GPA Calculator for Grade Points

Calculate a credit-weighted college GPA from course credits and grade points on a 4.0 scale, with total quality points and credits shown.

Credit-weighted grade point average

Use your institution's grade points before weighting courses by credit

A credit-weighted GPA is total quality points divided by total attempted credits. Quality points for a course equal its credit value multiplied by its grade-point value, so a four-credit course affects the result more than a one-credit course.

Grade scales are not universal. One institution may assign 3.7 to an A-minus while another uses a different value, and honors or advanced courses may add weight. Enter the grade points printed in your school's policy rather than asking this calculator to guess from letter grades.

Use only the courses that belong in the GPA you are checking. Repeated courses, withdrawals, pass/fail classes, transfer credits, and rounding can be handled differently, so compare the estimate with the registrar's official calculation.

Checks before using the result

  • Copy each course's credit hours and grade-point value from the same academic record.
  • Do not average course GPAs without weighting them by credits.
  • Check how repeated, pass/fail, honors, and transfer courses are treated.
  • Use the institution's official result for applications, eligibility, or graduation decisions.

Formula

Weighted GPA formula

Schools can use different grade scales, weighting rules, repeats, and rounding. Check your institution's official policy.

GPA = sum(credits x grade points) / total credits

Courses worth 3, 3, 4, and 2 credits with grade points 4.0, 3.7, 3.3, and 4.0 give a GPA of about 3.67.

FAQ8 common questions for this calculator.

FAQs

What grade scale does this use?+

It uses a standard 0 to 4 grade-point scale. Enter the grade points your school assigns to each course.

Why do credits matter?+

Higher-credit courses have more weight because GPA divides total quality points, credits multiplied by grade points, by total credits.

Can this calculate a semester GPA?+

Yes. Enter the credits and grade points for the courses in one semester. For cumulative GPA, include prior coursework or combine totals according to your institution's policy.

Does this convert letter grades automatically?+

No. Enter the grade-point value assigned by your school because A-minus, honors, and weighted-course values differ between institutions.

Are repeated or pass/fail courses included?+

Only if you enter them. Schools treat repeats, withdrawals, pass/fail courses, and transfer credits differently, so follow the official GPA policy.

How does the GPA Calculator calculate the result?+

For the GPA Calculator, it uses the Weighted GPA formula: GPA = sum(credits x grade points) / total credits. Courses worth 3, 3, 4, and 2 credits with grade points 4.0, 3.7, 3.3, and 4.0 give a GPA of about 3.67.

What information do I need to use the GPA Calculator?+

Enter each course's credit hours and grade-point value using your institution's scale. Include only the courses that belong in the semester or cumulative GPA you want to estimate.

How accurate is the GPA Calculator?+

The weighted GPA is exact for the credits and grade points entered. An institution's official GPA can differ because of its grade scale, repeats, pass/fail rules, transfer credits, weighting, and rounding.
