This GPA Calculator — also a full grade point average calculator, grade calculator, and quality points calculator in one — turns a list of courses, credit hours, and letter grades into your semester GPA on the standard 4.0 scale calculator basis, and can combine that with a previous GPA and credit total to produce your updated cumulative GPA. Whether you need a high school GPA calculator for weighted honors and AP classes, a college GPA calculator or university GPA calculator for a single term, or a simple class GPA calculator to check one course's impact, it's built for students planning a course load, checking academic standing, or figuring out what grades they need to hit a target GPA.
Each course you add gets a Quality Points value equal to its Credit Hours multiplied by its Grade Point — this is the letter grade to GPA conversion (A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0.0). Acting as a semester GPA calculator, it sums the quality points and credit hours across every course, then divides: Semester GPA = Total Quality Points ÷ Total Credit Hours, correctly weighting courses by their credit hours so GPA reflects how much each class actually counts. If you fill in a previous GPA and previous credit total, this cumulative GPA calculator recombines everything into Cumulative GPA = (Previous GPA × Previous Credits + This Semester's Quality Points) ÷ (Previous Credits + This Semester's Credits), correctly weighting older and newer coursework by how many credit hours GPA math assigns to each. See the Worked Example section further down this page for a full step-by-step walkthrough with real numbers.
GPA affects academic standing, scholarship eligibility, honor roll and Dean's List qualification, graduate school admissions, and sometimes job applications, so understanding exactly how a grade in a specific class moves the number helps with course-load planning — for example, deciding whether to retake a class, drop a course, or take on an extra credit-heavy class to offset a weaker grade. Knowing how to calculate GPA by hand also makes it easier to spot-check your official transcript.
The scale used by this calculator — the most common standard across US colleges and high schools
| Letter Grade | Grade Point | Letter Grade | Grade Point |
|---|---|---|---|
| A / A+ | 4.0 | C+ | 2.3 |
| A- | 3.7 | C | 2.0 |
| B+ | 3.3 | C- | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B- | 2.7 | D | 1.0 |
| D- | 0.7 | ||
| F | 0.0 |
Quality Points = Credit Hours × Grade Point.
Example: an A (4.0) in a 4-credit course = 16 quality points.
GPA = Total Quality Points ÷ Total Credit Hours, summed across every course this semester.
Cumulative GPA = (Previous GPA × Previous Credits + This Semester's Quality Points) ÷ (Previous Credits + This Semester's Credits).
From adding your first course to reading your cumulative GPA
Type a course name into the Course field for each class you want included — this is optional and just a label to help you read the breakdown table later; it doesn't affect the math.
Choose the letter grade you earned (or expect to earn) from the Grade dropdown, which is built on the standard 4.0 scale from A/A+ down to F.
Type the credit hours for that course into the Credits field. Because GPA is credit-weighted, this number determines how heavily the grade counts toward your final average.
Click "+ Add Course" to add a row for every class this semester. Made a mistake or want to remove one? Click the ✕ button on that row.
Optionally fill in your previous GPA and previous credit hours in the Cumulative GPA card, then click "Calculate GPA" to see your semester GPA, total credits, total quality points, cumulative GPA, and a full per-course breakdown table.
Two scenarios: a four-course semester GPA, then folding it into a cumulative GPA
Suppose a student takes four courses in one semester with the following grades and credit hours:
| Course | Credit Hours | Grade | Grade Point | Quality Points |
|---|---|---|---|---|
| College Algebra | 3 | A | 4.0 | 12.0 |
| Biology I | 4 | B | 3.0 | 12.0 |
| English Composition | 3 | B+ | 3.3 | 9.9 |
| World History | 2 | C+ | 2.3 | 4.6 |
Now say this same student already had a 3.5 GPA across 45 previous credit hours before this semester.
Explanation: Notice World History's 2 credit hours contributed less to the total than Biology I's 4 credit hours, even though the grades (C+ vs B) aren't dramatically far apart — this is the credit-weighting effect in action. You can reproduce either scenario yourself in the calculator above by entering the same courses, grades, and credit hours, plus the previous GPA and credits for scenario 2.
What your number generally signals — actual cutoffs always depend on your specific school
| GPA Range | General Standing | Common Academic Significance |
|---|---|---|
| 3.9 – 4.0 | Exceptional | Summa cum laude range at many schools; highly competitive for top scholarships and grad programs |
| 3.7 – 3.89 | Excellent | Magna cum laude range; strong Dean's List and scholarship eligibility |
| 3.5 – 3.69 | Very Good | Commonly qualifies for Dean's List / Honor Roll at many institutions |
| 3.0 – 3.49 | Good | Often meets scholarship-renewal and graduate-school baseline expectations |
| 2.5 – 2.99 | Satisfactory | Generally meets standard graduation requirements at most schools |
| 2.0 – 2.49 | Below Average | May trigger an academic-warning notice at some institutions |
| Below 2.0 | Academic Risk | Commonly the threshold many schools use for academic probation or suspension |
If your GPA is above 3.5: you're generally in strong standing for Dean's List, honors, and competitive scholarship renewal — check your specific school's published thresholds to confirm.
If your GPA is between 2.0 and 3.0: you likely meet baseline graduation requirements at most schools, but may fall short of scholarship, honors, or some graduate-admission minimums — this is a common range where students plan a course-load strategy to raise their average.
If your GPA is below 2.0: many colleges flag this range for academic warning, probation, or loss of federal financial aid eligibility under Satisfactory Academic Progress rules — contact your academic advisor promptly if you're in this range.
These bands describe common patterns across US colleges and high schools, not a universal rule — always confirm exact Dean's List, scholarship, probation, and graduation GPA thresholds against your own school's official academic policy or registrar.

What this GPA calculator does well, and where results are estimates
This calculator computes the standard unweighted 4.0 scale on the left
| Letter Grade | Unweighted (this calculator) | Typical Weighted (Honors/AP/IB) |
|---|---|---|
| A / A+ | 4.0 | 4.5 – 5.0 |
| A- | 3.7 | 4.2 – 4.7 |
| B+ | 3.3 | 3.8 – 4.3 |
| B | 3.0 | 3.5 – 4.0 |
| C+ | 2.3 | 2.8 – 3.3 |
| F | 0.0 | 0.0 |
Weighted scales vary widely by district and school, so treat the weighted column as illustrative — always confirm your school's exact weighting rules if a weighted figure matters for class rank or transcripts.
Summary: This GPA calculator gives you an instant, free, credit-weighted semester and cumulative GPA on the standard 4.0 scale — a reliable planning tool, not an official transcript. Pair it with related tools like the Percentage Calculator and Average Calculator for a fuller picture of your academic numbers.
