ACT score calculator
Type how many questions you answered correctly in each section. The tool looks that raw score up on an official ACT released form, converts it to a section scale score, then averages the sections that count and rounds. Every result here is labelled UNOFFICIAL, and the form the numbers came from is named next to the estimate.
Worth checking if you have used an older ACT calculator. On the enhanced ACT the science and writing sections are optional and do not affect the Composite score, so a four-section average will not match what ACT reports. This tool averages three.
Estimate your Composite from raw scores
Enter your number correct for English, Mathematics, and Reading, then press the button. Leave a box blank and that section shows estimate unavailable rather than a guess.
Work backwards from a target Composite
Pick the Composite you are aiming for. The tool inverts the same tables and returns the smallest number correct in English, Mathematics, and Reading that lands there on this form. If your target cannot be built from the form's tables, you get "not reachable on this form" instead of a made-up cutoff.
What changed on the Enhanced ACT
Most calculators still ranking for this term average four scale scores. That is the old test. On the enhanced ACT the science and writing sections are optional and do not affect the Composite score, and your Composite score is the average of your English, math, and reading scores, rounded to the nearest whole number. Science is still reported on the same scale, and you will still see it here, but it sits outside the Composite.
The rounding is not a mystery either. Fractions less than one-half are rounded down, and fractions of one-half or more are rounded up. So the tool shows you the unrounded three-section average next to the rounded Composite. If your average sits just under a half, you can see exactly how close you are to tipping into the next whole number, and the per-section hint tells you how many more questions correct would buy you one more scale point in each section.
ACT section scores and the ACT Composite score are reported on a 1 to 36 scale, which has not changed.
Where these numbers come from
The conversion tables in this page are transcribed from the official ACT National Online Practice Test 1 Scoring Key and Conversion Tables published by act.org. The percentile figures come from the official ACT Score National Ranks for 2025 and 2026. Nothing on this page is remembered or estimated by a language model. Every scale score, every average, and every percentile you see is looked up or recomputed in your browser from those two files, which is why the tables are printed in full below rather than hidden behind the button.
I built these estimators from the ground up, and I transcribe each curve straight from the test maker's released-exam PDF and version-stamp it with the exam and the year before it ever reaches a page. I also wrote the "estimate unavailable" state on purpose. When a raw score falls outside the vetted table, or the curve for an exam and year has not been loaded, the tool refuses to print a cutoff. A blank is honest. A guessed cutoff would look identical to a real one and be worthless to you.

Common questions
Does science count toward the Composite
No. On the enhanced ACT the science and writing sections are optional and do not affect the Composite score. Enter your science raw score anyway if you have it. The tool converts it, shows its scale score and its national rank, and marks it as not in the Composite, so you can report it accurately without it skewing the average.
What a national rank tells you
An ACT national rank indicates the percentage of students who scored at or below a given score. The current ACT national ranks are based on ACT-tested high school graduates of 2023, 2024, and 2025, and they are used for ACT tests taken from September 2025 through August 2026. Ranks are official ACT data, unlike your estimated score, which is not.
Why your estimate is unofficial
Your scale scores here come from one published conversion curve for one released form. Real test days use their own form and their own curve, and the same number correct can convert differently. Use this to see where your points are and where they are cheapest to gain, not to predict a score report.
Can a score estimate tell you where you will get in
No, and be careful with any tool that suggests otherwise. A score estimate does not guarantee admission, credit, placement, or any outcome. Colleges set their own policies and read far more than one number.
When the tool says estimate unavailable
You will see that phrase when the raw score you typed is not in the vetted table for that section, or when a section is blank. The Composite needs all three of English, Mathematics, and Reading, so a single missing section leaves the Composite unavailable too. That is the tool working correctly, not breaking.
The fine print
- Every estimate here is UNOFFICIAL. Only the College Board or ACT can give you an official score.
- This estimate uses a published score-conversion curve from a specific exam and year, shown with each result; official curves change about once a year, so your real test may scale differently.
- ExamScoreCalc is not affiliated with, endorsed by, or connected to the College Board or ACT, and a score estimate does not guarantee admission, credit, placement, or any outcome.
