Calculate a simple grade average, a weighted course grade, or the score you need on a future assessment to reach your target.
Choose a calculation mode. Weighted mode accepts any consistent course weighting system.
Polish-style grades such as 4+ and 5- are estimated as ±0.25. Enter a decimal value if your school uses a different conversion.

Enter grades and weights to see the result.
It provides three modes: a simple average, a weighted grade, and a target-grade calculation that estimates the score needed on a future assessment to reach a chosen overall average. This Grade Calculator can also be used as a Weighted Grade Calculator, Final Grade Calculator, and School Grade Calculator. It works for primary schools, high schools, and universities alike.
There are two common methods for calculating grades. You can either calculate manually or use a calculator to get instant and precise results.
Note down all your scores, grades, or percentages received in tests, exams, projects, quizzes, and assignments.
Check the weight of each grade. Tests may count for 30%, quizzes 10%, homework 20%, and the final exam 40%.
Multiply every grade by its assigned weight to determine its contribution to the final result.
Sum all weighted scores together to get the final grade.
Example Calculation:
Homework: 85 × 20% = 17 · Quiz: 90 × 10% = 9 · Test: 80 × 30% = 24 · Final Exam: 88 × 40% = 35.2
Total Weighted Score: 17 + 9 + 24 + 35.2 = 85.2% → Final Grade
The simplest and fastest way to calculate grades is by using our online Grade Calculator. It automatically performs all the calculations.
In the Assignment/Exam field, write the name of your assessment (optional but helps you stay organized).
Enter your grades, scores, or percentages in the Grade field (e.g., 80, 91, 75).
Put the weight assigned to each grade in the Weight field (percentages, points, or credits).
Click "Add Row" if you have multiple tests, exams, or assignments, and repeat for each one.
The Grade Calculator automatically shows your weighted grade average in real time — no Calculate button needed.
A Grade Calculator can use different formulas. The most common are the Point-Based Formula and the Weighted Grade Formula.
Points-Based Formula — used when assignments are scored with points.
Weighted Grade Formula — used when different assignments have different weights.
| Assessment | Points Earned | Points Possible |
|---|---|---|
| Homework | 90 | 100 |
| Quiz | 85 | 100 |
| Test | 120 | 150 |
| Final Exam | 130 | 150 |
| Total | 425 | 500 |
Final Grade: 425 ÷ 500 × 100 = 85%
| Assessment | Grade | Weight | Calculation | Weighted Score |
|---|---|---|---|---|
| Homework | 85 | 20% | 85 × 20% | 17.0 |
| Quiz | 90 | 10% | 90 × 10% | 9.0 |
| Test | 80 | 30% | 80 × 30% | 24.0 |
| Final Exam | 88 | 40% | 88 × 40% | 35.2 |
| Total | — | 100% | — | 85.2 |
Final Grade = 85.2%
Grade Calculator and Weighted Grade Calculator are very similar, but serve slightly different purposes.
| Feature | Grade Calculator | Weighted Avg Calculator |
|---|---|---|
| Main purpose | Academic grade calculation | Any values with weights |
| Application | School, university, GPA | Finance, statistics, grades |
| Weights | Optional (% or points) | Required |
| Output | Final grade as % | Weighted average |
| Assessment | Grade |
|---|---|
| Homework | 85 |
| Quiz | 90 |
| Test | 80 |
| Final Exam | 88 |
Regular Grade Calculator: (85 + 90 + 80 + 88) ÷ 4 = 85.75% — every grade is treated equally.
| Assessment | Grade | Weight |
|---|---|---|
| Homework | 85 | 20% |
| Quiz | 90 | 10% |
| Test | 80 | 30% |
| Final Exam | 88 | 40% |
Weighted Grade Calculator: 85.2% — the final exam with 40% weight influences more than the quiz with 10% weight.
Use a Grade Calculator when all grades have the same value.
Use a Weighted Grade Calculator when tests, quizzes, and exams have different weights.
Most schools and universities use a weighted grading system — the Weighted Grade Calculator often provides a more accurate result.
Keeping accurate track of grades becomes a headache, especially when projects, quizzes, and exams all contribute differently to your final result.
Add estimated scores of upcoming exams and see how different outcomes will affect your final grade.
The calculator clarifies which assessment categories matter most, so you can focus your effort where it counts.
Track grades regularly after every test, quiz, or assignment instead of waiting until the end of the semester.
Manual calculations increase error risk with multiple categories. The Grade Calculator performs everything automatically for greater accuracy.
Get fast results without spreadsheets or complex formulas. Focus on learning, not calculating.
100% free, responsive, works on desktop, tablet, and mobile — no installation or registration needed.

Calculate course averages, semester results, weighted grades, and GPA-related estimates based on credits and weights.
Analyze student results, monitor progress, and help plan more effective study strategies for better outcomes.
Accurate grade calculation is important for students, teachers, and parents. Even a small mistake can lead to an incorrect final result.
One of the most common mistakes is applying the wrong weight to assignments, tests, or exams. If an assessment is worth 40% of the final grade but entered incorrectly, the final result will be wrong. Always verify weights against your school's grading policy.
It's easy to forget a category when calculating grades, especially with multiple assessments. Even one missing grade can significantly change your final result.
Grading scales differ across schools and universities. Using the wrong scale — points, percentages, letter grades, or GPA — will produce incorrect calculations.
Manual calculations are prone to arithmetic errors. Always double-check your calculations or use the Grade Calculator to ensure accuracy.
Many students forget to include extra credit or bonus points. Every point matters to your final grade — always account for any additional points awarded by your teacher.
