier date than the date it is processed. This can happen when an approved adjustment is delayed in payroll, a promotion is made effective from an earlier date, or another compensation decision needs to be applied back to its effective date.
For example, suppose a salary increases from $60,000 to $63,000 effective July 1, but payroll does not implement the change until August 1. The employer may owe the difference for the affected July pay period or periods, depending on the organization’s payroll process and applicable rules.
How to calculate a salary adjustment
If you know the old and new salary, first calculate the dollar change:
Salary adjustment amount = New salary − Old salary
Then calculate the percentage change:
Salary adjustment percentage = ((New salary − Old salary) ÷ Old salary) × 100
Example: if salary changes from $70,000 to $75,000, the increase is $5,000. $5,000 ÷ $70,000 × 100 = approximately 7.14%.

Salary adjustment justification examples
A salary adjustment justification should explain the business or compensation reason for changing pay. Common examples include:
- Market alignment: “Current salary is below the organization’s target market position for this role and experience level.”
- Expanded responsibilities: “The role now includes responsibility for a larger team, budget, or business function.”
- Internal equity: “A compensation review identified an unexplained pay gap within comparable positions.”
- Promotion: “The employee has moved into a higher-level role with a different salary range.”
- Retention or scarce skills: “The role requires specialized capabilities that have become more difficult to recruit or retain.”
A strong justification connects the adjustment to the job, the pay structure, measurable responsibilities, or credible market information rather than relying only on personal expenses.
Can an employee ask for a salary adjustment?
Yes, an employee can request a compensation review, but the strongest case usually explains why current pay may no longer match the role. Useful evidence can include expanded responsibilities, measurable results, a promotion or reclassification, current market data, or the employer’s own salary range.
This article focuses on what salary adjustments are and how they work. For wording, email examples, and a step-by-step request process, use our Salary Increase Request Letter guide.
Salary adjustment vs. compa ratio
A salary adjustment is the actual change in pay. A compa ratio is a measurement used to compare salary with the midpoint of a salary range. The two are related but not interchangeable.
For example, an employee with a low compa ratio may be reviewed for a market or equity adjustment, but the ratio alone does not determine how much the salary should change. Employers still need to consider experience, performance, market data, internal equity, and compensation policy.
How a salary adjustment affects your paycheck
A permanent salary increase raises gross base pay going forward. The exact change in take-home pay can be smaller than the gross increase because taxes, benefits, retirement contributions, and other payroll deductions may also change.
When reviewing an adjustment letter, confirm the new annual salary, effective date, pay frequency, and whether any part of the change is temporary. Those details are more useful than looking only at the percentage.
Common salary adjustment mistakes
- Assuming every adjustment is a merit raise: Market, equity, promotion, and cost-of-living adjustments have different purposes.
- Using the wrong market comparison: Job level, geography, industry, and responsibilities can materially change market pay.
- Treating inflation as an automatic entitlement: Employer compensation policies may use different criteria.
- Ignoring the salary range: A percentage increase can look large while the resulting salary still sits low in the relevant range.
- Confusing a bonus with base-pay adjustment: A one-time payment does not automatically raise ongoing salary.
- Ignoring the effective date: The effective date determines when the new rate begins and whether retroactive pay may apply.
Frequently asked questions
What is salary adjustment?
A salary adjustment is a change to base pay made for a compensation reason such as market alignment, internal equity, performance, promotion, role changes, cost-of-living policy, or another employer pay decision.
Is a salary adjustment the same as a salary increase?
Not always. A salary increase specifically means pay goes up. A salary adjustment is broader and describes a change made for a particular compensation reason. Many salary adjustments are increases, but the terms are not identical.
What is a market salary adjustment?
A market salary adjustment changes pay to improve alignment with external market rates for comparable work. Employers may consider job level, location, industry, experience, market data, and internal salary structures.
What is an equity salary adjustment?
An equity salary adjustment is intended to address an internal pay relationship that needs review or correction. It should be based on a broader compensation analysis rather than salary differences alone.
Can a salary adjustment reduce pay?
It can in some circumstances, such as a change in role, work arrangement, or pay structure, although many salary adjustments are increases. Whether a reduction is permitted depends on the employment arrangement, employer policy, and applicable law.
What is a retroactive salary adjustment?
It is a salary change processed after its effective date. Payroll may then need to apply the difference for the period between the effective date and the date the new rate was implemented.
How often should salary adjustments happen?
There is no universal schedule. Some employers review pay annually, while market, equity, promotion, or role-change adjustments can occur when a specific need is identified.
