Cumulative GPA Calculator

Multiply your current GPA by the number of credits you have already completed to get your existing grade points. For the new semester, multiply each course's grade-point value by its credit hours and add those up. Add the two grade-point totals, then divide by the new total credits. That weighted average is your new cumulative GPA.

Credit hours weight each course's contribution to your GPA. A 4-credit class with an A pushes your GPA more than a 1-credit elective with the same A. Cumulative GPA is the credit-weighted average of every graded course on your transcript so far.

It depends on your school's policy. Some schools replace the original grade in cumulative GPA when you retake a course. Others average both attempts. This calculator simply adds the new course as a new line, so if you want to model a grade replacement, leave the original out of the completed credits or adjust the totals manually.

The standard college 4.0 scale: A+ and A are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. Some schools cap A+ at 4.33 or use slightly different cutoffs. Check your school's exact scale if it matters for borderline cases.

For high school, the credit-weighted approach in this calculator works if your school assigns credits to each class. For a simpler GPA without credits, or for weighted GPA with honors and AP bonuses, use the high school GPA calculator instead.
