What is my final grade?
Your grade is usually made of a few pieces that do not count equally — coursework, a midterm, a final exam.
If coursework counts for 40 and the exam for 60, scoring 70 and 80 gives you 76 — not the 75 you would get by averaging them.
Put in at least one score and how much it counts, and your grade will show up here.
How to calculate a final grade
A course grade is usually made of several pieces that do not count equally — coursework, a midterm, a final exam. Each one is worth a share of the total.
Put in what you scored on each piece and how much of your grade it is worth, and we weigh them properly. Add as many pieces as your course has.
Why averaging gives the wrong answer
If coursework counts for 40 and the exam for 60, scoring 70 and 80 does not give you 75. It gives you 76, because the exam you did better on carries more of the grade.
The gap grows the more uneven the weightings are. It is the single most common mistake people make working out their own grade.
Common questions
How to calculate final grade step by step?
List each piece of work with the score you got and how much of your grade it is worth, and we do the weighing.
By hand: multiply each score by its weighting, add all of those together, then divide by the total of the weightings.
What is 70% of your grade?
It is a weighting, not a score. If a course says the final exam is 70% of your grade, it means 70 of every 100 points in your final result come from that one exam, and the remaining 30 come from everything else put together.
So the exam matters more than twice as much as the rest. Scoring 90 on coursework worth 30% and 60 on an exam worth 70% gives an overall 69, much closer to the exam mark than to the coursework one.
Put each piece in with its weighting and you will see how much each one is actually pulling.
How is overall grade calculated?
Each piece of work is worth a share of the total, and your overall grade is those shares added together.
Take each score, multiply it by its weighting, add all of those results, then divide by the total of the weightings. With coursework of 70 worth 40 and an exam of 80 worth 60: 70 times 40 is 2800, 80 times 60 is 4800, and 2800 plus 4800 divided by 100 is 76.
The weightings normally add up to 100. If yours do not, the running total on this page will show it, and something is probably missing.
What is the formula for grade?
Overall grade equals the sum of each score multiplied by its weighting, divided by the sum of the weightings.
Written out: (score1 × weight1 + score2 × weight2 + …) ÷ (weight1 + weight2 + …).
When the weightings already add up to 100, the division step is just dividing by 100, which is why the formula is often written without it.
How can I calculate a grade?
It depends which grade you mean, and there are three separate questions people ask.
If you have marks out of a total and want a percentage, use the marks to percentage calculator. If you have several pieces of work that count for different amounts and want the overall result, use this one. If you have one exam left and want to know what you need on it, use the final exam calculator.
Why can I not just average my scores?
Because averaging assumes every piece counts the same, and they usually do not.
Scoring 70 on coursework worth 40 percent and 80 on an exam worth 60 percent gives 76, not the 75 an average would suggest.
What if my weightings do not add up to 100?
We still give you a grade for the pieces you entered, and tell you what they add up to so you can see something is missing.
A running total is shown as you type, so you can check it reaches 100 before trusting the final figure.
Can I add more than three pieces of work?
Yes. Use the add button for as many as your course has, and remove any you do not need.
