When to use a grade calculator
What is my grade right now? A grade calculator answers that for one class, from the scores you already have, whether your syllabus weights categories (Homework 15%, Exams 30%) or adds up points (45/50). Use it mid-term to see where you stand, before a test to see what it could do, and before finals to plan the score you need.
Combining several classes? That takes credits, so use the GPA Calculator.
How to use the grade calculator
Have your latest scores and your syllabus grading breakdown ready. A grade can be a percentage (92), points (45/50) or a letter (B+).
- Enter your assignments or categoriesFor a points class, add each assignment as its own row. For a weighted class, add each category, such as Homework, Quizzes or Exams, with its current average. Name is optional, and + Add grade adds rows.
- Add scores and weightsType each score under Grade. If your syllabus weights categories, put each percentage under Weight on every row. If your class adds up total points, enter scores as points, like 45/50, and leave every Weight blank.
- Check your resultYour grade updates as you type. Pick your class’s scale in Options under Grading scale. Your work saves on this device, and Save this calculation keeps the class so you can update it after the next assignment.
Common mistake
Enter a category’s average or the assignments behind it, not both. Entering both counts that work twice.
Use an exact percentage or points when you have them. A letter counts as the middle of its range, so B+ becomes 88%. Not sure what to type? Try sample scores fills in an example.
How to raise your grade
Put your effort where it moves your grade most. Here’s where all 100 course points stand in the biology class (85.14%, a B):
Every class is worth 100 course points, split by weight: homework at 15% is worth 15. Points lost are the part your score missed: 92% on homework earns 13.8 of its 15 points and loses 1.2.
| Category | Worth | Score | Earned | Lost |
|---|---|---|---|---|
| Homework | 15 | 92% | 13.8 | 1.2 |
| Quizzes | 20 | 84% | 16.8 | 3.2 |
| Labs | 15 | 88% | 13.2 | 1.8 |
| Midterm | 20 | 79% | 15.8 | 4.2 |
| Final | 30 | — | — | — |
| Total | 100 | 59.6 | 10.4 |
- Ace what’s still open. The 30-point final outweighs every point you’ve lost so far combined.
- Fix your biggest leak. Ask about midterm corrections or a retake: 10 more points on it lifts you from 85.14% to 88%, a B+.
- Turn in everything. A missing assignment counts as a zero: one 50-point quiz drops you to 80.34%.
- Test it before it happens. Add your expected score as a row, or tap Plan my final exam for the exact score you need.
What do you need on the final?
Best grade still possible: 89.6%, a B+, and only with 100% on the final. Each final score lands you here:
| Score on the final | Final class grade | Letter grade |
|---|---|---|
| 100% | 89.6% | B+ |
| 85% | 85.1% | B |
| 70% | 80.6% | B− |
| 50% | 74.6% | C |
| 0% | 59.6% | F |
Need a B+? That takes 91.4% on the final (the calculator rounds up so you don’t fall short). Keeping the B takes 78%.

How to calculate your grade
To calculate your grade in a class that weights categories:
- Multiply each category’s score by its weight.
- Add those results together.
- Divide by the total weight graded so far.
If your class adds up points instead, divide the points you earned by the points possible (below).
Formula
Current grade = sum of (category score × weight) ÷ sum of the weights graded so far
Say your biology syllabus weights Homework 15%, Quizzes 20%, Labs 15%, the Midterm 20% and the Final exam 30%. The final hasn’t happened yet, and your quiz average is 168 of 200 points, or 84%:
| Category | Score | Weight | Points | ||
|---|---|---|---|---|---|
| Homework | 92% | 15% | 13.8 | ||
| Quizzes | 84% | 20% | 16.8 | ||
| Labs | 88% | 15% | 13.2 | ||
| Midterm | 79% | 20% | 15.8 | ||
Weighted points 59.6 Weight graded 70% Current grade 85.14% | |||||
The graded categories cover 70% of the course, so 59.6 ÷ 0.70 = 85.14%, a B on the standard scale. Dividing by the full 100% would treat the ungraded final as a zero and show 59.6%, which is why grades early in a term can look scary.
If your class adds up points instead
A points class skips the weights: your grade is total points earned ÷ total points possible × 100. A 45/50 quiz and an 80/100 test give 125 ÷ 150 = 83.33%.
The test counts twice as much as the quiz because it’s worth twice the points. Averaging the two percentages, 90% and 80%, gives 85%, which treats them as equal and won’t match a total-points gradebook. To check it, enter 45/50 and 80/100 and leave Weight blank.
What your grades mean
Your result shows the grade, its letter and its grade points, here 85.14%, a B, worth 3.0. Letters follow the standard plus/minus scale below; Options also has a 10-point scale (A 90, B 80, C 70, D 60).
| Band | Letter grade | Percentage | Grade points |
|---|---|---|---|
| Excellent | A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 | |
| A− | 90–92% | 3.7 | |
| Good | B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 | |
| B− | 80–82% | 2.7 | |
| Average | C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 | |
| C− | 70–72% | 1.7 | |
| Low pass | D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 | |
| D− | 60–62% | 0.7 | |
| Fail | F | Below 60% | 0.0 |
A D (63–66%) still passes on this scale, since an F starts below 60%, but some programs ask for a C or better in certain courses. Type a letter instead of a score and the calculator uses the middle of its range, so a B+ counts as 88%.
Test scores as percentage grades
To turn a score into a percentage, divide what you earned by what it was out of, then multiply by 100. So 12 out of 15 is 12 ÷ 15 × 100 = 80%, a B−. You can also type a score straight into the Grade box as 12/15.
These are the scores students look up most often:
| Score | Percentage | Letter grade |
|---|---|---|
| 12/15 | 80% | B− |
| 25/30 | 83.33% | B |
| 10/13 | 76.92% | C |
| 30/50 | 60% | D− |
| 11/20 | 55% | F |
| 12/14 | 85.71% | B |
| 12/20 | 60% | D− |
| 20/30 | 66.67% | D |

Why your gradebook may disagree
Your result matches your gradebook when the scores, weights and rounding match. If they don’t, start from what you see:
- Lower than here? A missing assignment probably counts as a zero. Enter it as 0 out of its points: one missing 50-point quiz takes the biology grade from 85.14% to 80.34%.
- Much lower early in the term? Your gradebook may count ungraded work, like the final, as a zero. Leave it out here; the grade on the weight graded so far is the real one.
- Higher than here? Your lowest score may have been dropped, or extra credit added. Remove the dropped score’s points, and enter a bonus as a score over the original total, like 23/20.
- A point or two off? Your teacher may count every assignment equally instead of adding points. Enter each score out of 100 and leave Weight blank: an 18/20, 82/100 and 47/50 give 88.67% this way and 86.47% by points.
- Less than a point off? That’s rounding or hidden decimals. Check the cutoff: 89.5% is a B+ here and an A− only if your teacher rounds up.
Tip
Canvas: if your class weights assignment groups, the sidebar on your Grades page lists each group’s weight. PowerSchool: teachers pick total points or category weighting; if your portal doesn’t show the weights, they’re in your syllabus. Copy each category’s percentage and weight here to check your grade.

Frequently asked questions
Is a D a passing grade?
On the standard scale, yes: a D (63–66%) and even a D− (60–62%) sit above the 60% line where an F starts, so they pass the class. Some programs require a C or higher in certain courses, so check your school’s rules before counting on a D.
What is a what-if grade calculator?
It shows what your grade would be after scores you haven’t earned yet. In this calculator, add the score you expect as a new row, read the new grade, then delete it or swap in the real score. Plan my final exam does the same for your final.
What percentage is a B?
A B is 83–86% on the standard plus/minus scale, with B+ at 87–89% and B− at 80–82%. On a 10-point scale with no plus or minus, any score from 80% to 89% is a B.
How do you calculate weighted grades?
Multiply each category’s average by its weight, add the results, and divide by the total weight graded so far. With Homework 92% at 15%, Quizzes 84% at 20%, Labs 88% at 15% and a 79% midterm at 20%, that’s 59.6 ÷ 0.70 = 85.14%.
How do you calculate a grade percentage from points?
Divide the points you earned by the points possible, then multiply by 100. A 42 out of 50 is 42 ÷ 50 × 100 = 84%, a B on the standard scale.
How do you turn a letter grade into a percentage?
Use the middle of the letter’s range. On the standard scale a B+ (87–89%) counts as 88%, which is what this calculator does when you type a letter instead of a score.
What percentage is an A?
An A is 93–96% on the standard scale, with A+ at 97–100% and A− at 90–92%. On a 10-point scale, every score from 90% up is an A.
What grade is 12 out of 15?
12 out of 15 is 80%, because 12 ÷ 15 × 100 = 80. That’s a B− on the standard plus/minus scale and a B on a 10-point scale.
How much will a 60 affect my grade if I have a 94?
It depends on how much the 60 counts. If it is worth 10% of your grade and the rest averages 94, you end at 94 × 0.90 + 60 × 0.10 = 90.6%; if it is worth 20%, you end at 87.2%. In a points class, use the assignment’s points instead of a percentage weight.
If I have a 90 and the final is worth 20%, what happens if I fail it?
A 0 on the final leaves you at 90 × 0.80 = 72%, a C−. A 50% on the final lands you at 82%, a B−, and you need at least 90% on the final to keep a 90.
