ACT Score Calculator
Enhanced ACT (2025) raw → scaled composite (1–36), optional Science and SAT equivalent — estimate. Accurate, instant and free — for United States.
What these mean:
Composite ≈ 26 — the rounded mean of 3 section scores · about SAT 1200 (approx. concordance)
English
26
Math
26
Reading
26
Science (not counted)
21
Composite (est.)
26
SAT equivalent (approx.)
≈ 1200
Your composite is the rounded mean of 3 section scores — an estimated 26 out of 36, roughly equivalent to an SAT total near 1200.
This is an estimate, not an official score
Optional Science changes the composite live
SAT ↔ ACT concordance is official but approximate

How raw scores become an ACT composite
The ACT has up to four sections — English (75 questions), Math (60), Reading (40), and Science (40). Your number correct in each is scaled onto 1–36, and the composite is the rounded mean of the sections that count. Because each form is scaled separately, we show a representative estimate, not one false-precise number.
Raw → section scaled
correct count → 1–36
section = scale(raw correct) → 1–36
No wrong-answer penalty — only correct answers count. Each section runs 1–36.
Composite = rounded mean
3 sections (Enhanced) or 4 (legacy)
composite = round(mean of section scores)
Enhanced ACT (2025) averages 3 sections; legacy averages 4 (adds Science).
- 1Section scaled scores: 60 correct in English maps to about 26, 48 in Math to 26, and 32 in Reading to 26.
- 2Composite: The rounded mean of the three counting sections, round((26 + 26 + 26) / 3) = 26 — roughly an SAT total near 1200 on the concordance.
Why it's an estimate — and what Science does
No calculator can print your exact ACT composite. The test is scaled per form, so treat every figure here as a planning estimate, not a promise.
No single official conversion exists
Enhanced ACT (2025) makes Science optional

Frequently asked questions
Each section — English (75 questions), Math (60), Reading (40), and Science (40) — is scored on your number of correct answers, with no penalty for wrong answers. That raw count is converted onto the 1–36 scale for your specific test form. The composite is simply the rounded average (mean) of your section scaled scores: on the Enhanced ACT (2025) that is the mean of English, Math and Reading (Science is optional), while the legacy test averaged all four. Because each form is scaled separately, this calculator shows a representative estimate, not one exact number.
It depends on the version. On the Enhanced ACT introduced in 2025, Science is an optional section and the core composite is the rounded mean of only English, Math and Reading (three sections). On the legacy ACT, Science counted and the composite averaged all four sections. This calculator lets you toggle Science on or off so you can see the composite under either rule — the denominator changes from 3 to 4 and your composite updates live.
ACT scales each test form separately so that a given scaled score reflects the same ability regardless of which date or form you took. That means the same number of correct answers can map to a slightly different scaled score across forms, so no single fixed conversion table exists. The honest answer is an estimate — your official composite may differ by a point or two.
The College Board and ACT publish a joint concordance that maps the ACT 1–36 scale to the SAT 400–1600 scale. As rough anchors, an ACT 19 is about a 1000 SAT, a 25 is about a 1200, a 28 is about a 1300, a 31 is about a 1400, and a 34 is about a 1500. This calculator shows the approximate SAT equivalent for your composite, but the concordance is a band mapping, not an exact equivalence — use it as a guide.
It depends on the colleges you are targeting. As a rough national guide, the average composite is around 19–20, a 24 puts you near the top quarter of test-takers, a 28 near the top 10%, and a 33+ near the top few percent. Always compare against the published middle-50% ACT range of admitted students at your specific schools rather than a single national benchmark.

Method, assumptions & references
Methodology: each section (English 75q, Math 60q, Reading 40q, Science 40q) is scored on correct answers with no wrong-answer penalty, then scaled onto 1–36; the composite is the rounded mean of the counting sections — three (English, Math, Reading) on the Enhanced ACT (2025), or four including Science on the legacy test. The SAT equivalent uses the joint ACT/College Board concordance band. Scores here are representative estimates because ACT scales every form separately — there is no fixed public table. All calculations run client-side; nothing is stored. Reference data as of 2025.

How we calculate this
Reviewed by Reckonist Editorial · Last reviewed 4 July 2026. Figures follow the methods and sources set out in our editorial standards.
ACT scoring is scaled per test form, so no calculator can output an official composite. The scores shown are representative estimates for planning only, not a guaranteed or official result, and the SAT equivalent is an approximate concordance band. Always confirm score requirements against each college's official admissions pages and your official ACT score report.
