Calculate your GPA on the standard 4.0 scale. Enter each course with its letter grade and credit hours — and switch on weighted mode to give Honors and AP/IB classes their usual +0.5 and +1.0 bonus.
📌 Uses the standard US 4.0 scale. Some schools count A+ as 4.3 or use different Honors/AP bonuses — check your school’s policy. Weighted GPA is capped at 5.0.

How to calculate GPA
To calculate GPA, convert each letter grade to grade points on the 4.0 scale, multiply by the course’s credit hours, sum the results, and divide by total credit hours. The formula is: GPA = Σ(grade points × credits) ÷ Σ(credits). Credit hours act as weights, so grades in bigger courses matter more.
To plan a semester, add your expected grades and see the result before finals — then use the final grade calculator to find what you need on each final, and the grade calculator to track weighted averages inside a single class. College students tracking a cumulative GPA across semesters should use the college GPA calculator.
Each letter grade converts to grade points (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0 and so on down to F = 0). Multiply each course’s points by its credit hours, add everything up, and divide by total credit hours. A 3-credit A and a 4-credit B gives (4.0×3 + 3.0×4) ÷ 7 = 3.43.
Unweighted GPA uses the plain 4.0 scale regardless of course difficulty. Weighted GPA adds bonus points for harder classes — typically +0.5 for Honors and +1.0 for AP or IB courses, making the maximum 5.0. High schools often report both; colleges usually recalculate applicants’ GPAs with their own method.
The US national average high school GPA is around 3.0. A GPA of 3.5–3.7 or higher keeps most college doors open, while highly selective universities typically expect 3.9+ unweighted along with a demanding course load. For college students, 3.0 is a common cutoff for internships and 3.5+ for honors (cum laude) distinctions.
Usually not — most schools cap A+ at 4.0, which is what this calculator uses. A minority of institutions count A+ as 4.3. If yours does, your official GPA will be slightly higher than the number shown here.
Credit hours are the weights: a grade in a 5-credit course moves your GPA five times as much as the same grade in a 1-credit course. This is why a bad grade in a high-credit core course hurts more than one in a small elective — and why retaking high-credit courses is the fastest way to raise a GPA where retakes replace the old grade.
