Calculate your weighted final grade, or find the exact score you need on your final exam to hit the grade you want.
A final grade calculator works out the overall percentage you've earned in a class once every graded category, homework, quizzes, tests, projects, and participation, is weighted correctly. Instead of averaging scores as if they all count the same, it multiplies each category by its actual weight, so a test worth 40% of your grade influences the result far more than a quiz worth 5%.
This tool has two modes. The Weighted Grade tab adds up your categories to give you the grade you currently have. The Required Exam Score tab flips the question around: given your current grade and the exam's weight, it tells you exactly what you need to score on the final to land on a target grade like an A or a B.
The formula behind a weighted final grade is: Final Grade = ฮฃ(Weight ร Score) รท ฮฃ(Weight). In plain terms, multiply each category's score by its weight, add those results together, then divide by the total weight. This is exactly what the Weighted Grade tab does the moment you enter your categories, so you don't have to run the math by hand for a semester grade, a college course, or a high school report card.
If you already know your current grade and how much the final exam counts, the required score is: Required Score = (Desired Grade โ Current Grade ร (1 โ Exam Weight)) รท Exam Weight. Enter your numbers in the Required Exam Score tab and the calculator solves this instantly, including flagging it clearly if the target is mathematically out of reach or already secured.
Multiply each category's score by its weight, add the weighted scores together, then divide by the total weight. This calculator does that automatically when you enter your categories and their weights.
List every graded category for the semester with its weight and your score in each, then use the Weighted Grade tab to get your semester average instantly.
Switch to the Required Exam Score tab, enter your current grade, the exam's weight toward your final grade, and your target grade. The calculator solves for the exact score you need.
A weighted grade multiplies each category's percentage score by its assigned weight, sums the results, and divides by the total weight so the final number reflects how much each part actually counts.
Yes. Both modes work with any weighting system, so they apply equally to high school courses, college classes, and semester or term-based grading.
