ACT to SAT Score Converter

ACT to SAT score conversion uses concordance tables developed jointly by College Board and ACT. These tables are derived from students who took both tests, providing statistically valid equivalence — not a mathematical formula with a single conversion factor.

Official concordance, full table. These are the 2018 tables published jointly by ACT and College Board. ACT states plainly that they are not updated annually, so the 2018 release is still the current one.

Approximation formula (for quick estimates when the table is unavailable):

SAT ≈ (ACT × 32) + 400

Across ACT 20 to 34 this lands within about 15 points of the official figure, which is inside a single SAT reporting increment for most of the range. It drifts low at the very top, where the table’s steps widen: at ACT 36 it gives 1,552 against the official 1,590.

Example: ACT 28 → (28 × 32) + 400 = 1,296. The table says 1,310, a gap of 14 points.

Worked example: ACT composite score: 26 Concordance table equivalent: 1,240 SAT Approximate formula: (26 × 32) + 400 = 1,232 (8 points under the table)

When to use the conversion:

• Checking if your ACT score meets a school’s SAT minimum requirement
• Comparing offers from test prep programs that quote one scale
• Choosing which test to take based on target score benchmarks

Important caveat: Individual scores vary — a student who scores 1,300 SAT may score a 28 or a 30 on the ACT depending on strengths. Concordance is a population average, not a guarantee.
