Grade Calculator

List the parts of the course, how much each is worth and what you scored. Two numbers come out: the grade you have so far, counted only on what has been marked, and what you would finish with if you handed in nothing else. Below that, the question most people actually came for — what you need on the rest.

List what the course is made of: each part, its weight in per cent and the score you got. Leave the score empty for anything not graded yet.

Grade so far —

Nothing leaves this tab: the marks are kept in this browser so they survive a reload, and they are not sent to a server. The letter grade uses the common American scale (93 is an A, 90 an A-, and so on); plenty of schools use different cut-offs, so check yours before trusting the letter.

How to use

  1. Put each part of the course on its own row: name, weight in per cent and your score in per cent.
  2. Leave the score empty for anything not marked yet. That is what separates the two answers below.
  3. Type the grade you are aiming for, and the page says what average you need on the remaining weight to get there.
  4. A new row appears as you fill the last one. The weights do not have to add up to 100 — if they do not, a note says what total is being used.

Good to know

«What I have now» and «what I will finish with» are different questions

Say homework is 40 % of the course and you scored 90 on it, and nothing else has been marked. Your grade so far is 90 %: it is counted only on the part that has been graded. But if you never hand in another thing, you finish with 36 %, because the other 60 % scores zero. Both numbers are true and both are useful — the first tells you how you are doing, the second tells you what is at stake. Calculators that show only one of them are answering half the question, and which half depends on who is asking. This page shows both, and the second only appears when it differs from the first.

Weight is not the same as count

Four homework assignments and one exam are five things, but they are not five equal things. If homework together is worth 40 % and the exam 60 %, then scoring 90 on homework and 60 on the exam gives 72, not the 75 you would get by averaging the two numbers. This is the arithmetic that makes people misjudge how much the final matters: with a 60 % exam, a perfect semester is worth less than an average exam. Enter the weights from your syllabus and the calculator does the rest.

When the target is out of reach, the number still helps

If you need 118 % on the final, the honest answer is that the grade is gone — but «118» is more useful than «impossible», because it tells you by how much. Needing 102 means one extra-credit assignment might do it; needing 140 means it is time to aim at the next grade down instead. The page gives the number either way and says plainly when it is above what a normal assignment can give.

Frequently asked questions

What do I need on the final exam?

Fill in what has been marked so far, leave the exam's score empty, and type the grade you want. The line below tells you the average you need on the remaining weight. If the exam is the only thing left, that number is exactly your required exam score.

My weights do not add up to 100. Is that a problem?

No, and the page will not silently fix it. Everything is counted against whatever the weights actually add up to, and a note tells you what that total is. That is usually what you want — courses often have parts you have not listed yet — but if the number surprises you, it is a sign to check the syllabus.

Can I enter a score above 100?

Yes. Extra credit that takes an assignment past full marks is common, and the calculator will not quietly take it away from you. It counts as entered, so a 110 on a piece of work pulls the average up exactly as much as it should.

Is the letter grade the right one for my school?

Maybe not. The letter uses the common American scale — 93 and up is an A, 90 an A-, and so on — but cut-offs vary between schools and even between departments. Use the percentage as the real answer and treat the letter as a rough guide until you have checked your own scale.

Are my marks sent anywhere?

No. They are kept in this browser so they are still there after a reload, and they are not sent to a server, shared between devices or visible to us. Clearing your site data removes them, and the page works offline.
