How Grade Calculation Works

Weighted Grade = Ξ£(Score% Γ— Weight) Γ· Ξ£(Weight) Unweighted Grade = Ξ£(Score%) Γ· Number of Entries

Calculation Components

Score Obtained: The actual marks or points you received on an assignment, exam, quiz, or project. For example, 42 out of 50 on a midterm exam.
Maximum Score: The total possible marks for that assessment. This could be 100, 50, 25, or any value set by your instructor or institution.
Score Percentage: Calculated as (Score Obtained Γ· Maximum Score) Γ— 100. This normalizes all scores to a common percentage scale for comparison.
Weight (Weighted Mode): The importance or contribution of each assessment to the final grade. For example, finals might be 40%, midterm 30%, assignments 20%, and participation 10%.
Letter Grade: The alphabetical representation of your percentage score based on standard grading scales (A+, A, A-, B+, B, etc.).

For example, if Rohit from IIT Delhi scored 85 out of 100 on his midterm worth 30% and 92 out of 100 on his final exam worth 50%, and 78 out of 100 on assignments worth 20%, his weighted grade would be calculated as: (85Γ—30 + 92Γ—50 + 78Γ—20) Γ· (30+50+20) = (2550 + 4600 + 1560) Γ· 100 = 87.10%. This gives him a B+ letter grade. The weighted calculation ensures the final exam has the highest impact on his overall grade, which accurately reflects the course structure.

Grade Calculation Examples

πŸŽ“ Priya's Engineering Semester

Input: Midterm: 72/100 (25%), Final: 88/100 (40%), Labs: 45/50 (20%), Assignments: 85/100 (15%)

Result: 81.95% β€” B- Grade

Use Case: Priya from NIT Trichy calculates her weighted grade to check if she can maintain her 8+ CGPA this semester.

Input: Quiz 1: 18/25 (10%), Quiz 2: 22/25 (10%), Project: 38/50 (30%), Viva: 9/10 (10%), Exam: 68/100 (40%)

Result: 74.80% β€” C Grade

Use Case: Meera from Mumbai University checks her internal marks before the final university exam to plan her study strategy.

What is a Grade Calculator?

A Grade Calculator is an educational tool that helps students compute their overall course grade based on individual assignment scores, exam marks, and their respective weights. Whether you are studying at an Indian university, preparing for board exams, or attending college internationally, understanding your current grade helps you make informed decisions about your study priorities and academic goals.

This free online Grade Calculator supports both weighted and unweighted grading systems. In weighted mode, each assessment component carries a specific percentage weight that reflects its importance β€” for instance, a final exam typically weighs more than a weekly quiz. In unweighted mode, all assignments are treated equally and a simple average is calculated. This flexibility makes the tool suitable for virtually any educational institution and grading structure.

Students across India β€” from IIT and NIT students tracking their semester performance, to CBSE and ICSE students estimating their board exam averages, to college students monitoring internal assessment marks β€” can benefit from this calculator. The tool provides instant percentage calculations, automatic letter grade conversion, and a visual breakdown of each score. Built with expertise in educational assessment methodologies, this calculator delivers reliable results that match what teachers and professors compute using official grade books. All processing happens locally in your browser, ensuring your academic data remains completely private and secure.

Frequently Asked Questions

Yes, this Grade Calculator is completely free to use without any charges, subscriptions, or hidden fees. You can calculate grades for unlimited assignments, exams, and projects. There are no premium features locked behind a paywall. Every function including weighted grading, letter grade conversion, and result copying is available to all users at no cost whatsoever.
Absolutely. Your academic data is completely safe and private. This Grade Calculator runs entirely in your web browser using client-side JavaScript. No grades, scores, assignment names, or any personal information is ever sent to any server, stored in any database, or shared with any third party. When you close or refresh the page, all entered data is permanently gone from memory.
This Grade Calculator is highly accurate as it uses standard mathematical formulas for weighted and unweighted averages. The weighted average formula divides the sum of score-times-weight products by the total weight, which is the same method used by universities and schools worldwide. Results are calculated to two decimal places for precision. The calculator also validates all inputs to prevent errors.
Unweighted grades treat all assignments equally by computing a simple average of all scores. Weighted grades assign different importance to each component. For example, a final exam might count for 40% of your grade while homework counts for 20%. Weighted grading reflects that some assessments matter more than others. Most colleges and universities in India and abroad use weighted grading systems.
To calculate a weighted average, multiply each assignment score percentage by its weight, sum all these products, and divide by the total weight. For example, if you scored 85% on an exam worth 50% and 90% on homework worth 30%, the weighted calculation would be (85Γ—50 + 90Γ—30) Γ· (50+30) = (4250+2700) Γ· 80 = 86.88%. Our calculator automates this entire process for you instantly.
Yes, this Grade Calculator works perfectly with Indian university grading systems. Whether your institution uses percentage-based grading, CGPA conversion, or weighted internal and external assessment marks, you can input your scores and weights accordingly. Indian universities like Delhi University, IITs, and state universities all use weighted grading for internals, practicals, and theory exams which this tool handles seamlessly.
This calculator uses the widely accepted standard letter grading scale: A+ for 97-100%, A for 93-96%, A- for 90-92%, B+ for 87-89%, B for 83-86%, B- for 80-82%, C+ for 77-79%, C for 73-76%, C- for 70-72%, D+ for 67-69%, D for 63-66%, D- for 60-62%, and F for below 60%. This scale is commonly used in American and many international educational institutions.
Yes, you can add unlimited assignments, exams, quizzes, projects, or any other graded components. Simply click the Add Assignment button to create new entry rows. There is no maximum limit on the number of entries. You can also remove any entry by clicking the remove button next to it. This flexibility allows you to calculate grades for entire semesters with many components.
The calculator handles this gracefully. In weighted mode, it divides the weighted sum by the actual total weight entered, not necessarily 100%. So if your weights add up to 80%, it will correctly calculate based on those 80% of weights. However, for the most accurate final grade representation, your weights should ideally sum to 100%. The calculator displays the total weight so you can verify.
While this calculator computes your current grade based on completed assignments, you can use it to plan what you need on future exams. Enter your completed assignments with their scores and weights, then experiment with different scores for your upcoming exam to see how each scenario affects your final grade. This is a great way to set study goals and understand how much effort your final exam requires.
Yes, this calculator supports both percentage-based and point-based grading. For each assignment, you enter the score obtained and the maximum possible score. The calculator automatically converts these to percentages for computation. Whether your exam is out of 100, 50, 25, or any other maximum, the calculator handles the conversion accurately and displays results as percentages.
Yes, this Grade Calculator is fully responsive and works perfectly on mobile phones, tablets, and desktop computers. The interface automatically adapts to your screen size with touch-friendly buttons and appropriately sized input fields. You can calculate your grades on-the-go using your smartphone browser without needing to install any app. It works on all modern browsers including Chrome, Safari, and Firefox.
