GPA Calculator
Letter grades in, credit-weighted GPA out — the standard unweighted 4.0 scale used by most US colleges.
Unweighted 4.0 scale (A+ = 4.0, steps of 0.3). Your registrar's number is official.
How GPA is computed
Each letter grade maps to grade points (A = 4.0, A- = 3.7, B+ = 3.3 …), each course's points are multiplied by its credit hours, and the total is divided by total credits. A 3-credit A and a 1-credit C average to 3.5, not 3.0 — credits matter.
Worth knowing
Confirm the scale in your syllabus
The 90/80/70/60 letter cutoffs used here are the most common US scale, but plenty of courses curve, use plus/minus bands differently, or set an A at 94. The syllabus — not any calculator — is the contract that counts.
The registrar's number wins
Online gradebooks lag, professors enter marks late, and rounding policies differ by course. Any calculator — including this one — is a planning tool; the transcript is the record.
Common questions
What GPA do I need for the Dean's List?
Most schools set Dean's List between 3.5 and 3.7 for the semester, with a minimum credit load (often 12+ graded credits). It's a semester GPA, not cumulative — one strong term can make the list even in a rebuilding year. Your school's exact cutoff will be published by the registrar.
Can I still pass if I fail the final?
Often, yes — it depends on your current grade and the final's weight. With an 80 going in and a final worth 20%, even a 40 on the final leaves you at 72. Run your exact numbers in the calculator; 'failing the final means failing the class' is only true when the final is very heavily weighted or your cushion is thin.
Do these calculators store my grades?
No. Everything is computed in your browser the moment you press Calculate — nothing is uploaded, saved or seen by anyone else. Refresh the page and it's gone.
