SAT to IQ at a glance

A 1400 SAT points to an IQ of about 117, with a likely range of 106–129. A 1200 points to about 109 (97–121), and a perfect 1600 to about 131 (119–143).

The SAT is not an IQ test, so no conversion is exact. These figures come from a statistical model: the SAT tracks general intelligence closely (about .8 in a large US study) but not perfectly, and high scores regress towards the average. If the SAT were a flawless IQ measure, a 1400 would mean IQ 123. It is not, so the honest estimate is lower and comes with a range.

SAT to IQ conversion chart

Every row below comes from the same model as the calculator. The likely range covers about four in five people at that score. The last column shows what the IQ would be if the SAT were a perfect measure of IQ, which is the number many other converters publish.

IQ to SAT: what score to expect

Going the other way, this table shows the SAT score people at each IQ typically get. Scores at the same IQ vary widely, so the range matters more than the middle figure.

Typical SAT score by IQ
IQ	Typical SAT score	Likely range	How rare is this IQ
85	810	650 to 1000	1 in 6 at or below
90	860	710 to 1070	1 in 4 at or below
100	990	800 to 1220	1 in 2 at or above
110	1140	910 to 1360	1 in 4 at or above

One IQ, several tests: SAT next to other scores

The same IQ shows up as very different numbers on different tests. This table shows the typical score at each IQ on SAT and on the tests closest to it. Read across a row to compare, for example, what an SAT and an ACT would each be for the same person.

Typical score by IQ across SAT, ACT, GRE, LSAT, ASVAB
IQ	SAT	ACT	GRE	LSAT	ASVAB
100	990	17	298	148	50
110	1140	21	306	153	70
120	1280	25	315	159	86
130	1410	30	323	164	95
140	1530	33	332	169	98

These are typical scores, not guarantees. Every test has its own likely range, shown on its page.

What the SAT measures, and how close that is to IQ

The SAT tests reading, writing and maths as taught in US schools. It is an achievement test on the surface, but achievement tests that sample many skills end up measuring general ability as well, because people who learn quickly do well across all the sections.

That overlap has been measured. Frey and Detterman (2004) compared SAT scores with a general-ability score built from the ASVAB military battery for 917 people from a national US sample. The correlation was .82. In a second study of 103 university students, the SAT correlated .48 with Raven's Advanced Progressive Matrices, or .72 after correcting for the fact that university students are a narrow slice of ability.

Two cautions apply. Those studies used the SAT as it was before 1995, and the "IQ" was a general-ability score from the ASVAB, not a Wechsler test. Nobody has published a large modern comparison of the current SAT with a Wechsler scale, so every SAT to IQ converter, this one included, is extrapolating.

Why a 1600 does not mean IQ 160

Many converters simply line up percentiles: the SAT's top 1% becomes IQ 135 or so, and a near-perfect score becomes 145 to 160. That answers "how rare is this score?" It does not answer "how smart is this person?", because the SAT and IQ are only partly the same thing.

When two measures correlate at about .75, a person who is far above average on one is usually above average on the other but not as far. Statisticians call this regression to the mean. It is why the tall parents of tall children still tend to have children slightly closer to average height. Applied here, a 1600 is very rare (fewer than 1 in 100 test-takers), yet the most likely IQ behind it is about 131, with people scoring 1600 plausibly anywhere from 119 to 143.

The marker on the chart above shows the other reading. If the SAT measured IQ perfectly, a 1600 would equal IQ 140. The truth sits between the two, which is why a range is more useful than a point.

Old SAT scores, the 2016 redesign and the digital SAT

The scale has moved more than once. The SAT was recentred in 1995, which raised typical scores by roughly 100 points, and it was redesigned again in 2016 to the 400 to 1600 scale used now. The digital SAT, introduced in the US in March 2024, kept the 400 to 1600 scale but made each section adaptive: your performance on the first module decides how hard the second one is.

This converter uses the current scale and the Class of 2025 norms. If your score is from before 1995, a 1300 then is not a 1300 now, and pre-1995 charts (including the numbers in the research above) should not be read against today's table. College Board has published concordance tables between older and current scales if you need to translate an older score first.

Mensa is a useful reference point here. American Mensa accepted an SAT score of 1300 before September 1974 and 1250 from September 1974 to January 1994. It accepts no SAT scores taken after 31 January 1994, so an SAT cannot qualify you for Mensa today.

What your SAT score means

Read these as a guide to how your score compares with other test-takers, not as a verdict on intelligence. The estimated IQ column shows the most likely value, with the likely range in brackets.

What SAT score bands mean
Score	Estimated IQ	What it means
Below 900	67 to 97	Below the middle of test-takers. The estimated IQ sits between about 90 and 100, but the range is wide: the SAT punishes gaps in school knowledge, and people with average or higher ability get low scores for many reasons.
900 to 1090	97 to 105	Around the median. The typical estimate is within a few points of 100. This band contains a large share of all US test-takers.
1100 to 1290	105 to 112	Above average. Most people here have above-average general ability, and the estimated IQ sits in the 100s to low 110s.
1300 to 1390	113 to 117	Clearly strong: roughly the top 15% of test-takers. The estimated IQ moves into the high teens above 100.
1400 to 1490	117 to 121	Top 7% of test-takers. Competitive for selective universities. The estimate is around IQ 117 to 121, with a range that reaches into the 130s.
1500 to 1600	122 to 131	The top few percent. Extremely rare, and also the range where preparation, retakes and test-taking skill account for more of the gap between people than they do lower down.

Why a SAT score is not an IQ

It measures learned content as well as reasoningAlgebra, grammar conventions and vocabulary in context are taught. Someone with strong reasoning but weak schooling scores lower than their ability, and the reverse is also common.
Preparation and retakes raise scoresPractice and coaching lift SAT scores without changing underlying reasoning much. Your best score across attempts is the one most people quote, and it is biased upwards.
The top of the scale is compressedAbout 200 points separate the top 10% of test-takers from the top 1%, and a few questions can move a score by tens of points. Small differences at the top mean little.
Who takes the test has changedWith school-day testing in many states, today's test-takers are closer to a typical cross-section of US students than the self-selected group of the past. The model assumes they are a little above average in IQ, and that assumption is ours, not College Board's.

The evidence behind these numbers

Evidence grade: Moderate

The SAT is one of the few tests here with a published comparison to a general-ability measure. It is still a comparison with a military battery, on the pre-1995 SAT, not with a Wechsler test on today's digital SAT.

Published facts we used

SAT and ASVAB-derived general ability: r = .82 (N = 917), and .86 allowing for a curved relationship (Frey and Detterman, 2004).
SAT and Raven's Advanced Progressive Matrices: r = .48, or .72 corrected for restricted range (N = 103).
Class of 2025 mean 1029, SD 235, about 2.0 million test-takers (College Board annual report).
Percentile table for actual test-takers (College Board score interpretation pages).

Assumptions we made

Mean IQ of SAT test-takers: 102. Roughly half of US graduates now take the test, and school-day testing has brought the pool close to the general population. This is our assumption.
IQ spread among test-takers: SD 14, slightly under 15 because test-takers are a selected group.
Correlation between SAT and IQ among test-takers: .75, chosen below the published .82 because selected groups show weaker correlations and the studies used an older SAT.

Assumed test-taker IQ: mean 102, SD 14
Assumed correlation (r): 0.75
Likely range: The score at which about 80% of people with that estimate fall, from the residual spread after regression
Norms: College Board Class of 2025 annual report and score percentile tables.

SAT to IQ: frequently asked questions

What SAT score equals an IQ of 130?+

People with an IQ of 130 typically score around 1410 on the SAT, and about four in five land between 1190–1580. The spread is wide because preparation and knowledge matter as well as ability.

Is a 1400 SAT a good IQ?+

A 1400 is in the top the top 7% of test-takers. It points to an IQ of about 117, most likely within 106–129. That is above average, but the SAT cannot say exactly where.

Is the SAT an IQ test?+

No. It is an achievement and aptitude test. It correlates strongly with IQ, at roughly .8 in the best published study, but it also rewards schooling, preparation and test-taking skill.

What IQ do you need for a 1600 SAT?+

There is no minimum. The most likely IQ for a perfect score is about 131, with a plausible range of 119–143. Some 1600 scorers are exceptionally able, others are strong, well-prepared students.

Does Mensa accept SAT scores?+

Only old ones. American Mensa accepts 1300 before September 1974 and 1250 from September 1974 to January 1994. It accepts no SAT taken after 31 January 1994.

How accurate is an SAT to IQ conversion?+

It is a statistical guess with a margin of roughly 12 points either side for four in five people. It is fine for curiosity and rough comparison. It is not a substitute for a supervised IQ test.

Does the digital SAT change the conversion?+

The 400 to 1600 scale is unchanged, so the same table applies. The adaptive format may change how scores are reached, but no research yet links the digital SAT to IQ.
