Add your subjects, then press Calculate GPA to see your result.
Enter your courses, credit hours, and grades into the calculator above and get your GPA in seconds. Below, you'll find the exact formula behind the numbers, a full worked example, and answers to the questions students ask most about how GPA actually works.
A GPA calculator is a tool that turns your letter grades and credit hours into a single number: your Grade Point Average. Instead of doing the multiplication and division by hand for every course, you enter your grades once and get an accurate result immediately.
GPA itself is a weighted average, not a simple one. A course worth four credit hours affects your overall average more than a course worth one credit hour, because it represents a bigger share of your total workload. That's the part most students get wrong when they try to estimate their GPA in their head.
You could calculate GPA by hand, but a calculator removes the room for error and saves you time, especially if you're checking multiple scenarios. Here's when it's genuinely useful:
Add each course you're taking, along with its credit hours and the letter grade you earned or expect to earn. The calculator converts each letter grade to its grade point value, multiplies it by the credit hours, and adds those results together across all your courses. That total is then divided by your total credit hours to produce your GPA.
You can add or remove courses freely, which makes it easy to test a "what-if" scenario, like seeing how your GPA would change if a specific grade came in higher or lower than expected.
The formula behind every GPA calculation, including this one, comes down to two steps.
Quality Points = Credit Hours × Grade Point Value
GPA = Total Quality Points ÷ Total Credit Hours
Here's the standard 4.0-scale grade point chart used in the formula:
| Letter Grade | Percentage | Grade Point Value |
|---|---|---|
| A+ / A | 93–100% | 4.00 |
| A- | 90–92% | 3.70 |
| B+ | 87–89% | 3.30 |
| B | 83–86% | 3.00 |
| B- | 80–82% | 2.70 |
| C+ | 77–79% | 2.30 |
| C | 73–76% | 2.00 |
| C- | 70–72% | 1.70 |
| D | 60–69% | 1.00 |
| F | Below 60% | 0.00 |
Grading scales vary by school. Confirm the exact ranges your institution uses if your calculated GPA doesn't match your transcript.
Say a student took four courses in one semester. Here's the full breakdown, exactly as the calculator above would compute it:
| Course | Credit Hours | Grade | Grade Point Value | Quality Points |
|---|---|---|---|---|
| Calculus I | 4 | A | 4.00 | 16.00 |
| English Composition | 3 | B+ | 3.30 | 9.90 |
| Introduction to Psychology | 3 | A- | 3.70 | 11.10 |
| General Chemistry Lab | 1 | B | 3.00 | 3.00 |
Total credit hours: 11
Total quality points: 40.00
GPA = 40.00 ÷ 11 = 3.64
Notice that a simple average of the four grade point values — (4.00 + 3.30 + 3.70 + 3.00) ÷ 4 — would give 3.50, which is close but not identical to the correct weighted result. The gap gets bigger as your credit hours vary more from course to course.
If you're in high school, you may see two different GPA numbers on your transcript. An unweighted GPA scores every class on the same 4.0 scale, regardless of difficulty. A weighted GPA gives extra credit for harder classes, extending the scale up to 5.0.
| Course Type | "A" Grade Value | "B" Grade Value |
|---|---|---|
| Standard course | 4.00 | 3.00 |
| Honors course | 4.50 | 3.50 |
| AP / IB course | 5.00 | 4.00 |
If your school reports both, check which one a college or scholarship is asking for before you submit an application. They're not interchangeable, and using the wrong one can misrepresent your standing.
Adding up your grade points and dividing by the number of courses ignores credit hours. A 1-credit elective and a 4-credit core class don't carry the same weight in your GPA.
Some students type in a raw score like 88 instead of converting it to a grade point value first. Always convert to the 4.0 scale before running the calculation.
If you're calculating a projected GPA, don't forget to include in-progress courses using your expected grade — otherwise the number won't reflect your real standing.
A single semester's GPA only covers that term. If you want your overall academic record across every semester, you need CGPA, not GPA.
Not every school uses the same cutoffs for A, B, and C. Confirm the exact percentage ranges your institution uses before entering grades.
Pull your grades and credit hours from your actual transcript or grade portal. A rough guess can throw off the final number more than you'd expect.
If you're deciding how much a final exam matters, calculate your GPA with a few different grade scenarios to see how much room you have.
Checking your GPA regularly, rather than waiting for your transcript to update, gives you time to fix a problem while it's still fixable.
The questions students ask most often about calculating and understanding GPA.
Multiply each course's credit hours by its grade point value to get quality points, add up the quality points for all your courses, then divide by your total credit hours. That final number, usually shown to two decimal places, is your GPA.
A GPA of 3.5 or higher is generally considered strong and meets the requirements for most scholarships and honors programs. A 3.0–3.5 is solid and competitive for most jobs and graduate programs, while anything below 3.0 may limit some options.
GPA measures your performance in one semester or term. CGPA (Cumulative GPA) combines every semester you've completed into one running average. Use our CGPA Calculator if you need your full academic record instead of a single term.
Yes. If your school uses a weighted scale for AP, IB, or Honors courses, just enter the weighted grade point value for those classes (typically up to 5.0) instead of the standard 4.0 value.
Convert your grades to their nearest 4.0-scale equivalent first, using your school's official conversion chart, then enter those values. Scales vary enough between institutions that there's no single universal conversion.
Credit hours act as a weight. A 4-credit course affects your GPA more than a 1-credit course because you multiply each grade point value by its credit hours before adding everything together and dividing by total credits.
Usually not. Pass/Fail or Satisfactory/Unsatisfactory courses typically don't carry a grade point value, so they're excluded from both your quality points total and your credit hours total in the GPA formula.
It depends on the course's credit hours and how many total credits you've completed. A low grade in a high-credit class, or during an early semester when you have fewer total credits, will move your GPA more than a low grade in a light course later on.
This calculator is built for a single semester. For your full academic history across multiple semesters, use our CGPA Calculator, which combines semester GPAs and credit hours into one cumulative number.
Standard mathematical rounding applies — most schools round to two decimal places using normal rounding rules, not always rounding up. Check your registrar's specific policy if you're right on the edge of a cutoff.
Requirements vary widely by program, but many graduate programs look for a 3.0 or higher, with more competitive programs expecting 3.5 or above. Always check the specific program's admissions page for their stated minimum.
Not on a standard unweighted scale, where 4.0 is the maximum. On a weighted scale that gives extra credit for AP, IB, or Honors courses, GPAs can go above 4.0, sometimes up to 5.0.
GPA comes down to two numbers per course — credit hours and grade points — multiplied together, added up, and divided by your total credit hours. The calculator above does that math instantly, but understanding the formula behind it means you can catch an error on your transcript or plan ahead before your next semester starts.
If you need your overall academic record across multiple semesters rather than just one term, the CGPA Calculator picks up right where this one leaves off.
