Final Grade Calculator

This tool will determine what grade (percentage) you need on your final exam in order to get a certain grade in a class.

Your current grade is %.

Your grade was % before.

You got a % on the final.

Your final is worth % of your grade.

Question: My final counts as a test. What do I need to get?

If your final is in the “tests” category, then your overall grade will be affected by your current test average and how many tests you’ve taken so far.

Your current grade is %.

You want (at least) a % in the class.

Tests are worth % of your grade.

You have taken tests already.

Your test average is %.

The final is worth tests.

Question: There are 2+ parts in my final. What do I have to get on them?

If your final has multiple parts and you’ve finished some of them, then you can calculate what you need on the remaining parts. Your current grade should not include any part of your final.

Your current grade is %.

You want (at least) a % in the class.

Your final is worth % of your grade.

You have parts to your final.

On part 3, you got points.

On part 4, you got points.

On part 5, you got points.

On part 6, you got points.

On part 7, you got points.

Question: My class has a point system. How much is the final worth?

You can calculate how much your final is worth by dividing the number of points in your final by the total number of points.

Including the final, there are points possible.

Your final is worth points.

Question: My lowest test grade is dropped. What do I need to get?

Your overall grade depends on how low your lowest test grades are. If your final replaces your lowest test grade, then tell the calculator that your lowest 1 test is dropped and your final also counts as 1 test.

Your current grade is %.

You want (at least) a % in the class.

Tests are worth % of your grade.

Your have taken tests already.

Your test average is %.

Your lowest tests are dropped.

Lowest test grade was %.

2nd lowest test was %.

3rd lowest test was %.

4th lowest test was %.

5th lowest test was %.

6th lowest test was %.

7th lowest test was %.

8th lowest test was %.

Your final also counts as tests.

Your final is also worth % of your grade.

How does this work?
Most class grades are made up of several categories: homework, classwork, tests/quizzes, and the final exam. Usually, each category is worth a percentage of your overall grade. But because your final exam isn't scored until the very end, it isn't included when calculating your current overall grade. Instead, all the other categories are scaled up to consume the weight reserved for the final exam. Therefore, you can calculate the minimum grade you need to score on the final exam using the formula:

Required = (Goal − Current × (100% − Final Weight)) / Final Weight

See the formula sheet for an explanation of this formula and other formulas used in this calculator. It's not rocket science, it's just math! You could, of course, do this on any calculator, but you're here on RogerHub because it's cool. (:

I need more help!
Try one of the different calculator modes listed above. The advanced mode handles many different kinds of situations, such as:

  • If you have more tests and homework before the final
  • When your final counts as a test grade
  • Dropping the lowest test grades
  • Makeup assignments or test retakes
  • Extra credit
  • Missing assignments

If none of those options answers your question, feel free to ask your question in the comments section below.

Mon, 27 Jan 2020 03:16:29 GMT

Seeing that the worst it could get is a 60% is comforting. I can’t study since I get so anxious that I almost throw up but things are gonna be okay in the end. My exam is tomorrow, and after that my second semester is fun as hell. I’m gonna be okay.

mrs heiberger is the worst math teacher to grace this planet

Sun, 26 Jan 2020 19:53:58 GMT

Well boys its been an honour

Sun, 26 Jan 2020 19:44:30 GMT

Ok so I have this math teacher who lies about grades and doesn't explain things but wonders why the entire class is failing. So I need a 103.8% on the final to pass right now.

Sun, 26 Jan 2020 04:23:31 GMT

Whether you've taken the final already or will take it in a few days, you can do this. A random stranger on the internet believes you. As long as you keep working hard, a miracle isn't always out of the question.

10th grader
Sun, 26 Jan 2020 00:59:38 GMT

So just to clear things up

There's a specific 11th grader in the comments section telling 10th graders to 'die' and 'shut up and wait to be a junior before u complain' because, apparently, only juniors take AP classes that actually matter

I don't know where this kid is coming from, but I'm taking 4 AP classes this year and trust me, I'm pretty sure they matter

Also, I live in America and, despite having not the greatest president of all time, one of the key themes we believe in is freedom of speech. Don't tell people to shut up.

Fri, 24 Jan 2020 22:02:21 GMT

stop reading these comments and GO STUDY

Fri, 24 Jan 2020 20:43:40 GMT

so uh, i had a 72% in my class
i missed 6 supportive assignments (each worth 15% of my grade)
what will my new grade be?
then i took a test and got an 80% on it
what will be my new overall grade for the class?
i need answers because if i forget about this i might fail the class

Roger: Are you sure they’re each worth 15% of your grade? Because then those 6 assignments would add up to 90% of your grade.
