ACT to SAT Score Converter
Convert ACT scores to SAT and SAT to ACT using College Board concordance tables.
Returns equivalents for composite, math, and reading with percentile rankings.
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 (selected scores):
| ACT Composite | SAT Total (1600 scale) |
|---|---|
| 36 | 1590 |
| 35 | 1540 |
| 34 | 1500 |
| 33 | 1460 |
| 32 | 1420 |
| 31 | 1380 |
| 30 | 1360 |
| 29 | 1320 |
| 28 | 1290 |
| 27 | 1250 |
| 26 | 1210 |
| 25 | 1180 |
| 24 | 1150 |
| 23 | 1110 |
| 22 | 1080 |
| 20 | 1020 |
| 18 | 950 |
| 16 | 880 |
Approximation formula (for quick estimates when the table is unavailable):
SAT ≈ (ACT × 40) + 150 (valid in the 20–36 range)
Example: ACT 28 → (28 × 40) + 150 = 1,270 (concordance table shows 1,290 — close enough for planning)
Worked example: ACT composite score: 26 Concordance table equivalent: 1,210 SAT Approximate formula: (26 × 40) + 150 = 1,190 (within acceptable margin)
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.
