About the Final Grade Calculator
The Final Grade Calculator answers the question every student asks before exam week: what do I need on the final? Type your current grade in the course, the grade you want to end with, and how much the final is worth, and the calculator shows the score you need on the final exam. A table underneath gives the score needed for an A, a B, a C and a D at the same time, so you can see at a glance which grades are within reach. A second mode works out a weighted grade from categories such as homework, quizzes and exams; it has its own page, the Weighted Grade Calculator.
The calculator never treats a hard answer as an error. If you would need more than 100%, it says that you would need extra credit. If you would keep your target even with a 0 on the final, it says the grade is secured.
How to use it
Steps
- Type your Current grade (%), the percentage you have before the final.
- Type the Grade you want (%), for example 90 for an A.

Frequently asked questions
How do I work out what I need on my final?
Use needed = (target − current × (1 − w)) / w, where w is the final's weight as a decimal. With 82% now, a target of 80% and a final worth 25%, you need (80 − 61.5) / 0.25 = 74%.
What if the calculator says I need more than 100%?
Then the target cannot be reached with the final alone unless the final allows extra credit. Check the lower grades in the table to see which ones are still within reach.
What does secured even with a 0 mean?
Your current grade is high enough that you keep that letter grade even if you score nothing on the final. It assumes the final is the only work left and the weights are as entered.
Where do I find my final's weight?
Look in the course syllabus or grading policy, which usually lists each component as a percentage, such as homework 20%, midterm 30% and final 25%. Ask your teacher if it is not listed.
