Your Calculated Grade
Online Grade Calculator for Students
Keeping track of your grades can become difficult when a course includes homework, quizzes, projects, midterm exams, and final exams with different weights. A Grade Calculator helps you understand how those scores contribute to your overall course grade.
Deblew's Grade Calculator lets you enter assignment grades and weights to calculate a weighted class grade. You can also use the final exam calculator to estimate what score you need to reach a desired overall grade.
Instead of repeatedly calculating weighted averages by hand, you can use the calculator to test different grade scenarios and make academic planning easier.
What Is a Grade Calculator?
A Grade Calculator is an online academic tool that helps students estimate their current or final course grade using assignment scores and grading weights.
For example, if homework contributes 20% of your course grade, quizzes contribute 30%, and exams contribute 50%, each category can have a different impact on your overall grade. A weighted Grade Calculator accounts for those differences when calculating the result.
The tool can also help answer practical questions such as: "What is my current grade?", "What grade do I need on my final exam?", and "How will a future assignment affect my overall grade?"

Weighted Grade Formula
A weighted grade gives different assignments different levels of importance. The general formula for a weighted average is:
Weighted Grade =
Σ(Grade × Weight) ÷ Σ(Weights)
Example of a Weighted Grade
Suppose your course has three assessment categories:
| Assessment | Grade | Weight |
|---|---|---|
| Homework | 80% | 20% |
| Quizzes | 90% | 30% |
| Final Exam | 72% | 50% |
(80 × 20 + 90 × 30 + 72 × 50) ÷ 100 = 78%
In this example, the calculated weighted grade is 78% . Your school's grading scale determines the corresponding letter grade.
How to Calculate the Grade You Need on Your Final Exam
If you know your current grade, desired overall grade, and the percentage of the course represented by the final exam, you can estimate the score needed on the final.
Required Final Grade =
[Desired Grade − (Current Grade × Current Weight)]
÷ Final Exam Weight
For example, if your current grade is 85%, you want a 90% overall grade, and your final exam is worth 30% of the course, the calculator can estimate the final exam score required to reach your target.
Because course policies differ, use the exact grading weights provided by your instructor when entering your information.
