What is the US grading scale?

The standard US grading scale: A = 90-100% (excellent); B = 80-89% (good); C = 70-79% (average); D = 60-69% (passing); F = below 60% (failing). With +/- modifiers: A+ ≥ 97, A 93-96, A− 90-92, B+ 87-89, B 83-86, B− 80-82, and so on. Universities often use a 4.0 GPA scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus/minus adds 0.3 each side (A− = 3.7, B+ = 3.3). High schools and colleges sometimes weight honors/AP/IB courses on a 5.0 scale.

What is the UK grading scale?

UK undergraduate honours degree scale: First Class (1st) — 70% and above; Upper Second (2:1) — 60-69%; Lower Second (2:2) — 50-59%; Third Class (3rd) — 40-49%; Fail — below 40%. UK GCSE/A-Level use a 9-1 numerical scale (replaced A*-G in 2017): 9 = top, 1 = lowest pass. Grades 7-9 correspond roughly to old A and A* grades. Boundaries shift each year based on cohort performance — they're not fixed percentages.

What is the AP grading scale?

AP (Advanced Placement) exam scores use a 1-5 scale: 5 = Extremely well qualified; 4 = Well qualified; 3 = Qualified; 2 = Possibly qualified; 1 = No recommendation. Most US colleges grant credit for scores of 3 or higher, but the most selective universities (Ivy League, MIT, Stanford) often require 4 or 5 for credit. Each AP score corresponds to roughly the equivalent college course grade: 5 ≈ A, 4 ≈ B+, 3 ≈ C. The College Board publishes the percentage of students earning each score annually.

How is grade percentage calculated with weights?

Multiply each category's grade by its weight, then sum and divide by total weights (which should sum to 100% or 1). Example: Homework 20%, Midterm 30%, Project 20%, Final 30%. Grades: HW = 85, MT = 78, Proj = 92, Final = 80. Weighted average = (85×0.20 + 78×0.30 + 92×0.20 + 80×0.30) = 17 + 23.4 + 18.4 + 24 = 82.8. So overall grade is 82.8% = B. Different weights produce different results — always check the syllabus.

What Is a Grade Calculator?

A grade calculator computes your weighted average grade from multiple assignments, quizzes, tests, and exams. Each assignment can have a different weight reflecting its importance in your final grade. This tool helps you track your current standing in a course and plan how to achieve your target grade by understanding how each component contributes to your overall score.

Weighted Grade Formula

The weighted average formula calculates your grade based on each component's contribution:

Weighted Grade = Σ(Score × Weight) ÷ Σ(Weight)

Where Score is the percentage earned on each assignment and Weight is the relative importance assigned to that component. The denominator is the sum of all weights included in the calculation.

Example Calculation

Example: Calculating Course Grade

Assignments:

• Homework (weight: 20): 92%

• Midterm Exam (weight: 30): 78%

• Project (weight: 15): 88%

• Final Exam (weight: 35): 85%

Calculation:

Weighted Sum = (92×20) + (78×30) + (88×15) + (85×35) = 1840 + 2340 + 1320 + 2975 = 8475

Total Weight = 20 + 30 + 15 + 35 = 100

Final Grade = 8475 ÷ 100 = 84.75%

Letter grade conversions depend on your course's specific grading scale.
Some instructors drop lowest scores—factor this in when entering grades.

Calculate My Grade With Weights

This grade calculator works as a quick grade calc, a calculate my grade helper, a grade weight calculator, and a grade average calculator. Add each assignment, quiz, exam, or project with its score and weight, and the tool shows the weighted grade without making you rebuild the gradebook in a spreadsheet.

How to Calculate My Grade

List each graded item, enter the score you received, and add the weight from your syllabus. The calculator multiplies each score by its weight, adds the weighted scores, and divides by the total weight. That gives the current course grade or grade average.

Assignment: 92 at 20% weight.
Midterm: 78 at 30% weight.
Project: 88 at 15% weight.
Final: 85 at 35% weight.

Grade Weight Calculator - Custom Percentages

Many courses do not weight every item equally. Homework may be 20%, tests 50%, projects 15%, and participation 15%. This grade weight calculator lets those percentages stay exactly as your teacher or professor wrote them.

Grading Calculator for Teachers and Students

Students can check whether their online gradebook looks right. Teachers can use the same grading calculator to test a syllabus, model grade categories, or explain why a heavily weighted final changes the course result so much.

Grade Average Calculator vs Final Grade

A grade average calculator tells you where you stand from completed work. A final grade calculator tells you what score you still need on the final exam. Use this page for current weighted average, and use the final grade page when the remaining exam is the main question.

Grade Weight Average Calculator

A grade weight average calculator is useful when your class grade is not a simple average. Quizzes, homework, labs, projects, and exams may each carry a different share of the final mark. Enter the score for each item and its weight, then use the weighted result as your current course average.

If the weights you know do not add to 100 yet, calculate the completed work first and treat the answer as your grade so far. Add the missing exam or project later when the score is available.

Weighted Grade Calculator Online

A weighted grade calculator online is most useful when the weights do not add to 100 yet. You can enter only completed work to estimate the grade so far, then add remaining assignments later as they are graded.

Frequently Asked Questions

How do I calculate my grade with this grade calculator?▼

Enter each assignment, quiz, project, or exam with its score and weight. The calculator multiplies scores by weights and combines them into a weighted grade average.

What is a weighted grade?▼

A weighted grade gives more influence to high-value work. A final exam worth 40% affects the course grade much more than a quiz worth 5%.

Can I use this as a grading calculator for teachers?▼

Yes. Teachers can enter grade categories and weights to check a course setup or explain grade outcomes to students.

What is the difference between grade average and final grade?▼

Grade average usually means your current average from completed work. Final grade means the course grade after all remaining work, including the final exam, is counted.

What is 70% of a grade?▼

A 70% grade usually means you earned 70 out of every 100 marks. Formula with values: Let A = marks obtained and B = total marks. Percentage = (A / B) x 100. If A = 70 and B = 100, percentage = (70 / 100) x 100 = 70%. In CBSE-style bands, 61-70 may be B2, while in some U.S. scales 70% can be C-. Grade names change by institution, so compare the percentage with your official chart.

What grade is an A+?▼

A+ is the highest grade in many systems, but the percentage band changes. Value check: Let A = your percentage. In many U.S.-style charts, A+ may require B = 97-100%. In CBSE-style school grading, the highest band A1 is often C = 91-100 with grade point D = 10. If A is inside the top band, it may be called A+ or A1. The safe method is: calculate percentage first, then compare it with the official grade table.

Is a 90% grade an A?▼

A 90% grade is usually an A-range score, but the exact letter depends on the grading chart. Formula with values: Let A = 90 and B = grade boundary. If your school says A = 90-100, then A = 90 is an A. If it uses CBSE-style bands, 90 may be A2 while 91-100 is A1. If a U.S. chart says A- = 90-92, then 90 is A-. The percentage is strong; the letter name must follow your official scale.

Is a 75 an A or B?▼

A score of 75 is usually not an A on most common grade charts. Value check: Let A = 75%. If your grading table has B = 70-79, then A falls in the B band. In CBSE-style bands, 71-80 is often B1, so 75 becomes B1. In some U.S. charts, 75 may be C or C+. Therefore, 75 is commonly B/B1 in Indian school bands, but not universally. Always compare it with the grade boundaries used by your institution.

Is a 78% an A or B?▼

A 78% is commonly a B-range grade, not an A, in many systems. Value check: Let A = 78%. If B = 71-80 is the B1 band, then A belongs to B1. If your school uses A = 90-100, then 78 is clearly below A. Some colleges may use different labels such as distinction, first class, or grade point. The method is simple: first calculate percentage, then locate it inside the official grade-band table.

Which grade is 82%?▼

An 82% score is usually a strong grade. Value check: Let A = 82%. In CBSE-style bands, B = 81-90 is often A2, so 82% falls in A2. In many U.S. charts, 82% may be B- or B, because A often begins near 90%. This shows why grade names are not universal. Use the formula Percentage = marks obtained / total marks x 100, then compare A with your school's grade chart.

What is the grade of 82%?▼

For 82%, the grade depends on the board. Formula with values: Let A = 82 and B = 100. Percentage = (A / B) x 100 = 82%. If the grade chart says 81-90 = A2, then 82% is A2. If another chart says 80-89 = B, then it is B. Therefore, the numerical percentage is fixed, but the grade name changes. Students should always mention the scale when comparing grades across schools or countries.

Is 69% A or B in India?▼

In many Indian school grade bands, 69% is usually B2 or a B-range grade, not A. Value check: Let A = 69%. If B = 61-70 is B2, then A falls in B2. If a college defines first class as C = 60% and above, 69% may be first class, but that is not the same as letter grade A. Grade letters differ by board, university, and course. Use the official grade table printed in your syllabus or marksheet.
