What is GPA Calculator?

A GPA (Grade Point Average) calculator converts your letter grades and credit hours into a single number on the 4.0 scale. This is the standard measurement used by US high schools, colleges, and universities to evaluate academic performance. Our calculator supports the standard US 4.0 scale, the expanded US +/- scale (A through F with plus and minus modifiers), and UK percentage grades. You can add up to 20 courses per semester, enter previous cumulative GPA to calculate an updated cumulative GPA, and see Latin honors classification based on your results.

How It Works

Select your grading scale, then enter each course name, credit hours, and grade. The calculator computes quality points per course (credits × grade value) and divides total quality points by total credits to find your GPA. Optionally enter your previous cumulative GPA and total credits from prior semesters to compute an updated cumulative GPA. Results include GPA, Latin honors classification, and a detailed course breakdown table.

Formula

Quality Points = Credit Hours × Grade Points
Semester GPA = Total Quality Points / Total Credit Hours
Cumulative GPA = (Current Quality Points + Previous Quality Points) / (Current Credits + Previous Credits)

Formula Explained

Each letter grade has a numeric value: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. For the +/- scale, A- = 3.7, B+ = 3.3, etc. Multiply the grade value by the number of credit hours for each course to get quality points. Sum all quality points and divide by total credit hours. The result is your GPA on a 0.0-4.0 scale. For cumulative GPA, multiply your previous GPA by previous credits to recover prior quality points, combine with current semester, and divide by all credits.

Example

Mathematics: 4 credits × A (4.0) = 16.0 quality points English: 3 credits × B+ (3.3) = 9.9 quality points Physics: 4 credits × A- (3.7) = 14.8 quality points History: 3 credits × B (3.0) = 9.0 quality points Computer Science: 3 credits × A (4.0) = 12.0 quality points Total: 61.7 quality points / 17 credits = 3.63 GPA (Cum Laude)

Tips & Best Practices

✓Focus on high-credit courses to maximize GPA impact — an A in a 4-credit course matters more than in a 1-credit elective.
✓Use the cumulative GPA feature to track your progress across semesters.
✓If applying to UK universities from the US (or vice versa), use the UK percentage mode to understand grade equivalencies.
✓Many graduate programs have minimum GPA requirements (often 3.0) — use the calculator to see what grades you need.

Common Use Cases

•Calculating semester GPA for college students
•Computing cumulative GPA across multiple semesters
•Tracking academic progress toward Latin honors (Cum Laude, Magna, Summa)
•Converting UK percentage grades to the 4.0 scale
•Planning what grades are needed to reach a target GPA

Frequently Asked Questions

GPA = Total Quality Points / Total Credit Hours. For each course, Quality Points = Credit Hours × Grade Points (e.g., A = 4.0, B = 3.0). Add up all quality points and divide by total credits. On a 4.0 scale, an A in a 3-credit course earns 12 quality points, a B earns 9.

On the US 4.0 scale: 3.5-4.0 is excellent (Cum Laude or above), 3.0-3.49 is good (Dean's List at many schools), 2.0-2.99 is satisfactory, and below 2.0 may result in academic probation. Graduate school admissions typically look for 3.0+. Top programs may expect 3.5+.

Semester GPA reflects grades from a single term. Cumulative GPA includes all courses across all semesters. To calculate cumulative GPA, add all quality points from every semester and divide by total credits taken. Our calculator supports both — enter previous GPA and credits to compute cumulative.

On the standard +/- scale: A+ and A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, and so on. The +/- system provides more precision but can lower your GPA if you get A- instead of A. Some schools use +/- and others don't — check your institution's policy.

UK universities use percentage grades rather than letter grades. Common conversion: 70%+ (First Class) ≈ 4.0 GPA, 60-69% (Upper Second) ≈ 3.0-3.9, 50-59% (Lower Second) ≈ 2.0-2.9, 40-49% (Third Class) ≈ 1.0-1.9. This mapping varies by institution and is approximate.
