College GPA Calculator
Calculate your cumulative college GPA with new semester grades. See how your new grades will impact your overall GPA.
Cumulative GPA is a credit-weighted average, not a simple average of grades, which is why Credits Completed matters as much as Current GPA itself: your prior GPA is first converted back into Quality Points (Current GPA times Credits Completed) so it can be combined on equal footing with this semester's new quality points, and only then divided by the new Total Credits. The direction each new grade pulls Cumulative GPA depends only on whether that grade's point value is above or below your current average -- A (4.0) and B (3.0) credits pull a below-average GPA up, while C, D, and F credits pull an above-average GPA down; Cumulative GPA can never exceed 4.0 only because 4.0 is the highest grade point value available, not because new credits can only ever help. New Credits at an A (4.0) raise Cumulative GPA for any Current GPA below 4.0, and leave it unchanged only in the edge case where Current GPA is already a perfect 4.0. New Credits at an F (0.0) work the same way in reverse for the common case (Current GPA above 0.0): they lower Cumulative GPA. Semester GPA is calculated independently from Cumulative GPA -- it only reflects this term's new credits and grades, with no contribution from Current GPA or Credits Completed at all, which is why a strong single semester can show a high Semester GPA even when it barely moves a large, already-established Cumulative GPA. This calculator uses whole-letter grade points only (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0); it has no +/- buckets, so a +/- grade should be entered in its nearest whole-letter bucket and the result treated as an estimate.

How to Use This Calculator
- Enter your Current GPA (0–4.0 scale) and the total Credits Completed so far.
- Fill in 'New Credits — A', 'New Credits — B', and 'New Credits — C' with the credit hours you earned at each grade this semester.
- For D or F grades, expand the Advanced section and add those credits as well.
- The calculator shows your updated Cumulative GPA, this semester's GPA, and how much your GPA changed.
- Consult the Credits Needed to Reach GPA Target table to plan future semesters.

Frequently Asked Questions
Why does Credits Completed matter if I'm only entering new grades this semester?
Cumulative GPA is a weighted average, so your existing Credits Completed determines how much "weight" your Current GPA carries against the new semester's grades. A student with 90 completed credits and a 3.0 GPA needs a much stronger new semester to move their Cumulative GPA than a student with only 10 completed credits at the same 3.0, because the new credits are a smaller share of the larger total.
Will adding New Credits — A always raise my Cumulative GPA?
Yes, across the full 0-30 credit range, with one edge case: if your Current GPA is already a perfect 4.0, adding A grades leaves Cumulative GPA unchanged rather than raising it further, since 4.0 is the top of the scale and there's no higher grade point value to pull the average up. For any Current GPA below 4.0, more A credits always raise the cumulative result.
How is Semester GPA different from Cumulative GPA?
Semester GPA is calculated only from the New Credits and grades you enter for this term -- it ignores Current GPA and Credits Completed entirely. Cumulative GPA instead blends this semester's results into your full academic history. A single outstanding semester can post a high Semester GPA while barely moving an already large Cumulative GPA built on many more prior credits.
What does the Credits Needed to Reach GPA Target table assume?
It assumes every future credit hour is earned at a straight 4.0 (an A), the fastest mathematically possible path to each target GPA, and calculates the minimum whole number of additional A credits needed on top of your Cumulative GPA and Total Credits (which already include the New Credits you entered above) to reach 2.0, 2.5, 3.0, and 3.5. It shows "N/A" for the 4.0 target itself, since reaching a perfect 4.0 cumulative average is only possible if your GPA is already there.
Does this calculator handle +/- grades like A- or B+?
No -- it only accepts whole-letter grade buckets (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0). Most US colleges actually grade on a +/- scale (A- = 3.7, B+ = 3.3, and so on), so if your school uses one, enter each +/- grade in its nearest whole-letter bucket (A- as A, B+ as B) and treat the result as a close estimate rather than an exact figure -- the gap between the true GPA and the bucketed estimate grows with more +/- grades mixed together.
