Enter your assignment or course components — like Homework, Midterm, and Final Exam — along with their scores and weights. The Grade Calculator computes your weighted overall grade as a percentage and letter grade, so you always know exactly where you stand in class.

A weighted grade accounts for the relative importance of each assignment or exam in your final grade. It is calculated by multiplying each component's score by its weight (as a decimal), then summing those products. For example, scoring 80% on an assignment worth 30% contributes 24 points toward your final grade.
An unweighted grade is simply the average of all your scores, treating every assignment equally. A weighted grade assigns different levels of importance to each component — so a final exam worth 50% impacts your grade much more than a quiz worth 5%. Most college courses use weighted grading.
Ideally yes — if your weights total 100%, the calculator gives you a straightforward weighted average. If they don't sum to exactly 100%, the calculator still computes a proportional weighted average by dividing the total weighted score by the sum of your entered weights.
Most grading scales use: A (90–100%), B (80–89%), C (70–79%), D (60–69%), and F (below 60%). Some schools use +/- modifiers (e.g. A-, B+). This calculator uses a standard percentage-to-letter-grade conversion, but always check your course syllabus for your specific scale.
Yes. When using percentage mode, enter each score as a percentage out of 100 and its corresponding weight. For point-based grading, enter each score as points earned out of the maximum points, and use the point totals as weights — the calculator will normalize them automatically.
If you know your current grade and the weight of your final exam, you can rearrange the weighted grade formula: Final Needed = (Target Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight. Enter your current components here to find your running grade, then use that value in the final exam calculator.
Simply leave those component rows blank or set their weight to 0. The calculator will only include components where both a score and a weight greater than 0 have been entered, giving you a partial weighted average based on completed work.
You can include extra credit by entering a score above 100% for that component (e.g. 105%). As long as your course allows scores above 100, the weighted calculation will reflect the bonus in your overall grade naturally.
