Calculation Guide
How to calculate GPA accurately
A GPA is a credit-weighted average, not always a simple average of letter grades. Courses with more credit hours contribute more to the final number, which is why entering the correct credits matters as much as selecting the correct grade.
This calculator uses the common U.S. 4.0 scale with plus and minus grades. Turn on weighted GPA only when your school awards extra points for advanced courses, and always compare the result with the grading policy printed on your transcript or student handbook.
How to use the calculator
- 1
Match your grading policy
Confirm whether your school uses plus/minus grades, course credits, and weighted bonuses before entering data.
- 2
Add every GPA-bearing course
Enter the course name, credit value, letter grade, and course level. Exclude pass/fail or withdrawn courses unless your school counts them.
- 3
Review the weighted average
The result updates instantly. Use the target and prediction tools to test realistic future-grade scenarios.
GPA formula
GPA = Σ (grade points × course credits) ÷ Σ course credits
The product of grade points and credits is often called quality points. Add all quality points, then divide by all GPA-bearing credits.
Worked GPA example
Suppose a student completes three courses on an unweighted 4.0 scale:
| Course | Grade | Credits | Quality points |
|---|---|---|---|
| Biology | A (4.0) | 3 | 12.0 |
| English | B+ (3.3) | 4 | 13.2 |
| History | A− (3.7) | 2 | 7.4 |
The student earns 32.6 quality points across 9 credits: 32.6 ÷ 9 = 3.62 GPA.
Common 4.0 letter-grade conversion
| Letter grade | Grade points | Letter grade | Grade points |
|---|---|---|---|
| A / A+ | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B− | 2.7 | D / D− | 1.0 / 0.7 |
| F | 0.0 | — | — |
Before you use the result
- Schools can use different percentage cutoffs even when both report GPA on a 4.0 scale.
- Repeated courses, pass/fail grades, withdrawals, and transfer credits follow institution-specific rules.
- A weighted GPA can exceed 4.0; an unweighted GPA normally cannot.
Frequently asked questions
What is a good GPA?
Context matters. A 3.0 is commonly considered solid academic standing, while selective programs may expect substantially higher results and rigorous coursework. Compare your GPA with the published expectations for your school, major, scholarship, or target colleges.
Do all classes count toward GPA?
Usually only GPA-bearing courses count. Pass/fail, audited, withdrawn, incomplete, and transfer courses may be treated differently. Your institution’s transcript policy is the final authority.
Should I enter percentages or letter grades?
Use the final letter grade shown by your school. Percentage-to-letter cutoffs vary, so converting a percentage with a generic chart can produce a different result from your official GPA.
Can a GPA be higher than 4.0?
Yes, on a weighted scale. Schools may add points for Honors, AP, IB, or dual-enrollment courses. The maximum and bonus amounts vary by school.
Is the calculator result official?
No. It is an estimate based on the information entered and this site’s grade scale. Your registrar or school counselor determines the official GPA.
