Goal: what do I need to finish?
Need 92.56%

You need 92.56% on the remaining 35% of your grade to finish at A- (90%+).

A weighted grade counts some work more than others. Enter each category's score and the weight your syllabus assigns it; this calculator multiplies each earned fraction by its weight, adds them, and divides by the total weight. A 95 on homework worth 20% and a 70 on an exam worth 80% yield a 75, not an 82.5.

The formula

weighted % = Σ(score ÷ max × weight) ÷ Σ(weight) × 100

Heavier categories move the average more. The exam at 80% weight dominates the homework at 20%, which is why a simple average overstates a grade with one big-weight component.

How to use it

  1. 1

    List your grade categories

    Add a row per category — homework, quizzes, midterm, final — with the score you earned out of its maximum.

  2. 2

    Assign the syllabus weights

    Enter each category's weight as the percentage of the course it counts for. The weights can total 100 or any consistent set of numbers.

  3. 3

    See the true weighted grade

    The result is the weight-adjusted percentage, which differs from a plain average whenever the categories carry unequal weight.

Frequently asked questions

Why is my weighted grade lower than the simple average?
Because a high score sits in a low-weight category. The average treats every score equally; weighting lets a heavy exam pull the overall grade toward its value.
Can I mix percentages and point weights?
Keep one system per calculation. Use all percentages (20/30/50) or all point values, since the tool normalizes by whatever total you enter.
How do I handle a category with several grades?
Average that category's scores first, enter the result as one row, then give the row the category's full weight.
