Introduction
This grade percentage calculator helps you find your overall grade in a class. Enter your assignments, grades, and weights, and the tool does the math for you. It works with percentage grades, letter grades, or a mix of both. You can also customize the grading scale to match the one your school uses.
The calculator has two modes. The Weighted Grade Calculator lets you combine assignments that count for different amounts of your final grade, like homework, tests, and projects. The Simple Test Grader lets you enter the total number of questions on a test and how many you got wrong. It then shows your score and letter grade along with a full grading chart.
You will also get a step-by-step breakdown of how your weighted average is calculated. This makes it easy to check your work or understand how each assignment affects your final grade. Plus, the built-in "What grade do I need?" tool tells you exactly what score you need on your next assignment to reach your target grade.

What Is a Grade Percentage?
A grade percentage is a number that shows how well you did on your schoolwork. It tells you how many points you earned out of the total points possible. For example, if you got 45 out of 50 on a test, your grade percentage is 90%.
How Weighted Grades Work
Not all assignments count the same in most classes. A final exam usually counts more than a single homework assignment. This is called weighting. Each assignment gets a weight that shows how much it matters toward your final grade. A project worth 30% of your grade has more impact than a quiz worth 5%.
To find your weighted grade, you multiply each assignment's score by its weight, add those results together, then divide by the total weight. The number you get is your overall grade percentage.
Letter Grades and Grade Scales
Schools use letter grades like A, B, C, D, and F to rank how well you did. Each letter matches a range of percentages. In most standard grade scales, an A starts at 93%, a B at 83%, a C at 73%, and so on. Some schools use slightly different cutoffs, which is why it helps to know your school's exact scale. If you need to convert your percentage into a GPA value, use our percentage to GPA calculator.
Why Your Grade Percentage Matters
Knowing your current grade percentage helps you plan ahead. You can figure out what score you need on your next test or project to reach the grade you want. If your goal is a B+ and you currently have an 82%, you can calculate exactly how well you need to do on upcoming work to get there. To see how individual class grades roll up into your overall GPA, or to plan out an entire semester grade, our dedicated tools can help.
Tips for Tracking Your Grades
- Enter grades as you get them. This keeps your grade average up to date so there are no surprises at the end of the term.
- Check that your weights add up to 100%. If they don't, your calculated grade may not match what your teacher reports.
- Focus on high-weight assignments. Doing well on a final exam worth 30% will raise your grade much more than acing a homework worth 5%.
