Assignment Grade Calculator: Grade Multi-Part Assignments
An assignment with multiple parts, an essay graded on intro, body, and conclusion, a lab report scored across procedure, data, and analysis, and a project with separate rubric criteria, needs more than a simple percentage calculator. You need to track each section’s score and combine them into a final grade.
This calculator does that. Enter each question or section as a row with its points earned and possible, or its weight and score. The calculator combines everything and gives you the overall grade for the assignment.
What This Calculator Does
This is for grading ONE assignment that has multiple parts. Each part is scored separately, either as a percentage (e.g., 8 out of 10) or as a weighted section (e.g., “this part is worth 30%, and you got 85%”), and the calculator figures out the total grade.
It is not for tracking multiple assignments across a semester. That is what the grade calculator does. It is not for a simple test where you enter how many you got right or wrong. That is what the test grade calculator does.
This is specifically for when you have an assignment with sections or questions that are scored individually, and you need to combine those individual scores into one overall grade.
Examples: an essay graded by section, a lab report scored across multiple criteria, a project with a detailed rubric, a homework assignment with multiple problems worth different amounts of points.
Points Mode vs. Percent Mode
The calculator has two modes because assignments can be graded two different ways.
Points mode is for when each question or section is worth a certain number of points. You enter how many points were earned and how many were possible for each part. The calculator adds up all the earned points, adds up all the possible points, and divides to get your percentage.
Example:
- Question 1: 8 / 10 points
- Question 2: 15 / 20 points
- Question 3: 27 / 30 points
- Total: 8+15+27 / 10+20+30 = 50 / 60 = 83.33%
Percent mode is for when each section has a weight like a percentage of the total assignment and a score. You enter the weight and score for each section, and the calculator computes a weighted average.
Example:
- Introduction 20% weight: 90% score
- Body 50% weight: 85% score
- Conclusion 30% weight: 88% score
- Weighted average: 20×90 + 50×85 + 30×88 / 20+50+30 = 86.9%
Use whichever mode matches the assignment’s grading. If the rubric lists points per section, use points mode. If it lists percentage weights, use percent mode.
Common Use Cases
Essays graded by section: Introduction, body paragraphs, conclusion, grammar, each scored separately. Enter each section with its points or weight, and get the total essay grade.
Lab reports: Procedure, data collection, analysis, and discussion each have their own score. The calculator combines them into your lab grade.
Projects with rubrics: Creativity 20%, technical execution 40%, presentation 30%, documentation 10%. Each category gets a score. The calculator figures out your overall project grade.
Multi-problem homework: Ten problems, each worth different points. Instead of manually adding up earned points and possible points, enter each problem as a row and let the calculator do the math.
Teacher use: You are grading an assignment with multiple sections. Enter the points or percentages for each section as you grade, and the calculator shows the student’s overall grade immediately.
Student use: You got an assignment back with section-by-section feedback. You want to verify the total grade or understand how the sections are combined. Enter the scores exactly as written on your assignment.
This works for any assignment structure where different parts contribute to a total.
When to Use This vs. Other Calculators
Use this assignment grade when:
- You are grading or checking ONE assignment with multiple parts
- Each part has its own score points or percentage
- You need to combine them into one overall grade
Use the test grade calculator when:
- You have a single overall score for a test
- You are entering “wrong/correct” or total points, not a section-by-section breakdown
- The test is not divided into separately graded sections
Use the grade calculator when:
- You are tracking MANY assignments across a semester
- You want to see your running grade in a course
- You need “what if” scenarios or category tracking
The line: test grade = single score, no breakdown. Assignment grade = multiple parts within ONE assignment. Grade calculator = MANY assignments over time.
If you are looking at a rubric with multiple sections and thinking “I need to add these up,” you’re in the right place.
The Assignment Name Field
At the top of the calculator, there’s an optional “Assignment Name” field. This is purely cosmetic, a label so you can keep track of what you’re calculating.
If you are a teacher grading multiple assignments, you might label one “Essay 1” and another “Lab Report 3” so you do not mix them up.
If you are a student checking your work, you might label it “Midterm Project” or “Chapter 5 Homework.”
The calculator does not use this field in any calculation. It is just there for organization if you want it.
FAQ: Assignment Grade Calculator
What is the difference between this and the test grade calculator?
The test grade calculator is for tests with a single overall score. You enter how many questions you got right/wrong or your total points. This calculator is for assignments with multiple parts that are scored separately. Use test grade for “I got 42 out of 50 on the test.” Use this for “Section A was 24/30, Section B was 18/20, Section C was 90%.”
Can I use this for an entire course grade?
No. This is for ONE assignment. If you want to track all your assignments, quizzes, and exams across a semester, use the grade calculator. That tool handles categories, weights, and what-if scenarios for a full course.
Should I use points mode or percent mode?
Use whichever matches your rubric. If each section lists points like “Introduction: 20 points”, use points mode. If sections list weights like “Introduction: 20% of grade”, use percent mode. Both modes give you the same final percentage if the proportions match.
How many parts can I add?
There is no hard limit. Click “Add row” to create as many rows as your assignment has sections. Most assignments have 3-10 parts, but if yours has more, the calculator handles it.
What if some sections are graded differently from others?
That is fine. In percent mode, each section can have its own weight. In points mode, each section can have different possible points. The calculator automatically accounts for the differences.
Does this calculator save my data?
No. The calculator runs entirely in your browser. Nothing is stored unless you click a share button. If you refresh the page, your data is lost. Use the “Copy link” button to save your calculation as a shareable URL.

Multi-part assignments, essays with sections, labs with criteria, projects with rubrics, need more than “add it up and divide.” Each part contributes differently, and the math gets tedious fast.
This calculator handles it. Enter each section’s score, and you get the overall assignment grade. Whether you are a teacher grading or a student checking, the calculator does the combining for you.
