MCAT Score Calculator — Total Score & Percentile Estimate

Add up your four MCAT section scores into a Total Score (472-528) and estimate your percentile rank using AAMC's current-cycle mean and standard deviation.

Each section score is 118-132. Total range is 472-528.

MCAT Total Score
500 / 528
≈ 48.2th percentile (normal-approximation estimate)

This percentile is an estimate, not the official AAMC percentile table row. It's calculated from a normal-distribution approximation using the current cycle's published mean (500.5) and standard deviation (11.2), effective May 1, 2025 - April 30, 2026. AAMC's real published percentile table isn't perfectly normal at the low and high tails, so if precision matters — for example, citing an exact percentile on a med school application — check the official row at students-residents.aamc.org/mcat-research-and-data/percentile-ranks-mcat-exam.

Total Score = Bio/Biochem + Chem/Physical + CARS + Psych/Social/Bio section scores, each scaled 118-132 (total range 472-528). This calculator does not convert raw number-of-questions-correct into a section score, because AAMC does not publish a universal raw-to-scaled conversion table — every test form is equated and scaled separately. The percentile shown here applies a standard-normal-distribution formula (percentile = Φ((score − mean) ÷ SD) × 100) to AAMC's current published cycle mean and standard deviation as a planning estimate, not the official percentile lookup.

Worked Examples

Above-Average Total Score

Bio/Biochem Foundations
128
Chem/Physical Foundations
129
CARS
126
Psych/Social/Bio Foundations
128
Total 511 — ≈82.6th percentile (estimate)

128+129+126+128 = 511. z = (511-500.5)/11.2 = 0.94, which places the normal-approximation percentile at about 82.6 — meaning an estimated 82.6% of test-takers in the current AAMC data window scored at or below 511.

Exact Midpoint Total Score

Bio/Biochem Foundations
125
Chem/Physical Foundations
125
CARS
125
Psych/Social/Bio Foundations
125
Total 500 — ≈48.2th percentile (estimate)

125×4 = 500, the exact numeric midpoint of the 472-528 scale. Because the current cycle's actual mean (500.5) is very slightly above 500, a total of exactly 500 lands just under the 50th percentile rather than exactly at it.

High Total Score

Bio/Biochem Foundations
130
Chem/Physical Foundations
131
CARS
129
Psych/Social/Bio Foundations
130
Total 520 — ≈95.9th percentile (estimate)

130+131+129+130 = 520. z = (520-500.5)/11.2 = 1.74, giving a normal-approximation percentile near 95.9 — competitive at most MD programs, though official AAMC table rows should be checked for a specific application.

Below-Average Total Score

Bio/Biochem Foundations
122
Chem/Physical Foundations
123
CARS
121
Psych/Social/Bio Foundations
124
Total 490 — ≈17.4th percentile (estimate)

122+123+121+124 = 490. z = (490-500.5)/11.2 = -0.94, giving a normal-approximation percentile near 17.4 — meaningfully below the current-cycle mean of 500.5.

Minimum Possible Total Score

Bio/Biochem Foundations
118
Chem/Physical Foundations
118
CARS
118
Psych/Social/Bio Foundations
118
Total 472 — ≈0.5th percentile (estimate)

118×4 = 472, the lowest total the scale allows. z = (472-500.5)/11.2 = -2.54, a percentile the normal approximation places near the bottom half of one percent — though the true distribution has a floor effect the normal curve doesn't fully capture at this extreme tail.

What Each Value Means

MCAT Total Score (score (472-528))
The sum of all four MCAT section scores. Each section is scaled 118-132, so Total Score ranges from 472 to 528, with 500 as the exact numeric midpoint.
MCAT Section Score (score (118-132))
The scaled score (118-132) for one of the four MCAT sections: Biological and Biochemical Foundations of Living Systems, Chemical and Physical Foundations of Biological Systems, Critical Analysis and Reasoning Skills (CARS), and Psychological, Social, and Biological Foundations of Behavior.
Percentile Rank (normal-approximation estimate) (percentile (0-100))
An estimate of what share of test-takers scored at or below a given Total Score, calculated from a standard normal distribution using AAMC's current-cycle published mean and standard deviation. Not identical to AAMC's official percentile-rank table, which reflects the true (not perfectly normal) distribution of real scores.

Frequently Asked Questions

Why doesn't this calculator convert my number of correct answers into a section score?
Because no universal table for that exists. AAMC calibrates the raw-score-to-scaled-score conversion separately for every individual MCAT test form, adjusting for that form's specific difficulty through a process called equating — a raw score of 55 correct on a section might scale to a 128 on one test date and a 127 on another. AAMC does not publish these per-form conversion charts. Any calculator claiming a fixed 'raw answers correct to MCAT score' chart is presenting an approximation as fact, which this tool avoids by starting from section scores (118-132) you already have or are estimating from an official AAMC practice exam's own scoring key.
How accurate is the percentile estimate on this calculator?
It's a normal-distribution approximation, not the official AAMC percentile table. AAMC publishes its real percentile ranks from the actual distribution of scores in a rolling 3-year window of test-takers, refreshed every May 1 — and that real distribution isn't perfectly bell-shaped, especially at the very top and bottom of the scale, where scores bunch up differently than a normal curve predicts. This calculator's estimate (using the current cycle's published mean of 500.5 and standard deviation of 11.2) will be close to the official number in the middle of the range, but can drift a percentile point or two at the extremes. If you're citing a percentile for a school application or scholarship threshold, look up the exact row on AAMC's official percentile-ranks page instead of relying on this estimate alone.
What is a good MCAT total score?
It depends entirely on your target schools. The current-cycle mean total score is 500.5, so a 500 is almost exactly average among all test-takers. Scores in the 508-513 range are roughly competitive at many mid-tier MD programs, 514-517 is squarely in range for many top-25 research-focused schools, and 518+ is in the upper single-digit percentiles nationally. Always check your specific target schools' published median MCAT for matriculants (found in each school's MSAR profile) rather than relying on a single 'good score' number — a 510 is outstanding for one program's applicant pool and below-median for another's.
Does AAMC's percentile table change over time?
Yes. AAMC refreshes the percentile-rank table every May 1, rebuilding it from a new rolling 3-year window of test administrations. The version this calculator's normal-approximation is based on (mean 500.5, SD 11.2, 293,882 exams) reflects the cycle effective May 1, 2025 through April 30, 2026, built from 2022-2024 data. A score's exact percentile can shift by a point or two from one cycle to the next even if the score itself never changes, simply because the comparison population changed — which is another reason to check the live AAMC page rather than treating any single percentile number as permanent.
Does this calculator replace my official AAMC score report?
No. Your official score report from AAMC is the only authoritative source for your actual section scores, Total Score, and official percentile rank. This tool is for planning and estimation — combining known or practice-exam section scores into a Total Score, and translating that Total Score into an approximate percentile for planning purposes. Always submit and rely on your official AAMC score report for the exact numbers medical schools will see.
