GPA Calculator — Weighted, Unweighted & Cumulative
Add your courses, credits and grades and get your semester GPA instantly — on a 4.0, 4.3 or 5.0 weighted scale, with AP and honours boosts, percentage grades and a running cumulative GPA all handled in one place.

Cumulative GPA update
Letter or percentage grades
Calculate your GPA
Choose a grading scale, list your courses, and add your previous GPA if you want the new cumulative figure. Nothing is uploaded or stored.
Your GPA will appear here
Enter at least one course with a grade and credit value, then hit calculate for your semester GPA, quality points and grade breakdown.
Why this calculator
Every GPA scenario in one calculator, not five different pages
Most GPA tools force you to pick a separate page for weighted, unweighted, high school, college or cumulative. This one handles all of them, keeps your rows on screen and shows the arithmetic behind the number.
Real AP and honours weighting
Mark each course as regular, honours or AP/IB and the boost is applied per course — the way schools actually calculate it, instead of a flat bump on everything.
Cumulative GPA in the same view
Enter your previous GPA and credits earned and you immediately see how this semester moves your overall average, up or down and by how much.
Unlimited courses
Add as many rows as you need, delete the ones you don’t, or drop in five at once. Nothing is capped at six courses like most calculators.
Full grade breakdown
See quality points per course, total credits and where each grade sat, so you can check the maths or work out which class is pulling the average down.
Private and instant
Runs entirely in your browser with no account, no ads over the tool and no grades sent anywhere. It works comfortably on a phone between classes.
How to use it
How to calculate your GPA in four steps
Pick your scale
Unweighted 4.0 is standard. Choose 5.0 weighted if your school gives AP and honours courses extra points.
Add your courses
Enter each course, its letter grade or percentage, and the credit hours or units it carries.
Set course levels
On the weighted scale, mark honours or AP/IB classes so the correct boost is applied to those courses only.
Add prior credits
Enter your previous GPA and credits to see the updated cumulative GPA alongside the semester result.
Benefits
Why tracking your GPA properly is worth the five minutes
Your GPA is the single number that follows you through applications, scholarships and eligibility rules — and it is far easier to protect than to repair.
Know where you stand before results day
Running the numbers yourself means no surprises when the official transcript is published.
Protect scholarship eligibility
Most merit awards and financial aid packages carry a minimum GPA condition that is checked every term.
Plan honours and Dean’s list targets
See how close you are to thresholds like 3.5 or 3.7 and how many credits it would take to get there.
Spot the course dragging you down
The per-course breakdown makes it obvious which high-credit class is costing you the most quality points.
Compare weighted and unweighted
Applications often ask for both. Switch the scale and you have each figure without recalculating by hand.
Model next semester before you enrol
Try different grade combinations to see what a heavier or lighter course load would do to your average.
The method
How GPA is calculated
The GPA formula
GPA is a credit-weighted average. Each letter grade is converted to grade points, multiplied by the credit hours for that course to give quality points, and the total quality points are divided by the total credits: GPA = total quality points ÷ total credits.
Take three courses: an A in a 4-credit class (4.0 × 4 = 16), a B+ in a 3-credit class (3.3 × 3 = 9.9) and a B in a 3-credit class (3.0 × 3 = 9). That is 34.9 quality points across 10 credits, so the GPA is 3.49.
Standard grade point values
| Letter | Percentage | 4.0 scale | 4.3 scale |
|---|---|---|---|
| A+ | 97–100 | 4.0 | 4.3 |
| A | 93–96 | 4.0 | 4.0 |
| A− | 90–92 | 3.7 | 3.7 |
| B+ | 87–89 | 3.3 | 3.3 |
| B | 83–86 | 3.0 | 3.0 |
| B− | 80–82 | 2.7 | 2.7 |
| C+ | 77–79 | 2.3 | 2.3 |
| C | 73–76 | 2.0 | 2.0 |
| C− | 70–72 | 1.7 | 1.7 |
| D | 65–69 | 1.0 | 1.0 |
| F | Below 60 | 0.0 | 0.0 |
Weighted versus unweighted GPA
An unweighted GPA caps every course at 4.0 regardless of difficulty. A weighted GPA adds points for harder classes — most commonly 0.5 for honours and 1.0 for AP or IB — so an A in an AP course scores 5.0 on a 5.0 scale. Weighted GPAs can therefore exceed 4.0, which is why a 4.3 or a 4.6 is possible at some high schools.
Colleges usually recalculate applicant GPAs on their own scale, often stripping out weighting or non-academic courses, so treat both figures as useful reference points rather than a single official number.
Cumulative GPA and how it moves
Cumulative GPA blends every credit you have taken, so its inertia grows over time. Combine your prior quality points with this semester’s and divide by the combined credits. A strong term early on shifts the average sharply; the same term in your final year barely moves it, which is why front-loading effort pays off.
What usually gets excluded
- Pass or fail courses, which earn credit without grade points at most institutions.
- Withdrawals, incompletes and audited classes.
- Transfer credits, which often count toward the degree but not the GPA.
- Repeated courses, where many schools replace rather than average the original grade.
FAQ
GPA calculator questions, answered
How do I calculate my GPA by hand?
Convert each letter grade to grade points, multiply by that course’s credit hours to get quality points, add all the quality points together and divide by the total credits. For example, 34.9 quality points across 10 credits gives a GPA of 3.49. This calculator does exactly that and shows the per-course working.
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats every course the same and tops out at 4.0. Weighted GPA gives extra points for harder classes — typically 0.5 for honours and 1.0 for AP or IB — so it can go above 4.0, usually up to 5.0. Choose the 5.0 scale in the tool and mark each course level to see your weighted figure.
How do I calculate my cumulative GPA?
Multiply your previous GPA by the credits you had already earned to get prior quality points, add this semester’s quality points, then divide by the combined total credits. Enter your previous GPA and credits in the optional section and the calculator returns the updated cumulative figure automatically.
Is a 3.5 GPA good?
On an unweighted 4.0 scale, 3.5 is generally considered strong — it usually corresponds to an A−/B+ average and meets the common Dean’s list threshold at many institutions. What counts as competitive depends heavily on the programme, so check the published ranges for the specific schools or scholarships you are targeting.
Do credit hours change my GPA?
Yes, significantly. GPA is credit-weighted, so a grade in a 4-credit course affects the average roughly four times as much as the same grade in a 1-credit course. If your school gives equal weight to every class, switch the credit weighting option to treat all courses equally.
How do percentage grades convert to GPA?
Most institutions map 93–96% to an A worth 4.0, 90–92% to an A− worth 3.7, 87–89% to a B+ worth 3.3, and so on down the scale. Select the percentage option and enter your marks directly — the tool applies the standard conversion and shows the letter equivalent it used.
Does this calculator match my school’s official GPA?
It follows the most widely used conventions, but grading policies vary. Some schools ignore plus and minus grades, use a 4.3 or 5.0 ceiling, exclude certain course types or replace repeated grades. Always treat the result as an accurate estimate and check your registrar’s published policy for the official figure.
