Formula
GPA = Σ(grade points × course credits) ÷ Σ(course credits). Courses with zero credits are ignored because they add no credit weight.

Method
GPA = Σ(grade points × course credits) ÷ Σ(course credits). Courses with zero credits are ignored because they add no credit weight.
- Course quality points are grade × credits: 3.7 × 3 = 11.1, 3.3 × 3 = 9.9, 4.0 × 4 = 16 and 3.0 × 2 = 6. Total quality points are 43.0 over 12 credits, so GPA = 43.0 ÷ 12 = 3.58.
Assumptions
- Grade inputs use the grade-point values assigned by the school, commonly on a 0.0 to 4.0 scale.
- Credit inputs represent the weighting for each course, such as semester hours, credit hours or course units.
- Courses with zero credits are excluded from the weighted average.
- The calculator does not convert letter grades, honors weighting, pass/fail rules, repeated-course policies or institutional transcript rules unless those values are entered manually.

Worked example
Course quality points are grade × credits: 3.7 × 3 = 11.1, 3.3 × 3 = 9.9, 4.0 × 4 = 16 and 3.0 × 2 = 6. Total quality points are 43.0 over 12 credits, so GPA = 43.0 ÷ 12 = 3.58.
Professional note
Master’s Tip: print the credits and grade points beside the GPA. Most GPA disputes are not caused by division; they come from a wrong credit weight, repeated-course rule, school-specific scale or letter-grade conversion.
Regional and unit assumptions
Standard or basis: credit-weighted arithmetic average of grade points. The page uses transparent general GPA math and does not claim a universal school, college, university, NCAA, UCAS or immigration transcript rule.
Assumptions and limitations
- Grade inputs use the grade-point values assigned by the school, commonly on a 0.0 to 4.0 scale.
- Credit inputs represent the weighting for each course, such as semester hours, credit hours or course units.
- Courses with zero credits are excluded from the weighted average.
- The calculator does not convert letter grades, honors weighting, pass/fail rules, repeated-course policies or institutional transcript rules unless those values are entered manually.
- Official GPA for applications, scholarships, visas, athletics or graduation must come from the school record or the receiving institution.

Questions
How do you calculate GPA?
Multiply each course grade point by its credits, add those quality points, then divide by the total credits included in the calculation.
Is GPA a simple average?
Only when every course has the same credit weight. When credits differ, GPA is a weighted average, so a four-credit course affects the result more than a one-credit course.
What do I enter for an A or B grade?
Enter the grade-point value used by your school. A common 4.0 scale uses values such as A = 4.0, A− = 3.7, B+ = 3.3 and B = 3.0, but institutional scales vary.
Can this calculate cumulative GPA?
Yes, if you enter each term or course with the correct credits and grade points. For many completed courses, combine prior quality points and credits from the transcript, then add current courses.
Does this handle honors, AP or repeated courses?
Not automatically. Enter the weighted grade-point value your school actually applies and check official policy for repeated courses, pass/fail classes and excluded credits.
Calculation note
GPA is a weighted-average record used to summarize course performance across different credit values. The useful calculation is not just the final number; it is the quality-point trail that shows which grades and credits were included.
GPA is weighted by credit value
A course worth four credits should normally count more than a course worth one credit. That is why the calculator multiplies grade points by credits before averaging, instead of simply averaging visible grade numbers.
The grade scale comes from the institution
There is no single global grade-point scale. Some schools use plus/minus values, honors weighting, pass/fail exclusions or repeated-course replacement rules. This calculator handles the arithmetic after those grade-point values are chosen.
A printable worksheet helps transcript checks
A GPA report is useful when it keeps course grade points, credits, quality points, total credits, formula and date together. That makes a scholarship, advising, homeschool, classroom or transfer-planning discussion easier to audit.
