Weighted Grade Calculator — Calculate Grades With Weights

Calculate grades with weights to find your current class grade.
Most classes don't weight everything equally - homework might be 20% of your grade, midterms 30%, projects 25%, and the final 25%. A weighted grade calculator combines those scores into a single current class grade so you can see where you stand without treating every assignment as equally important.
Semrush shows that students describe this task in several ways: calculating grades by weight, grade calculator with weights, grade weight calculator, and even grades calculator weighted. They all point to the same problem: each score should count in proportion to the percentage, point value, or category weight assigned by the syllabus.
Instead of averaging scores equally, this calculator multiplies each score by its weight, adds the weighted scores together, then divides by the total weight entered. That makes it useful for assignment weights, category weights, weighted percentages, partial semester grades, and what-if planning.
Weighted grading is common when a course separates work into categories. Homework may be worth 15%, quizzes 10%, projects 25%, midterms 20%, and the final exam 30%. In that setup, a 95% homework average does not balance a low midterm score one-for-one, because each category contributes a different amount to the final course grade.
Use this calculator when your syllabus lists percentage weights, point categories, or grading groups. It can calculate your current grade based on completed weights, estimate a what-if grade after a future assignment, or help you understand which category will move your overall grade the most.
A simple average asks, "What is the average of these scores?" A weighted average asks, "How much should each score matter?" That distinction is the reason a weighted grade calculator is more accurate than a basic percentage calculator for classes with syllabus weights.
You can use the calculator in two ways. For a category-based class, enter each category average and its syllabus weight. For an assignment-based class, enter each assignment score and its assignment weight. Both approaches use the same weighted average formula.
Grade = Σ ( Score × Weight ) ÷ Σ ( Weight )
Each score is multiplied by its weight; the sum is divided by the total weight entered.
The division by total weight is important. If you enter only completed weights, such as 70% of the course so far, the calculator shows your current grade across the work completed. If you enter all 100% of the course, including estimated scores for future work, it becomes a what-if grade calculator for the full course.
This is also the direct answer to how to calculate grade with weights: convert each category or assignment into a score and a weight, multiply score by weight, add those products, then divide by the total of the weights. If your teacher uses points instead of percentages, the point values can act as weights because the same formula still applies.
Homework 95% (weight 20), Midterm 82% (weight 30), Project 88% (weight 20).
Grade = (95×20 + 82×30 + 88×20) ÷ (20+30+20) = 6120 ÷ 70 = 87.4%.
In this example, the midterm matters more than homework because its weight is 30 instead of 20. That is how weighted grades are calculated: the bigger weight has more influence, even when the score difference looks small.
If your class is still in progress, your completed work may not add up to 100%. That is normal. For example, homework, a midterm, and a project might total 70% of the grade so far. This calculator divides by 70 in that case, showing your grade for the completed portion of the class.
If you want a projected final grade, add rows for the remaining categories and enter estimated scores. For example, add a final exam row with a possible score and its final exam weight. That turns the calculator into a what-if planning tool and helps you see which remaining scores matter most.
Your syllabus is the best source for category weights and weighted percentages. Look for a grading table with labels like homework, quizzes, labs, participation, essays, exams, midterm, final project, and final exam. If the syllabus uses points instead of percentages, you can still use this calculator by treating each point total as a weight. A 50-point quiz and a 100-point exam can be entered as weights 50 and 100, because the formula divides by the total weight.
For a category-based class, enter each category average once. For example, use homework average 92 with weight 20, quiz average 86 with weight 10, and exams average 81 with weight 40. For an assignment-based class, enter each individual assignment score and its assignment weight. Avoid mixing both methods for the same work, because that double-counts the category.
A weighted grade calculator is best when you need to combine several scores or categories into one current grade. A final grade calculator is different: it starts with your current grade, target grade, and final exam weight, then solves for the score needed on the final exam.
If you do not know your current grade yet, use this page first to calculate weighted grades from your syllabus. Once you know the current grade before the final, use the final grade calculator to answer what score you need on the final exam. If you also want that grade as a letter or 4.0 GPA, run the percentage through the grade converter.
The weighted average tells you where your grade stands after accounting for importance. A low score in a small category may not hurt much, while a slightly lower exam score can matter a lot if exams carry most of the course weight. After you see the result, try changing one row at a time to find the most efficient way to improve your overall grade. At the end of the term, the GPA calculator turns those course grades and credit hours into a 4.0-scale GPA.
Multiply each score by its weight, add the weighted scores together, then divide by the total weight entered. The weighted grade calculator does this automatically as you type.
