Formula Used
Baseline SAT estimate = 2018 PSAT total score on the common scale.
Projected SAT estimate = baseline SAT estimate + expected monthly gain × months until SAT.
Final projected score is capped between 400 and 1600.
Confidence range = projected SAT estimate ± selected confidence band.
Target gap = target SAT score - projected SAT estimate.
Estimated Selection Index = ((2 × Reading and Writing section) + Math section) ÷ 10.

Understanding 2018 PSAT to SAT Planning
A 2018 PSAT score can guide SAT planning with care. The PSAT/NMSQT and SAT shared a common scale for total and section scores. That means a PSAT Math score near 620 represented about the same achievement level on SAT Math that day. The difference is range. The PSAT stopped at 1520 total. The SAT could reach 1600.
Why Direct Alignment Matters
Many students add points automatically. That can create a false target. A direct aligned estimate is safer. It shows the SAT score you might have earned under similar conditions. Growth should be added separately. This calculator separates baseline conversion from planned improvement. That keeps the result useful for tutors, parents, and students.
Using Section Scores
Section scores give better guidance than total scores alone. A total score may hide a weak side. For example, 1180 can come from balanced skills. It can also come from strong reading and weaker math. The calculator accepts Reading and Writing and Math scores. It then builds a total estimate and shows section headroom. Headroom is the gap between the current section score and the SAT maximum.
Target and Growth Planning
The target field helps turn conversion into action. Enter the SAT score needed for a school, scholarship, or personal goal. Add months until testing and expected monthly gain. The tool creates a projected score. It also shows a confidence range. This range is not a promise. It is a planning band. Practice quality, test timing, sleep, and pacing can change results.
How to Read the Output
The baseline score is the simple 2018 PSAT to SAT estimate. The projected score includes your chosen growth setting. The target gap shows how many points remain. The study note suggests whether the plan needs review. Students near the top of the PSAT range should remember one issue. A perfect PSAT does not prove a perfect SAT. The SAT includes score space above the PSAT ceiling. Use the result as a guide, not a final verdict. Review missed skills. Practice timed sections. Track every test under realistic conditions. Share reports with advisors. Compare each attempt. Keep notes on errors, guessing, and time pressure. Small changes often create large gains later too.
FAQs
What does this calculator convert?
It converts a 2018 PSAT/NMSQT score into an aligned SAT estimate. It also adds optional growth planning, confidence range, target gap, and section headroom.
Is the PSAT score simply added to reach SAT?
No. The baseline estimate uses the same score number. Improvement points are added separately only when you enter months and expected monthly gain.
Why does PSAT stop at 1520?
The PSAT/NMSQT has a lower top score than the SAT. This means very high scorers still have SAT score space above the PSAT ceiling.
Should I use total score or section scores?
Use section scores when possible. They show whether Reading and Writing or Math needs more attention. Total score mode is useful when section data is missing.
What is the confidence band?
The confidence band creates a planning range around the projected score. A wider band is safer when practice history is limited or inconsistent.
What is target gap?
Target gap shows the points between your projected SAT score and your selected target. A positive gap means more improvement is still needed.
What is section headroom?
Section headroom shows how many points remain before the SAT section maximum of 800. It helps identify where improvement may still be available.
