What do credits mean in GPA?
Credits are the weight in this calculation. A 4-credit course influences GPA four times as much as a 1-credit course with the same grade-point value.

GPA Calculator
Calculate a credit-weighted semester GPA, then optionally combine it with your current cumulative GPA. Review the credits, quality points, and editable grade scale behind the result.
Courses and grades stay in this browser page. This estimate is not an official school record.

How GPA is calculated with credits
This calculator treats credits as weights. A course worth more GPA credits has more influence because its grade points are multiplied by more credits before the average is calculated.
quality points = grade points × course creditssemester GPA = total quality points ÷ total GPA-counted creditsCumulative GPA adds prior quality points—current cumulative GPA × completed GPA credits—to this semester before dividing by the combined GPA credits.
Grade scales differ
A+, plus/minus grades, pass/fail work, repeats, withdrawals, transfer credit, and rounding rules vary by institution. Edit the scale and compare the result with your registrar's policy.
Estimate vs. official GPA
This app calculates from the values you enter. Your official transcript or registrar determines which courses and credits count and how the official GPA is rounded.
Worked examples
3.500A (4.00) × 3 credits + B (3.00) × 3 credits = 21 quality points ÷ 6 credits.
3.633A− × 3 credits + B+ × 4 credits + A × 3 credits = 36.33 quality points ÷ 10 credits.
3.308Prior 3.250 over 40 credits combined with a 3.500 semester over 12 credits.
Common mistakes
- Averaging grade points without weighting by credits.
- Using earned credits when the school uses attempted GPA credits.
- Mixing one grade scale with prior GPA calculated under another.
What this version does not do
It does not calculate weighted high-school GPA, target GPA, class rank, GPA-to-percentage conversions, or school-specific repeat policies.
Private by design
No transcript upload is required. Courses, grades, credits, grade-scale edits, and results stay in page memory and are not saved as a work history by this app.
