Introduction

A weighted grade calculator helps you find your overall grade when some assignments count more than others. In most classes, not every task is worth the same amount. A final exam might be worth 30% of your grade, while a homework assignment might only be worth 5%. This tool does the math for you so you always know where you stand.

Enter your assignments, type in your grades and weights, and click Calculate. You will see your weighted average, your letter grade, and a step-by-step breakdown of how the result was found. You can input grades as percentages, letter grades, or points — whatever your class uses.

This calculator also includes a Final Grade Planning feature. It tells you the score you need on your remaining work to reach a target grade. Use it to set clear goals and stay on track before your next test or project is due. If you already know exactly what you need on a final exam, try our dedicated Final Grade Calculator for a quick answer.

How to Use Our Weighted Grade Calculator

Enter your assignment names, grades, and weights to find your weighted average, letter grade, and a full step-by-step breakdown of your score.

Grade Input Mode: Pick how you want to enter your grades. Choose "Percentage" to type a number from 0 to 100, "Letter" to pick a letter grade like A or B+, or "Points" to type the points you earned.

Weight Format: Choose how your weights are set up. Pick "Percentage" if each assignment is worth a percent of your total grade. Pick "Points" if your class uses a points-based system.

Decimal Precision: Choose how many decimal places you want in your results. Pick 0, 1, or 2.

Assignment Name: Type a name for each assignment, like "Midterm Exam" or "Homework 1." This helps you keep track of each entry.

Grade: Type the grade you got on the assignment. If you set the mode to "Letter," pick your letter grade from the dropdown and the number will fill in for you.

Letter Grade: This shows the letter grade that matches your number. You can also pick a letter grade here, and the number will update to match.

Weight: Type how much the assignment is worth. For example, if a test counts for 20% of your final grade, type 20.

Add Row: Click this button to add a new blank row if you have more assignments to enter.

Target Grade (%): In the Final Grade Planning section, type the grade you want to end up with. For example, type 90 if you want an A-.

Target Letter Grade: Pick the letter grade you are aiming for. The target percentage will update to match.

Weight of Remaining Work: Type the total weight of assignments you have not finished yet. The calculator uses this to tell you what score you need on that remaining work to hit your target.

Press Calculate to see your weighted average, letter grade, a bar chart of each assignment's contribution, and a full written breakdown of the math. Press Reset to clear everything and start over.

What Is a Weighted Grade?

A weighted grade is a way to figure out your overall score in a class when some assignments count more than others. For example, a final exam might be worth 30% of your grade, while homework might only be worth 10%. This means the exam has a bigger effect on your final grade than homework does.

Teachers use weighted grades because not all work is equal. A big project that takes weeks should matter more than a short quiz. The weight tells you how much each piece of work counts toward your total grade. Weights are usually shown as percentages, and in a typical class, all the weights add up to 100%. Many schools also use weighted grades to calculate your GPA, where honors and AP courses may carry extra weight through a weighted GPA system.

How Weighted Grades Are Calculated

To find your weighted grade, you multiply each assignment's score by its weight. Then you add all those results together and divide by the total weight. This gives you your weighted average, which is your overall grade in the class.

Here is a simple example. Say you got 90% on homework (worth 20%) and 80% on a test (worth 80%). You would calculate it like this:

  • Homework: 90 × 20 = 1,800
  • Test: 80 × 80 = 6,400
  • Total: 1,800 + 6,400 = 8,200
  • Weighted average: 8,200 ÷ 100 = 82%

Notice that even though you got a 90 on homework, your overall grade is closer to the test score. That is because the test had a much higher weight. If you want to check a single test or quiz score on its own, our Test Grade Calculator can show you the percentage based on correct answers.

Why Weighted Grades Matter

Knowing how weighted grades work helps you plan ahead. If a big exam is worth half your grade, you know to spend more time studying for it. If you have a low score on something with a small weight, it will not hurt your grade as much. Understanding weights lets you focus your effort where it counts the most.

Weighted grades also play a key role beyond individual classes. Your course grades feed into your cumulative GPA, which colleges and employers look at closely. If you need to figure out where you stand across all your courses, use our Semester Grade Calculator or College GPA Calculator. And if you are preparing for standardized tests alongside your coursework, tools like our SAT Score Calculator or ACT Score Calculator can help you estimate those scores as well. For a simpler grading setup where every assignment counts equally, our basic Grade Calculator is a faster option. You can also use a Percentage Calculator anytime you need to convert between fractions, decimals, and percentages while working through your grades.


Frequently asked questions

What is a weighted grade calculator?

A weighted grade calculator finds your overall class grade when different assignments are worth different amounts. You enter each assignment's grade and its weight, and the tool multiplies, adds, and divides for you to give your weighted average.

What is the difference between weighted and unweighted grades?

With unweighted grades, every assignment counts the same. With weighted grades, some assignments count more than others. For example, a final exam worth 40% affects your grade more than a quiz worth 5%.

What happens if my weights do not add up to 100%?

The calculator still works. It divides by the total weight you entered, so your result shows your average for the work you listed. A yellow notice will appear telling you the weights are incomplete and that the result only covers part of your course grade.

Can I use letter grades instead of percentages?

Yes. Set the Grade Input Mode to "Letter" in the settings. Then pick a letter grade like A, B+, or C- from the dropdown for each assignment. The calculator converts it to a number automatically using a standard grade scale.

How does the points mode work?

In points mode, you enter the points you earned as your grade and the total possible points as the weight. The calculator divides your total earned points by total possible points to find your percentage. This is common in classes that grade by points instead of percentages.

How do I find out what score I need on my final exam?

Use the Final Grade Planning section at the bottom. Enter your target grade, type the weight of the remaining work, and click Compute Goal. The tool will tell you the exact score you need on that remaining work to reach your goal.

What grade scale does this calculator use?

It uses a standard US grade scale: A+ is 97–100%, A is 93–96%, A- is 90–92%, B+ is 87–89%, B is 83–86%, B- is 80–82%, C+ is 77–79%, C is 73–76%, C- is 70–72%, D+ is 67–69%, D is 63–66%, D- is 60–62%, and F is 0–59%. Click View Grade Scale in the settings to see the full table.

Can I add more than 8 assignments?

Yes. Click the Add Row button below the assignment table to add as many rows as you need. There is no limit.

How do I remove an assignment row?

Click the red trash can button on the right side of the row you want to delete. You cannot remove the last remaining row.

What does the bar chart in the results show?

The bar chart shows how much each assignment contributes to your weighted average. A longer bar means that assignment has a bigger impact on your overall grade, based on both its score and its weight.

What does the step-by-step breakdown show?

It shows the exact math behind your result. You can see each assignment's weight multiplied by its grade, the sum of those products, the total weight, and the final division that gives your weighted average. This lets you verify the calculation yourself.

What does decimal precision do?

It controls how many decimal places appear in your results. Choose 0 for whole numbers like 85%, 1 for one decimal like 85.3%, or 2 for two decimals like 85.33%.

Can my weights go over 100%?

The calculator will still give you a result, but a warning will appear showing how much you are over 100%. Double-check your weights because most classes have weights that add up to exactly 100%.

What if I leave some rows blank?

Blank rows are ignored. The calculator only uses rows where you have entered at least a grade or a weight. This means you can leave extra rows empty without affecting your result.

Is this calculator free to use?

Yes. This weighted grade calculator is completely free. There is no sign-up, no download, and no limit on how many times you can use it.
