Grade Calculator
Find your current class grade from assignment and test scores — with weighted categories, drop-lowest rules, and the exact score you need on what is left. Built to match how your professor’s gradebook actually works.
Calculate Your Current Class Grade
Pick the mode that matches your syllabus. If your syllabus lists percentages (“Homework is 20% of your grade”), use Weighted Categories. If it lists raw points (“Homework is worth 200 points”), use Total Points.
Your Grade Breakdown
Every number below reflects only the work you have actually completed. Ungraded categories are excluded, not counted as zeros.
Grade Leverage — Where Your Study Time Actually Pays
This is the number almost no grade calculator gives you. Each bar shows the maximum number of percentage points that remaining item can still move your final grade. A 5%-weight quiz cannot save you. A 40%-weight final can rewrite the whole semester.
How to read this
An assignment’s leverage is capped by its weight. If a category is worth 10% of your grade, then even a perfect score versus a zero only swings your final number by 10 points — and realistically far less. Study time is a finite resource. Spend it on the tallest bar, not the loudest deadline.

How a Grade Calculator Actually Works
Almost every grading dispute I have seen between a student and a gradebook comes down to one misunderstanding: a weighted grade is not an average of your scores. It is an average of your scores after each one has been multiplied by how much it counts.
Here is the formula every professor’s spreadsheet is running behind the scenes:
The weighted grade formula
Current Grade = Σ(Score × Weight) ÷ Σ(Completed Weights)
Read that as: multiply each score by its weight, add them all up, then divide by the total weight of the work you have actually finished. That final division is the step most people skip — and it is the step that makes your number correct mid-semester.
Say your syllabus reads: Homework 20%, Quizzes 25%, Midterm 25%, Final 30%. You have finished homework (92%), quizzes (85%) and the midterm (78%). The final has not happened yet.
The wrong way — the way that quietly ruins people’s expectations — is to average 92, 85 and 78 and get 85%. The right way is to weight them: (92 × 20) + (85 × 25) + (78 × 25) = 1840 + 2125 + 1950 = 5915. Then divide by the completed weight, 70: 84.5%. Not a dramatic gap in this example, but on a semester where your lowest score sits in your heaviest category, that gap can be five or six full points — the difference between a B and a C.
Why your calculated grade does not match Canvas, PowerSchool, or Blackboard
This is the single most common question students ask, and the answer is almost never “the calculator is broken.” It is one of five things:
Some gradebooks are configured to treat unsubmitted assignments as zeros immediately; others exclude them until the due date passes. This calculator excludes them, which reflects your true standing on completed work.
If your professor drops the lowest quiz, the portal may already be showing you the post-drop number. Set the drop-lowest field above to match your syllabus.
Bonus points can be added to a category’s earned total, added to the overall percentage, or handled as a separate weightless line. All three produce different final numbers.
An 89.62% is a B+ in a strict-cutoff class and an A− in a rounding class. Same work. Different letter.
It happens more often than students expect, especially when an assignment gets cancelled and its weight is redistributed.
Weighted categories vs. total points: which mode do you need?
Read your syllabus and look at the language. If it says “Quizzes are 30% of your final grade,” that is a weighted-category course — use the first mode. If it says “Quizzes are worth 300 points out of 1,000 total,” that is a points-based course — use Total Points mode, and enter points earned and points possible directly. No conversion needed.
The two systems produce identical results when the proportions match. The reason we built both is that entering the wrong format is the fastest way to get a number that does not match your gradebook.
Does 89.5% round up to an A?
Mathematically, 89.5 rounds to 90. In practice, it depends entirely on your instructor, and there is no universal rule — even within a single university. Some syllabi state a cutoff of “90” (which implies 89.5 rounds up). Others state “90.0” (which implies it does not). Many professors round at their discretion for students who have shown consistent effort, and just as many hold a hard line.
The practical takeaway is not “hope for the round.” It is this: if you are inside half a point of a boundary, you are gambling with a decision that is not yours to make. The calculator above flags that danger zone explicitly, because the fix — a few extra points on any remaining assignment — is almost always cheaper than the appeal email.
How much can one assignment really change your grade?
Less than most students think, and this is genuinely liberating information. The impact of a single item is bounded by its weight:
Marginal impact formula
Grade change = (New Score − Current Average) × Weight ÷ 100
Score 95% on a 5%-weight homework when your average is 80%, and your grade moves +0.75 points. Score 95% on a 40%-weight final under the same conditions, and it moves +6 points. This is why panicking over a small assignment while under-preparing for the final is the most common — and most expensive — study error in academia.
Standard Letter Grade Scales
Three scales are supported above. Confirm which one your course uses — the same percentage can be two different letters depending on the scale.
| Letter | Plus / Minus | Standard 10-Point | Strict 7-Point | Typical GPA |
|---|---|---|---|---|
| A | 93 – 100 | 90 – 100 | 93 – 100 | 4.0 |
| A− | 90 – 92.9 | — | 90 – 92.9 | 3.7 |
| B+ | 87 – 89.9 | — | 87 – 89.9 | 3.3 |
| B | 83 – 86.9 | 80 – 89.9 | 85 – 86.9 | 3.0 |
| B− | 80 – 82.9 | — | 83 – 84.9 | 2.7 |
| C+ | 77 – 79.9 | — | 80 – 82.9 | 2.3 |
| C | 73 – 76.9 | 70 – 79.9 | 77 – 79.9 | 2.0 |
| C− | 70 – 72.9 | — | 75 – 76.9 | 1.7 |
| D | 60 – 69.9 | 60 – 69.9 | 65 – 74.9 | 1.0 |
| F | Below 60 | Below 60 | Below 65 | 0.0 |
A quick note on why this table matters more than it looks: a 76% is a solid C on a plus/minus scale, a C on a standard scale, and a C− on a strict 7-point scale. If your program requires a C or better to advance, that scale choice is not academic trivia — it decides whether you retake the course.
Frequently Asked Questions
Multiply each category score by its weight, add the results together, then divide by the total weight of the categories you have completed. For example, with homework at 92% (20% weight) and a midterm at 78% (25% weight), your current grade is [(92×20) + (78×25)] ÷ 45 = 84.2%. Dividing by completed weight instead of 100 is what makes the number accurate mid-semester.
Usually one of five causes: ungraded work is being counted as a zero in the portal, a dropped lowest score has already been applied, extra credit is placed in a different category than you assumed, rounding rules differ, or the syllabus weights were revised mid-term. Match your drop-lowest setting to your syllabus first — that resolves the majority of mismatches.
It depends on your instructor’s rounding policy, and there is no universal standard. Mathematically 89.5 rounds to 90, which would be an A−. But many syllabi state a hard cutoff at 90.0, meaning 89.5 stays a B+. Some professors round at their discretion; others never do. Check your syllabus, and if you are within half a point of a boundary, treat it as unresolved rather than won.
It removes that score entirely before the average is computed, which raises your grade — but by how much depends on the weight of the category, not just how low the score was. This calculator drops by weighted contribution, meaning it removes whichever item is actually costing you the most points, which is not always the numerically lowest score.
The maximum swing equals the assignment’s weight. A quiz worth 5% can move your final grade by at most 5 points, and realistically far less. A final exam worth 40% can move it by up to 40 points. Use the formula (New Score − Current Average) × Weight ÷ 100 to see the true impact before you decide where to spend your study hours.
That is completely normal mid-semester — it simply means some categories are not graded yet. This calculator normalizes automatically by dividing by the weight you have actually completed. If your weights exceed 100%, re-check your syllabus, because one category has likely been entered incorrectly.
If your teacher adds bonus points to a specific category, raise that category’s score above 100 (this calculator accepts scores over 100). If extra credit is a flat boost to your final percentage, calculate your grade normally and add it afterwards. Confirm which method your instructor uses, because the two produce different results.
Match your syllabus. If it expresses grading in percentages (“tests are 40% of your grade”), use weighted categories. If it expresses grading in raw points (“tests are worth 400 of 1,000 points”), use total points and enter points earned and points possible. Both produce the same result when proportions are equivalent — the difference is which format prevents entry errors.
Your ceiling is the highest possible final grade if you score 100% on every remaining assignment. Your floor is the lowest possible grade if you score 0% on everything left. Together they define the realistic range you are still playing inside — and if your target sits above your ceiling, it is mathematically out of reach and you should redirect your effort.
Yes. The weighted-average math is identical at every level — high school, community college, university, and graduate coursework. The only variable is your school’s letter-grade scale, which is why three scale options are provided above. For Honors and AP courses that carry additional GPA weight, use the Weighted GPA Calculator instead.
Yes, but enter your post-curve scores. A curve adjusts individual assessment scores before they enter the gradebook, so apply the curve to each affected score first, then let the calculator handle the weighting. Curves applied at the end of the semester to the final letter cutoffs cannot be predicted in advance.
No. A grade calculator computes your percentage inside one course. A GPA calculator converts your final letter grades across multiple courses into a 4.0-scale average. Use this tool during the semester, then feed the resulting letter grades into a GPA calculator once the term closes.
