What Is GPA?

Your Grade Point Average (GPA) is a single number that summarizes your academic performance by converting letter grades into points and averaging them, weighted by how many credit hours each course is worth. Most US high schools and colleges use a 4.0 scale, where an A is worth 4.0 points and an F is worth 0.0 points. GPA lets schools, scholarship committees, and employers compare performance across students quickly, even though the underlying coursework may differ.

Weighted vs. Unweighted GPA

An unweighted GPA treats every class the same regardless of difficulty, capping out at 4.0. A weighted GPA gives extra points for honors, AP, or IB courses (often adding 0.5 to 1.0 points), so a weighted GPA can exceed 4.0. This calculator uses the standard unweighted 4.0 scale below; if your school weights certain courses, add the extra points to that course's grade value manually before calculating.

The Standard 4.0 GPA 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

To calculate GPA manually, multiply each course's grade points by its credit hours, add up all those totals, then divide by the total number of credit hours attempted.

Cumulative vs. Semester GPA

Your semester GPA only reflects the courses taken in that term. Your cumulative GPA averages every graded course across every term you have completed. To calculate a new cumulative GPA, treat your existing cumulative GPA as one line item: multiply it by your total prior credit hours, add that to the new semester's grade-point total, then divide by your combined total credit hours.

Common GPA Questions

• Repeated courses: Many schools replace the old grade with the new one in GPA calculations (grade replacement), while others average both attempts. Check your school's policy.
• Pass/Fail classes: These usually do not count toward GPA at all and should be left out of this calculator entirely.
• Transfer credits: Some schools only count credit hours from transfer courses, not the grade, so those courses may not affect GPA.
