What is a weighted grade?

A weighted grade gives different categories different importance. For example, if the final exam is 40% of your grade, it has more impact than homework at 20%.

How do I calculate my grade with weights?

Multiply each category score by its weight percentage, then add all the products together. For example: Homework (90%) × 20% + Midterm (75%) × 30% + Final (82%) × 50% = 81.5%.

What happens if my weights don't add up to 100%?

The calculator shows a warning and still displays a result, but it will be an incomplete estimate. Check with your instructor for the correct weights.

How does extra credit affect my grade?

Extra credit adds to your numerator (earned points or weighted score) without increasing the denominator. This can push your grade above 100%.

How Grade Calculation Works

Percentage Weights mode: Each category (homework, midterm, final) has a percentage weight. Your score in each category is multiplied by its weight. Weights should total 100%.

Points mode: Enter points earned and points possible for each item. Grade = (total earned) ÷ (total possible) × 100%. Extra credit items add to earned points but not to the possible total.

Extra credit: Mark a row as Extra Credit to add bonus points. In Percentage Weights mode, extra credit adds to your weighted sum without consuming weight allocation.
