How to calculate GPA: accurate, fast and customizable

A Grade Point Average (GPA) summarizes your academic performance as a single number — typically the weighted average of grade point values times course credit hours. Different schools use different grade scales (some use A+ = 4.3, others treat A+ as 4.0, and some systems — like certain international or private institutions — may use different numeric mappings such as A+ = 10). This calculator helps you compute both weighted GPA (which accounts for course credits) and an unweighted average (simple points average) and supports custom grade mappings so the tool matches your institution’s policy.

Why use weighted vs unweighted GPA?

A weighted GPA multiplies each course’s grade point by its credit hours — that means a 4-credit course affects your GPA more than a 1-credit elective. Unweighted averages treat each course equally and are useful for quick comparison. College admissions and scholarship committees generally consider weighted GPA because it better reflects the workload.

How to use this GPA calculator

  1. Enter your course name (optional) so your records are clear.
  2. Enter credit hours (use fractional values like 0.5 if your school uses semester hours).
  3. Select the letter grade for each course (A+, A, A-, B+, …).
  4. Choose a preset grade scale (default A+ = 4.3) or open Customize grade points to set any numeric values (for example A+ = 10).
  5. Click Calculate GPA to get weighted GPA, unweighted average, and total credits.
  6. Click Generate Certificate to create a printable certificate — enter the student name and print to PDF.

Practical tips to improve your GPA

Focus on higher-credit courses where small improvements yield larger GPA gains. Repeating a course (if your school allows grade replacement) can raise your GPA, but check the institution’s policy first. For immediate improvements: target assignments and exams in 3–4 major courses and use office hours to clarify problem areas.

Frequently asked questions — GPA Calculator

How does this GPA calculator work?
Enter each course (name optional), the credit hours for that course, and select a letter grade from the dropdown. Choose a preset grade scale or open “Customize grade points” to set numeric values (for example A+ = 4.3 or A+ = 10). The calculator computes weighted GPA (total grade points ÷ total credits) and an unweighted average.
Can I set A+ (or any grade) to a custom numeric value?
Yes — open the Customize grade points panel, type the numeric value you want for each grade (A+, A, A-, etc.), click Save mapping and toggle Use custom mapping to apply it. The default preset uses A+ = 4.3.
Is this calculator official for transcripts or university applications?
No — this tool provides an estimate based on the grade-point mapping you choose. Always follow your institution’s official transcript and GPA rules for exact calculations required by universities or scholarships.
How do I export or save my course list and results?
Use the Export CSV button to download a CSV file containing your course names, credits, selected letter grades and numeric points. You can also generate a printable certificate and save it as PDF via your browser’s Print dialog.
What should I do if long course names break the layout on small screens?
The calculator uses responsive CSS and will wrap long text. If you still see overflow, shorten the course name or enable stacking for very small screens (we can add that CSS if you want). The Export CSV keeps full names intact.
How can I save my custom grade mapping and courses between visits?
Currently the tool does not persist data across reloads. I can add localStorage support so your saved custom mapping and course list are restored on next visit — tell me if you want that.
