Uses the standard 4.0 scale. A+ = A = 4.0. Verify your institution's specific grade point scale as some schools have minor variations.

How GPA Calculation Works

GPA uses a weighted average where each course's contribution is proportional to its credit hours. A 4-credit course has twice the impact on your GPA as a 2-credit course. This is why high-credit courses (labs, core requirements) matter more to your overall average.

The standard 4.0 scale: A/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. Many U.S. colleges use exactly this scale, though some have minor variations.

To verify: a student taking three 3-credit courses (A, B+, B) has quality points: (4.0×3) + (3.3×3) + (3.0×3) = 12 + 9.9 + 9 = 30.9 ÷ 9 credits = GPA of 3.43.

GPA Calculator FAQs

How is GPA calculated?
GPA = Total Quality Points ÷ Total Credit Hours. Quality points for each course = Grade Points × Credit Hours. For example, an A (4.0) in a 3-credit course = 12 quality points. Sum all quality points, divide by total credit hours.
What is a good GPA?
A 4.0 GPA is a perfect A average. Generally: 3.7+ is exceptional (A range), 3.0–3.6 is good (B range), 2.0–2.9 is average (C range). Many graduate schools require a minimum 3.0 GPA. Scholarships, honors programs, and competitive employers often set specific GPA requirements.
What is the difference between GPA and cumulative GPA?
A semester GPA is calculated for one term only. Cumulative GPA covers all semesters combined. This calculator computes a GPA for the courses you enter — to calculate your cumulative GPA, either enter all courses you've ever taken, or add your current cumulative GPA weighted by credits completed.
Does an A+ affect GPA differently than an A?
On the standard 4.0 scale, A+ and A are both worth 4.0 grade points. This is the most common grading scale used in the U.S. Some schools use a 4.3 scale where A+ = 4.3, but this is less common. Check your school's official grading policy.
How do I raise my GPA?
Your GPA is a weighted average, so recent grades in high-credit courses have the most impact. To raise a 3.0 GPA to 3.5 over two more semesters, you would need to average approximately 4.0 in those semesters (the exact amount depends on credits completed). Retaking failed or low-grade courses (where the new grade replaces the old) is another effective strategy if your school allows it.
What is the difference between a weighted and unweighted GPA?
An unweighted GPA treats all courses equally (on a 4.0 scale). A weighted GPA gives extra points for harder courses — for example, AP or honors courses might be worth 5.0 instead of 4.0 for an A. This calculator uses the standard unweighted 4.0 scale. Check if your school or program uses a weighted scale.
