Weighted vs unweighted GPA
Unweighted GPA caps every course at 4.0; weighted GPA adds Honors (+0.5) and AP/IB (+1.0) and can exceed 4.0. Which one colleges use, and how to read both.
The difference is whether course difficulty earns extra points. It changes what a GPA number means — and which number a college is looking at.
Unweighted GPA
Every course sits on the same 4.0 scale: A = 4.0, B = 3.0, and so on, down to F = 0.0. The hardest AP class and an easy elective are worth the same for an A. No GPA can go above 4.0. This is the number most colleges recalculate to, so they can compare applicants from different schools fairly. Use the unweighted GPA calculator.
Weighted GPA
Harder courses add a bonus to their grade points before averaging — most commonly +0.5 for Honors and +1.0 for AP or IB. An A in an AP class counts as 5.0 instead of 4.0, so a weighted GPA can exceed 4.0 and reach 5.0 with straight AP A’s. Class rank is often built on weighted GPA because it rewards taking a harder load. Use the weighted GPA calculator.
Same grades, two numbers
An AP A, an Honors B and a regular A: weighted that’s (5.0 + 3.5 + 4.0) ÷ 3 = 4.17; unweighted it’s (4.0 + 3.0 + 4.0) ÷ 3 = 3.67. Same report card, two very different GPAs.
Which should you report?
Report the GPA on your transcript, and know both. Many colleges recalculate to their own (often unweighted) scale using their own course list, so your “official” number can differ from any single calculator. See GPA vs percentage and the 4.0 vs 5.0 scale.
