Within-grade increase, defined: A WGI is a periodic increase in a General Schedule employee's rate of basic pay from one step of their grade to the next, granted after completing the required waiting period (52, 104, or 156 weeks depending on the current step) with performance at an acceptable level of competence. It is distinct from a promotion (a grade change) and from the annual government-wide pay adjustment.

Who This Article Is For

• GS employees who want to know when their next raise arrives and what it's worth
• Feds trying to reconcile the three different raises that hit a federal paycheck — annual adjustment, WGI, promotion
• Mid-career employees at steps 4–9 wondering why the raises slowed down
• Employees within a few years of retirement who don't realize a step increase is also a pension increase
• Supervisors and new hires who've heard "steps are automatic" and want to know how true that is

1. The Three Kinds of Federal Raises

Federal pay moves through three separate mechanisms, and they're worth keeping distinct because they follow different rules:

1. The annual pay adjustment — the government-wide raise each January (1.0% in 2026), set by law or executive order. You do nothing to earn it; it moves the entire pay table.
2. The within-grade increase — your personal climb through the 10 steps of your grade on a fixed clock. This article.
3. Promotion — a grade change, typically worth two-plus steps immediately under the two-step rule.

A mid-career fed's salary trajectory is the braid of all three. The WGI is the quiet one: nobody announces it, it doesn't require an application, and many employees couldn't tell you their next WGI date — even though it's precisely calculable.

2. The Waiting Periods: 1, 2, 3

The schedule is set by regulation (5 CFR 531.405) and depends only on the step you're currently in:

Reference table from 5 CFR 531.405. Waiting periods can be reduced by quality step increases or extended by certain suspensions — confirm your own WGI date with your agency HR office.

Add it up and the full climb from Step 1 to Step 10 takes 18 years: three 1-year waits, three 2-year waits, three 3-year waits. That's why raises feel frequent in your first few years at a grade and sparse later — the design front-loads the progression.

The clock runs in weeks of creditable service in the step, and it restarts in a few situations worth knowing:

• Promotion. A promotion is an "equivalent increase" — your WGI clock resets at the new grade's step.
• Certain pay actions. Quality step increases (see Section 6) advance your step but also restart the waiting period at the new step's schedule.
• Extended LWOP beyond the allowed hours can push the date back.

Your WGI due date is knowable to the day from your last SF-50's step effective date — that's exactly what the WGI Calculator computes, along with the dollar value of the raise waiting at the end of it.

3. What a Step Is Worth

Each step within a grade is one-ninth of the gap between Step 1 and Step 10 — a fixed dollar amount within each grade, not a percentage. In the 2026 tables, the GS-12 range runs from $76,463 to $99,404, so:

GS-12 step value = ($99,404 − $76,463) ÷ 9 = $2,549 of base pay

Base pay isn't take-home reality, though — your locality percentage multiplies every step. Illustrative example, using the official 2026 tables and the OPM rounding formula; your figures depend on grade, step, and duty station:

Roughly 3% of salary, arriving on a fixed schedule, independent of the annual adjustment — a GS-12 Step 5 in DC who receives the 2026 1.0% adjustment and a WGI in the same year gets about 4% total. This is the mechanism behind the observation that federal pay grows faster than the headline raise suggests, at least until you reach the long waits of steps 7–10.

4. "Automatic" — How True Is It?

A WGI requires a determination that your performance is at an acceptable level of competence — in practice, a rating of record at the fully-successful level or better. If your performance meets that bar, the increase is granted effective the first pay period after the waiting period completes. There's no application, no negotiation, and no budget dependency.

Denials are rare and procedurally heavy: the agency must notify you in writing, and a denial can be reconsidered and grieved. If a WGI is denied, it isn't gone forever — once performance returns to an acceptable level, the increase can be granted.

So "automatic" is nearly right. The practical failure mode isn't denial — it's employees not noticing that a promotion reset their clock, or not realizing they've been sitting one pay period away from a WGI when weighing a job change. Timing a departure a few weeks after a step increase rather than before it changes your High-3 arithmetic.

5. The Part Nobody Mentions: WGIs Are Pension Raises

Every WGI raises your rate of basic pay, and basic pay is what the FERS pension formula averages over your highest 36 consecutive months. That gives step increases a second life:

Illustrative example only. Standard 1.0% multiplier, 30-year career, GS-12 DC figures from above. Your actual impact depends on when the step lands relative to your High-3 window. Not financial advice.

Take the $3,414 GS-12 DC step increase. If it's in effect for your entire final 36 months, it raises your High-3 by the full $3,414. For a 30-year employee at the 1.0% multiplier:

$3,414 × 1.0% × 30 years = about $1,024/year of additional pension — for life, with survivor benefits and COLAs computed on top of it.

Over a 25-year retirement that single step increase is worth roughly $25,000 of pension payments before COLAs. This is why the timing of your last step matters: a WGI granted two years before retirement is mostly inside your High-3 window; the same WGI granted two months before retirement barely moves the average. If you're choosing a retirement date and a step increase is close, run the numbers first — the High-3 Calculator handles the time-weighting.

6. Quality Step Increases and Other Accelerants

Two ways the ordinary schedule can compress:

• Quality Step Increase (QSI). An agency can award an additional step for sustained outstanding performance — the only way to receive two steps in a single waiting period. A QSI doesn't just add money early; at steps 4–9 it effectively saves you a multi-year wait.
• Promotion. Under the two-step rule, promotion pay is set at least two WGIs above your current rate. If you're deep into a long waiting period, a promotion captures that progress a different way.

One caution on QSIs: because the QSI restarts your waiting period, a QSI granted shortly before you'd have earned the WGI anyway is worth less than it looks.

7. Common WGI Mistakes

1. Not knowing your date. It's calculable from your last step effective date (SF-50). Waiting-period lengths change at steps 4 and 7 — that's where expectations drift.
2. Assuming the WGI clock survives a promotion. It doesn't. A promotion is an equivalent increase and restarts the wait at the new step.
3. Quitting or retiring just before a step lands. A WGI a few pay periods away is real money — and if you're near retirement, it's High-3 money.
4. Confusing steps with performance awards. Cash awards don't touch basic pay and never enter your pension. A step does both.
5. Forgetting steps flatten at the top. At Step 10 the climb ends; from there, only promotions, the annual adjustment, or a locality change move your pay. (And at GS-15 in high-locality areas, the pay cap can flatten it sooner.)

Frequently Asked Questions

How often do GS step increases happen? Every 52 weeks at steps 1–3, every 104 weeks at steps 4–6, and every 156 weeks at steps 7–9. Step 10 is the top; there is no further WGI.

How much is a step increase worth? One-ninth of your grade's Step 1-to-Step 10 range. At GS-12 in 2026 that's $2,549 of base pay — about $3,414/year in the Washington-DC locality area, or roughly a 2.9% raise.

Are step increases automatic? Effectively yes: they're granted when the waiting period completes, provided your performance is at an acceptable level of competence. A denial requires written notice and is subject to reconsideration.

How long does it take to reach Step 10? 18 years within one grade: 3 one-year waits, 3 two-year waits, and 3 three-year waits.

Does a promotion reset my WGI clock? Yes. A promotion is an "equivalent increase," and your waiting period restarts at the new grade and step.

Do step increases count toward my pension? Yes — a WGI raises your rate of basic pay, which is what your High-3 average is built from. A step increase fully inside your final 36 months raises your High-3 by its full amount.

What is a Quality Step Increase? An extra step awarded for outstanding performance — the only way to advance two steps within one waiting period. It restarts your WGI waiting period at the new step.

Can I get a WGI at Step 10? No. Step 10 is the maximum for every grade. Further increases come only from promotions, the annual adjustment, or a move to a higher-locality area.

Where do I find my current step and its effective date? Your most recent SF-50 shows your grade, step, and the effective date of your last step action — that date starts your current waiting period.

The Bottom Line

The WGI is the most predictable raise in American employment: a fixed schedule, a knowable date, and a dollar value you can read off a table. Treat it that way. Know your date, know what the step is worth in your locality, and — if retirement is within sight — know that your last few steps are doing double duty, raising the High-3 that every year of your pension will be computed from. A raise you can predict is a raise you can plan around.
