How to use this final grade calculator

Enter your current grade, the final's weight and your goal. You see the score you need, plus the score for every letter.

  1. Type your Current grade, like 87.5 or 250/300. Points are exact, so use them.
  2. Add the Final exam weight % from your syllabus.
  3. Type a Goal %, or choose one under "Or pick a letter".

Use your grade before the final counts. We assume the final is your last work and one score out of 100%. If your final also replaces your lowest test, the tool has a box for that, explained below. Other special rules are not covered.

How to calculate the grade you need on your final

Take your goal, subtract what your current grade already gives you, and divide by the final's weight.

Score needed = (goal − current × (1 − weight)) ÷ weight

Made-up example: your current grade is 88.3, the final is 15% (0.15), and your goal is 90.

(90 − 88.3 × 0.85) ÷ 0.15 = 99.6333...

We round that up to 99.64%, because rounding down misses. A 99.6 gives 88.3 × 0.85 + 99.6 × 0.15 = 89.995, which is under 90.

The score you need for every letter grade

The "Score needed for each grade" table shows every letter at once. Made-up example: a current grade of 84 and a 20% final on the 10-point scale.

GradeMinimum percentScore needed
A90%114%, with bonus points only
B80%64%
C70%14%
D60%Reached even with a 0
F0%Reached even with a 0

Pick Plus/minus scale under "Match your class" for all 13 rows. Check "My teacher rounds .5 up" and each line drops half a point, so an A starts at 89.5.

Final exam calculator examples with real numbers

All three are made-up examples.

  • With 92 going in, a 30% final and a goal of 90, you need 85.34%.
  • With 95 going in, a 10% final and a goal of 80, you reach your goal even with a 0.
  • With 92 going in and a 30% final, a 60 leaves you at 82.4%, a B.

If the score you need is over 100%

Then a final out of 100 cannot get you there without bonus points. Made-up example: with 80 going in, a 20% final and a goal of 90, you would need 130%. A perfect 100 leaves you at 84%.

If you see About 100%, your typed grade is rounded. Made-up example: a typed 83.33 with a 25% final and a goal of 87.5 needs 100.01%. The exact 250/300 needs 100%.

Why this may not match your gradebook

Made-up example: you have 596 of 700 points, a 300-point final is open, and your goal is 85.

Your gradebook shows a lower grade

Your gradebook may be counting the final as zero, like the Final score in Canvas's gradebook export. That shows 59.6%, but your current grade is 85.14%. Type 59.6 with a 30% final and you are told 144.27%. Type 85.14 and you get 84.68%.

Your gradebook shows a higher grade

Look for a dropped score, excused work or bonus points you left out. Canvas can drop a group's lowest scores. If your final shares a category with other tests, its real weight differs from what you typed.

The gap is under a point

Your typed grade is rounded. The exact 596/700 needs 84.67%, not 84.68%, so type your points, or press "Plan my final" on the Grade Calculator or Weighted Grade Calculator, which sends them for you. If your teacher rounds the course grade, check "My teacher rounds .5 up".

What real schools do: how finals count

Your syllabus sets the final's weight. We have no source for a typical one. The US has no national standard, and a 2005 U.S. Department of Education overview says classroom teachers typically decide grades.

Schools do publish the lines you must clear:

  • Florida's law for public grades 6 to 12 sets F at 0 to 59.
  • Johns Hopkins nursing programs require a repeat below C- (70%) in the five-semester MSN Entry into Nursing, and below B- (80%) in MSN Specialty Tracks.
  • The same school rounds final course grades to a whole number, so 89.5 becomes 90, an A-.

If your final replaces your lowest test

Some courses count the final twice: once on its own, and once in place of your lowest test when that helps. A University of Houston MATH 1314 letter to students describes this, and a Georgia Tech MATH 1551 syllabus works out the grade both ways and keeps the higher one.

Check "My final also replaces my lowest test score if it is higher" in the tool, then enter your test scores, what all tests are worth together, and your grade in everything else. Made-up example: homework of 90% worth 30%, tests of 72, 85 and 90 worth 50% together, and a 20% final. For a 90 in the course you need 92.28% on the final, and it replaces the 72. Without the rule you would need 109.17%.

Other courses use other rules. A Georgia Tech ISYE syllabus replaces all three exams when the final beats their average, and University of Kentucky General Chemistry swaps one exam for the matching section of the final. The tool does not cover those, and it treats every test as worth the same. Check your syllabus.

Plan the rest of your term

If more than the final is open, use the Weighted Grade Calculator. It gives the average you need across everything left, unless a Lowest percent drop covers open work.

To see the effect on your GPA, open the GPA Calculator. Its Target box shows what you need next term. Then read How to Raise Your GPA.

Final grade calculator FAQ

What grade do you need to pass a class?

It depends on your school. In Florida public grades 6 to 12, the grade needed to pass is 60, since F ends at 59. Stanford calls D a minimal pass. Johns Hopkins nursing programs ask for C- or higher. Made-up example: a 52 with a 25% final needs 84% to reach 60.

How do I calculate my final grade after the exam?

Multiply your current grade by 1 minus the weight, then add your exam score times the weight. Or type your score in "If I score this on the final".

How do I find the final's weight in a points class?

Divide its points by the course's total points. In the made-up example above, 300 of 1000 is 30%.

What if my final has several parts?

We treat the final as one score out of 100%. Combine the parts into one percent first.
