How to Calculate
GPA

Add your courses, credits, and grades โ€” your cumulative GPA on the 4.0 scale calculates instantly.

The GPA Formula

GPA = ฮฃ (Grade Points ร— Credits) รท ฮฃ Credits

Multiply each course's grade points by its credit hours, sum all products, then divide by total credit hours.

๐Ÿ’ก Example: A (4.0) in 3-credit Math = 12 quality points. B (3.0) in 4-credit English = 12 quality points. GPA = (12+12) รท (3+4) = 24 รท 7 = 3.43

Step-by-Step Guide

1

List all your courses

Include the course name, credit hours (usually 3โ€“4 per course), and your letter grade for each.

2

Convert grades to grade points

A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Pluses add 0.3, minuses subtract 0.3 (e.g. B+ = 3.3)

3

Calculate quality points per course

Multiply grade points ร— credits. A in 3-credit course = 4.0 ร— 3 = 12 quality points.

4

Divide total quality points by total credits

GPA = Total Quality Points รท Total Credits. If sum = 48 and total credits = 15, GPA = 3.20

Worked Examples

Semester A

Math A (3cr): 12pts
Eng B+ (4cr): 13.2pts
Bio B (3cr): 9pts
GPA = 34.2/10 = 3.42

Dean's List

4 courses ร— 3cr = 12cr
All A grades = 48 qpts
48 รท 12
GPA = 4.00 โœจ

Mixed Semester

A (3), B (4), C (3), D (2)
= 12+12+6+2 = 32pts
รท (3+4+3+2) = 12cr
GPA = 2.67

Recover from F

F in 3cr course = 0pts
Need A in 3cr course
= +12pts

Frequently Asked Questions

What is a good GPA? โ–พ
For college: 3.5โ€“4.0 is excellent (Dean's List territory), 3.0โ€“3.49 is good, 2.5โ€“2.99 is average, below 2.0 may put you on academic probation. For graduate school applications, most programs want 3.0 minimum, competitive ones want 3.5+.
How does one bad grade affect my GPA? โ–พ
One F in a 3-credit course at the end of a 30-credit program with a 3.5 GPA would drop you to about 3.2. The more credits you've earned, the harder it is for one course to dramatically change your GPA โ€” in both directions.
Is GPA calculated the same everywhere? โ–พ
The 4.0 scale is standard in the US. Some schools use a 5.0 scale for AP/Honors courses. Other countries use different systems โ€” UK uses First/2:1/2:2/Third, Europe often uses 1โ€“10 scales. Always check your institution's specific system.
How many courses do I need to raise my GPA? โ–พ
The more courses you've already taken, the more A's you need. If you have 90 credits and a 2.8 GPA, earning a 4.0 in 30 more credits would raise you to about 3.05. Use our calculator to experiment with different scenarios.
