What This GPA Calculator Does
GPA is a grade point average: a single number that summarises how your grades translate into academic credit. A plain average is useful for a quick sense of performance, but most schools calculate GPA by weighting each course by its credit hours. That means a four-credit laboratory course usually has more influence than a one-credit seminar. This calculator supports both approaches so you can model the number your school is likely to use and still compare it with a simple average when you are planning.
The calculator has four modes. Simple mode averages letter grades without credits. Weighted mode multiplies each grade point by the credit value attached to the course. Cumulative mode works the same way across multiple terms, helping you combine past semesters with the classes you are taking now. Target mode reverses the calculation: it estimates the future GPA you would need to reach a chosen cumulative goal after a known number of future credits.
Because grading policies vary, the scale selector includes common 4.0, 4.3, 5.0 honours/AP, and 7.0 university scales. Treat the results as planning estimates, then check your institution's handbook for rules about repeated courses, withdrawals, pass/fail classes, transfer credit, plus/minus grades, and whether an A+ is capped at 4.0 or awarded extra value.
How to Use the Calculator
- Choose the GPA scale that most closely matches your school. If your transcript uses the standard US scale, start with "Standard 4.0 scale".
- Select a calculation mode. Use Simple for a quick class average, Weighted for a term GPA with credits, Cumulative for several semesters, or Target when you know where you want your cumulative GPA to land.
- Enter each course name, letter grade, and credit value. Course names are optional, but using them makes copied results and saved local history easier to read.
- Review the result and the explanation below it. The detail line shows whether the calculator averaged grades, totalled quality points, or computed the future GPA required for a target.
- Use Copy or Share if you want to send an estimate to an adviser, parent, study partner, or scholarship office. The calculator does not upload your grades; copied results leave your device only when you choose to share them.
Real GPA Examples
| Scenario | Inputs | Result | Why it matters |
|---|---|---|---|
| Three-course weighted term | English A, 3 credits; Calculus B+, 4 credits; Biology A-, 3 credits on a 4.0 scale | About 3.64 | The 4-credit B+ pulls more weight than either 3-credit course, so the result differs from a simple letter average. |
| Simple class average | A, B+, A- with no credit weighting | About 3.67 | This is useful for quick comparison, but it may not match an official transcript if credits vary. |
| Cumulative update | Current 3.20 GPA over 45 completed credits plus a 3.80 term over 15 credits | New cumulative GPA about 3.35 | A strong term improves the total, but older credits keep the cumulative average from moving all at once. |
| Target planning | Current 3.20 GPA, 45 completed credits, 15 future credits, target 3.50 | Required future GPA about 4.40 | On a 4.0 scale this target is not reachable in only 15 credits, so the student may need more credits or a different goal. |
Common Use Cases
Scholarship Planning
Many awards require a minimum GPA. Target mode helps you see whether the next term can realistically protect that threshold, especially when one poor grade has already affected your cumulative record.
Adviser Conversations
Bring a clear estimate to a meeting instead of a vague concern. The copied result shows the grades, scale, credits, and target assumption you used, which makes the discussion more specific.

GPA Calculator FAQ
Do universities use the same GPA scale?
No. Many US schools use a 4.0 scale, some use a 4.3 scale, many high schools use a 5.0 weighted scale for honours or AP courses, and some universities outside the US use 7.0 or other systems. Always choose the scale that matches your official grading policy.
What is the difference between simple and weighted GPA?
Simple GPA gives every grade equal weight. Weighted GPA accounts for credit hours, so a 4-credit class affects GPA more than a 1-credit class. Transcripts usually use a credit-weighted method.
How do I calculate cumulative GPA?
Use Cumulative mode and enter each term or course with its credit value. The formula is total quality points divided by total attempted credits. If you already know your current GPA and credits, Target mode can model future credits against that existing record.
Why does my target GPA look impossible?
If the required future GPA is higher than the selected scale allows, the target cannot be reached with the number of future credits entered. Try adding more future credits, lowering the target, or checking whether repeated-course rules can replace older grades at your school.
Should I include pass/fail courses?
Only include pass/fail courses if your school converts them into grade points. Many institutions award credit for a pass without adding quality points, which means the course may not affect GPA even though it counts towards graduation.
How are repeated courses handled?
Policies differ. Some schools average both attempts, some replace the old grade, and some keep both attempts on the transcript but use only the newer grade in GPA. Use the method described by your registrar when entering repeat courses.
Can I use percentage grades?
This calculator accepts letter grades because percentage-to-letter cut-offs vary by course and institution. Convert each percentage to the official letter grade first, then enter the letter and credit value here.
Does this calculator store my grades online?
No account is required and calculations run in your browser. Recent calculations and saved inputs may be stored in localStorage on your own device so the page can remember your work between visits.
Can this calculator match my university exactly?
It can match many common policies, but official rules can include custom grade points, course exclusions, incomplete grades, transfer-credit limits, and programme-specific requirements. Use it for planning and confirm important decisions with your school.
Is a higher weighted GPA always better?
A higher weighted GPA can reflect strong performance in rigorous courses, but admissions teams and scholarship committees often review course difficulty, trend, context, and requirements alongside the number itself.
