How It Works

How to Calculate Your SAT Score

The SAT total score is the sum of two section scores, each ranging from 200 to 800.

Formula

Total SAT Score = Reading & Writing Score + Math Score

Scores range from 400 (minimum) to 1600 (maximum).

Worked Example

A student scores 580 on Reading & Writing and 570 on Math.

reading_writing = 580math = 570
  1. 01Total SAT = 580 + 570 = 1150
  2. 02Estimated percentile = round((1150 - 400) / 1200 * 100) = 63
  3. 03Section difference = 580 - 570 = 10 (stronger in R&W)
