Grade Calculator for High School & College | 100% Free

Imagine this: it’s the end of the semester, and you’re staring at your grade report. You want to know your GPA before it officially posts — or maybe you’re planning which courses to take next to maintain a target GPA. Instead of calculating by hand, a Grade Calculator lets you quickly input your grades and credits, giving an accurate GPA instantly. Whether you’re in high school, college, or university, this free tool removes the guesswork and ensures you know exactly where you stand academically.

Why a Grade Calculator is Important

Calculating your GPA manually can be tricky: courses have different credit values, letter grades convert to numeric points differently depending on your institution, and small mistakes can throw off your calculations. A GPA calculator helps you:

• Save time: Input grades and credits once to get your overall GPA.
  
• Plan courses: Know how future grades will affect your GPA.
  
• Set goals: Determine the minimum grade needed in upcoming courses to reach your target.
  
• Avoid mistakes: Ensures accurate calculations for scholarship eligibility, honors, or graduation requirements.
  

What You Need to Input

The calculator is simple and intuitive. Here’s what it asks for:

• Course Name: Optional, helps you track which course each grade corresponds to.
  
• Grade: Enter your letter grade (A, B+, C, etc.) or numeric equivalent, depending on your school system.
  
• Credit: Enter the credit hours or weight of each course.
  

Once all courses are entered, click “Calculate GPA” to see your result instantly.

How the GPA is Calculated

Most schools use a weighted GPA system, where each grade is converted to a numeric point, then multiplied by the course credit. Here’s the general formula:

Step 1: Convert Grades to Grade Points
For example, in a standard 4.0 scale:

• A = 4.0
  
• A− = 3.7
  
• B+ = 3.3
  
• B = 3.0
  
• C+ = 2.3
  
• C = 2.0
  
• D = 1.0
  
• F = 0.0
  

Step 2: Multiply Each Grade by Its Credit
For example, if you got an A (4.0) in a 3-credit course:
4.0 × 3 = 12.0

Step 3: Sum All Weighted Points
Add all grade × credit values across your courses.

Step 4: Divide by Total Credits
GPA = Total Weighted Points ÷ Total Credits

Example:

• 
  Total weighted points = 12 + 13.2 + 11.1 = 36.3
  
• Total credits = 3 + 4 + 3 = 10
  
• GPA = 36.3 ÷ 10 = 3.63
  

How the Calculator Works

1. Enter the course names (optional, for tracking).
   
2. Select or enter your grade for each course.
   
3. Enter the number of credits for each course.
   
4. Click “Calculate GPA”.
   
5. The calculator multiplies grades by credits, sums them, divides by total credits, and displays your GPA.
   

This process ensures weighted accuracy, making it perfect for high school, college, and even university-level calculations.
