Semester & cumulative GPA

Leave Type as Regular for college. High schools often add +0.5 for Honors and +1.0 for AP or IB.

Uses the common 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3 …). Some schools count A+ as 4.3 or use different values, so check your school’s handbook.

How GPA is calculated

Turn each letter grade into grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0).
Multiply the points by the class’s credit hours. A B+ (3.3) in a 4-credit class = 13.2 quality points.
Add up all quality points and divide by total credits.

Example: A (4.0 × 3) + B+ (3.3 × 4) + A− (3.7 × 4) + B (3.0 × 3) = 12 + 13.2 + 14.8 + 9 = 49 points ÷ 14 credits = 3.50 GPA.

Letter grade to GPA conversion (4.0 scale)

The most common US scale. Percent cut-offs vary by school.
Letter	Percent	Grade points	Weighted Honors / AP
A+ / A	93–100%	4.0	4.5 / 5.0
A−	90–92%	3.7	4.2 / 4.7
B+	87–89%	3.3	3.8 / 4.3
B	83–86%	3.0	3.5 / 4.0
B−	80–82%	2.7	3.2 / 3.7
C+	77–79%	2.3	2.8 / 3.3
C	73–76%	2.0	2.5 / 3.0
C−	70–72%	1.7	2.2 / 2.7
D+	67–69%	1.3	1.8 / 2.3
D	65–66%	1.0	1.5 / 2.0
F	Below 65%	0.0	0.0

Weighted vs. unweighted GPA

An unweighted GPA uses the 4.0 scale for every class. A weighted GPA gives extra points for harder classes, usually +0.5 for Honors and +1.0 for AP, IB or dual-enrollment, so it can go above 4.0. Colleges see both. Many recalculate GPA their own way, so your class choices matter as much as the number.

How to raise your GPA

Classes with more credits move your GPA more. Focus there first.
Early in college each class has a big effect. After 90+ credits even a 4.0 semester only nudges your cumulative GPA.
Ask about grade replacement: some schools let a retake replace the old grade.

Step-by-step examples are in how to calculate GPA.

GPA Calculator FAQs

What is a good GPA?

In the US, a 3.0 (B average) is generally considered good, a 3.5+ is strong, and 3.7+ is excellent. Competitive colleges and scholarships often look for 3.5 or higher.

How do I calculate my cumulative GPA?

Multiply your current GPA by the credits you have completed, add this term’s quality points, and divide by the total credits. Enter your current GPA and credits above and the calculator does it for you.

Is an A+ worth 4.3?

At some colleges, yes. Most high schools and many colleges cap A+ at 4.0. This calculator uses 4.0.

What do I need on my final to pass?

Use the final grade calculator: enter your current grade, the exam weight and 60 or 70% (whatever passing is in your class).

Do pass/fail classes count in GPA?

Usually not. Pass/fail credits count toward graduation but are left out of the GPA, so don’t enter them.
