Know your grade before the report card.
Enter each assignment or category, its score and how much it is worth, and see your weighted overall grade, your letter grade, and exactly how much every item pulls your average up or down.

Weighted grades, explained
How Weighted Grades Are Calculated
A weighted grade multiplies each score by its weight percentage, sums the products, and divides by the total weight. For example, if an exam worth 40% of your grade has a score of 90, it contributes 36 points (90 x 0.40) to your weighted average.
Letter Grade Conversion
The standard letter grade scale is: A (93-100), A- (90-92), B+ (87-89), B (83-86), B- (80-82), C+ (77-79), C (73-76), C- (70-72), D+ (67-69), D (63-66), D- (60-62), and F (below 60). Some institutions use different cutoffs.
Why Weights Matter
Weights reflect the relative importance of each assignment. A final exam weighted at 40% affects your grade twice as much as a midterm at 20%. Understanding weights helps you prioritize study time for maximum grade impact.
Improving Your Grade
To improve your grade, focus on assignments with higher weights that are still upcoming. Calculate what score you need on remaining assignments to reach your target grade. This strategic approach maximizes your effort-to-grade-improvement ratio.
Common questions
What if my weights do not add up to 100%?
The calculator normalizes the weights by dividing by the total weight entered. If your weights add up to 75% because some assignments are not yet graded, the calculator computes your current weighted average based on the completed work.
How do I calculate what I need on the final?
Enter your current scores and weights, then adjust the final exam score until the weighted average reaches your target grade. This shows the minimum final exam score needed.
What is the difference between weighted and unweighted grades?
Unweighted grades treat all assignments equally regardless of their importance. Weighted grades account for each assignment contribution to the total grade, giving more influence to heavily-weighted items like exams.
Can extra credit push me above 100%?
Yes. If you score above 100 on any assignment due to extra credit, the calculator will compute a weighted average above 100 if appropriate. The letter grade will still be A or A+ for scores at or above 93.
Estimates for planning only. Your school may use different letter-grade cutoffs, rounding rules, drop-lowest policies or extra-credit handling. Confirm your exact grading scheme with your instructor or syllabus.
