ACT Score Calculator

Where the numbers come from

Each score this calculator shows comes directly from ACT's own papers. We don't guess anything from forum posts, and we never average old tests together. Since we write for students reading on a phone, the lines stay short, and we call out exceptions rather than bending the rule.

The ACT documents we use

  1. Correct answers on the newer test are converted into scores ranging from 1 to 36 using the chart in the Enhanced ACT scoring guide (document JA04037.CJ20252). Only scored questions count, and the limits are up to 40 for English, 41 for Math, 27 for Reading and 34 for Science.
  2. For the older test, Form 2176CPRE, the chart appears in Preparing for the ACT 2024–2025. For each score, ACT prints a range of right answers, and the calculator reads those ranges exactly as printed.
  3. The composite rounding rule is set by Understanding Your ACT Scores. You average the section scores first. Anything less than a half rounds down, while a half or more is rounded up.
  4. ACT National Ranks for 2026–27 is the source for every percentile. For every score, it shows the share of recent graduates who landed at or below it. There is a separate rank for STEM, the score you get by averaging Math and Science and rounding.
  5. The superscore is explained in ACT's superscore FAQs. Sum the best scores you earned in English, Math and Reading, divide by 3, then round the same way.

Each test form gets a small adjustment to the chart from ACT. That means on an actual test day, a section score may come in about a point above or below the estimate here.

When we take another look

ACT releases new national ranks once a year. Every September we compare the ranks and both charts with ACT's site, and we look again whenever ACT puts out a new free practice test. Because each chart is built into the page itself, the calculator never has to wait on another server.

Every change gets tested first

Before any update goes live, test cases cover a perfect score, a zero, and the lines for Science and STEM. One case handles the half-point rule on the older test, where 27.5 rounds to 28. We also match each chart line by line with copies pulled from ACT's documents.
