What is a weighted grade?

A weighted grade is a course grade where each category counts for a different share of the final result. Homework might be 20%, quizzes 15%, exams 45%, and the final 20%. This calculator lets you enter those category weights and your current scores, then checks whether the included weights add to 100%. You can also test a target grade to see what score you need on a final exam or remaining assignment.

Weighted grade formula

The basic formula is:

Weighted grade = (score1 x weight1 + score2 x weight2 + ... ) / total included weight

If your included weights add to 100%, the result is a full course-grade estimate. If you only enter completed categories, the result is a current-grade estimate for the categories you have so far.

This method follows the common syllabus approach: each category score is multiplied by its category weight, then the weighted points are added together. The calculator keeps blank grades out of the current-grade result unless you enter a score and include that row.

Examples

  • Homework 20% at 92, quizzes 15% at 86, exams 45% at 84, with the final still remaining.
  • Labs 30%, participation 10%, tests 40%, and final 20% for a science course.
  • A final-heavy class where the final exam is 40% of the total grade.
  • A course where only 75% of the grade has been completed so far.
  • A target-grade plan where you want a 90% overall and need to know the final exam score required.

When to use this calculator

  • Before a final exam, to see what score you need.
  • After grades are posted, to check your current weighted average.
  • When your syllabus lists category weights but your gradebook shows separate scores.
  • To compare which category has the biggest effect on your final grade.
  • To explain weighted grading to a student, parent, or tutor.

Important notes

Different schools can use different grading scales, rounding policies, extra credit rules, and dropped-score policies. This calculator is meant for planning and checking the math, not for replacing your official gradebook or syllabus rules.

Calculation method and trust

WeightedGrade runs the calculation in your browser and does not send raw scores, category names, or target grades to analytics. The formula, examples, and FAQ were reviewed for the common percentage-based weighted grading model on May 2, 2026.

The calculator does not automatically apply dropped lowest scores, curve adjustments, extra credit policies, late penalties, or school-specific rounding rules. If your class uses one of those policies, adjust the category score first or compare the result with your official gradebook.

Frequently asked questions

How do I calculate a weighted grade?

Multiply each category score by that category's weight, add the weighted points together, then divide by the total included weight. If all course categories are entered, the weights should usually add to 100%.

What if my weights do not add to 100%?

If the weights are below 100%, the result is a current-grade estimate for the categories you entered. If the weights are above 100%, check the syllabus and fix duplicated or incorrect category weights.

Are blank grades counted as zero?

Blank scores are treated as missing, not zero. If a missing assignment should count as zero, enter 0 as the score and keep that row included.

How do I calculate what I need on my final?

Enter your current categories, then enter a target grade and the weight of the final or remaining work. The calculator estimates the score needed on that remaining weight.

Can I use points instead of percentages?

This version works with percentages. If your gradebook shows points, convert each category to a percent first by dividing earned points by possible points and multiplying by 100.

Is this the same as GPA?

No. A weighted grade calculator estimates one course grade from category weights. GPA calculators combine grades across multiple courses and credit hours.

Does this save my grades?

No. The calculator runs in your browser. It does not send raw scores, category names, or target grades to analytics.
