Within-Grade Increases (Step Increases) for Federal Employees
Within-grade increases (WGIs), commonly called step increases, are periodic pay raises that advance a General Schedule (GS) employee from one step to the next within their current pay grade — without requiring a promotion to a higher grade. Governed by 5 U.S.C. § 5335 and implementing regulations at 5 C.F.R. Part 531, Subpart D, WGIs are a foundational component of federal compensation that reward sustained acceptable performance over defined waiting periods. Understanding the mechanics of step increases is essential for federal employees navigating their pay progression under the General Schedule framework, which covers more than 1.5 million civilian workers (OPM FedScope Workforce Data).
Definition and scope
A within-grade increase is an advancement of one step within a GS grade, contingent on two conditions: the employee must have completed the applicable waiting period, and must have demonstrated an acceptable level of competence. Each GS grade contains 10 steps, meaning an employee can receive up to 9 WGIs over the course of a career at any single grade level. WGIs apply exclusively to General Schedule employees in permanent positions; they do not apply to Senior Executive Service members, Federal Wage System employees (who operate under a separate step system), or employees in pay-banded systems such as those used by the Department of Defense under the National Security Personnel System's successor structures.
The pay differential between steps varies by grade. For GS grades 1 through 15, each step increment represents approximately 3 percent of base pay at the lower steps, though the exact dollar amounts are fixed in the annual GS pay tables published by the Office of Personnel Management. Step increases compound across a career: an employee who progresses from Step 1 to Step 10 at GS-12, for example, increases their base pay by roughly 30 percent through WGIs alone, independent of any general pay adjustments or locality pay supplements.
How it works
WGIs advance on a defined schedule based on time-in-step. The waiting periods are structured in three tiers:
- Steps 1–3: 52 weeks (1 year) required at each step before advancing to the next.
- Steps 4–6: 104 weeks (2 years) required at each step.
- Steps 7–9: 156 weeks (3 years) required at each step.
An employee who enters a grade at Step 1 and meets all eligibility requirements would reach Step 10 after a minimum of 18 years at that grade — 3 years at steps 1–3, 6 years at steps 4–6, and 9 years at steps 7–9 — before accounting for any time when WGIs were denied or delayed.
The acceptable level of competence determination is made by the employing agency based on the employee's most recent performance appraisal. Under OPM regulations at 5 C.F.R. § 531.404, an employee whose rating of record is at least "Fully Successful" (or the equivalent under the agency's appraisal system) meets the performance threshold. Time spent on approved leave without pay (LWOP) in excess of 2 workweeks in a calendar year does not count toward the waiting period and extends the WGI timeline by the number of LWOP hours exceeding that threshold.
Agencies are required to notify employees in advance when a WGI is due and must formally document any denial through a written determination.
Common scenarios
Standard progression: The most straightforward scenario is an employee who receives consistent "Fully Successful" ratings, accumulates no excessive LWOP, and advances one step automatically at the conclusion of each waiting period. No employee action is required — the increase is processed administratively by the agency's human resources office.
WGI denial: If an employee's rating of record falls below the acceptable level of competence, the agency must issue a written notice of denial. The denial does not permanently forfeit the increase; rather, the waiting period is extended. The agency must reassess at regular intervals — no less frequently than 52 weeks after the denial — and grant the WGI as soon as the employee achieves an acceptable rating. Importantly, a denial based on performance is distinct from an adverse action or disciplinary action, and does not carry the same procedural protections under 5 U.S.C. Chapter 75.
Promotion impact: When an employee is promoted to a higher GS grade, the step increase clock resets at the new grade. The promotion itself may place the employee at a step higher than Step 1 if the two-step promotion rule applies — under 5 C.F.R. § 531.214, the promoted employee's pay is set at the lowest step of the new grade that provides at least a two-step equivalent increase over their current pay. After promotion, the WGI waiting period begins anew based on the step at which the employee enters the new grade.
Temporary promotions: Employees on temporary promotions of 1 year or less who return to their permanent grade retain credit for WGI waiting time accrued in their permanent position during the temporary assignment, provided they were in a pay status.
Decision boundaries
The central decision boundary in WGI administration is the acceptable level of competence determination. Agencies must contrast two outcomes:
| Condition | Outcome |
|---|---|
| Rating of record at "Fully Successful" or equivalent | WGI granted upon completion of waiting period |
| Rating of record below "Fully Successful" | WGI withheld; reassessment required within 52 weeks |
A second boundary involves service credit. Non-pay status periods — such as extended LWOP or time spent in a uniformed military status before restoration — may or may not count toward the WGI waiting period depending on statutory protections. Under the Uniformed Services Employment and Reemployment Rights Act (USERRA, 38 U.S.C. §§ 4301–4335), returning veterans receive credit for the time spent in military service as if they had been continuously employed, which can accelerate WGI eligibility upon reemployment.
A third boundary distinguishes WGIs from promotions and special pay authorities. WGIs cannot be used to move an employee across grade boundaries, cannot substitute for a competitive promotion action, and do not affect an employee's position of record or position description. They operate strictly within the step structure of the employee's current grade and are one piece of the broader federal employee pay scales framework documented across federal compensation policy.
