ACT Score Calculator (2026)

On the enhanced ACT the composite is the average of your English, Math and Reading scores, rounded to the nearest whole number, with a half rounding up. English 30, Math 27 and Reading 29 add up to 86, an average of 28.67, so the composite is 29. Science is optional and is reported separately.

Not on the enhanced ACT. Since the 2025 changes Science is an optional section: it gives you a Science score and a STEM score (the average of Math and Science) but it is no longer part of the composite. Older score reports used the average of all four sections, which this calculator also shows when you enter a Science score.

No. The optional Writing test is one essay in 40 minutes, scored on its own 2 to 12 scale, and ACT says taking it does not affect your subject scores or your composite. Colleges that ask for it see the Writing score next to your composite.

The conversion uses the official scoring key of one ACT practice form. Every real test form has its own table, adjusted for difficulty, so the same number of correct answers can be a point higher or lower on test day. Treat the result as a close estimate of where you stand.

Because the composite is an average of three sections, you need the three section scores to add up to three times the next composite minus 1.5. The result shows exactly how many more section points get you there, which can be a single point when you sit just under the line.

Count the questions you got right in English, Math and Reading, enter them above and the calculator converts each to the 1 to 36 scale with the official practice table. Your composite is the average of the three, rounded to the nearest whole number.

Take your best English, best Math and best Reading score across every date you tested, average the three and round to the nearest whole number (halves round up). Best 29, 26 and 31 give (29 + 26 + 31) / 3 = 28.67, a superscore of 29. ACT reports superscores itself, and many colleges use them; check each college's policy.

From 2025 the ACT is shorter, Science is optional and the composite is the average of English, Math and Reading only. A Science score and a STEM score are still reported if you take Science. This calculator defaults to the enhanced format and keeps the classic four section composite for older score reports.

Pick your composite in the "Is your ACT score good?" list on this page: every composite from 16 to 36 has its own page with its percentile, the SAT score it matches and what one more point takes. As a quick guide, ACT's national average was 19.2 for the class of 2026 and the top quarter of test takers starts at 23.

Many do. A superscore takes your best English, Math and Reading from different test dates and averages them into a new composite. Check each college's testing policy, and send the dates that give you the best section scores.

They are about equal. The official concordance tables match a 29 ACT with a 1340 SAT (the range is 1330 to 1350), so a 1350 SAT and a 29 ACT tell colleges the same thing. Send whichever sits higher in each college's middle 50% range.
