Grade Calculator

Calculate what you need on your final exam.

Current Grade (%)

Desired Grade (%)

Final Weight (%)

Σ The Formula

Final Score Needed = (Target - Current × (1 - Weight)) / Weight

Real World Examples

Passing Grade

Current: 75%, Desired: 80%, Final Weight: 20% → Need 100% on final

Maintaining A

Current: 92%, Desired: 90%, Final Weight: 25% → Need 82% on final

Realistic Goal

Current: 85%, Desired: 88%, Final Weight: 30% → Need 95% on final

Already There

Current: 95%, Desired: 90%, Final Weight: 20% → Need 65% (already achieved!)

# About This Calculator

Finals week is stressful enough without guessing what score you need. The Grade Calculator uses your current grade and the weight of your final exam to tell you the exact minimum score needed to reach your target.

This tool answers the classic panic question: "Can I still get an A?" or, more desperately, "What do I need to just pass?"

How Grading Weights Work

Most college courses use a weighted system. For example:

Homework/Quizzes: 40%
Midterm: 30%
Final Exam: 30%

If you have a 95% going into the final, that only accounts for 70% of the total grade. The remaining 30% is completely determined by one test. This is why a bad final can drop an A to a B, or why a great final can save a failing grade.

Safe Buffer Strategy

Always aim for 2-3 points higher than the calculator says. If it says you need an 88%, aim for a 91%. This buffer protects you against tricky questions or harsh grading curves.

How To Use

Enter your **Current Grade** (e.g., 85%).
Enter your **Desired Grade** (e.g., 90% for an A).
Enter the **Weight** of the final exam (e.g., 20%).
Click **Calculate** to see the required score.

Frequently Asked Questions

What if it says I need > 100%?+

Unfortunately, this means it is mathematically impossible to reach your desired grade without extra credit. You should adjust your goal (e.g., aim for a B instead of an A) or talk to your professor immediately.

Does this work for midterms?+

Yes! Treat the 'Final Weight' as the weight of whatever big assignment or test is coming up. The math is identical.

How do I find the weight of my final?+

Check your course syllabus. It is almost always listed under 'Grading Policy' or 'Course Requirements'. It typically ranges from 15% to 40%.

What if my class uses points instead of percentages?+

Convert to percentage first. (Points You Have / Total Points Possible) * 100 = Current Grade %. Then use that percentage in this calculator.
