How to Use This Calculator
- Gather all your graded assignments, tests, and projects along with their point values and weights.
- For each assignment, enter the name (optional), your score, the maximum possible score, and the weight percentage.
- Click "Add Assignment" to include additional items. The calculator updates your overall grade automatically.
- Review the total weight to ensure it equals 100%. Adjust weights if needed to match your course grading policy.
Weighted Grade Formula
A weighted grade accounts for the relative importance of each assignment category. The formula multiplies each assignment's percentage by its weight, then sums these weighted percentages:
Example: If you scored 90% on a test worth 40% and 85% on homework worth 60%, your weighted grade is (90×0.40 + 85×0.60) = 36 + 51 = 87%.
Full Description
The ReadyCalculator Grade Calculator helps students track their academic performance throughout a semester by computing weighted averages from multiple assignments. Unlike simple averages, weighted grades reflect the importance instructors place on different types of work—ensuring that a final exam worth 40% has more impact than a homework assignment worth 5%.
Use this tool to monitor your progress, identify areas needing improvement, and plan study time effectively. By entering assignments as you receive grades, you can see how each new score affects your overall average. This real-time feedback helps you make informed decisions about where to focus your efforts.
The calculator supports any number of assignments and automatically handles decimal weights. Whether you're calculating a single test grade or tracking an entire semester's worth of work, this tool provides accurate, instant results to keep you on top of your academic goals.
Frequently Asked Questions
How do I determine the weight of each assignment?
Check your course syllabus or grading policy. Most instructors list the percentage weight for each category (e.g., homework 20%, exams 50%, projects 30%). If weights aren't specified, you may need to estimate based on point values or ask your instructor.
What if my assignment weights don't add up to 100%?
The calculator will still compute your grade, but the result may not reflect your true course average. Ensure all assignment categories are included and their weights sum to exactly 100% for accurate results.
Can I use this for a single test or assignment?
Yes! Enter just one assignment with a weight of 100% to calculate the percentage grade for that single item. This is useful for understanding how one test score affects your overall average.
How do I calculate my grade if I don't know the maximum score?
If you only have a percentage grade, enter that percentage as both the score and max score (e.g., 85/85). Alternatively, use the percentage directly in a category-based calculator if your course uses weighted categories.
