Use the scientific calculator with steps
The formula, worked through
GPA = Σ(pointsᵢ × creditsᵢ) ÷ Σcreditsᵢ
points = grade points (A=4, B=3, …) · credits = course credit hours
- An A (4.0) in a 3-credit course contributes 4 × 3 = 12 quality points.
- A B (3.0) in a 4-credit course contributes 3 × 4 = 12; another A in a 3-credit course adds 12 more.
- Total quality points 36 ÷ total credits 10 = 3.60 GPA.
- Weighted GPAs scale honors or AP courses differently; check your school before comparing.
- 0
- A (3 cr), B (4 cr), A (3 cr)
Result 3.60 cumulative GPA
When to use this calculator
- Plan a semester Add each course with its credit value and grade, then check whether the result uses the grading scale your school expects.
- Check a target GPA Use the target and remaining-credit fields when available to estimate the average needed in future courses.
- What moves the gpa number The gpa result is only as good as the inputs: change one field at a time and watch which figures shift before you commit to a decision.
Enter grades and credits
Enter grade points and the credit value for each course. A weighted GPA gives a larger course more influence when it has more credits. Use the grading scale required by your school and keep plus or minus conversions consistent.
GPA formula
GPA equals total grade points multiplied by course credits, divided by total credits. An unweighted average treats each course as one equal item. The result is an estimate when a school uses a custom scale, quality-point rule, or separate semester weighting.
Worked example
A 4.0 grade for 3 credits and a 3.0 grade for 3 credits produce a weighted GPA of 3.5. Add all courses before rounding if your school publishes a specific rounding rule.
Frequently Asked Questions about GPA Calculator
Which grading scale should I choose?
Choose the scale that matches your school or report. Percentage, letter, and 4-point systems can produce different grade-point values.
Is this an official academic GPA?
It is an estimate based on the courses, credits, and scale you enter. Confirm the official GPA with your school because policies and weighting can differ.
How do I sanity-check the gpa result?
Rerun the calculator with a known example and compare it against the figure you expect; then swap back to your own numbers.
Which gpa inputs change the outcome most?
Adjust one field at a time. The figure that shifts the result hardest is the assumption worth double-checking before you rely on it.
What GPA is two A's and one B?
With 3-credit A courses and a 4-credit B, the GPA is 3.60. If all three courses carry equal credits, the same grades give 3.33.
Is a 3.5 GPA good?
A 3.5 sits above the roughly 3.0 national average in the US and keeps most graduate and scholarship applications competitive, though selective programs screen higher.
