How It Works
Enter Each Course
Enter each course, its letter grade (or percentage), and its number of credit hours.
Choose GPA Type
Choose weighted or unweighted GPA, depending on whether your school gives extra grade points for AP/honors courses.
Add Previous Semesters

What Is a GPA Calculator?
A GPA (Grade Point Average) calculator converts letter grades or percentage scores into numeric grade points, then averages them — usually weighted by course credit hours — to produce a single number, typically on a 4.0 scale. GPA is used by high schools, colleges, and universities to summarize a student's overall academic performance.
Our GPA Calculator lets you enter your courses, grades, and credit hours to instantly calculate your semester GPA, cumulative GPA, or weighted GPA (for honors and AP classes).
Why Use an Online GPA Calculator?
- Avoids manual conversion errors between letter grades, percentages, and grade points.
- Handles credit-hour weighting automatically, so a 4-credit course counts more than a 1-credit course.
- Supports weighted GPA for AP, IB, and honors classes that use a 5.0 scale instead of 4.0.
- Projects future GPA, showing what grades you'd need next semester to reach a target cumulative GPA.
- Useful for college applications, scholarships, and academic probation checks, all of which reference GPA cutoffs.
Common GPA Calculation Methods
- Unweighted GPA (Standard 4.0 Scale): Each letter grade converts to a fixed number of grade points, regardless of course difficulty.
- Weighted GPA (5.0 Scale for AP/Honors): Advanced courses award extra grade points to reflect their difficulty — typically an extra 1.0 point for AP/IB and 0.5 for honors.
- Cumulative GPA: Combines all semesters into one overall GPA, weighted by each semester's total credit hours.
- Percentage-to-GPA Conversion: Many schools grade on a percentage or 100-point scale and need to convert to the 4.0 scale for transcripts or applications.
Key Metrics Explained
- Quality Points: Grade points earned for a course, calculated as grade value multiplied by credit hours.
- Total Credit Hours: The sum of credit hours across all courses entered.
- Semester GPA: Your grade point average for the courses entered in this calculation.
- Grade Points: The numeric value assigned to each letter grade, such as A = 4.0 and B = 3.0.
Standard Grade Scale
| Letter | Grade Value |
|---|---|
| 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 |
| F | 0.0 |
Tips for Getting the Most from This Calculator
- Enter exact credit hours: A 4-credit lab and a 1-credit elective are not equal — accurate credit values are essential for a real GPA.
- Check your school's scale: Some schools use A+ = 4.3, or adjust +/- boundaries. The default 4.0 scale matches most U.S. institutions, but verify before submitting applications.
- Use weighted GPA carefully: Weighted GPAs above 4.0 help with class rank, but many colleges recalculate admissions GPAs on their own scale.
- Project early, plan often: Run target-GPA scenarios each semester to understand how much your next term's grades will shift your cumulative average.
- Exclude non-academic courses when required: PE, pass/fail, and audited courses often don't count toward GPA — remove them if your school instructs you to.
Frequently Asked Questions
How do I calculate my GPA by hand?
Convert each letter grade to grade points (A = 4.0, B = 3.0, etc.), multiply each by the course's credit hours, add those totals together, then divide by the total number of credit hours.
What is a good GPA?
A 3.0 (B average) is generally considered solid, a 3.5+ is competitive for many colleges, and a 3.7–4.0 is considered excellent. 'Good' varies significantly by school and program, though.
What's the difference between weighted and unweighted GPA?
Unweighted GPA caps at 4.0 and treats all classes equally. Weighted GPA gives extra points for AP, IB, or honors courses, allowing GPAs above 4.0 to reflect course difficulty.
How is cumulative GPA different from semester GPA?
Semester GPA covers only the current term's courses. Cumulative GPA averages every completed semester together, weighted by each semester's total credit hours, giving a full academic-career picture.
Can my GPA go above 4.0?
Only on a weighted scale that awards bonus points for advanced coursework. On a standard unweighted 4.0 scale, 4.0 is the maximum possible GPA.
Do colleges recalculate my GPA?
Many colleges recalculate applicants' GPAs using their own standardized scale, often excluding non-academic classes (like PE) or adjusting weighting for AP/honors courses, so your reported high school GPA may differ from what's used in admissions decisions.
How many credits do I need for my GPA to change significantly?
Because cumulative GPA is credit-weighted, the more total credits you've already completed, the less impact new courses have. Early in a program, a single semester can shift your GPA substantially; later on, it takes many more credits to move the needle.
Does a pass/fail class affect my GPA?
Typically no — most institutions exclude pass/fail courses from GPA calculations entirely, though the credits may still count toward graduation requirements.
