GPA Calculator (4.0 Scale)

Calculate your credit-weighted GPA on the standard US 4.0 scale from letter grades and credits.

GPA (4.0 scale)

3.36

Credits counted

Step-by-step working

Points: A(4)×3 + B+(3.3)×4 + A-(3.7)×3 + C(2)×2
GPA = Σ(points × credits) / Σ credits = 3.36

Mathematical Formula

GPA = Σ(grade points × credits) / Σ credits; A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7, F = 0.

Overview & Explanation

The 4.0 scale is used by most US colleges; each letter maps to grade points weighted by course credits.

How It Works

Map letters to points.
Multiply by credits.
Divide by total credits.

Practical Applications

Semester and cumulative GPA.
Applications abroad.

How GPA is calculated

Grade point average is a credit-weighted average of your grade points. Multiply each course's grade points by its credit hours, add those products, and divide by the total credits: GPA = Σ(grade points × credits) ÷ Σ credits. On the common 4.0 scale an A is 4, B is 3, C is 2, D is 1 and F is 0, with plus and minus grades in between at many universities.

Weighting by credits matters: a 4-credit course affects your GPA twice as much as a 2-credit one.

Worked example

Courses: Math A (4 credits), Physics B+ (3.3 points, 4 credits), English A− (3.7 points, 3 credits) and a lab B (3 points, 1 credit). Weighted points are 16 + 13.2 + 11.1 + 3 = 43.3 over 12 credits, so GPA = 3.61.

Different grading scales

Indian universities usually use a 10-point CGPA scale, and converting to a 4.0 GPA is not a simple ratio; foreign admissions offices often ask for an official conversion from WES or a similar body. Check how your target institution treats repeated courses and pass/fail credits, because policies differ.

Example 1: A, B+, A−, C

12 credits.

Inputs

Letter grades (comma separated): A, B+, A-, C · Credits (same order): 3, 4, 3, 2

= entered

Step 1

Points: A(4)×3 + B+(3.3)×4 + A-(3.7)×3 + C(2)×2

Step 2

GPA = Σ(points × credits) / Σ credits = 3.36

GPA (4.0 scale)

Result

= 3.36

Example 2: all B

GPA 3.0.

Inputs

Letter grades (comma separated): B B B · Credits (same order): 3 3 3

= entered

Step 1

Points: B(3)×3 + B(3)×3 + B(3)×3

Step 2

GPA = Σ(points × credits) / Σ credits = 3

GPA (4.0 scale)

Result

= 3
