What's the Difference Between Weighted and Unweighted GPA?
Unweighted GPA uses a standard 4.0 scale where an A equals 4.0 regardless of course difficulty. Weighted GPA (5.0 scale) gives extra weight to advanced courses like AP (Advanced Placement), IB (International Baccalaureate), and Honors classes. For example, an A in an AP course might be worth 5.0 instead of 4.0, rewarding students who challenge themselves with rigorous coursework. In 2026, most competitive colleges consider weighted GPAs to evaluate course rigor alongside raw grades. Our calculator supports both systems, letting you calculate your GPA the way your target schools prefer.
How GPA Systems Work
Most US colleges run on a 4.0 scale, but the details vary. Many high schools use weighted scales (typically 5.0) to give extra credit for AP and IB courses. International schools often use percentages or entirely different point systems. Knowing your GPA matters for college applications, scholarship eligibility, academic probation limits, and grad school admissions — each institution sets its own thresholds.
Cumulative GPA covers every semester you've completed; semester GPA covers a single term. Some schools also calculate a separate major GPA. This calculator handles all three: enter each course, its credit hours, and the grade received, and it computes the weighted average correctly. If you're targeting Dean's List (typically 3.5+) or need to stay above academic probation (often 2.0), accurate tracking lets you know exactly where you stand.
