How GPA Is Calculated

GPA is the average of your grade points, weighted by credit hours:

GPA = Σ(grade points × credits) ÷ Σ(credits)

Each letter grade maps to a point value on the 4.0 scale. For example, an A is 4.0, a B is 3.0, and so on. If a 3-credit A (3 × 4 = 12) is combined with a 2-credit B (2 × 3 = 6), the GPA is (12 + 6) ÷ (3 + 2) = 18 ÷ 5 = 3.6.

Standard 4.0 Scale

Letter Grade	Grade Points
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	1.0
F	0.0

Note: Some schools use weighted GPAs (honors/AP courses count more) or a different scale. This calculator uses the common unweighted 4.0 scale. Check your school's specific policy.

What GPA Do You Need?

Goal	Typical Target
Graduate high school (most states)	2.0 (C average)
Most four-year colleges	2.5–3.0
Competitive universities	3.5+
Some scholarships / honors	3.5–3.8+

Tips to Raise Your GPA

Focus on high-credit courses: A good grade in a 4-credit class moves your GPA more than in a 1-credit class.
Retake failed courses: Many schools replace the F with the new grade in your GPA.
Prioritize struggling subjects: Early help — tutoring, office hours — beats catching up later.
Keep a steady effort: Consistent daily work beats last-minute cramming.

Frequently Asked Questions

What's a "good" GPA?

It depends on your goals. A 3.0 is a solid B average and qualifies for many programs. Competitive colleges and scholarships often look for 3.5+. For jobs, experience and skills often matter as much as the exact number.

What is a weighted GPA?

Weighted GPAs give extra points for advanced courses (like AP, IB, or honors), so they can exceed 4.0. Colleges often recalculate on their own scale, so check their requirements.

How do I calculate my cumulative GPA?

Add all your grades across every course, weighted by credits, and divide by total credits — exactly what this calculator does. Just enter every course you've taken.
