What does unweighted high school GPA mean?
An unweighted GPA uses the same base grade-point value for a grade regardless of course difficulty. In a common four-point model, A is 4 points, B is 3, C is 2, D is 1, and F is 0, with plus/minus values between those whole-grade steps.
For a general credit-weighted 4.0 calculation, you can also compare the same courses in the GPA Calculator.

How course credits affect high school GPA
This calculator weights each grade by course credit. A full-credit class therefore has more influence than a half-credit class. The result is total grade points divided by the total credits for rows you entered.
If you are planning how many classes remain toward a credit target, use the Credit Hours Calculator alongside your GPA estimate.
What about honors, AP or IB classes?
Some schools add extra points for advanced classes, but those systems differ. Because this page is intentionally unweighted, it does not add course-level bonuses. Use the Weighted GPA Calculator when you need a bonus system that can be configured.
For honors, AP, IB or other advanced-course bonuses, switch to the Weighted GPA Calculator and match your school's policy.
Use the school transcript as the source of truth
Districts and schools may define letter-grade cutoffs, credit values, repeated-course policies and weighting differently. Use this calculator to understand the arithmetic, but use your official transcript or counseling office for the GPA reported by your school.
If you need to know what score is required on a remaining exam, the Final Grade Calculator handles that separate question.
Worked example: High School GPA
Enter the following values in the High School GPA Calculator and calculate to reproduce this result.
- Course 1: English Composition
- Grade (entry 1): A+
- Credits (entry 1): 3
- Course 2: English Composition
- Grade (entry 2): A+
- Credits (entry 2): 3
- Course 3: English Composition
- Grade (entry 3): A+
- Credits (entry 3): 3
- Course 4: English Composition
- Grade (entry 4): A+
- Credits (entry 4): 3
- Course 5: English Composition
- Grade (entry 5): A+
- Credits (entry 5): 3
Example result: 4. The entered classes produce an estimated unweighted GPA of 4.
Calculation used: Unweighted GPA = Σ(grade points × course credits) ÷ Σ(course credits)
How to interpret this example
The example uses the grade-point rules selected on this page. Schools may use different credit weights, plus/minus grades or course-level bonuses. Treat the result as an estimate until it matches the school’s published transcript policy.
