📚 Free Grade Calculator

Our free grade calculator helps you compute your weighted average score across multiple assignments, exams, and projects. Simply enter each assignment name, your grade percentage, and its weight toward your final grade. The tool instantly calculates your overall weighted score and converts it to a letter grade (A, B, C, D, or F). Whether you are a student tracking your progress during the semester or a teacher calculating final grades, this weighted grade calculator saves time and reduces errors. All calculations run in your browser — no data is uploaded anywhere.

The grade average calculator uses the standard weighted average formula:

For each assignment, your grade percentage is multiplied by its weight. All weighted scores are summed, then divided by the total weight. If your weights add up to 100%, the denominator is simply 100. The result is your overall percentage score.

Letter Grade Conversion

1. Enter assignment details — For each row, type the assignment name, your grade percentage (0-100), and its weight toward the final grade.
2. Add or remove rows — Use the “Add Row” button to include more assignments, or click the ✕ button on any row to remove it.
3. Check your weights — Ensure your weights add up to 100% for accurate results. The tool works with any total but weights totaling 100% is the standard.
4. Click Calculate Grade — The tool shows your overall percentage score and corresponding letter grade.

What is a weighted grade?

A weighted grade means that different assignments contribute different percentages toward your final grade. For example, a final exam worth 40% of your grade has more impact than a homework assignment worth 10%. Thisweighted grade calculatorautomatically accounts for these varying weights.

What if my weights don't add up to 100%?

The calculator still works correctly — it divides by the total weight entered. However, weights that sum to 100% produce the most intuitive results. If your syllabus shows weights that don't total 100%, double-check with your instructor.

Can I use this for GPA calculation?

This tool calculates overall percentage and letter grade. For GPA calculation on a 4.0 scale, try ourGPA Calculator, which handles semester and cumulative GPA computation.

Use this grade calculator throughout the semester to track your progress, not just at the end. By knowing your current weighted average, you can determine what scores you need on remaining assignments to achieve your target grade. For example, if you have an 82% going into a final exam worth 30% of your grade, you can calculate the minimum exam score needed to finish with an A. This strategy helps you set realistic goals and prioritize your study time effectively. For semester GPA planning, pair this tool with our GPA Calculator.
