How to Use the Assignment Grade Calculator
This calculator lets you track your grade across multiple assignments throughout the semester, and answer the important question of what score you need on an upcoming assignment to hit your grade goal.
Calculate tab: Enter each assignment with the score you received and the total points possible. The calculator sums all points and shows your overall percentage and letter grade.
What Do I Need? tab: Enter your completed assignments, then set your target overall grade and the point value of your next assignment. The calculator tells you the exact score you need to reach your goal.
Both tabs share the same assignment list, so you can switch between them without re-entering data. Hit Share to save a URL with your entries.
Required Score = Target% × (Current Possible + Next Max) − Current Earned
Example: Target 90%, current 229/270, next assignment is 100 pts
= 0.90 × (270 + 100) − 229 = 333 − 229 = 104 pts needed
(Not achievable — would need over 100% on a 100-point assignment)
Practical Example
Situation: You have 229/270 points (84.81%). Your next assignment is worth 50 points. You want a 90% overall.
Needed = 0.90 × (270 + 50) − 229 = 288 − 229 = 59 pts out of 50
Result: You need more than 50 points, which isn't possible. Consider targeting 85% instead — you'd need only 0.85 × 320 − 229 = 272 − 229 = 43 out of 50 (86%).
Frequently Asked Questions
The Grade Calculator also does points-based grading but focuses on the current snapshot. The Assignment Grade Calculator adds the "What Do I Need?" feature specifically for planning your score on an upcoming assignment, which makes it a more active planning tool for students during the semester.
If your class uses weighted categories (e.g., "exams count 40%"), use the Grade Calculator's Weighted Average tab instead. This calculator works with raw point totals, which naturally weight assignments by their point value — a 100-point exam has twice the impact of a 50-point quiz.
The calculator will show a value above 100%, which means the target isn't achievable on that one assignment alone. Options: lower your target grade slightly, check if extra credit is available, or ensure you still have multiple graded items remaining in the semester where you can accumulate more points.
The score field accepts decimal values. If you received 8.5 out of 10, enter 8.5 in the score field and 10 in the max field. The calculator handles decimals correctly in all calculations.
Each calculator instance tracks one class. Open separate browser tabs — one per class — and use the Share button in each to save bookmarkable links. That way you can quickly return to each class's grade tracker without re-entering data.
