Grade Calculator
Calculate your weighted or unweighted grade average with this grade calculator. See your letter grade, progress bar, and what you need on the final.
About Grade Calculator
Keeping track of your grades throughout the semester helps you plan ahead and avoid surprises. This grade calculator supports both weighted and unweighted modes so it works for any class structure.
Weighted and Unweighted Modes
Switch between modes with a single click. In weighted mode, each assignment or category has a percentage weight (for example, exams worth 40%, homework worth 30%). In unweighted mode, every assignment counts equally toward your average.
Dynamic Assignment Entry
Add or remove rows as needed. For each assignment, enter a name, your score as a percentage, and (in weighted mode) the weight. The calculator updates your average and letter grade in real time as you type, with a progress bar showing where you stand.
What Score Do I Need?
The built-in target calculator works backward from your desired final grade. Enter your target percentage and the remaining weight, and it tells you the minimum score needed on upcoming work. If the number is over 100%, you will know right away that the goal is out of reach.

Frequently Asked Questions
How does weighted grading work?
Weighted grading assigns a percentage weight to each assignment or category (for example, homework 20%, midterm 30%, final 50%). Your grade is calculated by multiplying each score by its weight, summing those products, and dividing by the total weight. This means higher-weighted items have more impact on your final grade.
What is the letter grade scale used here?
This calculator uses the standard US scale: A+ (97-100), A (93-96), A- (90-92), B+ (87-89), B (83-86), B- (80-82), C+ (77-79), C (73-76), C- (70-72), D+ (67-69), D (63-66), D- (60-62), and F (below 60).
How does the \"What score do I need\" feature work?
Enter your desired final grade and the remaining weight (or number of assignments in unweighted mode). The calculator works backward to determine the minimum score you need on the remaining work to achieve that target. If the required score is over 100%, it means the target is not achievable with the remaining weight.
What is the difference between weighted and unweighted mode?
Weighted mode lets you assign a percentage weight to each assignment, so some count more than others toward your final grade. Unweighted mode treats every assignment equally and simply averages all the scores together.
Can I use this for college courses?
Yes. Most college courses use weighted grading, so enter each assignment category with its weight from the syllabus. For cumulative GPA calculations across multiple courses, use the GPA Calculator tool instead.
