Grade Calculator — Weighted Average & Final Exam Needed
Two modes: (1) compute a weighted course grade from up to 6 categories, or (2) find the score you need on the final exam to hit your target grade.

Frequently asked questions
How are weighted grades calculated?
Each category's grade is multiplied by its weight (as a fraction), then summed. For example: Homework 90% × 0.20 + Quizzes 85% × 0.15 + Midterm 82% × 0.20 + Final 0% × 0.25 + Participation 95% × 0.10 + Project 88% × 0.10. If weights sum to 100%, the result is your weighted average directly. If not, divide the sum by the total weight to normalize.
What if my weights don't add to 100%?
The calculator normalizes — it divides the weighted sum by the total of your weights so the result is still a 0–100 percentage. But weights that don't sum to 100% usually mean a category is missing or duplicated. Check your syllabus carefully if the calculator flags this.
How much can a final exam change my grade?
It depends on the final's weight. If the final is worth 25% and you have a 90% going in, a perfect 100% on the final lifts you to 92.5%; a 0% drops you to 67.5%. The lower-weight the final, the harder it is to change a strong grade. The higher-weight, the more it can swing either direction.
What is a 4.0 GPA equivalent?
On most US college scales: 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 = 0.0. Some schools use a +/- system with slightly different values. Your GPA is the average of all course GPA values, weighted by credit hours. See our GPA calculator for the full calculation.
How can I raise my grade?
Three highest-leverage tactics: (1) Identify the highest-weight remaining category and focus there. A great final does more than a great homework score if the final is weighted higher. (2) Attend office hours — professors weight participation higher when they know you. (3) Re-attempt past mistakes — for many courses, the same problem types appear on every exam.
