🎓 Grade Calculator

Multiply each grade by its weight (as a decimal), then add all those values together. For example: if you scored 90% on a 40%-weighted midterm and 80% on a 60%-weighted final, your weighted average is (90 × 0.4) + (80 × 0.6) = 36 + 48 = 84%.

Use the Final Exam Needed tab. Enter your current grade, the grade you want in the course, and the weight of the final exam. The formula is: Required Final Score = (Desired Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight. This calculator handles it all automatically.

The 4.0 scale is the most common GPA system in the US. An A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus and minus grades are factored in: A− = 3.7, B+ = 3.3, etc. Your GPA is the weighted average of all grade points across all credit hours.

At most US colleges, a 3.5+ GPA is considered excellent and may qualify for Latin honors (magna cum laude). A 3.0–3.4 is good; 2.5–3.0 is average; below 2.0 usually puts a student on academic probation. Graduate school typically requires 3.0+ for admission.

A simple average treats every score equally. A weighted average gives more importance to certain assignments. For example, if your final exam is worth 40% and a quiz is worth 5%, a bad quiz hurts you much less than a bad final. Most college courses use weighted grading.

In a standard US grading scale: 90–100% = A, 80–89% = B, 70–79% = C, 60–69% = D, below 60% = F. So a 75% is a C. Some institutions use different thresholds, so always check your course syllabus for the exact grade boundaries.
