GPA Calculator

Formula: GPA = Total Grade Points / Total Credits

--

How this GPA calculator works

Enter the total grade points and the total credits. The calculator divides the points by the credits and shows the GPA to two decimal places. GPA = total grade points ÷ total credits.

Grade points for one course are that course’s grade multiplied by its credits. The first box is the sum of those products, not the sum of the grades alone. A grade of 9 on 4 credits contributes 36. A grade of 8 on 3 credits contributes 24. A grade of 10 on 3 credits contributes 30. The totals are 90 points and 10 credits, so the GPA is 90 ÷ 10 = 9.00.

Credits change the weight. Grades of 10 and 6 look like an average of 8 if you divide by two courses. With 4 credits and 1 credit, the points are 40 and 6. 46 ÷ 5 = 9.20, which is the figure this page returns. Equal credits are the special case where a plain average of the grades matches the GPA.

The result is always two decimal places. 200 ÷ 24 = 8.333…, shown as 8.33. 85 ÷ 16 = 5.3125, shown as 5.31. The scale is whatever you used when you built the grade points. 100 points over 10 credits is 10.00 on a 10-point scale. 29 points over 10 credits is 2.90 on a 4-point scale. Grade points must be 0 or greater, and credits must be greater than 0. Zero points over 10 credits is 0.00. An empty box, a credit total of 0, or a negative value shows --. This page does not turn the GPA into a percentage.

GPA examples

Each GPA is total grade points divided by total credits, shown to two decimal places.

How to read the result

  • Divide the two totals

    81 grade points over 10 credits is 8.10.

  • Points already include credits

    Grade × credits for each course, then add. 10 × 4 + 6 × 1 = 46.

  • Two decimal places

    7 ÷ 3 is printed as 2.33. 50 ÷ 15 is printed as 3.33.

  • Credits must be above zero

    A credit total of 0 shows --. Zero grade points over 10 credits is 0.00.

Frequently asked questions

  • How is GPA calculated on this page?

    GPA = total grade points ÷ total credits. The result is shown to two decimal places. 90 grade points over 10 credits is 9.00. 81 grade points over 10 credits is 8.10.

  • What are total grade points?

    For each course, multiply that course’s grade by its credits, then add those products. A grade of 10 on 4 credits is 40 points. A grade of 6 on 1 credit is 6 points. Together that is 46 points over 5 credits, so the GPA is 9.20.

  • Can I add the grades and divide by the number of courses?

    Only when every course has the same credits. With unequal credits the weighted sum is required. Grades 10 and 6 average to 8 if you ignore credits, but 4 credits and 1 credit make (40 + 6) ÷ 5 = 9.20.

  • Does this page use a 10-point scale or a 4-point scale?

    It uses whichever scale is already inside the grade points you type. On a 10-point scale, 100 points over 10 credits is 10.00. On a 4-point scale, 29 points over 10 credits is 2.90. The calculator does not convert between scales.

  • Why does 200 grade points over 24 credits show 8.33?

    200 ÷ 24 = 8.333…, and the page rounds to two decimal places, so it shows 8.33. 50 points over 15 credits is 3.333…, shown as 3.33. 85 points over 16 credits is 5.3125, shown as 5.31.

  • What if my grade points are zero?

    Zero grade points over a positive credit total is 0.00. Credits must be greater than 0. A credit total of 0 leaves the result as --.

  • What inputs are rejected?

    Both boxes must be filled. Grade points must be 0 or greater. Credits must be greater than 0. A negative grade-point total or a negative credit total leaves the result as --. An empty box does the same.

  • Is this the same as a percentage?

    No. The result is the GPA from the two numbers you enter. Turning a GPA into a percentage depends on the university rule, and this page does not apply one. 36 points over 4 credits is a GPA of 9.00, not a percent.

  • Is one semester a GPA and several semesters a CGPA?

    On this page both use the same division. For one semester, enter that semester’s grade points and credits. For several semesters, add every semester’s grade points into one total and every semester’s credits into one total, then divide. The page does not store earlier semesters for you.

  • Do failed or audit courses belong in the totals?

    Include a course only if it contributes grade points and credits on your mark sheet. If a fail still carries credits and a grade point, add both. If an audit has no credits, it does not change the credit total. The calculator adds only the two figures you type.
