GPA Calculator
Last updated: 2026-06-25
Your GPA is a weighted average: the sum of (each course's grade points × credits) ÷ total credits. It is not a simple average of your grades.
Pick a grade scale (4.5 / 4.3 / 4.0), enter your courses' credits and grades, and your total credits and GPA appear instantly.

Grade-point values and rounding differ by school, so this result is a reference estimate. Use your school's official transcript for your true GPA.
How to use it
- Choose a grade scale — select your school's scale (4.5 / 4.3 / 4.0).
- Enter courses — enter each course's credits and grade. Use "Add course" to add more rows.
- View the result — click Calculate to see total credits, GPA and an approximate percentage in a table.
How GPA is calculated, with the grade point table
GPA (Grade Point Average) converts each grade you earned into grade points (a number), then takes a credit-weighted average using each course's credits. Courses worth more credits affect your GPA more. The formula is:
GPA = Σ(course grade points × course credits) ÷ Σ(course credits)
| Grade | 4.5 scale | 4.3 scale | 4.0 scale |
|---|---|---|---|
| A+ | 4.5 | 4.3 | 4.0 |
| A | 4.0 | 4.0 | 4.0 |
| B+ | 3.5 | 3.3 | 3.3 |
| B | 3.0 | 3.0 | 3.0 |
| C+ | 2.5 | 2.3 | 2.3 |
| C | 2.0 | 2.0 | 2.0 |
| D+ | 1.5 | 1.3 | 1.3 |
| D | 1.0 | 1.0 | 1.0 |
| F | 0.0 | 0.0 | 0.0 |
| P / NP | Excluded from GPA (credits only) | ||
An F is treated as 0.0 grade points and is included in your credits, dragging your average down. Pass/Fail (P/NP) courses are excluded from the GPA. To convert your GPA to a different scale or a percentage, use the grade scale converter; to turn a percentage score into a letter grade, use percentage to grade.
Frequently asked questions (FAQ)
How is GPA (grade point average) calculated?
Your GPA is the sum of (each course's grade points × its credits) divided by the total credits. For example, a 3-credit A+ (4.5) and a 2-credit B+ (3.5) give (4.5×3 + 3.5×2) ÷ 5 = 4.1. The key is that it is a credit-weighted average, not a simple average of grades.
What is the difference between the 4.5 and 4.3 scales?
The maximum scale varies by school. The 4.5 scale treats A+ as 4.5 (common at Korean universities), the 4.3 scale treats A+ as 4.3, and the 4.0 scale treats both A and A+ as 4.0. The same grade yields a different number depending on the scale, so pick your own school's scale.
Are F grades and Pass/Fail (P/NP) courses included?
An F counts as 0.0 grade points and is included in your credits, which lowers your average. Pass/Fail (P/NP) courses are usually excluded from the GPA. In this calculator, choosing a P/NP grade automatically removes that course from the average.
Will this calculator exactly match my official transcript?
This calculator uses the standard credit-weighted formula and gives a reference estimate. Schools differ in how they handle retakes, rounding and the grade-point value of each letter, so confirm your official GPA against your school's academic system (transcript).
