ACT Score Calculator

Getting your composite takes less than a minute. The tool averages your four scaled section scores and rounds the result the way the ACT does.

1. Enter your English, Math, Reading and Science scores in the four fields. Each score runs from 1 to 36.
2. If you took the Enhanced ACT without Science, tick the box under the fields and leave Science out.
3. Press Calculate to see your composite score, the exact average, the total of your section scores, and your strongest and weakest sections.
4. Press Reset to clear the form and start over with new scores.

Composite = (English + Math + Reading + Science) divided by 4, rounded to the nearest whole number. English is your English section score, Math is your Math section score, Reading is your Reading section score, and Science is your Science section score. Each section score is a scaled score from 1 to 36, so the composite also runs from 1 to 36.

An average that ends in exactly .5 rounds up, never down. An average of 25.5 becomes a composite of 26. The optional Writing section is scored separately and never counts toward the composite.

The Enhanced ACT, which became the standard format in the 2025 to 2026 testing year, made Science optional. On the Enhanced ACT the official composite is the average of English, Math and Reading only.

Take a student who scored 30 in English, 28 in Math, 32 in Reading and 26 in Science. Add the four scores first. 30 + 28 + 32 + 26 = 116. Divide by 4 to get the average. 116 divided by 4 = 29.0. The average is already a whole number, so no rounding is needed and the composite score is 29.

Try a case that needs rounding. Scores of 25, 24, 26 and 27 add to 102. 102 divided by 4 = 25.5. Because the average ends in .5, it rounds up, and the composite is 26.

Your composite is an average, not a total. Two students can share a composite of 29 with very different section scores, so colleges also read the four section scores beside it.

There is no single score that counts as good for every student, because every college sets its own bar. Compare your composite with the middle range of scores a college publishes for admitted students. If your composite sits inside that range, your score is competitive there.

Your composite sits beside other test results in an application. The SAT score calculator works the same way for the SAT, and the GPA calculator turns your school grades into a grade point average.

The most common mistake is adding raw counts of correct answers instead of scaled section scores. The composite is built from the scaled scores of 1 to 36 on your score report, not from the number of questions you answered correctly.

• Rounding .5 down instead of up, which gives a composite one point too low.
• Adding the Writing score into the average, which the ACT never does.
• Averaging only three sections on a classic four section report, or four sections on an Enhanced report taken without Science.
• Treating the composite as a total out of 144. It is an average out of 36.

Before the redesign, every student took all four sections and the composite was always the average of four scores. The Enhanced ACT kept English, Math and Reading as the core sections and made Science optional at registration. Students who skip Science still get a composite, built from the three sections they took, and Science is reported on its own when taken.
