ASVAB AFQT Calculator
Your AFQT decides whether you can enlist. It comes from four ASVAB subtests: Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning and Mathematics Knowledge. Enter your standard scores for an exact percentile, or your practice-test percent correct for an estimated range, and see which branch minimums you clear.
Enter the subtest standard scores from your ASVAB score report (about 20-80; the average is 50). The result uses the official conversion table, so it is exact.

How the AFQT is calculated
Every ASVAB subtest is reported as a standard score with an average of 50 and a standard deviation of 10. About half of the reference group scores 50 or higher and about 16% score 60 or higher.
Step 1: Verbal Expression (VE). Word Knowledge and Paragraph Comprehension are combined into VE. It is a weighted blend, not a plain sum: Paragraph Comprehension counts about 0.62 as much as Word Knowledge, and the result is put back on the 50/10 scale.
Step 2: AFQT raw score = AR + MK + 2 × VE. Verbal skills count twice, which is why Word Knowledge and Paragraph Comprehension practice pays off so much.
Step 3: convert to a percentile. The raw score is looked up in the official 1997-scale conversion table (Defense Manpower Data Center, 2004). The AFQT runs from 1 to 99.
Example: WK 55, PC 52, AR 48 and MK 50 give VE 54, a raw score of 48 + 50 + 2 × 54 = 206, and an AFQT of 54 (Category IIIA).
| AFQT raw score (AR + MK + 2·VE) | AFQT percentile |
|---|---|
| 160 | 14 |
| 183 | 31 |
| 200 (every subtest at 50) | 48 |
| 202 | 50 |
| 215 | 64 |
| 230 | 79 |
| 249 | 93 |
| 260 | 97 |
AFQT categories
| Category | AFQT percentile |
|---|---|
| I | 93–99 |
| II | 65–92 |
| IIIA | 50–64 |
| IIIB | 31–49 |
| IVA | 21–30 |
| IVB | 16–20 |
| IVC | 10–15 |
| V | 1–9 |
Category V is not eligible to enlist. Federal law limits Category IV recruits (AFQT 10–30) to 4% of a service's enlistees in a year (the Secretary of Defense can raise that to 20%). Services group the IV range in their own ways.
Minimum AFQT by branch
- Army: 31 with a high school diploma. GED minimum not stated on goarmy.com. Applicants scoring 21-30 may qualify for the Future Soldier Prep Course (academic track).
- Navy: 31 with a high school diploma. No GED number published on the Navy recruiting site. The Navy Recruiting Manual requires 50 or higher for applicants without a Tier 1 or Tier 2 education credential.
- Air Force: 31 with a high school diploma; 50 with a GED. Both values published on airforce.com.
- Marine Corps: 31 with a high school diploma. No GED number published; GED applicants get further recruiter review.
- Coast Guard: 32 with a high school diploma. GED applicants also need Coast Guard Accessions approval; no official GED number is published.
- Space Force: no AFQT number published. No AFQT number published ("a qualifying ASVAB score"); jobs list Air Force composite minimums.
Published figures as of October 25, 2026. Minimums change with recruiting needs: confirm with a recruiter.
Frequently asked questions
- How is the AFQT score calculated?
- The AFQT uses four of the ten ASVAB subtests. Word Knowledge and Paragraph Comprehension are blended into a Verbal Expression (VE) score, with Word Knowledge weighted more heavily. Your AFQT raw score is Arithmetic Reasoning + Mathematics Knowledge + 2 × VE, all as standard scores, and that sum is converted to a percentile from 1 to 99 using the official 1997-scale conversion table.
- Is the AFQT the percent of questions I got right?
- No. The AFQT is a percentile: it compares you with a national sample of about 6,000 people aged 18 to 23 who took the ASVAB in 1997 (the norms used since 2004). An AFQT of 50 means you scored as well as or better than 50% of that group.
- What AFQT score do I need to join the military?
- As of October 25, 2026, the published minimum with a high school diploma is Army 31, Navy 31, Air Force 31, Marine Corps 31, Coast Guard 32. The Air Force publishes 50 for GED holders, and the Space Force does not publish a number. Minimums change often, so confirm with a recruiter.
- What are the AFQT categories?
- Category I is 93-99, II is 65-92, IIIA is 50-64, IIIB is 31-49, IVA is 21-30, IVB is 16-20, IVC is 10-15, V is 1-9. Category V is not eligible to enlist, and federal law limits how many Category IV recruits each service can take in a year.
- Can I turn practice-test percent correct into an exact AFQT?
- Not exactly. The CAT-ASVAB is adaptive: your standard score depends on which questions you answered correctly, not just how many, and no public table converts a number right into a standard score. That is why the practice mode on this page shows an estimated range. Scores from a real ASVAB score report give an exact result.
- What are line scores?
- Line scores (composites) are other combinations of subtests that each service uses to decide which jobs you qualify for. For example, the Army GT score is AR + VE, the Marine Corps GT adds Mechanical Comprehension, and the Air Force reports Mechanical, Administrative, General and Electronics (MAGE) percentiles.
About the ASVAB exam
The Armed Services Vocational Aptitude Battery (ASVAB) is the test every U.S. military applicant takes, and roughly a million people a year sit for it, including high school students in the Career Exploration Program. At a Military Entrance Processing Station it is given as the CAT-ASVAB, a computer-adaptive test of ten subtests: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Auto Information, Shop Information, Mechanical Comprehension and Assembling Objects. The test adapts as you go: a correct answer usually leads to a harder question and a miss to an easier one, and you cannot go back to a question once you have answered it. Four subtests matter most. Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension make up the Armed Forces Qualification Test (AFQT), the percentile score that decides whether you can enlist; verbal skills count twice in it. The other subtests feed the line scores (composites) each service uses to match you to jobs, such as the Army GT score or the Air Force Mechanical, Administrative, General and Electronics scores. No calculator is allowed, which is where many test-takers lose points: fractions, percents, rates and basic algebra all have to be done by hand. Others struggle with vocabulary they have not seen since school, or with the technical subtests if they have never worked on engines, circuits or tools. Strong preparation starts with the AFQT four, builds hand-calculation speed and vocabulary, then targets the technical subtests that matter for the jobs you want.
Exam structure
CAT-ASVAB: 10 subtests and 135 scored questions in this order: General Science (15 questions, 12 min), Arithmetic Reasoning (15, 55 min), Word Knowledge (15, 9 min), Paragraph Comprehension (10, 27 min), Mathematics Knowledge (15, 31 min), Electronics Information (15, 10 min), Auto Information (10, 7 min), Shop Information (10, 6 min), Mechanical Comprehension (15, 22 min) and Assembling Objects (15, 18 min). Most people finish in about 2 hours. Some questions are unscored tryout items, and every question has four answer choices.
Scoring
Each subtest gets a standard score (average 50, SD 10). The AFQT percentile (1-99) comes from AR + MK + 2 x VE, where VE is a weighted blend of WK and PC, converted with the official 1997-scale table; the published minimum for most branches is 31 with a high school diploma. Services also compute job line scores from other subtest combinations.
Common mistakes
- Leaning on a calculator in practice: none is allowed on the ASVAB, so fraction, percent and rate arithmetic must be fast by hand.
- Guessing wildly when time runs short on the CAT-ASVAB, which penalizes a string of wrong answers late in a subtest; keep reading and answering for real.
- Treating the AFQT as percent correct: it is a percentile compared with a national sample of 18- to 23-year-olds.
- Ignoring Word Knowledge and Paragraph Comprehension, even though verbal skills count twice in the AFQT.
- Skipping the technical subtests entirely when the jobs you want depend on line scores such as mechanical or electronics composites.
