Grade Calculator

Two tools for one course: compute your weighted grade from scored items and their syllabus weights, and find the exact score you need on the final exam to reach a target grade. For whole-semester averages across courses, use the GPA Calculator.

Weighted course grade

Example: 90% ×30 + 80% ×20 + 70% ×50 → 78%.

Item 1

Item 2

Item 3

Item 4

Item 5

Item 6

Item 7

Item 8

Fill in at least one item to see the grade.

What do I need on the final?

Example: 78% now, final worth 40%, target 80% → need 83%.

Enter all three values to see the needed score.

Weighted grades, plainly

A syllabus like "homework 30%, midterm 20%, final 50%" means each category's average is scaled by its share before summing. In the example above the weighted grade is 78% — noticeably lower than the plain average of 90, 80, and 70, because the weakest score carries half the weight. Entering only the graded-so-far items (weights summing under 100%) gives your current standing.

Planning for the final

The needed-score formula makes trade-offs concrete: every extra point you carry into the final reduces the required final score by (1 − w)/w points — with a 40% final, each point of current grade is worth 1.5 points of final-exam pressure. Run the numbers before exam week, while there is still time to change the inputs.

Frequently asked questions

How does grade weighting work?

Each item’s score is multiplied by its weight (its share of the course grade), and the sum is divided by the total weight entered. If your entered weights total less than 100%, the result is your average on the graded portion so far.

How is the "needed on the final" figure derived?

From needed = (target − current × (1 − w)) ÷ w, where w is the final’s weight as a fraction. With a 78% average, a final worth 40%, and an 80% target, you need (80 − 78×0.6) ÷ 0.4 = 83%.

What if the needed score is above 100%?

Then the target is mathematically out of reach on the final alone, and the calculator says so — useful to know early, while extra credit or grade replacement policies can still help.

Can I mix points-based and percent-based items?

Convert points to percentages first (score ÷ maximum × 100), then enter the percentages with their syllabus weights.
