Your GPA follows you from your first transcript to graduate-school applications and your first job. Enter your courses, credit hours, and letter grades below to see your GPA on the 4.0 scale — the same weighted-average math your registrar uses.
What is GPA?
GPA stands for Grade Point Average. It is a single number — usually between 0.0 and 4.0 — that summarises every grade on your transcript, weighted by how many credit hours each course is worth.
The system exists so universities can compare students fairly even when they take very different classes. A higher GPA signals a stronger overall record.
In the US, the standard scale runs A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus and minus grades adjust by 0.3 or 0.7 — so an A- is 3.7 and a B+ is 3.3.
Your GPA shows up on every transcript. Graduate schools, scholarship boards, and most employers look at it. Many internships set a minimum GPA before they will read the rest of your application — which is why it pays to know yours at any moment.
How GPA is calculated
GPA uses one weighted-average formula. Credit hours act as weights, so a 4-credit class affects your GPA more than a 1-credit class with the same grade.
GPA = Total Quality Points ÷ Total Credit Hours
- Convert each letter grade to its point value (A = 4.0, B = 3.0, and so on).
- Multiply the grade points by the course's credit hours — that gives the quality points for that course.
- Add the quality points across every course, then divide by total credit hours.
How to use this calculator
The math happens automatically. Four steps:
-
01
Add a row for each course
Type the course name or leave it blank — only credit hours and grade are required.
-
02
Enter the credit hours
Usually 1, 2, 3, or 4. The value is at the top of your syllabus or on your transcript.
-
03
Choose the letter grade
Pick from the dropdown — the calculator converts it to a point value automatically.
-
04
Read your live GPA
The result updates the moment any input changes. No submit button needed.
Worked example: one semester, four classes
A typical 11-credit semester with mixed grades:
| Course | Credits | Grade | Quality Points |
|---|---|---|---|
| Calculus I | 4 | A (4.0) | 16.0 |
| English Composition | 3 | B+ (3.3) | 9.9 |
| Intro Psychology | 3 | B (3.0) | 9.0 |
| Physical Education | 1 | A (4.0) | 4.0 |
Total quality points: 38.9 ÷ total credits: 11 = 3.54 GPA. That single number is what shows up on your transcript at the end of the term.
Why use this calculator instead of doing it by hand
Working out a GPA by hand is not difficult, but it is easy to make small mistakes — multiplying by the wrong credit value, confusing A- with 4.0 instead of 3.7, forgetting a course. Each slip can shift the final number by a tenth or two.
Reasons students reach for this tool: it uses the same weighted-average formula your registrar uses (the result matches your transcript within rounding); every input updates the GPA live; nothing is stored or sent to a server (the calculation runs entirely in your browser); and you can add hypothetical future courses to see exactly how a planned grade would change your GPA.
For most students it is a 30-second job — and worth doing properly when the result feeds into scholarship eligibility, dean's list standing, or graduate-school cut-offs.
Tips to improve your GPA
- Prioritise high-credit courses. A 4-credit A counts four times more than a 1-credit A — put your best effort into the heaviest classes on your schedule.
- Use office hours early. Most grade trouble starts around week three, not finals week. A short conversation with your professor in week four prevents the panic email in week fourteen.
- Retake low grades if your school offers grade replacement. Replacing a D with a B can move your GPA more than an entire new semester of courses, especially in a high-credit class.
- Watch the weighted average. Lighter elective semesters look attractive but barely move the needle — one demanding semester with strong grades shifts your GPA more than three light ones.
- Recalculate after every term so you always know where you stand against your scholarship, honours, or graduate-school target.
Frequently Asked Questions
Quick answers about the GPA Calculator — how it works, what it counts, and how to read your result.
The standard US 4.0 scale: 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. If your school uses a 4.3 scale or a weighted scale, switch to the matching country-specific or weighted calculator.
Small gaps (0.01-0.02) are normal — schools round differently. A bigger gap usually means a missing course, the wrong credit value, or a grade entered with the wrong point value (treating A- as 4.0 instead of 3.7 is the most common). Double-check each row against your transcript.
Yes — the formula is the same. The difference is credit values: high school classes are typically 1.0 credit each, while college courses range from 1 to 5. Enter whatever your transcript shows. For weighted GPAs with AP or honors bonuses, use the Weighted GPA Calculator instead.
No. Everything runs in your browser and disappears the moment you close the tab. There is no signup, no account, and no tracking of your inputs. If you want to keep a record, copy the result somewhere — the calculator does not have a save feature.
Most schools exclude both from the GPA. A W (withdrawal) typically counts toward attempted credits but contributes no grade points. Pass/fail grades usually do not affect the GPA at all. Leave them out of the calculator unless your school's specific policy says otherwise — check your academic handbook.
