Enter the four standard scores from your ASVAB score sheet to get your AFQT percentile, your AFQT category and published branch thresholds. Use standard scores, not practice percentages or numbers of correct answers. Your official report remains the record of your result.

The Space Force diploma reference is the department baseline of 36; component policy permits an otherwise-qualified Tier One applicant at 31. Read the branch notes and official sources before interpreting any comparison.
Clearing the floor is not the same as getting the job you want. Services consider the AFQT alongside education and other eligibility requirements. Job qualifications also depend on line scores and role-specific requirements. Work those out with the line score calculator.
How the calculation works
Four subtests produce the AFQT. Two of them enter directly; the other two are first combined into Verbal Expression, which is then doubled. Both vocabulary and reading comprehension matter. Use missed practice questions to decide which skill to study next; a formula weight alone does not tell you where you can make the most progress.

Why standard scores and not raw answers
Every input here is a standard score — a scaled number with a mean of 50, printed on your score sheet next to each subtest. It is not the number of questions you answered correctly, and a practice number-correct total cannot substitute for it. On the computer version of the ASVAB the questions adapt to your performance, and scoring uses item response theory precisely so that a score means the same thing regardless of which items you happened to see. There is no fixed number-correct table that reproduces that process for an arbitrary practice test.
If you need to strengthen an AFQT subject, start with a worked math lesson, vocabulary session, or reading skill. If your goal is a particular job, check its required line scores before deciding which subjects deserve more time.

Frequently Asked Questions
AFQT = AR + MK + 2 × VE, where AR is Arithmetic Reasoning, MK is Mathematics Knowledge and VE is the Verbal Expression composite built from Word Knowledge and Paragraph Comprehension. All of these are standard scores, not raw numbers of correct answers. The resulting composite is then converted to a percentile from 1 to 99 using a Department of Defense table.
A count of correct practice answers is not a standard score. The computer version of the ASVAB is adaptive: the questions you see depend on how you answered earlier ones, and scoring uses item response theory so that scores mean the same thing regardless of which items you were given. A fixed number-correct table cannot reproduce that adaptive scoring. Your standard scores are printed on your score sheet.
No. That was the definition on the 1980 score scale. On the current score scale, which was built from 1997 norming data and has been in use since 2004, Verbal Expression is an optimally weighted composite in which Paragraph Comprehension carries about 0.62 the weight of Word Knowledge, restandardized to a mean of 50. This calculator uses the current definition.
It is the percentage of a reference group scoring at or below you. The reference group is fixed: PAY97 — Profile of American Youth, 1997 (ages 18–23). So an AFQT of 60 means you scored as well as or better than 60% of that group — not 60% of the people who took the test with you, and not 60% of questions correct.
Set every slider to 50 — the mean of the standard score scale — and the AFQT comes out at 48, not 50. The composite distribution in the reference sample is not symmetric, so the mean profile does not land on the median percentile. It is a small effect but a real one, and it is in the official conversion table.
The branch table compares your percentile with sourced reference thresholds, with service sources reviewed on 2026-10-13. Unknown values are marked for recruiter confirmation. Education classification, component exceptions and other requirements still matter. Job qualifications use additional composites; this comparison does not determine eligibility.
