How to use this grade calculator

Type each assignment's score and max points. Your grade appears as a percent and a letter while you type.

Enter a Score and a Max for each assignment. The Score box also takes 18/20 or 90%.
Under "Match your class", pick your Grading scale. The default 10-point scale comes from Florida law for public grades 6 to 12, so check it against your syllabus.
Check "My teacher rounds .5 up" if yours does.

Every point counts the same here. If your syllabus weights homework, quizzes and exams, use the Weighted Grade Calculator.

How to find your grade percentage

Add the points you earned, divide by the points possible, and multiply by 100. The grade percentage calculator above does this for you.

Grade % = points earned ÷ points possible × 100

Made-up example: you have 18/20, 42/50, 9/10 and 85/100. That is 154 points out of 180, so your grade is 85.56%. On the 10-point scale, that is a B.

Bigger assignments move the number more. Made-up example: a 9/10 and a 60/100 make 69/110, or 62.73%, not the 75% you get by averaging 90 and 60.

How to average letter grades

Turn each letter into grade points, add them, and divide by the number of grades. This calculator takes numbers, not letters, so do this by hand.

Made-up example: A, B, B and C on the 10-point scale. That is (4.0 + 3.0 + 3.0 + 2.0) ÷ 4 = 3.0, a B.

Minus grades differ by school. A- is 3.7 at the University of Missouri and 3.67 at the University of Illinois. If your classes have different credits, use the GPA Calculator.

What your next assignment could do to your grade

Use the "What if I score..." box as a what if grade calculator. Enter the score and its Max points, and you see your new grade. Your rows stay as they are.

Made-up example: you have 154/180, or 85.56%. An 18/20 lifts you to 86%. A 0/20 drops you to 77%, a C.

It tests one score at a time. For a final exam, press "Plan my final" to open the Final Grade Calculator.

Missing, excused and extra-credit work

A blank score stays out of your grade. A 0 counts. Made-up example: 8/10 plus a blank 10-point assignment is 80%. With a 0 on it, you fall to 40%.

Open a row's ⋯ menu to change how it counts:

"Missing: counts as 0" adds the full Max with no points earned.
"Excused: does not count" takes the row out of your grade.
"Extra credit" adds your points but not the Max, so a made-up 90/100 plus 5 extra points is 95%.

Missing always means 0 here. Canvas's optional Missing Submission policy can award part of the points: 20% of a 10-point assignment gives 2. If your class does that, type the score.

Why this may not match your gradebook

Your gradebook shows a lower grade

Your gradebook may count ungraded work as zero. Check "Count work not graded yet as zero" and compare. Canvas's gradebook export has both views: Current ignores unsubmitted work, and Final counts it as zero. Weights can also make a low exam cost more.

Your gradebook shows a higher grade

Your teacher may have excused work, dropped a low score or added extra credit. Canvas leaves excused work out of the total and can drop a group's lowest scores. This tool has no drop option. To test one, use the Weighted Grade Calculator with one category at 100%.

The gap is under a point

Look at rounding. We show two decimals, and your gradebook may show fewer. Rounding can change the letter too: 89.5 is a B on the 10-point scale until you check "My teacher rounds .5 up". That box changes the letter, not the percent.

What real schools do: points or categories

Your syllabus decides. The US has no national standard, and a 2005 U.S. Department of Education overview says classroom teachers typically decide grades. With categories, each group gets a weight. Canvas puts weights on assignment groups, not single assignments.

Schools do publish letter cutoffs, and they differ:

A 92 is an A under Florida's law for public grades 6 to 12, and an A- in the Johns Hopkins School of Nursing table.
A 72 is a C at the University of the Incarnate Word, and a C- at Johns Hopkins nursing.
A 62 is a D under Florida's law, but falls below the 65 line on College Board's BigFuture table.

Grade calculator FAQ

Can I use this as a grade average calculator?

Yes. It adds up points, so a 100-point test counts ten times as much as a 10-point quiz. To count each assignment the same, type each score as a percent and leave Max blank.

Is an average grade calculator the same as a weighted one?

No. In general, an average grade calculator treats every point alike, and a weighted one gives each category a set share of the course. If your syllabus lists weights, use the Weighted Grade Calculator.

Is this a letter grade calculator too?

Yes. It puts a letter next to your percent, using the scale you pick or one you build on the Grading Scale page. It does not turn letters into a percent.

Is there a quick grade calc for one score?

Yes. Type 18/20 in the first Score box and you get 90%.
