A grade calculator is a tool that helps students determine their scores on assignments, exams, and entire courses. Instead of manually crunching numbers or guessing where you stand, a grade calculator gives you instant, accurate results so you can focus on what matters — improving your performance.
Whether you need to find your percentage on a test, compute a weighted course average, or figure out exactly what score you need on a final exam, this tool covers all three scenarios in one place.
Enter your total questions and wrong answers to see your percentage and letter grade immediately.
Combine homework, quizzes, and exams with different weights to get your true course average.
Know exactly what score you need on your final to hit your target grade — no surprises.
Getting your grade takes just a few seconds. Here's how each tab works:
Enter the total number of questions and how many you got wrong. The calculator instantly shows your percentage score and corresponding letter grade with a full breakdown table.
Add each assignment with its score and weight (e.g., homework 20%, midterm 30%). The tool computes your overall weighted average automatically as you type.
Enter your current grade, the weight of your final exam, and your desired overall grade. The calculator tells you the minimum score you need on the final to reach your goal.
Make sure you enter assignment weights exactly as listed in your course syllabus. Even small differences — like counting participation as 5% instead of 10% — can shift your final grade significantly.
Most schools in the United States use this common grading scale. Your institution may vary slightly, so always confirm with your syllabus.
Grade calculators aren't just for finals week. Here are the most common scenarios where this tool saves time and stress:
Quickly convert raw scores to percentages and letter grades.
See where your overall average stands halfway through the semester.
Calculate the exact score needed on your final to hit your target GPA.
Monitor if your grades meet scholarship or financial aid requirements.
Ensure your cumulative average meets minimum degree thresholds.
Focus effort on the assignments that carry the most weight in your grade.
You're taking a biology course with: Homework (20%), Midterm (30%), Lab Reports (15%), and Final Exam (35%). Your scores so far are 88, 76, and 92 respectively. You want at least an 85% overall.
Result: You need at least an 88.9% on your final exam to finish with an 85% overall. Use the Final Grade tab above to run your own numbers.
It uses standard mathematical formulas identical to what your professor uses. Results are as accurate as the numbers you enter.
The default scale follows the standard US system (A = 90–100, B = 80–89, etc.). Some schools use plus/minus variations.
Use the Weighted Average tab to combine scores from different assignments within one course. For multiple courses, calculate each separately.
The Final Grade calculator works with any weight percentage. Just enter the actual weight of your final as listed in your syllabus.
