GPA Calculator: Calculate Your Grade Point Average

Convert each grade using your school’s scale

Do not assume every school maps letter grades to the same points. One school may use a 4.0 scale, while another adds grade points for advanced courses or handles plus and minus grades differently. Find the official grading policy and enter the grade points, not the percentage, unless the school explicitly maps percentages directly. For cumulative GPA, confirm whether transfer courses and repeated classes are included in the calculation.

Weight grade points by course credits

For each class, multiply grade points by credits. Add all the quality points and divide by the sum of included credits. A four-credit course should count more than a one-credit course when the policy is credit-weighted. Exclude courses that the school marks as non-GPA credit, such as some pass/fail classes, if required. Keep full precision during calculation and round only at the end using the institution’s stated rule.

Compare your result with the transcript

Use the official transcript as the source for recorded grades and credits. A semester estimate may differ from the cumulative GPA because of previous coursework, withdrawals, repeated classes, or institutional rounding. If you are checking eligibility for a scholarship or program, use the definition that program requests; some recalculate GPA from selected courses. Ask the registrar when a transcript policy is unclear instead of relying on an online estimate.

Worked example

Course A: 4.0 points × 3 credits = 12 quality points
Course B: 3.0 points × 4 credits = 12 quality points
GPA = (12 + 12) / (3 + 4) = 3.43

Do all colleges calculate GPA the same way?

No. Grade scales, credit weighting, repeated courses, and rounding policies vary. Use the grading rules published by your school.
