How GPA Is Calculated
GPA (Grade Point Average) measures academic performance on a 4.0 scale by weighting each course grade by its credit hours.
- Each letter grade has a point value: A=4.0, A-=3.7, B+=3.3, etc.
- Multiply grade points by the course's credit hours
- Sum all weighted grade points, then divide by total credits
- For cumulative GPA: combine previous grade points with new semester
Example: English (3 credits, A=4.0) + Math (4 credits, B=3.0) = (12 + 12) ÷ 7 = 3.43 GPA
Tips & Considerations
- Double-check your current gpa before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both semester gpa and cumulative gpa — they work together to give you the full picture.

- If you're unsure about your credits earned, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How do you calculate GPA?
For each course, multiply grade points (A=4.0, B=3.0, etc.) by credit hours. Sum all the products and divide by total credit hours. Example: A 3-credit A and a 4-credit B = (12+12) / 7 = 3.43.
What is a good GPA?
3.0+ (B average) is considered good. 3.5+ is very good and typically makes Dean's List. 3.7+ is excellent. For graduate school, most programs expect 3.0 or higher.
What GPA is cum laude?
Common thresholds: Cum Laude 3.5-3.69, Magna Cum Laude 3.7-3.89, Summa Cum Laude 3.9-4.0. Requirements vary by school, so check your institution's specific thresholds.
How do plus and minus grades affect GPA?
Plus adds 0.3 (B+ = 3.3), minus subtracts 0.3 (B- = 2.7). Most schools cap A+ at 4.0. This means an A- (3.7) in a 4-credit course costs 1.2 grade points compared to an A (4.0).
How do you calculate cumulative GPA?
Multiply prior GPA by prior credits to get existing grade points. Add new semester grade points. Divide the total by all credits. Example: 3.5 GPA × 60 credits = 210 points + new semester points ÷ total credits.
Do all colleges use a 4.0 scale?
Most US colleges use a 4.0 scale. Some high schools use a 5.0 weighted scale for AP/honors. Some schools only use whole grades (no plus/minus). International systems vary widely.
