Enter your assignment or category name, score received, and weight percentage for each graded item in your syllabus. The Grade Weight Calculator computes your weighted course grade and shows how each category contributes to your final result — perfect for checking your standing before finals.

A grade weight calculator computes your overall course grade by multiplying each assignment or category score by its assigned weight (percentage of the total grade) and summing the results. This reflects how your syllabus values different components — for example, a final exam worth 35% impacts your grade more than homework worth 10%.
Yes — for a complete grade calculation, your weights should total 100%. The calculator shows you the 'Total Weight Entered' so you can track this. If your weights don't reach 100%, the result reflects only the entered portion. You can still use it mid-semester to track your current standing on completed work.
Multiply each category's score by its weight (as a decimal), then add all those products together. For example: 85% × 0.20 + 90% × 0.35 = 17 + 31.5 = 48.5 points from those two categories. Sum all categories to get your final weighted grade. This calculator does that math automatically.
Use weighted categories if your syllabus lists percentages for each component — like 'Homework: 20%, Exams: 50%'. Use total points if your teacher simply adds up all earned points against all possible points. Most college syllabi use weighted categories, so this calculator is ideal for those courses.
To find the required final exam score, rearrange the weighted grade formula: Required Final Score = (Target Grade − Sum of other weighted scores) ÷ Final Exam Weight. For example, if you need an 80% overall, your other categories give 55 weighted points, and the final is worth 30%, you need (80 − 55) ÷ 0.30 = 83.3% on the final.
Enter extra credit as a score above 100% in the relevant category (e.g. 105%). Some instructors add bonus points directly to your final grade — in that case, add an extra row with the bonus points as the score and a very small weight reflecting the points added to the total.
Differences can arise from rounding methods, how dropped lowest scores are handled, curves applied to individual assignments, or attendance policies. Always confirm the exact weighting scheme from your official course syllabus and check with your instructor if results differ significantly.
Absolutely. Just enter the categories and scores you have so far. The 'Weight Remaining' output tells you how much of your grade is still undetermined. You can experiment with different projected scores in remaining categories to plan what you need to achieve your target grade.
