About the The Math Calculator Menu section

This ever-growing math and algebra calculator collection began with many of the calculators I created to help me assist my own children with their mathematic and algebra homework.

From my experience, the authors of contemporary math textbooks seem more interested in showing how smart they are instead of providing detailed explanations that parents can understand.

Math Can Be Fun ... If You Enjoy Doing Math!

What you won't find in the online math calculators section is any of the normal hype you read on other math help sites. No matter how hard these sites try to convince parents and students that math can be made to be fun, for many, mathematics is not, nor will it ever be, fun.

In my opinion, the only people who consider math to be fun, are those who enjoy doing math -- people like myself. And while I consider certain types of math to be fun, other types ... not so much. The only reason I enjoy any type of math at all is that it helps me to solve problems that are important to what I enjoy doing.

As for those people who hate mathematics now and forever, the most one could hope to accomplish is to help them and their children to pass their required math courses in the least amount of time, with the least amount of stress -- which is my goal for the online math calculators section.

What is the Key to Being "Good at Math?"

The key to being good at math boils down to one skill -- memorization. That's all math is, the memorization of math facts, formulas, and rules. So if you're good at memorizing and retaining facts, formulas, and rules, you will most likely be good at math.

Unfortunately, no matter how good you are at memorization, if you don't use what you have memorized on a consistent basis, you will eventually forget what you once had memorized. And therein lies the problem for most parents when it comes to helping their children with their math and algebra homework -- the average parent has not used what they were taught as children often enough to retain what they now need to tutor their children.

Are You Pulling Your Hair Out Trying To Help Your Children With Math?

If you're a parent, and you've forgotten your math and algebra due to lack of use -- or you never had much of an aptitude for mathematics and algebra to begin with -- and you have a child who is struggling with mathematics, the math and algebra calculators in this section were designed with you in mind.

The math and algebra calculator collection in this section consists of calculators that will:

• Help in the memorization and retention of math facts, formulas, and rules.
• Make quick work of time consuming tasks, such as factoring.
• Quickly solve common types of problems, such as fractions, exponents, square roots, etc.

Please let me know if there's a calculator you would like to see added to this online math calculators section.

Help and Tools:

About: Click this tab for an introduction to this section.

Pocket Calc: Click this tab for a handy "pocket" calculator.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.

Brief history of different grading systems

In 1785, students at Yale were ranked based on "optimi" being the highest rank, followed by second optimi, inferiore (lower), and pejores (worse). At William and Mary, students were ranked as either No. 1, or No. 2, where No. 1 represented students that were first in their class, while No. 2 represented those who were "orderly, correct and attentive." Meanwhile at Harvard, students were graded based on a numerical system from 1-200 (except for math and philosophy where 1-100 was used). Later, shortly after 1883, Harvard used a system of "Classes" where students were either Class I, II, III, IV, or V, with V representing a failing grade. All of these examples show the subjective, arbitrary, and inconsistent nature with which different institutions graded their students, demonstrating the need for a more standardized, albeit equally arbitrary grading system.

In 1887, Mount Holyoke College became the first college to use letter grades similar to those commonly used today. The college used a grading scale with the letters A, B, C, D, and E, where E represented a failing grade. This grading system however, was far stricter than those commonly used today, with a failing grade being defined as anything below 75%. The college later re-defined their grading system, adding the letter F for a failing grade (still below 75%). This system of using a letter grading scale became increasingly popular within colleges and high schools, eventually leading to the letter grading systems typically used today. However, there is still significant variation regarding what may constitute an A, or whether a system uses plusses or minuses (i.e. A+ or B-), among other differences.

An alternative to the letter grading system

Letter grades provide an easy means to generalize a student's performance. They can be more effective than qualitative evaluations in situations where "right" or "wrong" answers can be easily quantified, such as an algebra exam, but alone may not provide a student with enough feedback in regards to an assessment like a written paper (which is much more subjective).

Although a written analysis of each individual student's work may be a more effective form of feedback, there exists the argument that students and parents are unlikely to read the feedback, and that teachers do not have the time to write such an analysis. There is precedence for this type of evaluation system however, in Saint Ann's School in New York City, an arts-oriented private school that does not have a letter grading system. Instead, teachers write anecdotal reports for each student. This method of evaluation focuses on promoting learning and improvement, rather than the pursuit of a certain letter grade in a course. For better or for worse however, these types of programs constitute a minority in the United States, and though the experience may be better for the student, most institutions still use a fairly standard letter grading system that students will have to adjust to. The time investment that this type of evaluation method requires of teachers/professors is likely not viable on university campuses with hundreds of students per course. As such, although there are other high schools such as Sanborn High School that approach grading in a more qualitative way, it remains to be seen whether such grading methods can be scalable. Until then, more generalized forms of grading like the letter grading system are unlikely to be entirely replaced. However, many educators already try to create an environment that limits the role that grades play in motivating students. One could argue that a combination of these two systems would likely be the most realistic, and effective way to provide a more standardized evaluation of students, while promoting learning.

Enter your assignment scores here to automatically calculate your current grade (e.g. midterms, homework, tests, labs, etc.)

Important Notes

You can use our grade calculator to calculate the final exam grade you will need to achieve the overall course grade you desire. Our calculator requires you to enter the current percentage grade you have currently obtained for that course together with the weight of the final exam as a percentage value. However, if you do not know what your current grade is, for the question "Do you know your Current Grade?" select the answer "no." Enter the grades you have received for all of your assignments, homework, test, labs, and anything else that contributes to your final grade, as well as the weight of each grade. Our grade calculator will automatically calculate not only your current grade but the grade you need to achieve on your final exam to achieve the overall course grade you desire. In addition, both the minimum and maximum course overall grades will be provided.

Once you have entered the information required, the system will generate both a table and a chart that show the different final exam grades you may obtain as well as the overall course grades that go with them.

Inputting Data in our Grade Calculator

When entering your current grade and the weight of your final exam, our calculator will assume that your current grade has been based on the weight of the course prior to your final exam and calculates it as the input weight subtracted from 100%. If your current grade hasn't taken your coursework into account, the generated results will not be accurate.

Similar to the above, if you don't know what your current grade is and you enter both the coursework grades and the associated weights into the calculator, the calculator will automatically calculate your current grade and the weight of the final exam. In this situation, the weight of your final exam is calculated by taking the sum of the weight of your course work subtracted from 100%. With that in mind, if you enter too many or not enough assignments, the weight of the final exam that is calculated will most likely not match the actual weight of the final exam in your chosen course.

• GPA calculator

Understanding how to calculate your current grade in a course is advantageous for planning what you need to achieve your goal’s overall course grade. The following Grade Calculator serves as an easy-to-use helpful tool to calculate your current grade of the course before the final examination.  

What is a Grade Calculator?  

A Grade Calculator is a free online tool designed to help students and educators determine academic grades based on entered scores and weights. It simplifies the process of calculating current grades, helping users navigate their academic journeys.   

The Grade Calculator helps students estimate the impact of each assignment on their course’s weighted average grade. That means the overall grade of a course depends on 2 main factors: the grade of each assignment (g) and the corresponding weight of each assignment (w).  

A Grade calculator helps you find your current average score in a course based on completed assignments up to the current point in the semester. The Final grade calculator then calculates the score you need to achieve in your remaining assignment (the final exam) to reach your desired grade of the course

How to Use a Grade Calculator?  

Using a Grade Calculator is a straightforward process that involves entering relevant information about your academic performance. To utilize this calculator, input your current percentage for each assignment, test, or exam, along with its respective weight towards your final grade. For each additional assignment, test, or exam, click on "Add Assignment." Your results will automatically update as you input each component , allowing you to track your progress throughout the course.  

Here's a step-by-step guide on how to use a Grade Calculator:  

Step 1: Input the Assignments.  

Users manually enter the name of each assignment, for example: Assignment 1, 2, 3, Homework, Final Exam, etc.  

Step 2: Input the grade.  

Enter their scores for each assignment, test, project, or other exam throughout the course. Each entry typically includes the earned percentage (10%, 30%, 50%, etc.), letter (A+, B-, D, etc.), or points (20, 50, 175, etc.).  

Step 3: Input the weight.  

Enter the weight of that assignment into the overall course grade. The weight indicates that different assignments may have varying impacts on the final grade. A final exam might have a higher weight than a small task.  

Step 4: Calculate the grade automatically.  

The tool then automatically calculates the cumulative grade based on the entered grades and weights. Users can see their current grade as well as how each assignment contributes to the overall grade.  

Step 5: Adjust as needed.  

Users can adjust grades or weights to see how changes impact the overall course performance. This dynamic feature allows for real-time exploration of different scenarios, helping users make informed decisions about their academic strategy and goal achievement.  

Weighted Grade Calculation: Formula and Example  

The calculation of a weighted grade involves summing the products of the weights (w) and the corresponding grades (g).  

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (g₁ + g₂ + g₃ +...)  

Example 1: Grade type: Percentage  

Determine the weighted grade of a course, in which:  

• Assignment with a grade (percentage) of 80 and a weight of 30.  
• Homework with a grade (percentage) of 90 and a weight of 20.  
• Final exam with a grade (percentage) of 72 and a weight of 50.  

The weighted average grade is determined by the formula:  

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (w₁ + w₂ + w₃+...)  

Substituting the values:  

Weighted Grade = (30 × 80 + 20 × 90 + 50 × 72) / (30 + 20 + 50) = 78  

Example 2: Grade type: Letter  

• Assignment 1 with a grade (letter) of A+ and a weight of 20.  
• Assignment 2 with a grade (letter) of B and a weight of 20.  
• Final exam with a grade (letter) of C- and a weight of 60.  

The weighted average grade of the course is calculated by the formula:

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (w₁ + w₂ + w₃ +...)  

Weighted Grade = (20 × 4.33 + 20 × 3.00 + 60 × 1.67) / (20 + 20 + 60) = 2.64   

The table below shows how your letter grades convert to a numeric grade (4.0 scale) and percentage grade (% scale):  

Example 3: Grade type: Point  

Consider the following case:  

• For Assignment 1, the grade is 60 out of 80.  
• For Assignment 2, the grade is 30 out of 50.  
• For Homework, the grade is 120 out of 120.  
• For the Final exam, the grade is 60 out of 100.  

The formula to calculate the weighted average grade is:  

Weighted Grade = sum of real grade / sum of maximum grade  

Weighted Grade = (60 + 30 + 120 + 60) / (80 + 50 + 120 + 100) = 77.14  

Important Role of the Grade Calculator in Academic Path  

The Grade Calculator functions as a flexible tool that aids both educators and students, fostering efficiency and transparency. Knowing the average grade is essential for strategic decision-making in scenarios and setting achievable academic goals.  

Scenario Planning:  

Some Grade Calculators allow users to experiment with different scenarios. For instance, students can input hypothetical scores for future assignments or exams to see how they would impact their final grade. This helps in understanding how adjustments to upcoming assessments may impact the overall class performance.  

Teachers can use a Grade Calculator to streamline the grading process. By inputting scores and weights, the tool can quickly calculate overall grades, saving time and ensuring accuracy.  

Goal Setting:    

Users can set grade goals and determine the scores needed on upcoming assessments to achieve those goals. This application is particularly helpful for students who aim for a specific final course grade. Goal-setting helps students set realistic academic goals and understand the scores needed to achieve them. Knowing their current grade and having the ability to plan for future assessments can reduce stress for students.  

The Grade calculator provides the average score for a specific course. Students can use this result to calculate their GPA, which represents the average score across all their courses. In essence, the output from the Grade calculator acts as the input for the GPA calculator.

3 Outstanding Features of Grade Calculator

Grade Calculator - FAQs  

What grade do i need to pass a college class  .

The grade needed to pass a college class varies depending on the grading system used by the schools, colleges, and academic institutions . In many cases, a passing grade is a D or higher, which is usually equivalent to a numerical grade of 60% or more. However, some programs or courses may require a higher minimum passing grade, so it's important to check your college's policies.  

How do you calculate the percentage grade?  

To calculate a percentage grade, you divide the points earned by the total points possible and then multiply by 100. For example, if you earned 85 points out of a possible 100, your percentage grade would be: (85/100) * 100 = 85%.  

How much will a 0 affect my grade?  

A zero can significantly impact your grade, especially if it's for a major assignment or test. Since a zero has a large weight in the calculation of your average score, it can pull down your overall grade significantly.  

How much will a 71 affect my grade?  

The impact of a 71 on your grade depends on several factors, such as the weight of the assignment or test in the overall course grade and the grading scale used by your instructor. If the 71 is for a major assignment or test and carries a significant weight in the course, it could have a noticeable effect on your overall grade, potentially lowering it. However, if the assignment is one of many and has a lower weight in the course, its impact may be less significant.

Calculator Instructions

• In the top part of the form, enter how much your final exam is worth and the grade that you would like to get in the class. For example, your final test might be worth 20% of your overall grade and you want to get at least a 93% in the class. You would enter these numbers into the form.
• In the bottom half of the form, enter a description (optional) of the classwork, the grade received for that classwork, and the weight of the classwork. Most class grades are made up of several components such as homework assignments, tests, exams, quizzes, class participation, attendance, etc. For example, a class exam might be worth 10% of your grade and you received a 95% on the test. You would enter those values into the form.
• If you need more than four rows, press the "Add Row" button to add an additional line. You can add as many rows as you need.
• Once you have finished entering your grades, press the "Calculate" button and the grade you need on the final exam will be displayed.

Final Grade Formula

final grade = ((g wanted x w total ) - gw) / w final

w total = w 1 + w 2 + w 3 + ... + w final

w 1 = weight of assignment #1

w final = weight of final exam

gw = g 1 x w 1 + g 2 x w 2 + g 3 x w 3 + ...

g 1 = grade for assignment #1

g wanted = grade wanted in the class

Example Calculation

Let's say your class has the following grading plan.

Now let's assume you received the following grades on your classwork.

Finally, let's assume that you want to get a 90% in the class. To determine what you need to get on your final exam in order to get a 90% in the class, let's do some math using the formula above.

First add the weight of all the class assignments together including your final:

w total = 10% + 10% + 20% + 20% + 20% = 100%

Next, multiple the grade you received on each assignment by the weight of the assignment.

gw = (91% x 10%) + (85% x 10%) + (75% x 20%) + (95% x 20%) + (97% x 20%) = 7100%

Now, calculate what you need on the final exam:

final exam grade = ((90% x 100%) - 7100%) / 20% = 95%

This is how you manually calculate your final grade. Of course, you can make your life a little easier using the calculator above!

What if my class grade is based on points rather than percentages?

Let's assume you have the following class syllabus that is based on points.

Let's assume you received the following grades.

To enter these grades in the calculator above, you first need to calculate your grade percentage for each assignment using the following formula:

grade percentage = points earned / possible points x 100

So taking your mid-term test grade as an example, we get the following:

mid-term test = 190 points earned / 200 possible points x 100 = 95%

In the weight column of the calculator, you would enter the possible points for each assignment.

Assuming you wanted to get at least a 90% in the class and your final exam is worth 250 points (i.e.the weight), you would enter the following information into the calculator.

In this example, you would need to get a 93.6% on your final in order to get a 90% in the class.
