ACT Score Calculator 2026: Estimate Your Composite and Percentile
This free ACT score calculator turns the number of questions you got right in English, Math, and Reading into an estimated scale score for each section, a composite, and a national percentile. Since 2025, the ACT composite averages those three sections only. Science is optional and reported separately.

The Digital SAT produces scores on a 400–1600 scale by combining two section scores: Reading and Writing (200–800) and Math (200–800). Your raw score in each section, which is the total number of questions you answered correctly, converts to a scaled score through a process called equating. The College Board adjusts this curve for each test administration so that a 700 in one sitting represents the same ability as a 700 in another, even if the two tests differed in difficulty.
There is no penalty for wrong answers on the Digital SAT. Your raw score is simply your correct-answer count, which means a blank response is always worse than a guess. On a four-choice question, a random guess gives you a 25% chance of earning a point. Blank answers guarantee zero.
The total number of questions is 98: 54 in Reading and Writing across two modules, and 44 in Math across two modules. Every question carries equal weight within its section.

Yes, you can use a calculator on the Digital SAT. The College Board integrated the Desmos graphing calculator directly into the Bluebook testing app for all Math questions, including Module 1. There is no longer a no-calculator section on the Digital SAT as of the 2024 rollout. Students may also bring their own approved handheld calculator, such as a TI-84 Plus, as a backup device. The built-in Desmos graphing calculator on the Digital SAT handles graphing, equation solving, statistical regressions, and unit conversions. It does not solve word problems for you, and it will not tell you which formula to apply. The tool is most valuable when used deliberately on high-complexity geometry, function transformation, and data analysis questions.
For the complete approved calculator list, see the College Board calculator policy. For a one-page Desmos reference you can review before test day, download our free SAT Desmos cheat sheet.
The best place to practice using Desmos under real test conditions is the College Board's free Bluebook app, which uses the same adaptive format and the same built-in calculator as the actual exam. We walk students through Desmos fluency as part of our one-on-one SAT tutoring before they take a practice test.
Your SAT percentile tells you the percentage of test-takers who scored at or below your composite. The national average composite for the class of 2024 was approximately 1050, placing at the 49th percentile. A composite of 1300 reaches the 86th percentile. A 1500 places you at the 98th percentile, which is the range most competitive for Ivy League and top-20 university admissions.
Percentile rankings matter for college applications because admissions offices evaluate your score against the school's current student body, not the national average. A 1400, while strong nationally (94th percentile), may sit below the 25th percentile at a highly selective school.
To understand how your percentile translates to real admissions outcomes, our breakdown of Ivy League SAT score requirements maps specific composites to the 25th and 75th percentile ranges at Harvard, Yale, Princeton, MIT, Columbia, and the other six Ivy League schools.
A good SAT score is the score your target schools want to see, not a fixed number. The national average SAT score is 1050 (class of 2024). Statistically, any score above 1200 is above average. But for college admissions purposes, the relevant benchmark is always your target school's middle 50% SAT range, specifically its 25th and 75th percentile scores.
To be competitive, you want your score at or above the school's 25th percentile. Scoring above the 75th percentile makes your application significantly stronger. Scoring below the 25th percentile doesn't disqualify you, but it means other parts of your application need to compensate.

A score alone doesn't determine admission. Our article on what Ivy League admissions really weighs explains how test scores interact with GPA, essays, and extracurriculars in selective admissions decisions.
Your score today is a data point, not a verdict. The most important thing to know is exactly how far you are from your target school's 25th percentile SAT range, because that gap tells you how much work is actually required.
Most students overestimate how hard it is to close a 100-point gap. With structured one-on-one prep, 92% of NAT students improve by 90 or more SAT points. Many students reach their target composite in 8–12 weeks when prep focuses on their actual error patterns rather than generic test strategies.
Here is a practical three-step approach:
Find your gap. Use the university match panel above to see where your score sits against your target schools' 25th percentile ranges. If you're within 100 points of a school's 25th percentile, you're in the improvable zone.
Diagnose before you drill. Doing more practice tests without knowing why you're missing questions doesn't close the gap. A diagnostic session with an NAT tutor identifies whether your score loss is content-based (gaps in specific topics) or process-based (pacing, careless errors, question misreads).
Build a targeted plan. A free SAT score review with a NAT tutor gives you a specific breakdown of which topics and question types are costing you the most points, and a prep plan that addresses those first.
If you've taken both the SAT and ACT and aren't sure which test gives you the stronger result, our ACT to SAT score conversion chart helps you compare directly. Some students score materially higher on one test than the other, and knowing which to submit can change your application profile.
NAT tutors have been where your student is. Every tutor scored in the 99th percentile on their own test and graduated from a top-15 university. Tutors, including Alexander (1600 SAT, Brown University School of Medicine), Wanning (1570 SAT, 800 Math, Stanford PhD candidate), Gia (1570 SAT, Cornell), Rachel (1580 SAT, UCLA), and Uju (1590 SAT, 35 ACT, Northwestern), bring session-specific, pattern-based tutoring that goes beyond what any prep book or algorithm can offer.
The approach NAT uses is the sinking-ship method: identify exactly which question types and skill areas are pulling the score down, fix them systematically, and confirm the fix with practice data before test day. There are no long-term contracts and no group sessions. Every session is one-on-one, built around the student's specific score gaps and test timeline.
If your score is not where it needs to be for your target schools, schedule your free consultation and find out exactly what it would take to reach your target.

FAQ’s
Frequently Asked Questions
How is the ACT composite score calculated?
The ACT composite is the average of your English, Math, and Reading scale scores, rounded to the nearest whole number. A fraction of one-half or more rounds up. Science is optional and no longer counts toward the composite, and the Writing test is reported separately on a 2 to 12 scale. For example, section scores of 28, 24, and 31 average 27.67, which rounds to a composite of 28.
Does Science count toward the ACT composite?
No. ACT began phasing Science out of the composite for national online testing in April 2025, and by September 2025 every test mode used the updated calculation. Science is still scored from 1 to 36 and reported separately when a student takes it. Check each target school's policy before deciding whether to take the section.
How accurate is this ACT score calculator?
This calculator gives an estimate, not an official score. ACT converts raw scores to scale scores so results mean the same across all test forms, which means the same number of correct answers can land slightly apart on different test dates. Use the estimate to see where you stand, then confirm with a full timed practice test or your official score report.
What is a good ACT score?
A good ACT score is one that reaches the middle range of admitted students at your target schools. ACT reported a national average composite of 19.4 for 2024. Compare your composite with the middle 50% range for each school on your list, which the college tiers table on this page summarizes by school type, and aim for the middle of that range or higher.
Can you use a calculator on the ACT?
Yes, but only on the Math test. Calculators are not allowed on English, Reading, or Science, and every Math problem can be solved without one. Online test takers use the Desmos graphing calculator built into the testing platform. Paper test takers must bring a permitted calculator, because test staff do not supply one, and models such as those with computer algebra systems are prohibited.
Does the ACT have Desmos?
Yes, the online ACT includes the Desmos graphing calculator inside the testing platform during the Math section. Students testing on paper do not use Desmos and must bring a permitted calculator. ACT's policy page does not say whether a personal calculator may be used alongside Desmos on the online test, so check ACT's current calculator policy before test day.
What is ACT superscoring?
An ACT superscore is the average of your highest English, Math, and Reading scores across all of your test dates. Since 2025, Science is no longer part of the superscore calculation. Only your best score in each section counts toward it, so a retake cannot lower it. Not every college accepts superscores, so check each target school's policy.
How many times can you take the ACT?
There is no limit to how many times a student can take the ACT, according to ACT. ACT also reports that students take the test two to three times on average to reach their goals, and that students who first scored between 13 and 29 raise their composite by an average of one point when they retest. Plan retakes around real test dates and your target schools' deadlines.
