How the ACT Score Calculator Works
The ACT uses a two-step scoring process. First, your raw score (number of correct answers) is converted to a scaled score of 1–36 using a test-specific conversion table. Then your four section scaled scores are averaged to produce the composite.
There is no penalty for wrong answers. Every correct answer adds one point to your raw score.
Step 1: Scale each section English raw (0–75) → scaled 1–36 Math raw (0–60) → scaled 1–36 Reading raw (0–40) → scaled 1–36 Science raw (0–40) → scaled 1–36
Step 2: Composite (English + Math + Reading + Science) ÷ 4 Rounded to nearest whole number
What Is Equating?
ACT adjusts raw-to-scale conversion tables for each test form to account for difficulty differences. A score of 28 means the same thing regardless of which test date you took. This process is called equating, and it ensures fair comparisons across all test dates.
Who Should Use This Calculator?
Whether you finished a practice test or just received your official results, this tool helps you understand where you stand before and after test day.
Practice test takers
Convert raw scores from official ACT practice tests to see where you stand before test day.
Students checking results
Verify your scaled scores and composite after receiving your official ACT score report.
College applicants
See which percentile your score falls in to gauge competitiveness at target schools.
Test prep tutors
Quickly convert raw scores to scaled equivalents when reviewing practice tests with students.
Parents researching options
Understand how ACT scoring works so you can set realistic goals with your student.
Students planning retakes
Identify which sections to improve to raise your composite by 1–2 points on a retake.
How to Use the Calculator
1
Count your correct answers
Go through your scored practice test or answer key. Count the number of correct answers in each section. Do not subtract for wrong or blank answers.
2
Enter each section's raw score
Type your correct-answer count into the matching field: English (max 75), Math (max 60), Reading (max 40), Science (max 40).
3
Click Calculate
The calculator converts each raw score to a 1–36 scale using representative ACT conversion tables and averages the four section scores into a composite.
4
Review your composite and sections
See your composite score, percentile rank, and individual section scores. The bar chart shows which sections are strongest.
5
Check your STEM and ELA scores
STEM averages Math and Science. ELA averages English and Reading. These supplemental scores are reported on official ACT results.
Example Score Calculation
Suppose you answered 58/75 English, 42/60 Math, 31/40 Reading, and 30/40 Science correctly.
English: 58 raw→ 28 scaled
Math: 42 raw→ 29 scaled
Reading: 31 raw→ 31 scaled
Science: 30 raw→ 30 scaled
Sum of scaled scores28 + 29 + 31 + 30 = 118
Composite (118 ÷ 4 = 29.5)→ rounds to 30
National percentile≈ 95th
Common Mistakes to Avoid
!
Subtracting for wrong answers
The ACT does not penalize wrong answers. Only correct answers count toward your raw score. Never subtract for skipped or incorrect questions.
!
Confusing raw and scaled scores
A raw score of 35 in English does not mean a scaled score of 35. Each section has its own conversion table. A 35/75 raw English score converts to roughly a 20 scaled.
!
Expecting the same conversion on every test
Conversion tables vary by test form due to equating. This calculator uses representative tables. Your official score report reflects your actual test's conversion.
!
Ignoring section score gaps
A composite of 25 could mean 25-25-25-25 or 30-20-28-22. Colleges and programs may look at individual sections, especially Math for STEM majors.
!
Overlooking how STEM scores affect programs
Most colleges use the composite score, not STEM or ELA subscores. However, some engineering programs and scholarships specifically request STEM scores.
Frequently Asked Questions
Your composite score is the average of your four section scores (English, Math, Reading, Science), rounded to the nearest whole number. Each section is scored on a 1–36 scale. The maximum composite is 36.

Pro Tip
Improving your weakest section by 4 raw questions typically raises that section score by 2 points, adding about 0.5 to your composite. Identify your biggest gap and focus prep there for the fastest composite gains.
