About the SAT & ACT Superscore Calculator
This superscore calculator takes your section scores from up to four SAT or ACT sittings, keeps the highest score in each section and rebuilds the total the way colleges that superscore do. For the SAT that means best Reading and Writing plus best Math (400–1600); for the ACT it averages your best English, Math and Reading — plus Science on the legacy test — and rounds halves up to a 1–36 composite.
It is for students deciding whether another test date is worth it, and for families comparing how a student looks at superscoring colleges versus schools that consider only a single sitting. The results show your best single-sitting score next to the superscore, so you can see exactly how much superscoring adds.
Superscoring policies vary: many colleges superscore the SAT, fewer superscore the ACT, and some require you to send every score. On the enhanced ACT introduced in 2025, the composite uses English, Math and Reading only, with Science reported separately; choose the legacy format for older tests where Science counts. Check each college’s testing policy before relying on a superscore.
With the default inputs, the superscore is 1,330. Change any value above to recalculate instantly.
How to use the sat & act superscore calculator
- 1Choose SAT or ACT and how many test dates you have taken.
- 2For the ACT, pick enhanced (2025 and later) or legacy format.
- 3Enter your section scores for each date, leaving untaken dates at 0.
- 4Read your superscore and compare it with your best single sitting.
- 5Check the table to see which date contributed each best section.
Formula and method
The calculator takes the highest score you earned in each section across all the sittings you enter, ignoring blank sittings. For the SAT it adds the best Reading and Writing and best Math section scores for a 400–1600 superscore. For the ACT it averages the best section scores that count toward the composite — English, Math and Reading on the enhanced ACT, all four sections on the legacy ACT — and rounds the average to the nearest whole number, with .5 rounding up, as ACT does for composites.
The best single sitting is the highest total or composite from any one date, and the gain is the difference. Colleges that superscore use this same method, though some recalculate from the scores you choose to send.

- SAT section scores (200–800)
- E, M, R, S
- ACT English, Math, Reading and Science scores (1–36)
Worked examples
SAT, two sittings
The best Reading and Writing (650) came from test 1 and the best Math (680) from test 2, so the superscore is 1330 — 30 points above the better single sitting of 1300.
SAT, three sittings
A third test with a 700 Math raises the best Math, so the superscore becomes 650 + 700 = 1350, even though no single sitting tops 1300.
Enhanced ACT, two sittings
Best English 30, Math 29 and Reading 31 average exactly 30.0. Each sitting on its own averaged 29.0, so superscoring adds a point. Science (best 28) is reported separately on the enhanced ACT.
Legacy ACT with Science in the composite
With Science counted, the best sections 30 + 29 + 31 + 28 = 118 average 29.5, which rounds up to 30. The single sittings averaged 28.5 and 28.75, both rounding to 29.
Frequently asked questions
What is a superscore?+
A superscore combines your highest section scores from different test dates into a new total. If you scored 650 Reading and Writing in March and 680 Math in June, your SAT superscore is 1330 even if neither sitting reached that total.
How do you calculate an ACT superscore?+
Take your best English, Math and Reading scores from any sittings (and Science on the legacy ACT), average them and round to the nearest whole number, with .5 rounding up. For example 30, 29 and 31 average 30.
Do all colleges accept superscores?+
No. Many colleges superscore the SAT, fewer superscore the ACT, and some consider only your highest single sitting or ask for all scores. Each college states its policy on its admissions website.
Does Science count in the ACT superscore?+
On the enhanced ACT launched in 2025, the composite is the average of English, Math and Reading; Science is optional and reported separately, so it does not affect the composite superscore. On legacy tests it counts as one of four sections.
Is it worth retaking the SAT or ACT to superscore?+
If your target colleges superscore, a retake can only raise your superscore, so focusing on your weakest section can pay off. At colleges that use only a single sitting, a retake helps only if the whole test improves, so check policies before booking another date.
