How weighted grades work
Each assignment contributes proportionally to the final grade based on its weight. A midterm worth 40% counts twice as much as a quiz worth 20%.

How to use Grade Calculator
Enter each assignment or category name, your score (out of 100), and its weight as a percentage. Click Calculate Grade to see your weighted final grade and letter grade equivalent.
Weights must add up to 100% for the result to be accurate. For example: Midterm 40% + Final 60% = 100%.

Letter grade cutoffs
A = 90+, B = 80–89, C = 70–79, D = 60–69, F = below 60. These are common cutoffs — your institution may differ.
Answers
Grade Calculator FAQs
How do I calculate a weighted grade?
Multiply each score by its weight, add all results, then divide by total weight. This calculator does it automatically.
What if my weights do not add up to 100%?
The calculator still works but divides by actual total weight, so the result is still a valid weighted average.
What grade do I need on the final to get an A?
Enter your current scores with their weights, then adjust the final exam score until the result shows 90%.
What is a weighted GPA?
A weighted GPA gives extra points for harder courses (AP or IB). This calculator is for assignment-level grade calculation.
