What the result explains
What This Calculator Provides
Add each course, its credit hours, and a letter grade to calculate a credit-weighted GPA on a common 4.0 scale, a 4.3 scale, or grade points you enter yourself. Courses with more credits contribute more to the average. Course names help organize the rows but do not affect the math. This page does not infer honors, AP, repeated-course, pass/fail, transfer-credit, or institution-specific rules; use the scale and transcript policy published by your school for an official result.
- credit-weighted semester GPA
- new cumulative GPA when a previous record is entered

Method
Formula and Calculation Method
Credit-weighted GPA formula
GPA = Σ(credit hours × grade points) ÷ Σ(credit hours)
- Multiply each course’s credits by the selected letter-grade points.
- Add those quality points.
- Divide by total included credits.
An unweighted average of course grades would give every course equal influence. This calculator weights by entered credits.
Worked from input to answer
Worked Examples
Four-credit A and three-credit B
- 4 credits × 4.0 = 16 grade points
- 3 credits × 3.0 = 9 grade points
- Total = 25 points ÷ 7 credits
Result: GPA = 3.57.
Why credits matter
- A four-credit course contributes twice the weight of a two-credit course.
- The same letter-grade change therefore moves the GPA more in the higher-credit course.
Result: Credit weighting reflects course load, but only if the institution uses the same credits and grade-point scale.
Around the Grade Point Average
Institutions move between grade points and percentages freely, and the percentage calculator covers the conversion as well as any weighted average outside the 4.0 scale.
The rest of a term runs on dates and word limits: measure the length of the term or the days to a deadline and check an essay against its word limit before submitting.

Weighted can mean two different things
This calculator is credit-weighted: a course with more credits counts more. Some schools also call a GPA “weighted” when honors or advanced courses can exceed 4.0. That additional course-level weighting is not applied here.
Institution rules vary
Schools differ on plus/minus grades, repeated courses, withdrawals, pass/fail work, transferred credits, rounding, and cumulative GPA. Compare the displayed mapping and included courses with your institution’s official policy.
Practical Uses
- Estimating a term GPA before grades post
- Checking how a high-credit course affects the average
- Recalculating after adding or removing a course
- Understanding total quality points
Assumptions
- The displayed letter-grade mapping applies.
- Every entered course should be included in the GPA.
- Credit hours are positive and represent the institution’s weighting.
Important Limitations
- No honors/AP bonus points or scales above 4.0 are applied.
- Repeated-course, pass/fail, withdrawal, and transfer policies are not modeled.
- The estimate is not an official transcript GPA.

Frequently Asked Questions
Quick answers to common questions about the GPA calculator.
How is GPA calculated?
Multiply each course’s grade points by its credit hours, add those results, and divide by the total credits. A 4-credit A at 4.0 contributes 16 grade points; a 3-credit B+ at 3.3 contributes 9.9. Together that is 25.9 ÷ 7 = 3.70.
What is a good GPA?
There is no single answer. Programs, scholarships, honours thresholds, and employers set their own bars, and a 3.5 can be routine in one department and exceptional in another. Compare against the requirement you are actually trying to meet rather than a general figure.
What is the difference between semester GPA and cumulative GPA?
A semester GPA covers one term. A cumulative GPA covers every credit on your record. Switch to Cumulative GPA and enter your current GPA and completed credits to combine the two.
Does GPA depend on credit hours?
Yes. The average is credit-weighted, so an A in a four-credit course contributes twice the grade points of an A in a two-credit course.
Is A+ always worth 4.0?
No. Many schools cap every A-range grade at 4.0, while others award 4.3 for an A+. Choose the 4.3 scale or enter custom values to match your institution.
Why does my university GPA differ from this calculator?
Institutions differ on plus/minus values, repeated courses, withdrawals, pass/fail work, transferred credits, honours weighting, and rounding. This page applies only the scale shown and the courses you enter.
Can I calculate GPA using a custom grading scale?
Yes. Choose Custom under Grading scale and edit any grade’s point value. The result, the per-course grade points, and the reference table all follow your values.
How do repeated courses affect GPA?
That depends entirely on your school. Some replace the original grade, some average both attempts, and some count both. This calculator has no repeat rule: include or exclude the attempt yourself to match your institution’s policy.
