Grade Calculator
Compute your current weighted course grade from graded categories, and find out what score you need on remaining work to hit a target grade.

Summary
With 60% of the course graded so far, the current grade is 84.42% (B). To reach 90% overall, an average of 98.38% is needed on the remaining 40% of the course.

What is a Grade Calculator?
A grade calculator computes your overall course grade from weighted categories — homework, quizzes, midterms, a final exam, and so on — each contributing a percentage of the total grade. Since most courses don't weight every assignment equally, simply averaging your scores gives the wrong answer; this calculator multiplies each category's score by its weight before combining them.
It also solves the reverse problem many students actually care about: given your current grades and a target overall grade, what average score do you need on the remaining (not-yet-graded) categories to reach that target?
Category Breakdown
| Category | Weight | Score |
|---|---|---|
| Homework | 20% | 92% |
| Quizzes | 15% | 85% |
| Midterm | 25% | 78% |
| Final Exam | 40% | not yet graded |
How a Weighted Grade Is Calculated
Only categories with an entered score count toward the current grade — the calculator divides by the weight of graded work only, not the full 100%, so an ungraded final exam doesn't unfairly drag your current grade toward zero before it's even been taken.
Solving for "What Do I Need on the Final?"
To hit a target overall percentage, the calculator first computes the total points already earned (weight × score, summed across graded categories), then figures out how many more points are needed to reach the target, and divides that by the remaining ungraded weight. If the result exceeds 100%, the target is no longer mathematically achievable no matter how well you do on what's left.
Why Ungraded Work Isn't Counted as Zero
Some grade calculators default missing scores to zero, which makes a current grade look artificially low before all assignments are complete. This calculator instead normalizes only over the weight of work that's actually been graded — a more honest picture of "how am I doing on what's been scored so far," while still letting the "needed on remaining work" figure show the full picture of what's left.
Standard Letter Grade Scale
This calculator uses the common US 13-tier scale: A+ (97–100), A (93–96), 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). Many instructors use their own scale (some skip +/- grades, some set different cutoffs), so always check your syllabus for the exact grading scale your course uses.
Example — Your Current Inputs
With 60% of the course graded so far, the current grade is 84.42% (B). To reach 90% overall, an average of 98.38% is needed on the remaining 40% of the course.
Additional Example — Chasing an A-
A student has Homework (20% weight, scored 95%), Quizzes (15%, scored 88%), and a Midterm (25%, scored 82%) graded so far — 60% of the course complete. Their current grade is (20×95 + 15×88 + 25×82) ÷ 60 ≈ 88.5%, a B+. With a Final Exam worth the remaining 40% and a target of 90% (A-) overall, they'd need (90×100 − 5,310) ÷ 40 ≈ 92.25% on the final — a demanding but achievable target.
About These Parameters
- Category, Weight, Score
- Each row represents one graded component of the course (homework, quizzes, exams, participation, etc.). Weight is that category's share of the final grade in percent — all weights should add up to 100%. Leave Score blank for anything you haven't been graded on yet.
- Target Overall Grade
- The final percentage you're aiming for. If any category is still ungraded, the calculator solves for the average score needed across that remaining weight to hit the target exactly.
Frequently Asked Questions
What if my weights don't add up to exactly 100%?
Weights totaling less than 100% are treated as the full grading scheme — the calculator uses whatever weights you enter as the complete picture. If they exceed 100%, an error is shown since that indicates a data-entry mistake (weights over 100% aren't mathematically valid for a single course).
Why is the "needed on remaining" percentage sometimes over 100%?
That means your target grade is no longer mathematically reachable — even a perfect 100% on everything left wouldn't be enough to bring the overall average up to your target, given how the already-graded work has gone.
Does this replace checking my school's actual grading policy?
No — always confirm the exact category weights and letter-grade cutoffs from your syllabus or instructor. Grading schemes vary widely (some drop your lowest quiz score, some curve exams, some don't use +/- grades at all), and none of those policy-specific adjustments are modeled here.
How is this different from the GPA Calculator?
This calculator finds your grade within a single course from its individual weighted assignments. The GPA Calculator instead combines final letter grades across multiple courses, weighted by each course's credit hours, to compute a semester or cumulative GPA.
