π ACT and SAT Score Estimator
Turn practice raw scores into estimated scaled scores.
Estimated Score
How to Use This Score Estimator
Grade a practice test, count how many questions you got right in each section, and enter those raw counts here. The tool converts them to estimated scaled scores with a simplified curve and shows roughly where the result sits. It never asks for an account and it never stores your scores.
Choose SAT or ACT at the top. The input fields switch to match the test you picked.
For the SAT, enter your Reading and Writing raw score (0 to 96) and your Math raw score (0 to 58). For the ACT, enter the raw score (0 to 75) for English, Math, Reading, and Science.
Read your estimate: per-section scaled scores, plus the SAT total (400 to 1600) or the ACT composite (1 to 36).
Check the percentile band note to see roughly where the score sits nationally, then read the disclaimer: this is a practice estimate, not an official score.
Raw Scores vs Scaled Scores
Your raw score is the count of correct answers. Both tests have no guessing penalty, so a blank and a wrong answer are worth the same: zero. The scaled score is what colleges see, and it exists so scores mean the same thing across test dates. The real conversion, called equating, adjusts for each specific test form's difficulty, which is why two students with the same raw score on different dates can get slightly different scaled scores. This tool replaces the real per-form curve with a straight line from the minimum to the maximum possible scaled score. That keeps the math transparent and honest about being approximate: it is close enough for practice tracking, and never a substitute for the official score report.
Worked Example
Suppose a practice SAT gives you 70 correct in Reading and Writing and 50 correct in Math. Reading and Writing: 200 + (70 / 96) x 600 = 637.5, rounded to the nearest 10 is 640. Math: 200 + (50 / 58) x 600 = 717.2, rounded to the nearest 10 is 720. Estimated total: 640 + 720 = 1360 out of 1600. That sits in the 1200 to 1390 band, roughly the 74th to 92nd percentile nationally, meaning it beats about three quarters of test takers. The Math section (720) is the stronger of the two here, so the next study block should target Reading and Writing, where the same effort buys more points.
Raising Your Score From Here
Use the per-section breakdown, not just the total. A 100-point gap between your sections is a flashing sign: the weaker section is where each study hour earns the most. On the SAT, drill the question types you miss most and slow down on easy and medium questions, because careless errors on questions you know how to solve are the most expensive mistakes in the test. On the ACT, sections are a race against the clock, so practice with a timer until the pace feels automatic and learn when to guess and move on. Retake a full timed practice test every two to three weeks, re-enter your raw scores here, and watch the trend line. A steady climb of 30 to 50 SAT points or 1 ACT point per month of real prep is a healthy, realistic pace.
Frequently Asked Questions
How accurate is this score estimate?
It is a rough practice estimate, not a prediction of your official score. Real SAT and ACT curves are set per test form through a process called equating, and they shift a little from one test date to the next. This tool uses a straight-line approximation, so treat the result as a ballpark: usually within a few dozen SAT points or 1 to 2 ACT points of a real scaled score for the same raw performance, but not exact. Only the official test gives you an official score.
What is the difference between a raw score and a scaled score?
Your raw score is simply the number of questions you answered correctly. There is no penalty for wrong answers on either test, so your raw score is never reduced by guessing. The scaled score is the 200 to 800 (per SAT section) or 1 to 36 (per ACT section) number colleges see. Scaling exists so that a 700 means the same level of performance no matter which test date you took, even if one form was slightly harder than another.
What is superscoring?
Superscoring means a college takes your best section scores across multiple test dates and combines them into one best composite. Many colleges superscore the SAT, and a growing number superscore the ACT. If your target schools superscore, it can be worth retaking the test to lift one weak section even if your other sections are already strong, since only the best section scores count.
When should I take the official test?
Take a full timed practice test first and estimate your score here. If you are within striking distance of your target school score range, register for the next official date while the material is fresh. Most students improve meaningfully between their first and second official sittings, so plan for the possibility of two attempts: one in the spring of junior year and, if needed, one in the fall of senior year. Do not take the official test cold just to "see how it goes", since some colleges ask for all scores.
How can I raise my estimated score?
The fastest gains come from your weakest section, not your strongest. Use the per-section estimates to find it, then drill that section with timed practice and review every mistake until you can explain the right answer. For the SAT, most points are lost to time pressure and careless errors on easy and medium questions, so accuracy on the questions you attempt beats attempting everything. For the ACT, pacing is the whole game: practice each section against the clock until the timing feels routine.
