ACT Score Calculator
Estimate your composite ACT score from the raw section scores. Convert your English, Math, and Reading correct answers into a scaled 1–36 composite, add optional Science, and see your exact national percentile — instantly.
English
50 scored questions
Math
45 scored questions
Reading
36 scored questions
New for 2026: The Enhanced ACT composite is the average of English, Math, and Reading only. Each of these three now carries ~33% weight instead of 25% — so one weak section pulls harder than it used to.
Have you cleared the College Readiness Benchmarks?
ACT sets a benchmark score per section that signals a ~50% chance of earning a B (and ~75–80% chance of a C) in the matching first-year college course.
Which section moves your composite the most?
Because the composite now averages only three sections, your lowest one is your highest-return target. A 3-point gain in a single section lifts your composite by a full point.
Where your composite lands nationally

What colleges your score opens up
These tiers use published middle-50% (25th–75th percentile) admitted-student ACT ranges. Many schools are test-optional, so always check each school’s current policy.

How the ACT score calculator works
The ACT is scored in two stages. First you earn a raw score in each section — simply the number of questions you answered correctly, with no penalty for wrong answers. Then each raw score is converted to a scaled score from 1 to 36 through a process called equating, which smooths out small difficulty differences between test dates so a 28 in September means the same thing as a 28 in April. Your composite is the average of your scaled section scores, rounded to the nearest whole number (a .5 rounds up).
Enter how many questions you got right in each section above and this calculator handles the whole chain for you: raw → scaled → composite → national percentile. Because a handful of questions in every section are unscored field-test items and each form is equated separately, treat the scaled scores as close estimates — typically within about a point of an official form.
Why Math now matters more than it used to
This is the strategic heart of the new format. On the classic ACT, Math was one of four sections and contributed 25% of your composite. On the Enhanced ACT it is one of three, so it now carries roughly 33%. The same is true of English and Reading. That single change reshapes prep priorities: a low section score drags your composite down harder than before, and a strong one lifts it more. If you were historically weaker in Math than in English or Reading, closing that gap now has the highest return on your composite of anything you can do. The “section lever” panel above pinpoints exactly which section that is for you.
What is a good ACT score in 2026?
“Good” is relative to your target schools, but the national landmarks are stable and published. The average composite for recent graduating classes is about 19.2, which sits near the 57th percentile. A 21 clears the national average comfortably; a 24 reaches roughly the 80th percentile; a 27 the 88th; and a 30 the 94th percentile. A 33+ puts you in the top ~2% and into contention at the most selective universities, where the admitted middle-50% often starts at 33. The most useful move is to look up your target school’s published 25th–75th percentile band and aim at or above its 25th percentile.
| Composite | National rank | What it means |
|---|---|---|
| 33–36 | 98th–100th | Elite — competitive at the most selective universities |
| 30–32 | 94th–97th | Strong for top-50 schools & merit scholarships |
| 26–29 | 86th–92nd | Above average; competitive at many selective colleges |
| 21–25 | 68th–83rd | Solid for most state flagships and four-year colleges |
| Below 21 | Under 68th | At or below average; a focused retake pays off |
A worked example
Say a practice test gives you scaled scores of English 30, Math 24, and Reading 30. Your composite is (30 + 24 + 30) ÷ 3 = 28. Now watch what a targeted Math retake does: lift Math from 24 to 30 and your composite becomes (30 + 30 + 30) ÷ 3 = 30 — a 2-point composite jump from a single section. Under the old four-section formula, that same 6-point Math gain would have moved your composite by only 1.5 points. This is exactly why the three-section format rewards attacking your weakest area rather than spreading effort evenly.
Should you take the optional Science section?
Science no longer affects your composite, so for many students it is safe to skip — that is the appeal of the new format. But two situations argue for keeping it: some colleges and STEM programs still recommend or require it, and taking it produces a separate Science score plus a STEM score (the average of your Math and Science). A strong STEM score can strengthen an engineering or science application even when it does not touch your composite. Toggle Science on above to see both scores. When in doubt, check each target school’s current policy before test day.
Common mistakes when estimating your ACT score
The most frequent error in 2026 is averaging four sections out of habit — that inflates or deflates your composite depending on how Science compares to your other scores. The second is treating the scaled score as fixed: because of equating, the raw count needed for a given scaled score shifts by a question or two between forms, so always use the conversion table printed with your specific practice test for the tightest estimate. The third is reading the national percentile as an admissions prediction — the students competing for seats at selective colleges score well above the national pool, so pair your percentile with each school’s published range, not instead of it.

Frequently asked questions
On the Enhanced ACT, your composite is the average of your English, Math, and Reading scaled scores, rounded to the nearest whole number (a .5 rounds up). Science is optional and reported separately, so it does not count toward the composite.
Not toward your composite. On the Enhanced ACT (2025+), Science is an optional section with its own 1–36 score. If you take it, you also get a STEM score (the average of Math and Science). Some colleges and STEM programs still recommend it, so check your target schools.
It is a close estimate, typically within about a point. Because the ACT equates every test date separately, the exact raw count needed for a given scaled score shifts slightly between forms. For the tightest result, use the conversion table printed with your specific practice test.
Above the national average of about 19.2 is above average. A 24 reaches roughly the 80th percentile, a 27 the 88th, and a 30 the 94th. A 33+ is elite. The most reliable benchmark is your target school’s published 25th–75th percentile band.
No. Wrong answers and blanks both score zero, so always answer every question. Since every question now has four choices (Math dropped from five to four in the Enhanced format), a random guess gives you a 25% chance of a point.
It varies by form because of equating, but on many recent tests you can miss only a couple of questions per section and still reach a 36. Math tends to be the least forgiving at the top — often just 1–3 misses allowed — while English and Reading sometimes permit slightly more.
Roughly 19.2 for the composite, based on ACT’s official national ranks for graduating classes of 2023–2025. Section means are about English 18.6, Math 19.0, Reading 20.1, and Science 19.6. Any composite above 20 puts you above the national average.
Superscoring combines your highest section scores across multiple test dates into a new, higher composite. Many colleges accept ACT superscores, and ACT sends one automatically. This makes retaking and targeting one weak section at a time a smart strategy — but confirm each school’s policy first.
Colleges accept both equally. The ACT is faster-paced with an optional Science section; the SAT is adaptive and gives more time per question. Estimate both, convert between them, and submit whichever ranks higher — our SAT to ACT converter handles the comparison.
No. The Writing essay is scored separately on a 2–12 scale and never counts toward your 1–36 composite. A few colleges still require or recommend it, so check requirements before you register.
Methodology & disclaimer. Scaled-score estimates are modeled on recently released Enhanced ACT practice forms; percentile ranks are taken from the official ACT National Ranks table for the 2025–2026 reporting year (graduating classes of 2023–2025). Because each test date is equated separately, treat results as planning estimates (typically within ~1 point), not official scores. For official reports, use your MyACT account.
