The Office of Human Resources often receives questions about how the General Schedule (GS) locality pay tables are updated.  The process begins with updating the GS non-locality base pay table. 

By law, GS pay in all geographic locations is increased across-the-board based on nationwide changes in the cost of non-federal salaries as reflected by the Employment Cost Index (ECI).  However, the President has authority to issue an alternative across-the-board increase, and he exercised that authority for 2024, ordering a 4.7 percent increase via Executive Order.  The 2023 step 1 rate for each grade was increased by 4.7 percent and rounded to the nearest dollar to derive the 2024 step 1 rates.  Each new 2024 step 1 rate was then divided by 30 to produce a standard Within-Grade Amount for each grade.  The standard Within-Grade amount is then added to step 1 to derive the step 2 rate, added to step 2 to derive the step 3 rate, and so forth.  GS-1 and GS-2 have some differences in their calculations that will not be discussed here.  This two-step process results in the GS 2024 non-locality base pay table.  This table is the basis for creating all the GS locality pay tables.

The previous section described the process to update the GS non-locality base pay table.  This section describes how the GS locality pay tables are created.  Most GS employees are entitled to locality pay.  Many people believe that locality pay is meant to compensate for the higher costs of living in various parts of the country.  In fact, locality pay is based on a percentage rate that reflects pay levels for non-federal employees in different geographic areas as determined by pay surveys conducted by the U.S. Bureau of Labor Statistics.  The D.C. area locality pay percentage increased from 32.49 percent in 2023 to 33.26 percent in 2024 based on these salary surveys.  Each salary figure on the GS 2024 non-locality pay table was multiplied by 1.3326 to create the 2024 Washington DC area locality pay table, which covers DC and surrounding areas in parts of Maryland, Virginia, West Virginia and Pennsylvania.  The locality table construction differs from the GS non-locality base table, in which steps 2-10 are derived by adding the standard Within-Grade Amount for each grade.  GS locality pay tables do not have standard Within-Grade Amounts.  Biweekly pay is based on the respective GS locality pay table.  You can perform this same calculation for whichever locality area you work in if you know your area’s locality pay percentage (see Schedule 9 of the President’s Executive Order) and you have access to the GS 2024 non-locality base pay table.  Note that by law GS locality pay rates are limited to the rate for Level IV of the Executive Schedule ($191,900 in 2024) so certain steps of the Grade 15 pay range may be capped at this amount.

The first two sections described the process to update the GS non-locality pay table and the various GS locality pay tables.  This section focuses on a question the Office of Human Resources often receives: “If the across-the-board general increase was 4.7 percent, and the DC area locality percentage was increased by .77 percent (DC locality was 32.49 percent in 2023 and 33.26 percent in 2024), why does the 2024 DC area GS locality pay table state ‘Total Increase: 5.31%’?  Shouldn’t the total increase be the sum of the 4.7 percent across-the-board increase and the .77 percent increase to the locality pay percentage, and therefore be 5.47 percent?”  The short answer is no, the total increase to DC area locality pay is 5.31 percent.  The answer lies in the fact that the across-the-board increase percentage is not the same as the increase to the locality pay percentage. 

Here are the calculations used to determine the total increase in locality pay:

1. Calculating the correct total percentage increase for the DC locality pay area requires taking into consideration that the DC locality pay area 2023 base is 1.3249, not 1, since the 2023 DC area locality percentage was 32.49 percent. 
2. Since the base is already greater than 1, adding 0.77 percentage point to the DC locality pay percentage (to get 1.3326) will result in a locality pay increase lower than 5.47 percent. 
3. The calculation is 1.3326 (2024 DC locality pay) multiplied by 1.047 (2023 across-the-board increase), divided by 1.3249 (2023 DC locality pay).  This equals a rounded total increase of 5.31 percent to the 2024 DC area GS locality pay.

Intuitive?  Unfortunately, not.  The same calculations can be performed to determine the total increases to any of the 2024 GS locality pay tables.
