What Is the High-3 Average Salary?
Definition and calculation basics
The High-3 average salary is a key formula used in federal retirement calculations. Simply put, it’s the average of your highest-paid 36 consecutive months of basic pay. These months don’t have to be the final years of your career—they just need to be consecutive. Basic pay includes your base salary and locality pay, but not bonuses, overtime, or other extra payments. This figure forms the foundation for your federal retirement annuity.
Who uses the High-3 formula
The High-3 formula is used by several major retirement systems for federal employees, including both the Civil Service Retirement System (CSRS) and the Federal Employees Retirement System (FERS). If you’re a current federal employee or retiree, your pension is likely based on the High-3 method. This applies to most civilian federal agencies, USPS employees, and some federal-related roles, with a few exceptions.
Why Does the High-3 Matter for Retirement?
Impact on your federal annuity
Your High-3 directly affects the calculation of your federal retirement annuity. The higher your High-3, the larger your base pension payment will be. Since the annuity formula multiplies your High-3 by years of service and a set percentage (according to your retirement system), even small changes in your average pay can influence your total retirement income for years to come.
Connection to other retirement benefits
While the High-3 is most significant in pension calculation, it may also influence other retirement-related benefits. Some survivor benefits, disability annuities, and alternative payment forms are also based on your High-3. Understanding which parts of your compensation count can help you plan not just for your own retirement, but for dependents as well.
What Are Common Myths About High-3?
Myth: Bonuses always count toward High-3
It’s a common belief that all bonuses will be included in High-3 calculations. In reality, most bonuses—such as recruitment, retention, or performance bonuses—are excluded. The High-3 focuses on basic pay only, which typically does not include lump-sum awards.
Myth: High-3 includes all types of pay
Many federal employees think that overtime, differentials, or other special compensation always make it into the High-3 formula. However, only pay components described as “basic pay” by statute are included. Overtime, hazard pay, and cash awards are generally not counted. This distinction means your total compensation can be much higher than your High-3 for retirement calculation purposes.
Myth: Only your last three years matter
It seems logical that your final years might be your highest paid, but your High-3 does not have to be your final three years. The rule is simply your highest paid 36 consecutive months, which could be earlier in your career. If you moved to or from a high locality area, or took on a temporary higher-paid assignment, that period—if it meets the 36-month and consecutive requirement—could make up your High-3.
What Are the Facts About High-3?
How service periods are selected
Your High-3 is calculated based on ANY consecutive 36-month period during your federal service—not just your last three years. Agencies do this automatically, selecting the period when your basic pay was the highest. If you had a unique assignment or temporary promotion, that might set your High-3, provided it lasted 36 months in a row.
Types of pay included in High-3
Basic pay forms the basis of your High-3. This means your regular salary or wage and locality adjustments where applicable. What’s typically excluded? Overtime, bonuses, awards, or special differentials for certain conditions do not count. It’s crucial to keep this clear since your leave and earnings statements may show other forms of pay that look similar but don’t apply.
How breaks in service affect High-3
Breaks in service, such as a gap between two federal positions, reset the clock on consecutive months. However, if you leave and then return to federal service, any new period of federal work can start a potential new 36-month window. Just remember, the months used must be continuous, with no breaks for the calculation. Your full service time will factor separately into your annuity calculation, but not your High-3 period.
How Can You Estimate High-3 Yourself?
Gathering your pay records
Start by collecting your leave and earnings statements (LESs) or other official pay documents for your entire federal career, or at least the years you believe your pay was highest. Focus on the “basic pay” lines and locality pay, as these are what will count.
Calculating your average step by step
- Identify 36 consecutive months where your basic pay was at its peak.
- Add together the total basic pay (including locality pay, if applicable) across these months.
- Divide the total by 36 to get your monthly average.
- Multiply by 12 for your annual High-3 average salary.
This gives you the core number that will be used for annuity calculations.
Common pitfalls in self-estimation
It’s easy to misread your pay statements or include pay types that don’t count toward High-3. Watch for overtime, bonuses, or premium pay not labeled as basic pay. Also, double-check that your selected months are consecutive, as non-consecutive periods—even if higher individually—cannot be used together.
Can Part-Time or Interrupted Service Affect High-3?
Effect of part-time schedules
If you’ve worked part-time, your basic pay is allocated proportionally in the High-3 calculation. Only the actual earnings received count, not the full-time equivalent. This affects your final High-3 average, and, ultimately, your federal annuity.
Periods of leave without pay
Leave without pay (LWOP) may create “gaps” in your 36-month period but doesn’t necessarily disqualify those months, depending on the duration and reason for the LWOP. Short, approved LWOP periods may be smoothed over in the calculation, but extended periods can reduce your overall average.
Impact of breaks in federal service
Full breaks in federal service (resignation, separation, or extended absence from government) create a clear stop in your High-3 calculation. Only consecutive months count, and you start again with a new consecutive period when you return. If you have several episodes of federal employment, your High-3 may be based only on one specific segment, not a combination across breaks.
