How to Calculate GPA on a 4.0 Scale

GPA (Grade Point Average) is calculated by multiplying each course grade points by its credit hours, summing all grade points, then dividing by total credit hours. Formula: GPA = Σ(grade points × credits) / Σ credits.

Standard 4.0 scale: A+ = 4.0, 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 = 0.0.

Example: Biology (4 credits, A = 4.0) + Chemistry (3 credits, B+ = 3.3) + English (3 credits, A− = 3.7): Points = (4×4.0) + (3×3.3) + (3×3.7) = 16 + 9.9 + 11.1 = 37.0. Credits = 10. GPA = 37.0 / 10 = 3.70.

Frequently Asked Questions

What is a good GPA?+
3.5+ (A−) is typically considered excellent. 3.0–3.49 (B average) is good. 2.0 (C average) is the minimum to remain in good academic standing at most schools. Graduate schools often require 3.0+ for admission; top programs may require 3.5+.
What is the difference between weighted and unweighted GPA?+
An unweighted GPA uses the standard 4.0 scale for all courses. A weighted GPA gives extra points for honors, AP, or IB courses (typically +0.5 for honors, +1.0 for AP/IB). This calculator uses the unweighted 4.0 scale.
How do I raise my GPA?+
Higher-credit courses have more impact. Retaking a low-grade course (if allowed) replaces the old grade. Consistent A− to A work in future semesters will gradually raise your cumulative GPA. Early grades matter most since they have more time to compound.
What GPA do I need for graduate school?+
Most graduate programs require a minimum 3.0 GPA. Top MBA programs typically prefer 3.5+. Medical schools look for 3.5+. Some STEM graduate programs weigh GRE scores and research experience more heavily than GPA.

How GPA Is Calculated

Grade Point Average is a credit-weighted mean: multiply each course's grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0 on the common US scale) by its credit hours, sum the results, and divide by total credits.

Worked example

An A in a 4-credit course (16 points), B+ in a 3-credit course (9.9) and C in a 2-credit lab (4.0) gives 29.9 points over 9 credits — a GPA of 3.32.

Frequently asked questions

Weighted vs unweighted? Weighted scales award extra points for honors/AP courses (often up to 5.0); colleges frequently recalculate on their own scale.

Do pass/fail courses count? Usually excluded from GPA but counted toward credits earned.

How to raise a GPA fast? Early on, each course moves the average a lot; later, retaking failed high-credit courses has the biggest effect where replacement policies exist.
