ACT Score Calculator
Estimate your ACT composite on the 1–36 scale from the number of questions you answered correctly in each of the four sections.
How the ACT Score Calculator works
The ACT reports each of its four sections — English, Math, Reading and Science — on a scale of 1 to 36. Your composite score is the average of those four section scores, rounded to the nearest whole number.
Like the SAT, the ACT has no penalty for wrong answers, so each section's raw score is just the number of questions answered correctly. A scale table for that test date converts the raw count to the 1–36 scale.
Formula & grading scale
- Raw to scaled — convert each section's correct count to a 1–36 scale score using that test's conversion table.
- Composite — average the four scaled scores and round to the nearest whole number.
Composite = round[(English + Math + Reading + Science) ÷ 4]
The optional Writing (essay) score is reported separately on a 2–12 scale and does not affect the composite. Scale tables differ slightly by administration, so this tool gives a representative estimate based on released tests.
Step-by-step example
- English 64/75 → scaled 31.
- Math 48/60 → scaled 30.
- Reading 34/40 → scaled 31.
- Science 30/40 → scaled 28.
- Composite = (31 + 30 + 31 + 28) ÷ 4 = 30 → estimated 30.
What is a good ACT score?
The average ACT composite is around 19–20. A score of 24 or higher is competitive at many universities, and selective schools often look for 30 and above. The best benchmark is the middle-50% range published by the colleges on your list. If you are weighing both exams, the SAT Score Calculator helps you compare an equivalent SAT total.
SAT or ACT — which should you take?
Neither test is universally easier; it comes down to which format suits you. The ACT moves faster and includes a dedicated Science section, while the digital SAT is section-adaptive. Take one official practice test of each, estimate both scores, and choose the exam where you perform better. Many students try both before deciding.
Why use our ACT Score Calculator?
It gives a quick, free estimate of your 1–36 composite so you can track progress between practice tests. Pair it with a strong academic record — check yours with the GPA Calculator — for the fullest picture of your application.
Does the ACT superscore?
Many colleges now superscore the ACT, combining your best section scores across multiple test dates into one higher composite. That means retaking the exam is usually low-risk: if you raise even a single section, your superscore can only improve. Policies differ, though — some schools use only your best single sitting — so check each college's stance before you register again. When you do retest, estimate each attempt here and keep the results so you can see which sections still have room to grow. If you also take AP exams, our APUSH Score Calculator works the same way for AP U.S. History.
Frequently asked questions
Does the ACT Writing test affect my composite?
No. The Writing (essay) score is reported on its own 2–12 scale. The composite is the average of only the English, Math, Reading and Science section scores.
Is there a penalty for guessing on the ACT?
No. There is no deduction for wrong answers, so you should answer every question even if you have to guess.
How is the composite rounded?
The average of the four sections is rounded to the nearest whole number — for example, an average of 29.5 rounds up to 30, while 29.25 rounds down to 29.
How accurate is this ACT estimate?
It uses representative conversion tables from released ACT exams. Actual curves shift slightly each test date, so use this as a study estimate rather than an official result.
What ACT score do I need for college?
The national average is about 19–20. Many universities look for 24+, and selective schools often expect 30+. Check the middle-50% ranges published by each college.
How do ACT and SAT scores compare?
Official concordance tables line the two up — for example, a 24 ACT is roughly a 1160 SAT and a 30 ACT is around a 1360 SAT. Use our SAT Score Calculator to estimate an equivalent total and decide which test suits you.
