Weighted GPA Calculator

To calculate weighted GPA: 1) Assign each course a weight (Regular = 1.0, Honors = 1.25, AP/IB = 1.5), 2) Multiply each grade point by credits and weight, 3) Sum all values, 4) Divide by total credits. Formula: Weighted GPA = Σ(Grade Points × Credits × Weight) ÷ Σ Credits.

Unweighted GPA uses a standard 4.0 scale where all courses count equally (A = 4.0). Weighted GPA adds extra points for advanced courses—typically +0.5 for Honors and +1.0 for AP/IB. This means an A in AP might be 5.0, resulting in a weighted GPA above 4.0.

A good weighted GPA on a 5.0 scale: 4.5+ = Outstanding (Ivy League competitive), 4.0-4.5 = Excellent (top universities), 3.5-4.0 = Very Good (good colleges), 3.0-3.5 = Good (most colleges).

AP classes typically add +1.0 to the standard grade point. So an A (4.0) in an AP class becomes 5.0, a B (3.0) becomes 4.0, and so on. Some schools use +0.5 for AP and +1.0 for IB. Check with your school for the exact scale.

Yes, weighted GPA can exceed 4.0. On a 5.0 scale, the maximum weighted GPA is 5.0 (straight A's in all AP classes). On a 6.0 scale (some schools), the maximum is 6.0. Unweighted GPA cannot exceed 4.0.

To convert unweighted to weighted GPA, you need to know which courses were advanced. For each Honors course, add 0.5 to the grade point; for each AP/IB course, add 1.0. Then recalculate using the weighted formula. Without course-level data, you can't accurately convert.

Colleges often recalculate GPA using their own formula. Some use unweighted GPA for comparison; others use a capped weighted GPA (e.g., UC system caps at 4.4). Many colleges strip out non-academic courses and recalculate. Check each college's admission policy.

The University of California (UC) system calculates a capped weighted GPA on a 4.0 scale. It awards +1.0 for each AP, IB, or UC-approved Honors course (up to 8 semesters). The maximum UC weighted GPA is 4.40, calculated from grades in 10th and 11th grade only.

IB (International Baccalaureate) courses typically carry the same weight as AP courses—an additional +1.0 on the grade point scale. Higher Level (HL) IB courses may receive the full +1.0, while Standard Level (SL) may receive +0.5. Policies vary by school.

A weighted GPA on a 5.0 scale means the highest possible GPA is 5.0, awarded for A's in AP/IB courses. Regular A = 4.0, Honors A = 4.5, AP/IB A = 5.0. This scale rewards students for taking advanced courses.

Some high schools use a 6.0 weighted scale, where AP/IB courses can earn up to 6.0 for an A. Regular A = 4.0, Honors A = 5.0, AP/IB A = 6.0. This is less common but used in some competitive districts.

On a 100-point scale, weighted GPA adds 5-10 points for advanced courses. For example, a 90 in an AP class might become 95-100. Formula: Weighted Score = Base Score + Bonus. Then average all weighted scores. Our calculator supports 100-point scale input.
