Short answer
GPA is the sum of (grade points × credit hours) divided by the total credit hours attempted, on a 4.0 scale.
What is the GPA Calculator?
Grade Point Average summarizes academic performance as a single number on a 4.0 scale, weighted by credit hours.
How does the GPA Calculator work?
Convert each letter grade to points. Multiply by credit hours to get grade points. Sum grade points and divide by total credit hours.
Formula
Variables
gradePointsA=4.0, A−=3.7, B+=3.3, B=3.0, B−=2.7, C+=2.3, C=2.0, C−=1.7, D=1.0, F=0creditsCredit hours for each course
Explanation
Weighting by credit hours prevents a 1-credit lab from having the same impact as a 4-credit lecture.
Examples
Example 1: A(3) + B+(4) + A−(3) + B(3)
Grade points 47.5 ÷ 13 credits ≈ 3.65 GPA.
Applications
- Semester GPA
- Cumulative GPA rollups
- Scholarship qualification
Advantages
- Weights heavier courses appropriately
- Follows the standard 4.0 US scale
Limitations
- Standard scale — schools with +/− policies or 5.0 scales require adjustment
Common mistakes
- Averaging GPAs across semesters instead of recomputing from grade points
Tips
- To combine semesters, sum grade points and credit hours across all semesters, then divide

Practical use cases and industry applications
Understanding GPA
Grade Point Average summarizes academic performance as a single number on a 4.0 scale, weighted by credit hours. Within math calculators, gpa belongs to the academic & grades cluster, where it shares terminology and assumptions with closely related tools.
Learning how gpa is calculated
Weighting by credit hours prevents a 1-credit lab from having the same impact as a 4-credit lecture. Working through the variables one at a time — gradePoints, credits — makes the result reproducible by hand and easier to sanity-check.
Using gpa to make a decision
Semester GPA Cumulative GPA rollups Scholarship qualification Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.
How gpa compares with related measures
credit hour, weighted mean, grading scale, percentile rank all describe adjacent aspects of academic & grades. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
Frequently asked questions
Does an A+ boost GPA above 4.0?
