College GPA Calculator
Enter each course as a letter grade and its credit hours to calculate your credit-weighted GPA on the 4.0 scale.
College GPA is the credit-weighted average of your grade points. Convert each letter grade to points on the 4.0 scale (A = 4.0, B = 3.0, and so on), multiply by the course's credit hours, add those up, and divide by the total credits. Four courses earning 39 quality points across 12 credits give a GPA of 39 รท 12 = 3.25.
How to Use This Calculator
Enter one course per line, writing the letter grade first and then the number of credit hours, separated by a space or comma โ for example 'A 4' or 'B+, 3'. The calculator accepts plus and minus grades (A-, B+, and so on) and returns your credit-weighted GPA along with your total credits.
Include every course that counts toward the GPA you want. For a single term, list that term's courses; for your overall GPA, list all graded courses in your career (or use the cumulative GPA calculator to combine a prior GPA with a new term). Courses graded pass/fail usually carry no grade points and should be left out.
How the Calculation Works
Each letter grade maps to a grade-point value on the standard 4.0 scale: A and A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0. Multiplying a course's grade points by its credit hours gives its quality points. Your GPA is the total quality points divided by the total credit hours โ a weighted average that gives more influence to higher-credit courses.
Worked Example
Suppose you took four courses: an A in a 4-credit course, a B in a 3-credit course, a C in a 3-credit course, and an A in a 2-credit course. Quality points: 4.0 ร 4 = 16, 3.0 ร 3 = 9, 2.0 ร 3 = 6, and 4.0 ร 2 = 8, totaling 39. Total credits = 4 + 3 + 3 + 2 = 12. GPA = 39 รท 12 = 3.25. Note how the 4-credit A pulls harder on the average than the 2-credit A.
What the Result Means
Your GPA condenses your academic performance into a single number between 0.0 and 4.0. Because it is credit-weighted, grades in higher-credit courses matter more โ a strong grade in a 4-credit lab counts for twice as much as the same grade in a 2-credit seminar. Many programs set thresholds around 2.0 (good standing), 3.0 (many graduate programs and honors), and 3.5+ (competitive scholarships and admissions). To raise a GPA, focus on high-credit courses and remember that later credits move the average more slowly as your total grows.
Assumptions and Limitations
This uses the most common unweighted 4.0 scale. Some schools differ โ a few award 4.3 for an A+, some use plus/minus differently, and weighted high-school scales add points for honors or AP courses (use a high-school calculator for those). Pass/fail, audited, withdrawn and transfer credits are handled differently by each institution and are not included here. Always confirm your school's exact grade-point values and policies; treat this result as an accurate estimate on the standard scale.
When to Use a College GPA Calculator
College students use this to compute a credit-weighted GPA on the 4.0 scale from their courses. Run it to track a term, plan the grades needed for a target, or check standing for scholarships and programs. Enter each course's grade and credits to get the GPA.

Frequently Asked Questions
How is college GPA calculated?
Convert each letter grade to grade points on the 4.0 scale, multiply by the course's credit hours to get quality points, add them all, and divide by the total credit hours. It is a credit-weighted average.
What grade points does each letter get?
On the standard scale: A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0.
Why are credit hours part of the GPA?
Because a GPA is weighted by course size. A grade in a 4-credit course affects your GPA twice as much as the same grade in a 2-credit course, reflecting the greater workload.
Do pass/fail courses count toward GPA?
Usually no. Pass/fail courses typically earn credit but carry no grade points, so they do not affect your GPA. Leave them out of the calculation.
How do I raise my GPA quickly?
Earn strong grades in higher-credit courses, since they carry more weight. Be aware that as your total credits grow, each new term shifts the cumulative average more slowly.
Is an A+ worth more than an A?
On most 4.0 scales, no โ both are 4.0. A few schools award 4.3 for an A+, which can push a GPA slightly above 4.0. Check your institution's policy.
