GPA Calculator

About this GPA Calculator

The GPA Calculator converts letter grades to grade points on a standard 4.0 scale and weights them by credit hours to find an overall grade point average. Enter one course per line to calculate a semester or cumulative GPA.

A single semester's GPA and a cumulative GPA across multiple semesters are calculated the same way, by weighting every course's grade points by its credit hours, so the only real difference is how many courses you list at once. Keeping a running list of all your past courses lets you track your cumulative GPA as new grades come in.

How the calculation works

GPA equals the sum of each course grade point multiplied by its credit hours, divided by the total credit hours. Standard grade points used: 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.

How to use it

1. Enter one course per line as grade,credits, for example A,3.
2. Use standard letter grades from A to F, with optional + or -.
3. Calculate to see the weighted GPA and total credits.

Practical example

Courses of A,3 and B+,4 and C,3 produce a GPA calculated from grade points of 4.0, 3.3 and 2.0 weighted by their credit hours.

A student who earned an A in a 4-credit course and a C in a 2-credit course has a GPA of (4.0×4 + 2.0×2) ÷ 6 = 3.33, showing how a heavier-credit course pulls the average further toward its own grade than a lighter one.

Things to double-check

Grading scales are not universal: some schools use a 4.3 scale with an A+ worth more than a standard A, some do not award plus/minus grades at all, and some weight honors or AP courses differently. Check your institution's official grading policy before relying on this tool's standard 4.0 scale for anything beyond a general estimate.

How GPA is calculated

Grade point average is the total of grade points times credits divided by the total credits. On a common 4.0 scale, A is 4.0, A minus 3.7, B plus 3.3, B 3.0 and so on. A student with an A in a 3 credit course, a B plus in a 4 credit course, a B in a 3 credit course and an A minus in a 2 credit course earns 12, 13.2, 9 and 7.4 grade points, a total of 41.6 over 12 credits, which is a GPA of about 3.47. Courses with more credits count more, so a weak grade in a large course lowers the GPA more than in a small one.

Semester and cumulative GPA

A semester GPA covers one term, and a cumulative GPA covers all terms. To combine them, use total grade points and total credits, not an average of the two GPAs, unless the credit loads were equal. If you have 60 credits at 3.2 and take 15 credits at 3.8, the new cumulative GPA is (192 plus 57) divided by 75, which is 3.32. Rules for repeated courses vary: some schools replace the old grade, others average both. Pass or fail courses are usually excluded.

Planning a target GPA

You can use the same arithmetic to plan. If your cumulative GPA is 3.2 over 60 credits and you want 3.4 after another 30 credits, you need total grade points of 3.4 times 90, which is 306, and you have 192, so the next 30 credits must earn 114, an average of 3.8. Checking this early shows whether a goal, such as a scholarship threshold, is realistic and how much each remaining course matters.

Scales differ between schools

Not every school uses this scale. Some give an A plus extra points, some use a 5.0 scale for honours courses, and many countries use percentages, classes or a 10 point scale. Some institutions do not use plus and minus grades at all. Always use the grade-point values published by your own school, and treat the calculator as an estimate. Your official transcript is the final source for scholarships and applications.

What counts as a good GPA

A good GPA depends on the school, the programme and the goal. On a 4.0 scale, 3.0 is a B average, 3.5 is often a threshold for honours or merit lists, and many scholarships ask for between 3.0 and 3.5, but each institution sets its own rule. Graduate programmes and employers may look at the GPA in your major as well as the overall figure, and a rising trend can matter as much as one weak semester. Check the published requirements of the programme you care about, and use the calculator to see what grades you need to reach them.

Worked example: one semester

A student takes five courses. Calculus is a 3 credit course with an A minus (3.7), English is 3 credits with a B (3.0), Chemistry is 4 credits with a B plus (3.3), PE is 1 credit with an A (4.0) and History is 3 credits with a C plus (2.3). The grade points are 11.1, 9.0, 13.2, 4.0 and 6.9, a total of 44.2 across 14 credits. The semester GPA is 44.2 divided by 14, which is 3.16. Notice that the single credit PE course barely moves the result, while the 4 credit chemistry grade has a bigger effect. Planning which courses to put extra effort into can help you reach a target.

Retakes, withdrawals and pass-fail courses

Each school has its own rules for special cases. Some replace the old grade with the new one when you retake a course, others average the two, and a few keep both on the transcript. If a student has 60 credits at a cumulative 2.90 and replaces a D (1.0) in a 3 credit course with a B (3.0), the grade points rise by 6, from 174 to 180, so the GPA becomes 3.00. Withdrawals usually do not count in the GPA, and pass-fail courses are often left out. Read your institution's policy and use the calculator with the same rules that your school applies.

Different scales and conversions

A 4.0 scale is common in the United States and in many universities elsewhere, but it is not universal. Some schools use a 5.0 scale for honours courses, others use percentages, classes or a 10 point scale, and the conversion between scales varies from one institution to another. Pakistani universities commonly use a 4.0 scale, but the grade-point values for each letter can differ, so use the table your own university publishes. If you apply abroad, many admissions offices ask for a transcript evaluation instead of a simple conversion, and the calculator is best used for your own tracking.

What GPA is used for, and how to improve it

Scholarships, graduate programmes, honours lists and some employers look at GPA. A higher cumulative GPA becomes harder to change as credits build up: with 90 credits at 3.0, raising the average to 3.5 would need another 90 credits of straight A grades, since (270 plus 4 times 90) divided by 180 is 3.5. Early semesters therefore matter most. To improve your GPA, focus on courses with many credits, use office hours, plan your workload, and ask the advisor about grade replacement options. Employers often care about the trend and the relevance of your courses as well as the number.

Key terms explained

Credit hours measure how much a course counts. Grade points are the number assigned to a letter grade, and quality points are the grade points multiplied by the credit hours. A semester GPA covers one term and a cumulative GPA covers all terms. A weighted GPA gives extra points to honours or advanced courses. Honours or dean's list status depends on a threshold. Academic probation may apply if the GPA falls below a minimum, and a transcript is the official record of courses and grades.

Rules of thumb and quick checks

GPA equals total quality points divided by total credit hours. On a standard scale A is 4, B is 3, C is 2, D is 1 and F is 0, with plus and minus grades in between. A 3.0 is a B average. To combine old and new results, use the old GPA times the old credits plus the new GPA times the new credits, divided by all the credits. The larger your credit base, the more slowly the GPA moves, so early semesters carry great weight.
