GPA Calculator

GPA (Grade Point Average) is the average of your letter grades converted to a 4.0 scale, weighted by credit hours. The formula is: GPA = sum of (grade points x credits) divided by total credits. An A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0. A 3-credit course weighs three times more than a 1-credit course in your final GPA.

Unweighted GPA uses a flat 4.0 scale - an A is 4.0 in any course. Weighted GPA adds bonus points for harder courses: Honors classes get +0.5 (max 4.5), and AP, IB, or Dual Enrollment classes get +1.0 (max 5.0). Most US high schools report both. Colleges typically recalculate to unweighted using their own formula.

For high school, a 3.5 unweighted GPA is considered competitive for most colleges. A 3.7+ unweighted GPA is strong for selective schools, and 3.9+ for highly selective. For college, a 3.0 GPA is generally the minimum for good academic standing, 3.5+ qualifies for Dean's List at most schools, and 3.7+ for cum laude or higher honors at graduation.

Use this 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. Some schools count A+ as 4.3, but most cap at 4.0 for unweighted GPA. Our calculator uses the most common 4.0 cap convention.

Multiply each course's grade points by its credit hours to get quality points, then sum all quality points across all semesters and divide by total credit hours. Our calculator does this automatically as you add courses. You can also use the Target GPA Planner to see what semester GPA you need to reach a cumulative goal.

Yes. An F counts as 0.0 grade points but still uses the course's credit hours, which pulls your GPA down significantly. If you retake the course, most schools use the higher grade in the GPA calculation (grade replacement policy) but still display the original F on your transcript. Check your institution's policy because it varies.

A credit hour is a measure of academic workload. In US colleges, one credit hour typically equals one hour of classroom time per week for a semester (15 weeks total). A standard 3-credit course meets three hours per week. Lab courses often add 1 credit per lab session. High school courses are usually 1 credit each (for a full-year course).

The math is exact - we use the standard 4.0 scale formula adopted by most US high schools and universities. Some schools use slightly different scales (A+ = 4.3, plus/minus variations, or a 5.0 weighted maximum for AP only). If your school uses a different scale, check your transcript for the official conversion. Our weighted mode uses the common +0.5 honors and +1.0 AP convention.

Yes. Most high schools send the weighted GPA on the transcript, and colleges see it. However, many selective colleges recalculate GPA using only academic courses (excluding gym, art electives) and apply their own weighting formula. Standardized recalculation lets colleges compare students from different high schools fairly. Focus on grade trends and course rigor, not just the GPA number.

A 4.0 GPA roughly corresponds to a 93-100% average using the standard US scale: 90-100 = A (4.0), 80-89 = B (3.0), 70-79 = C (2.0), 60-69 = D (1.0), below 60 = F. International scales differ: a UK First (70%+) is roughly equivalent to a US 3.7+ GPA, and a Turkish 4.00/4.00 system maps directly. Use a separate converter for international GPA conversion.

Take more credit hours of A-level work because credit hours weight the average. Retake failed or D courses if your school offers grade replacement. Take courses you'll excel in alongside difficult ones to balance the average. Use the Target GPA Planner above to see exactly what semester GPA you need to hit a specific cumulative target. Note: it's mathematically harder to raise GPA after many credits because each new course has less weight on the cumulative average.
