I The waiting period schedule
Three tiers, and they slow as you advance.
| Moving to | Waiting period | In practice |
|---|---|---|
| Steps 2, 3, 4 | 52 weeks | About one year each |
| Steps 5, 6, 7 | 104 weeks | About two years each |
| Steps 8, 9, 10 | 156 weeks | About three years each |
Add it up and the full progression from step 1 to step 10 takes 18 years of uninterrupted creditable service in the same grade. That is longer than most people spend at a single grade, which is why relatively few employees ever reach step 10 through within-grade increases alone.
Within-grade increases are earned by time, conditioned on performance — which makes them nearly automatic in practice and entirely dependent on a rating of record you should never let drift unexamined.
The effective date is the beginning of the first pay period after the waiting period is completed. Your servicing HR office tracks it, and it appears as an action on your SF-50 when it happens.
II Acceptable level of competence
Two conditions must be met for a WIGI: the waiting period is complete, and your performance is determined to be at an acceptable level of competence.
That determination generally rests on your most recent rating of record being at least Fully Successful or the equivalent under your agency's appraisal system. If your rating meets that standard, the increase follows.
Employees routinely accept a Fully Successful rating without much thought because it sounds adequate. It is also the floor for your step increase, and a rating below it stops your pay progression outright. If a rating drops toward that line, it is no longer only a performance conversation — it is a pay conversation, and it is worth treating as one. Performance ratings generally are covered in Topic 37.
III If an increase is withheld
A withholding is a negative determination of acceptable level of competence, and it is a formal action rather than an administrative pause.
What you are entitled to:
- Written notice explaining the reasons for the determination.
- Reconsideration of the decision on request.
- Retroactive payment if the determination is later reversed — the increase is granted effective the date it would otherwise have taken effect.
Agencies are generally expected to have raised performance concerns before this point. A withholding that arrives with no prior discussion is worth questioning on that basis alone.
If your most recent rating of record is Fully Successful or higher and an increase is withheld anyway, those two facts are hard to reconcile. Raise it in writing, immediately, citing your rating. That is the cleanest version of this dispute and it frequently resolves without escalation. If you are in a bargaining unit, your representative handles these routinely — see Workplace Topic 06.
IV What counts toward the waiting period
Creditable service toward a waiting period generally includes time in a pay status, and paid leave counts. Ordinary annual and sick leave use does not delay a within-grade increase.
What can extend it:
- Extended nonpay status. Time in leave without pay accrues differently, and beyond a threshold amount it extends the waiting period.
- Suspensions and other periods not in a pay status.
- Breaks in service, depending on length and circumstances.
If you have had a significant period of leave without pay — extended medical leave, military leave without pay, a long unpaid absence — ask your servicing HR office to confirm your current waiting period completion date. The original anniversary you have in mind may no longer be correct, and finding out at the time is far better than discovering a missed increase a year later.
V What resets the clock
An equivalent increase resets your waiting period and starts a new one. Knowing what counts is how you avoid a surprise.
| Event | Resets the waiting period? |
|---|---|
| Promotion to a higher grade | Yes — new clock at the new grade and step |
| Quality step increase | Yes — a QSI is an equivalent increase |
| Annual general pay adjustment | No |
| Locality percentage change | No |
| Lateral reassignment, same grade and step | No |
| Ordinary within-grade increase | Starts the next waiting period, as expected |
The promotion reset is the one people find counterintuitive. Promotion is unambiguously good — it raises your grade and typically your pay by far more than a step — but it does restart step progression from zero at the new grade. An employee promoted at GS-12 Step 8 does not arrive at GS-13 Step 8; the two-step rule places them, and a fresh waiting period begins.
VI Step Increase Tracker
Enter your grade, step, and the date your current waiting period began. The tool projects your next increase and the value it carries.
When is your next step?
Projections assume uninterrupted creditable service. Confirm your actual date with HR.
Years to Reach Each Step From Step 1
Cumulative years of uninterrupted creditable service required to reach each step within a grade, using the 52, 104, and 156 week waiting periods. Progression slows sharply after step 4, and reaching step 10 takes 18 years in a single grade.
VII The quality step increase
A QSI moves you one step higher within your grade as recognition of sustained high-quality performance. It is a different instrument from a WIGI in every respect that matters.
| Within-grade increase | Quality step increase | |
|---|---|---|
| Basis | Time plus acceptable competence | Sustained high-quality performance |
| Discretion | Effectively an entitlement once earned | Agency discretion |
| Rating needed | Fully Successful or equivalent | Generally the highest rating level |
| Waiting period | Required | None |
| Effect on the clock | Starts the next one | Resets it — equivalent increase |
| Effect on basic pay | Permanent | Permanent |
This is the comparison worth understanding, because agencies frequently choose between them. A cash award is a one-time payment that never touches your basic pay. A QSI raises basic pay permanently — which means it compounds into every future promotion computed under the two-step rule, and into your High-3. For an employee with years of service remaining, a QSI is usually worth considerably more than a cash award of similar headline value. If you are being recognized and the form is open for discussion, that is worth saying. Awards generally are covered in Topic 16.
VIII The QSI trade-off
Because a QSI is an equivalent increase, it restarts your waiting period. The cost depends entirely on timing.
The same award, two different values
Good timing: you received a WIGI two months ago and are early in a new 104-week waiting period. A QSI moves you up a step now and restarts a clock you had barely started. You gain a step and lose almost nothing.
Poor timing: you are 100 weeks into a 104-week waiting period. A QSI moves you up a step now — and restarts the clock, erasing nearly two years of accrued waiting time toward the step you were about to receive anyway.
This almost never argues for declining a QSI — a permanent basic pay increase is a permanent basic pay increase. But if the timing is discussable, receiving one shortly after a within-grade increase is materially better than receiving one shortly before.
IX Steps and promotions together
Steps and promotions interact in a way that creates real timing leverage, and almost nobody uses it.
When a promotion and a within-grade increase are effective the same day, the agency must process the WIGI first under 5 CFR 531.214(c). That raises the rate the two-step promotion rule is computed from — and can land you a full step higher in the new grade.
"When is my next within-grade increase due, and can the promotion effective date be set on or after it?" HR can answer both in about a minute. If your WIGI is a pay period or two out, aligning the dates costs nothing and can be worth a step for the rest of your career — because every subsequent promotion computes from the higher rate. The full mechanics are in Topic 39.
The corollary is that a promotion processed just before a WIGI vests captures none of that. Where you have any influence over the effective date, that is where to use it.
X What a step is actually worth
Each step is roughly 3 percent of the grade's base rate — the ten steps span about a 30 percent range from step 1 to step 10, divided into nine increments.
On a GS-13 that is roughly $3,000 per step before locality, and more after it. But the annual figure understates the value in three ways:
- It compounds into promotions. Every future promotion applies the two-step rule to your then-current rate, so a step gained today raises the base for every promotion after it.
- It carries into your High-3. Basic pay is what the annuity is computed from — see Topic 35.
- It is multiplied by locality. A step worth $3,000 in base pay is worth about $4,000 in a 33.94 percent locality area.
Because the two-step rule computes from your existing rate, an employee promoted at GS-12 Step 8 lands materially higher in the GS-13 range than one promoted at Step 2. That is not an argument for turning down an early promotion — more years at a higher grade usually dominates — but where you genuinely have a choice between now and after your next step, run both numbers.
XI At the top of the grade
Step 10 is the ceiling. There are no further within-grade increases, and a QSI cannot move you beyond it either.
From there, basic pay rises only through:
- Annual pay adjustments to the base table and locality percentages.
- Promotion to a higher grade.
- A move to a higher-locality duty station, which raises payable pay without changing the grade or step.
- A special rate schedule, if your occupational series qualifies — see Topic 05.
Employees who reach step 10 and stay there often do not notice for years that their pay progression has stopped except for annual adjustments. If you are at or near step 10 and not pursuing a promotion, that is worth recognizing deliberately — particularly within the three years that set your High-3.
XII The playbook
| Situation | What to do |
|---|---|
| You do not know your next WIGI date | Ask HR. It drives promotion timing and is easy to confirm. |
| Promotion being discussed | Ask whether the effective date can be aligned with or after your WIGI. |
| Rating drifting toward Fully Successful | Treat it as a pay conversation, not just a performance one. |
| Increase withheld with a Fully Successful rating | Raise it in writing immediately, citing the rating. |
| Increase withheld generally | You are entitled to written reasons and reconsideration. Retroactive if reversed. |
| Offered a QSI or a cash award | The QSI raises basic pay permanently. Usually worth more. |
| Extended leave without pay | Confirm your revised waiting period completion date with HR. |
| At step 10 | Progression has stopped. Promotion, locality, or a special rate are the remaining levers. |
What to confirm
- Find out the exact date your current waiting period completes — HR tracks it and can tell you in a minute.
- Know which tier you are in: 52 weeks for steps 2 to 4, 104 for 5 to 7, 156 for 8 to 10.
- Check that your most recent rating of record is at least Fully Successful — it is the floor for your increase.
- If a promotion is in play, ask whether the effective date can be set on or after your WIGI.
- If an increase is withheld, request the written reasons and reconsideration, and note it is retroactive if reversed.
- If you had extended leave without pay, confirm whether your completion date moved.
- If you are being recognized, ask whether a QSI is available rather than a cash award — it is permanent.
- Remember a QSI and a promotion both reset the waiting period; timing determines how much you net.
- Note that each step is roughly 3% of your grade, and more after locality is applied.
- If you are at step 10, recognize that progression has stopped and plan the next lever deliberately.
Frequently asked questions
The waiting period depends on which step you currently hold. Moving from step 1 to 2, 2 to 3, or 3 to 4 requires 52 weeks of creditable service. Moving from step 4 to 5, 5 to 6, or 6 to 7 requires 104 weeks. Moving from step 7 to 8, 8 to 9, or 9 to 10 requires 156 weeks. Step 10 is the top of the grade and there are no further within-grade increases. That structure means the early steps arrive annually and the later ones every three years, so progression through a grade slows considerably as you advance.
Nearly, but not quite. A WIGI requires that you have completed the waiting period and that your performance is at an acceptable level of competence, which means your most recent rating of record is at least Fully Successful or the equivalent under your agency's system. In practice the overwhelming majority are granted without incident. The distinction matters because an agency can withhold one for performance reasons, and when it does, that decision carries procedural rights rather than being a routine administrative action.
A withholding is a negative determination of acceptable level of competence and it comes with process. You are entitled to written notice explaining the reasons and to request reconsideration of the decision. Agencies are generally expected to have communicated performance concerns before this point rather than delivering a surprise. If the determination is later reversed, the increase is granted retroactive to the date it would otherwise have been effective. If your rating of record is Fully Successful and an increase is withheld anyway, that inconsistency is worth raising immediately in writing.
An equivalent increase resets the clock and starts a new waiting period. A promotion is the most common example — when you move to a higher grade your waiting period begins again at the new grade and step. A quality step increase also constitutes an equivalent increase and restarts the waiting period, which is one of the genuine trade-offs of receiving one. Ordinary annual pay adjustments do not reset anything, and neither does a lateral reassignment at the same grade and step.
A QSI is a discretionary award that moves you one step higher within your grade, in recognition of sustained high-quality performance. Unlike a within-grade increase it is not tied to a waiting period, it is granted at agency discretion rather than earned by time, and it generally requires a rating of record at the highest level. It is also distinct from a cash award in an important way: a QSI raises your basic pay permanently, which means it compounds into future promotions and your High-3, while a cash award is a one-time payment.
It can, because a QSI is an equivalent increase and restarts your waiting period. The practical effect depends on where you are in the cycle. Receiving a QSI shortly after a within-grade increase costs you relatively little, since you were near the start of a new waiting period anyway. Receiving one shortly before a within-grade increase was due means you gain a step now but restart a waiting period you had nearly completed. The QSI is still worth accepting in almost every case, but the timing determines how much you actually net.
Each step is roughly 3 percent of the grade's base rate, since the ten steps span about a 30 percent range from step 1 to step 10. On a GS-13 that is roughly $3,000 per step before locality, and more after it. The larger value is compounding: because every future promotion applies the two-step rule to your then-current rate, a step gained today propagates into every promotion you receive afterward, and eventually into the High-3 that computes your annuity.
Paid leave generally counts as creditable service toward a waiting period, so ordinary annual and sick leave do not delay a within-grade increase. Extended periods of nonpay status can extend the waiting period beyond a threshold amount, and time in a nonpay status such as leave without pay accrues differently. If you have had a significant period of leave without pay, ask your servicing HR office to confirm your current waiting period completion date rather than assuming your original anniversary still applies.
