Calculating your PSAT score after a practice test takes just a few steps: count your correct answers (the raw score), convert to a scaled score using a conversion table (160-760 per section), and add your two section scores together for a total (320-1520). This guide walks you through every step with the conversion tables you need.
Whether you just finished a practice test and want to know your projected PSAT score, or you are trying to predict what raw score you need for a target scaled score, this calculator approach will give you a reliable estimate. For full official scoring, the College Board Bluebook app calculates scores automatically, but knowing how the math works helps you set targets and track progress.
How PSAT Scoring Works
The PSAT scoring process has four steps:
- Raw score: Count the number of correct answers per section. There is no penalty for wrong answers, so your raw score equals the number of questions you answered correctly.
- Scaled score: Convert the raw score to a scaled score (160-760 per section) using a conversion table. The conversion adjusts for slight differences in test difficulty.
- Total score: Add your two section scores together for your PSAT total (320-1520).
- Selection Index: A separate calculation used for National Merit Scholarship qualification (48-228).

How to Calculate Your PSAT Total Score
Once you have both section scores, calculating your total is simple:
Total PSAT Score = Math Scaled Score + Reading and Writing Scaled Score
The total ranges from 320 (160 + 160) to 1520 (760 + 760).
Example Calculation
Suppose you took a PSAT practice test and got:
- Math: 35 correct out of 44 → raw score 35 → scaled score approximately 630-660 → let's say 645
- Reading and Writing: 42 correct out of 54 → raw score 42 → scaled score approximately 600-630 → let's say 615
- Total PSAT Score: 645 + 615 = 1260
A score of 1260 falls around the 86th percentile for juniors, which is above average and predicts an SAT score of around 1310-1380 with focused preparation. To see how your score compares nationally, see Average PSAT Score.
How to Calculate Your PSAT Selection Index
The Selection Index is a separate score used for National Merit Scholarship qualification. It ranges from 48 to 228 and is calculated from your section scores, with Reading and Writing weighted double.
Selection Index = (2 × Reading and Writing score + Math score) / 10
Example Calculation
Using the example above:
- Reading and Writing: 615
- Math: 645
- Selection Index: (2 × 615 + 645) / 10 = (1230 + 645) / 10 = 1875 / 10 = 188
And the maximum possible Selection Index, with perfect 760s in both sections:
- Reading and Writing: 760
- Math: 760
- Selection Index: (2 × 760 + 760) / 10 = (1520 + 760) / 10 = 2280 / 10 = 228 (maximum)
Because Reading and Writing counts double, a strong Reading and Writing score helps your Selection Index more than an equally strong Math score. Two students with the same total PSAT score can have different Selection Indexes if their section scores are weighted differently.
To qualify as a National Merit Commended Student, you needed a Selection Index of 210 for the Class of 2026 (October 2024 PSAT). To qualify as a Semifinalist, you need to score above your state cutoff, which ranged from 210 (smaller states) to 225 (Massachusetts and New Jersey) for the Class of 2026. See PSAT Score Range for state-by-state cutoff details.
What Your Score Means
Once you have calculated your scaled score, here is how to interpret it:
For more on what counts as a good score by grade level, see What Is a Good PSAT Score? For predicting your SAT score from your PSAT score, see PSAT to SAT Score Conversion.
Why the Conversion Is Approximate
The College Board uses a process called equating to ensure that a score of 600 on one PSAT means the same as a 600 on another, even though the tests have slightly different difficulty levels. Each test form has its own equating curve, which is why the conversion table above is approximate rather than exact.
If you took a particular practice test, the answer key usually includes the official conversion table for that specific form. The Bluebook app handles all of this automatically. If you are estimating from a third-party practice test or from individual sections, the table above gives you a reliable approximation but may be off by 10-20 points in either direction.
Adaptive Format and Score Calculation
The Digital PSAT uses a two-module adaptive format. Your performance on Module 1 determines whether you receive a harder or easier Module 2. This affects scoring in a few important ways:
- Higher difficulty Module 2: Each correct answer is worth slightly more, since the questions are harder. The score ceiling is higher (you can reach 700-760).
- Lower difficulty Module 2: Each correct answer is worth slightly less, since the questions are easier. The score ceiling is capped (typically around 600-650 maximum).
This means a perfect score on the lower-difficulty Module 2 does NOT result in a 760. It results in roughly the maximum score for the lower-difficulty path, which is typically around 600-650. The College Board does this to maintain comparable difficulty across all students at each score level.
The takeaway: Doing well on Module 1 matters a lot. It unlocks the higher-difficulty Module 2, which is the only path to the upper score range. This is why focused early-test accuracy is critical.
How to Use the Calculator for Goal Setting
The PSAT score calculator is most useful for setting realistic targets and tracking progress. Here is how to use it:
Set a Target Total Score
Decide what total PSAT score you want. Common targets:
- 1100: Above average, comfortable starting point for SAT prep
- 1200: Strong starting point, predicts a 1280-1380 SAT
- 1300: Top 10%, very strong PSAT performance
- 1400: National Merit Semifinalist range in most states
Calculate Required Section Scores
Divide your target by 2 to get the average section score, then adjust based on your strengths:
Example: Target = 1300. Average = 650 per section. If you are stronger in Reading and Writing, you might aim for 680 R&W and 620 Math, for the same total.
Calculate Required Raw Scores
Use the conversion tables above to figure out how many questions you need to answer correctly per section:
Example: To hit 650 in Math, you need a raw score of around 35-37 out of 44 (about 80%). To hit 650 in Reading and Writing, you need a raw score of around 47-49 out of 54 (about 90%).
Track Progress
After each practice test, calculate your scores using these tables and compare to your targets. If you are consistently below your target raw score in a specific section, that is where to focus your prep.
Frequently Asked Questions About PSAT Score Calculation
Is there an official PSAT score calculator?
The College Board Bluebook app calculates your scores automatically when you take an official practice test. For estimating scores from raw counts, the conversion tables above give you a reliable approximation.
How do I convert my PSAT raw score to a scaled score?
Look up your raw score (number of correct answers per section) in the conversion table for that section. The table shows your approximate scaled score (160-760). Add your two section scores together for your total PSAT score (320-1520).
What is the highest possible PSAT score?
The maximum PSAT score is 1520 (760 in Reading and Writing + 760 in Math). The maximum Selection Index is 228. The PSAT's ceiling is lower than the SAT's 1600 because the PSAT excludes some of the hardest question types found on the SAT. See PSAT Score Range for more details.
How accurate is my estimated PSAT score?
The conversion tables above are approximations. The actual conversion varies between test forms and is calculated by the College Board through a process called equating. If you use the Bluebook app, your score is calculated exactly. If you use these tables, expect a margin of error of about 10-20 points in either direction.
Why does perfect performance on the lower-difficulty module not give a perfect score?
The PSAT uses an adaptive format. Module 1 includes a mix of difficulty levels, and your performance determines which version of Module 2 you receive. The lower-difficulty Module 2 has an upper score cap (typically around 600-650) because its questions are easier. To reach the upper score range (700-760), you must perform well enough on Module 1 to unlock the higher-difficulty Module 2.
How is the Selection Index calculated?
Selection Index = (2 × Reading and Writing score + Math score) / 10. The Reading and Writing section counts double in the formula. The maximum is 228 (perfect 760 in both sections), and the minimum is 48. The Selection Index is used only for National Merit Scholarship qualification.
What raw score do I need for a 1400 PSAT?
To reach 1400, you need approximately 700 in each section. That requires roughly 40-41 correct out of 44 in Math and 48-50 correct out of 54 in Reading and Writing. You can have a slightly lower raw score in one section if you have a higher raw score in the other.
Does the PSAT use the same scoring as the SAT?
The scoring philosophy is the same (raw score → scaled score, no penalty for wrong answers, two-section adaptive format). The score scales are different, however: the PSAT runs from 320 to 1520, while the SAT runs from 400 to 1600. This 80-point gap reflects the SAT's slightly harder question types. For converting between the two, see PSAT to SAT Score Conversion.
