Free ACT score calculator.
Drag the sliders to set how many you got right per section. Each raw count scales to a 1–36 — the composite is the average across English, Math, and Reading. Science is optional.

How ACT scoring actually works.
Raw → scaled, not percentage.
You don't get a percentage out of how many you answered correctly. Every section's raw count maps to a 1–36 scaled score using ACT's curve. Miss a couple on English (50 questions), you might still land at 33. Miss a couple on Reading (36 questions), the drop is steeper because there's less room to absorb errors.
Composite is just the average.
Add your four scaled scores — English + Math + Reading + Science — and divide by four. Round to the nearest whole number. That's it. A 34 + 32 + 30 + 32 averages to 32. No weighting, no secret formula. The composite is what colleges look at first.
Science is optional now (2026 ACT).
Starting with the 2025–26 test year, Science became optional on the ACT. Most selective colleges still want it. If you skip Science, your composite is just E + M + R divided by three. If you take it, it's included. The calculator above lets you toggle either.
Percentile tells you your rank.
A 30 sits above roughly 93% of test-takers. A 24 is around the 74th percentile — solidly above average. A 36 is the 99th+ (about 0.3% of testers nationally). Percentiles drift year-over-year, but the brackets stay close enough that the number above is a reasonable read of where you stand.

What counts as a good score?
The national average ACT composite is around 19.5. That number drifts a point or two each year as the test-taking pool shifts, but it's a useful anchor: half of every cohort scores below it.
For most flagship state universities, a 22 to 25 lands you in the meaty middle of the admitted range. You won't stand out on score alone, but you also won't be filtered out before anyone reads your essay.
Selective private schools and out-of-state publics usually cluster around 28 to 30. This is where score becomes a real differentiator — small movements (a 28 to a 31) can change the school list more than any other factor in your application.
Ivies, top-20s, and the most selective programs cluster at 33 to 36. At this tier, score is necessary but never sufficient — it gets you read, nothing more.
The honest version: a "good" ACT score is whatever opens the doors of the specific schools you want. Look up your target schools' published middle-50% range, aim for the upper end of it, and stop optimizing past that.

What this won't promise you.
This calculator is a projection from one set of raw counts. It is not a diagnostic. If you've never sat a full timed test under real conditions, your real-day score will land somewhere on a wider band than the dial suggests.
Real ACTs vary. Even strong, consistent test-takers swing two or three points across sittings, sometimes for reasons that have nothing to do with prep — sleep, caffeine, which proctor you got, whether the room was 64°F or 78°F.
Percentiles drift. ACT publishes new percentile tables every year. A 30 today may sit a percentile or two off where a 30 sat five years ago. The brackets above are accurate at time of writing.
The number on the dial is a useful target, not a verdict. What changes scores is what you do between now and the test — which questions you miss, which patterns you fix, which weak sections you actually drill instead of avoid.
Practice the sections you're soft in.
Actify drills the exact subscores the calculator just told you were weakest. Free, no credit card, all four sections.
