ASVAB Score CalculatorASVAB Line Score Calculator for Army, Marines, Navy & Air Force
Your ASVAB line scores come from your subtest standard scores: Army GT, for example, is 1.0743 × (AR + VE) − 7.44, so AR 56 and VE 55 give a GT of 112. Enter the nine subtest scores from your score sheet to get your AFQT percentile, all ten Army line scores, the four Marine Corps scores, Navy and Coast Guard composites and Air Force MAGE estimates, plus the jobs they open.
Formulas, weights and the AFQT conversion come from the Defense Manpower Data Center report Development and Evaluation of the 1997 ASVAB Score Scale hosted on officialasvab.com.

How ASVAB line scores are calculated
ASVAB line scores (composite scores) are built from your subtest standard scores, not your AFQT. Army GT, for example, is Arithmetic Reasoning plus Verbal Expression rescaled to a mean of 100, so AR 56 and VE 55 give a GT of 112. Each branch combines the nine subtests differently: the Army uses ten weighted composites, the Marine Corps four, the Navy and Coast Guard straight sums, and the Air Force and Space Force four sums reported as percentiles. Your AFQT only decides whether you can enlist; line scores decide which jobs you qualify for.
The nine ASVAB subtests
- GS – General Science
- AR – Arithmetic Reasoning
- WK – Word Knowledge
- PC – Paragraph Comprehension
- MK – Mathematics Knowledge
- EI – Electronics Information
- AS – Auto & Shop Information
- MC – Mechanical Comprehension
- AO – Assembling Objects
VE (Verbal Expression) is not a separate test. It is built from Word Knowledge and Paragraph Comprehension: VE = 0.6549×WK + 0.4056×PC − 3.0267, rounded. Standard scores have a mean of 50 and a standard deviation of 10 in the 1997 national youth sample.
Army line score formulas (official weights)
Since the 1997 score scale, the Army computes nine of its ten line scores as weighted sums of all subtests, scaled so the average American youth scores 100 (standard deviation 20). GT uses only AR and VE. These are the weights published by the Defense Manpower Data Center:
| Army line score | GS | AR | MK | MC | EI | AS | VE | Constant |
|---|---|---|---|---|---|---|---|---|
| GT (General Technical) | – | 1.0743 | – | – | – | – | 1.0743 | −7.44 |
| CL (Clerical) | – | 0.752 | 0.587 | 0.115 | 0.078 | 0.075 | 0.680 | −14.33 |
| CO (Combat) | 0.199 | 0.331 | 0.634 | 0.385 | 0.200 | 0.412 | 0.303 | −23.17 |
| EL (Electronics) | 0.083 | 0.443 | 0.491 | 0.263 | 0.303 | 0.368 | 0.499 | −22.47 |
| FA (Field Artillery) | 0.150 | 0.423 | 0.602 | 0.430 | 0.164 | 0.359 | 0.320 | −22.32 |
| GM (General Maintenance) | 0.235 | 0.464 | 0.453 | 0.293 | 0.302 | 0.505 | 0.215 | −23.36 |
| MM (Mechanical Maintenance) | 0.059 | 0.328 | 0.285 | 0.396 | 0.308 | 0.873 | 0.211 | −23.08 |
| OF (Operators & Food) | 0.143 | 0.537 | 0.341 | 0.368 | 0.197 | 0.503 | 0.368 | −22.85 |
| SC (Surveillance & Communications) | 0.012 | 0.428 | 0.636 | 0.251 | 0.322 | 0.246 | 0.528 | −21.19 |
| ST (Skilled Technical) | 0.129 | 0.490 | 0.478 | 0.312 | 0.145 | 0.217 | 0.622 | −19.65 |
Source: Segall (2004), Development and Evaluation of the 1997 ASVAB Score Scale, DMDC, Table 2.7 and equation 2.6. Many websites still show old sums such as CO = AR + CS + AS + MC; Coding Speed (CS) and Numerical Operations (NO) were dropped from the ASVAB in 2002.
Marine Corps, Navy and Air Force composites
| Marine line score | Subtests | Scaled to mean 100 | Typical jobs |
|---|---|---|---|
| GT | AR + MC + VE | 0.7553 × sum − 13.29 | Infantry (03xx) and most MOSs |
| MM | AR + MC + EI + AS | 0.5882 × sum − 17.65 | Mechanics, vehicle and aircraft maintenance |
| EL | GS + AR + MK + EI | 0.5780 × sum − 15.60 | Electronics, communications, aviation avionics |
| CL | MK + VE | 1.0923 × sum − 9.23 | Administration, supply, finance |
| Navy composite | Sum of standard scores |
|---|---|
| GT | VE + AR |
| EL | AR + MK + EI + GS |
| BEE | AR + 2×MK + GS |
| ENG | AS + MK + EI |
| MEC | AR + AS + MC |
| MEC2 | AO + AR + MC |
| NUC | VE + AR + MK + MC |
| OPS | VE + AR + MK + AO |
| HM | VE + MK + GS |
| ADM | VE + MK |
| Air Force / Space Force composite | Sum, then converted to a percentile |
|---|---|
| M (Mechanical) | AR + MC + AS + 2×VE |
| A (Administrative) | MK + VE |
| G (General) | AR + VE |
| E (Electrical) | GS + AR + MK + EI |
Air Force M, A, G and E are reported as percentiles. We convert A, G and E with the published means and standard deviations of the same sums; M is shown as a sum because its official percentile table is not published online. Navy and Coast Guard rating requirements are written directly as sums (for example VE + AR = 109).
Worked example
Subtests: AR 56, MK 32, WK 55, PC 54. VE = 0.6549×55 + 0.4056×54 − 3.0267 = 54.9 → 55. Army GT = 1.0743 × (56 + 55) − 7.44 = 111.8 → 112, enough for the GT 110 screen used for Officer Candidate School and many technical jobs. AFQT composite = 56 + 32 + 2×55 = 198, which is the 46th percentile (Category IIIB). A strong GT with a middling AFQT is common when one math subtest is weak.
How to raise your line scores
- Work on VE firstVE feeds Army GT, CL, OF, SC and ST, Marine GT and CL, Navy GT, NUC and OPS, and counts twice in the AFQT.
- Then ARArithmetic Reasoning carries real weight in every Army composite and in Marine GT and EL.
- Target the technical subtest your job needsMC and AS drive Army MM and CO; EI drives EL; GS drives ST and GM.
- Retest with a planYou can retake the ASVAB after one month, again after another month, then after six months. The newest score replaces the old one, even if it is lower.
Mistakes to avoid
Enter the standard scores from your score sheet (usually 20 to 80), not the percentile column.
Formulas that include Coding Speed or Numerical Operations come from before 2002 and will give wrong Army scores.
An AFQT of 99 does not qualify you for a job with a GT 110 minimum unless your GT is 110.
Job minimums change with recruiting needs. Treat the examples here as a guide and confirm with a recruiter or career counselor.

ASVAB line score FAQ
Enter your subtest standard scores (GS, AR, WK, PC, MK, EI, AS, MC, AO) from your score sheet. The calculator builds VE from WK and PC, then applies each branch’s formulas: Army weighted composites scaled to a mean of 100, Marine Corps rescaled sums, Navy sums and Air Force sums converted to percentiles.
100 is average. 110 is the most important threshold: it is required for Officer Candidate School, Warrant Officer programs and many technical and special-operations jobs. A GT of 120 or higher is in the top 15% or so.
GT = 1.0743 × (AR + VE) − 7.44, rounded. AR 50 and VE 50 give exactly 100; every extra point in AR or VE adds about one GT point.
No. The AFQT is a percentile (1 to 99) built from AR, MK and doubled VE, and it decides whether you can enlist. Line scores combine other subtests and decide which jobs you qualify for.
Verbal Expression, a combined score from Word Knowledge and Paragraph Comprehension (about 0.65×WK + 0.41×PC − 3.03). It counts twice in the AFQT and appears in most line scores.
No. Both subtests were removed from the ASVAB in 2002, and the Army’s current composites use weights for the nine remaining subtests. Formulas that still list CS or NO are out of date.
Four: GT (AR + MC + VE), MM (AR + MC + EI + AS), EL (GS + AR + MK + EI) and CL (MK + VE), each rescaled so the average is 100.
The Air Force and Space Force use M (Mechanical), A (Administrative), G (General) and E (Electrical) composites reported as percentiles. A job might require, for example, G 55 or E 60.
Yes. You can retest after one calendar month, again after another month, and then after six months. Your most recent score becomes your score of record, even if it is lower.
No, but it uses the official formulas and weights from the Defense Manpower Data Center’s 1997 ASVAB score scale report. Small differences of a point can occur because MEPS rounds from unrounded scores.

Last reviewed: October 30, 2026I am a pharmacist turned tech geek, and I design, code and test every calculator on DexoCalc myself. I have not served in the military, so this tool does not run on opinion: every formula, weight and conversion table in this calculator is taken from the Defense Manpower Data Center’s 1997 ASVAB score scale report, and I checked the results against worked examples before publishing.
