Every SAT calculator you need, in one place
Prepping for the Digital SAT means juggling a lot of numbers. What does my raw score translate to? What percentile is that? How does it compare to an ACT score? How many days do I have left, and how many hours a week should I be studying? These free SAT tools answer each of those questions in seconds, with no sign-up and no catch.
Everything here is built for the current Digital SAT: two adaptive modules per section, a 200-800 section scale, a 400-1600 total, and the official 2026-2027 College Board test calendar. Each tool pairs an instant calculator with a deep explainer, so you get the answer and the context behind it.
How to use these tools together
They work best as a set. Score a Bluebook practice test, then run the raw counts through the Digital SAT score calculator to get a projected total. Drop that total into the percentile calculator to see where you rank nationally, or the SAT to ACT converter to compare it against an ACT composite. Then plan the work: the SAT countdown tells you how much runway you have, the study planner sizes your weekly hours, and the math formula sheet keeps the formulas you have to memorize in one spot. And when you're ready to raise the math score itself, our free Desmos SAT course teaches you to solve every Digital SAT math question type on the built-in graphing calculator.
