About the PSAT Score Calculator
This PSAT score calculator turns a practice-test result into estimated PSAT/NMSQT scores. Enter how many questions you answered correctly in Reading and Writing (out of 54) and Math (out of 44); it converts each raw score to the 160–760 section scale using a sample conversion curve, rounds to the nearest 10, adds the sections for a 320–1520 total and works out the National Merit Selection Index.
It suits sophomores and juniors tracking progress between Bluebook practice tests, students setting a National Merit goal, and tutors planning which section to work on. The table shows what each raw score is worth on both sections, so you can see how many more correct answers reach a target.
The digital PSAT/NMSQT is adaptive and weighted by question difficulty, so College Board does not publish a single raw-to-scale table. The curve here is a representative sample that assumes you reached the harder second module in each section; if you were routed to the easier module, your actual score will usually be lower. Treat results as an estimate within roughly ±30 points per section, and use your official Bluebook score report for exact numbers.
With the default inputs, the estimated total score (320–1520) is 1,200. Change any value above to recalculate instantly.
How to use the psat score calculator
- 1Take a full digital PSAT/NMSQT practice test in Bluebook.
- 2Count your correct answers in Reading and Writing (out of 54).
- 3Count your correct answers in Math (out of 44).
- 4Enter both counts to see estimated section scores, total and Selection Index.
- 5Check the table to see how many more correct answers reach your target.
Formula and method
The digital PSAT/NMSQT has 54 Reading and Writing and 44 Math questions, with no penalty for wrong answers. Each raw score is mapped to the 160–760 section scale with a sample piecewise-linear curve (for example 40/54 ≈ 600 and 32/44 ≈ 600), rounded to the nearest 10. The two sections add up to the 320–1520 total.
The Selection Index uses College Board’s published formula: double Reading and Writing, add Math and divide by 10. Real scoring is adaptive and uses item response theory, so harder questions count for more and the same raw score can map to different scale scores on different forms. A few questions in each section are unscored pretest items you cannot identify, which is another reason a raw-count estimate is approximate.

Worked examples
Solid practice test
40 of 54 in Reading and Writing maps to about 600 and 32 of 44 in Math to about 600, for an estimated 1200 total. The Selection Index is (1,200 + 600) ÷ 10 = 180.
National Merit contender
Missing four Reading and Writing questions gives about 710 and missing two Math questions about 730, a 1440 total. The estimated Selection Index of 215 is near many states’ Semifinalist cutoffs.
Half the questions right
27 of 54 interpolates to about 496, which rounds to 500, and 20 of 44 is about 480, giving roughly 980. The Selection Index is (1,000 + 480) ÷ 10 = 148.
Frequently asked questions
How is the PSAT scored?+
The digital PSAT/NMSQT has two sections, Reading and Writing and Math, each scored from 160 to 760, for a total from 320 to 1520. Scores depend on how many questions you answer correctly and their difficulty; wrong answers are not penalised.
How many questions are on the PSAT/NMSQT?+
Reading and Writing has 54 questions in 64 minutes and Math has 44 questions in 70 minutes, split into two adaptive modules each. The whole test takes 2 hours 14 minutes.
Why is the maximum PSAT score 1520 and not 1600?+
The PSAT/NMSQT is reported on the same vertical scale as the SAT but tops out at 760 per section, because it is designed for 10th and 11th graders and includes fewer of the hardest questions.
What is a good PSAT score?+
It depends on your goals. Your official score report shows percentiles comparing you with other students in your grade, which is the best yardstick for a total. For National Merit, what matters is your Selection Index compared with your state’s Semifinalist cutoff.
Is there an official PSAT raw score conversion chart?+
Not for the digital PSAT. Because the test is adaptive, College Board scores each student with item response theory instead of a fixed chart. Bluebook practice tests give you an official score; this calculator gives a quick estimate from your raw counts.
