Select Calculate Grade (or press Enter) to see your percentage and a general letter-grade reference, together with the points or weighting included in the calculation.
Which mode should I use?
Match the calculator to your grading system
Points Mode
Use this when your results are recorded as points, such as 42 out of 50 on a test or 18 out of 20 on an assignment.
Weighted Mode
Use this when assessments have different weighting, such as assignments worth 30%, a midterm worth 25% and a final exam worth 45%.
Check your course grading rules before calculating. Some schools and institutions use categories, dropped scores, bonus marks, different weighting methods or specific rounding rules. Use the grading information supplied by your teacher, school, course or institution whenever it differs from a simple points or weighted-grade calculation.
Calculation Method
How the Grade Calculator works
The calculation depends on how your assessments are graded. Points Mode combines the points you earned, while Weighted Mode accounts for how much each assessment contributes to your grade.
Add your points together
Points Mode compares the total number of points you earned with the total number of points that were available.
Formula
Example: three assessments
Account for assessment weighting
Weighted Mode gives each assessment the influence specified by its percentage weighting rather than treating every assessment equally.
Formula
Example: three weighted assessments
If the assessments entered account for less than 100% of the course, the calculator normalises the entered weights to show your current average across the work included so far.
Weighted grades are not always calculated the same way
Some courses calculate grades using weighted assessment categories, dropped scores, bonus marks, minimum requirements or other rules. Always compare the method used here with the grading policy provided by your teacher, school, university or course.
Understanding Your Result
What does your grade percentage mean?
Your calculated percentage shows your performance across the assessments included in the calculation. How that percentage translates into a letter grade, pass level or academic classification depends on the grading system used by your school, university or course.
Start with the percentage
The percentage is the calculator’s primary result. It is based directly on the points or weighted grades you entered and is generally more useful than assuming a particular letter-grade system.
Your calculated grade is 82.1%
Using the weighted example from the section above, the assessments included produce an overall result of 82.1%. The academic meaning of that result should be interpreted using the grading rules that apply to your course.
Percentage result
This is the mathematical grade calculated from the assessment information you entered.
Letter grade
The A–F result in the calculator is a general reference and may not match the grading boundaries used by your institution.
Passing grades
Do not assume a particular percentage is a pass. Minimum passing grades can differ between subjects, courses and institutions.
Rounding rules
Your institution may round grades differently or calculate final results using greater precision than the displayed percentage.
Use your institution’s official grading scale
If you need to determine whether a result corresponds to a particular letter grade, pass level, distinction, GPA value or other academic classification, check the official grading policy for your school, university, course or education system. The percentage calculated here does not replace an official academic result.
Choosing the Right Method
Points vs weighted grades
The right calculation method depends on how your course awards marks. Points Mode works from points earned and points possible, while Weighted Mode accounts for assessments that contribute different percentages toward the overall grade.
Use Points Mode when…
Your assessments are recorded as a number of points earned out of a number of points available.
- Your test result is shown as something like 42 points out of 50.
- Assignments can have different maximum point values.
- Your overall result is calculated from total points earned compared with total points available.
You earn 45/50 on one assessment and 72/100 on another. Together, you have earned 117 points out of 150, giving an overall grade of 78%.
Use Weighted Mode when…
Different assessments or categories contribute different percentages toward your final course grade.
- Your syllabus says an assignment is worth 20% of your final grade.
- Tests, projects and exams have different levels of importance.
- You want to calculate your current average from the weighted assessments completed so far.
If assignments are worth 30%, a midterm 25% and a final exam 45%, each result must be multiplied by its weighting before the contributions are combined.
Quick Decision Guide
Not sure which mode to choose?
Look at the way your teacher, syllabus, gradebook or institution describes your assessment results.
Do not mix points and weighting unless your grading system does
A high-point assessment is not automatically the same as a high-weight assessment. For example, a 100-point test could still represent only 20% of a course grade. Follow the grading method specified by your teacher, school, university or course.
Avoid Common Errors
Common grade calculation mistakes
Grade calculations are usually straightforward, but a small input or interpretation error can change the result. Check these common issues before relying on your calculated percentage.
Averaging percentages that should use points
Two assessments with different maximum point values should not automatically be treated as equally important.
If your course is points-based, add all points earned and all points possible before calculating the percentage.
Ignoring assessment weights
An exam worth 40% of a course should not be treated the same as a quiz worth 10% simply because both have percentage scores.
Use Weighted Mode when your course specifies how much each assessment or category contributes to the overall grade.
Confusing points with weighting
A 100-point assignment is not necessarily worth 100% or even more than a smaller assessment in the final course grade.
Treat point values and percentage weights as separate concepts unless your course instructions explicitly connect them.
Assuming entered weights must total 100%
If some assessments have not yet been completed, the grades you currently know may represent only part of the full course weighting.
The calculator can show your current average across the weighted assessments entered, while also showing how much weighting remains.
Assuming one letter-grade scale applies everywhere
Grade boundaries vary between education systems, institutions, courses and sometimes individual subjects.
Use the calculated percentage first, then compare it with the official grading scale that applies to your course.
Forgetting special grading rules
Some courses drop the lowest score, offer bonus marks, use category weighting or require a minimum result on a particular assessment.
Review your syllabus, gradebook or official course rules before treating a simple calculated percentage as your final result.
Before You Calculate
A quick grade accuracy check
Taking a few seconds to verify the information you enter can prevent the most common calculation errors.
Your official grade may still differ
This calculator works from the information you enter. Your official result may differ if your school, university, teacher or course applies rules that are not included in those inputs, such as dropped assessments, extra credit, penalties, category weighting or specific rounding procedures.

Grade Calculator FAQs
Find answers to common questions about calculating grades, weighted assessments, points, letter grades and interpreting your results.
How do I calculate my overall grade?
If your course uses points, add together all of the points you earned, divide that total by all of the points possible, and multiply by 100. For example, earning 136 points out of 170 possible gives an overall percentage of 80%.
If your assessments have different percentage weightings, use Weighted Mode instead.
What is the difference between points and weighted grades?
Points Mode calculates your grade from the total points earned compared with the total points possible. Weighted Mode accounts for how much each assessment contributes to the overall grade.
For example, a final exam may be worth 40% of your course even if the exam itself contains 100 points.
What happens if my assessment weights total less than 100%?
When the weights you enter total less than 100%, this calculator normalises those entered weights and shows your current average across the assessments included. It also shows how much of the full 100% weighting remains.
For example, if completed assessments represent 60% of the course, the result reflects your average across that completed 60% rather than treating the remaining 40% as a score of zero.
Can I use this calculator for university or college grades?
Yes. You can use the calculator for school, college, university or other courses when the grade can be calculated using points or percentage weightings.
However, institutions can use different grading systems, assessment rules, grade boundaries and rounding methods. Always compare the calculated result with the official rules for your course.
Why might my official grade be different from the calculator?
Your official result may include rules that a basic points or weighted calculation does not capture. These can include dropped scores, bonus marks, penalties, category weighting, minimum assessment requirements or specific rounding procedures.
The calculator works only from the information you enter, so your institution’s official gradebook or course rules should be treated as authoritative.
What letter grade is 80%?
In the general reference scale used by this calculator, 80% corresponds to a B. The reference scale is A for 90% and above, B for 80% to under 90%, C for 70% to under 80%, D for 60% to under 70%, and F for below 60%.
This is only a general reference. Letter-grade boundaries are not universal, so check the grading scale used by your school, university or course.
Can I calculate what grade I need on my final exam?
For that calculation, use our Final Exam Grade Calculator. It is designed to calculate the exam score needed to reach a target overall course grade when you know your current grade and the weighting of the final exam.
Check your official course rules
Grading systems differ between institutions and courses. Use this calculator to perform the mathematics from the information you enter, then compare the result with your syllabus, gradebook or official grading policy.
Methodology
How we calculate your grade
The Grade Calculator uses standard arithmetic based entirely on the scores and weightings you enter. The calculation method changes depending on whether you choose Points Mode or Weighted Mode.
Total earned ÷ total possible
Points Mode adds together the points earned for all included assessments and compares them with the combined number of points possible.
Grade × assessment weight
Weighted Mode multiplies each entered grade by its percentage weighting, adds the weighted values together and divides by the total weighting entered. If your weights add up to less than 100%, the result is your average across the work entered so far.
What the calculator does
Uses your inputs
The calculation is based on the assessment scores, points and weightings that you enter into the calculator.
Applies the selected formula
Points Mode uses total points, while Weighted Mode accounts for the percentage contribution of each entered assessment.
Shows the percentage
The result is rounded to two decimal places and shown with a general A–F letter-grade reference to make it easier to interpret.
Important calculation limitations
The calculator does not automatically know the grading rules used by your school, university, teacher or course. Your official grade may use category weighting, dropped assessments, extra credit, penalties, minimum assessment requirements, special pass rules or a particular rounding method. Where your course uses additional rules, follow the official grading policy for that course.
General letter-grade reference
The calculator uses the following A–F scale only as a general reference. It is not presented as a universal grading standard.
