What Is the MCAT Score Calculator?
This tool applies to the US AAMC Medical College Admission Test (MCAT). The current MCAT (administered since 2015) reports four separate section scores, each on a scale from 118 to 132. Your total score is simply the sum of those four sections, producing a combined score between 472 and 528, with a midpoint of 500. This calculator adds your sections instantly and gives you an approximate percentile based on AAMC norm patterns.
How to Use It
Enter your scaled score for each of the four MCAT sections: Chemical and Physical Foundations of Biological Systems (C/P), Critical Analysis and Reasoning Skills (CARS), Biological and Biochemical Foundations of Living Systems (B/B), and Psychological, Social, and Biological Foundations of Behavior (P/S). Each value must fall between 118 and 132. Click calculate to see your total and an estimated percentile.
The Formula Explained
The math is straightforward addition: $$\text{Total} = \text{C/P} + \text{CARS} + \text{B/B} + \text{P/S}$$. Because each section ranges 118–132, the minimum possible total is 472 (\(4 \times 118\)) and the maximum is 528 (\(4 \times 132\)). A score of 500 is the scaled midpoint, and roughly the 50th percentile. The percentile shown here is an approximation; official percentile ranks are published annually by the AAMC and shift slightly each cycle.
Worked Example
Suppose you scored 128 in C/P, 127 in CARS, 129 in B/B, and 126 in P/S. Adding these gives $$128 + 127 + 129 + 126 = \mathbf{510}.$$ A 510 is a strong, above-average total that historically sits near the 80th percentile.
FAQ
What is a good MCAT score? A total of 500 is average; 510+ is competitive for many schools, and 515+ is strong for top programs.
Why does the scale start at 472? Each section is scored 118–132 rather than starting at 1, so the floor of four sections is 472.
Is the percentile official? No — it is an estimate. Always check the current AAMC percentile rank tables for the exact figure for your testing cycle.
