Grade Calculator
Calculate your weighted average, find what grade you need on your final exam, or check if you can still pass the course.
How grade calculations work
Weighted grade average = Σ(Grade × Weight) ÷ Σ(Weights). If weights don't add to 100%, the calculator normalises them. The "required final grade" formula works backwards from your target to find what you need on the exam.
Required Final = (Target − Current × (1 − FinalWeight)) ÷ FinalWeight
GPA Conversion = A(90-100)=4.0 · B(80-89)=3.0 · C(70-79)=2.0 · D(60-69)=1.0
Unweighted: simple average of all grades. Weighted: accounts for each assessment's importance. Finals typically worth 30-40%, quizzes 10-15%. Always use weighted average for accurate course grade.
Use the "Final Exam Needed" mode before finals to know exactly what score you need. If you need 95%+ on the final, consider whether extra credit or improved earlier assignments are possible.
US 4.0 scale: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D=1.0, F=0. Most graduate schools require 3.0+ GPA for admission.
Most institutions: D (60%) is passing. Many majors require C (70%) or better. Professional programs (medicine, law, engineering) often require 75-80% minimum to proceed.
