Introduction: Your Time is Valuable

Finals are over. The last thing you want to do is sit down with a pile of transcripts, credit hours, and complex conversion formulas.

You just want one number: What is your GPA?

You need a tool that handles the mess for you. That's exactly what our Ultimate GPA Calculator does.

Quick Guide: Which Algorithm Should You Choose?

Our calculator supports multiple modes. If you're unsure which one fits your school, check this guide:

1. Standard 4.0 Scale (Unweighted)

Best for: Most High School & College Students

This is the universal standard. It treats all classes equally, regardless of difficulty.

A=4.0
B=3.0
C=2.0
D=1.0
F=0.0

Simple. Direct. No bonus points.

2. Weighted 5.0 Scale

Best for: Students taking AP, IB, or Honors classes

Schools reward you for taking harder classes by giving them "bonus points".

  • AP / IB Classes: An 'A' counts as 5.0 (Scale max is 5.0).
  • Honors Classes: An 'A' usually counts as 4.5.

Tip: If your transcript says "Weighted GPA", use this mode. It's how some students get above a 4.0!

3. Percentage (%)

Best for: Numeric transcripts (0-100)

Only have numbers like "92" or "85"? No problem. We have a built-in conversion table that automatically maps your percentage to the correct GPA point value (e.g., 93-100 → 4.0).

Why Use Our Calculator?

Doing this by hand is prone to errors. The biggest mistake students make? Forgetting Credit Weight.

The "Credit" Trap

A 4-credit Calculus class affects your GPA 4x more than a 1-credit PE class. Simple averaging (adding grades / number of classes) yields the wrong answer. Our calculator handles this Math automatically.

How to Use (3 Steps)

  1. Add Classes: Enter name (optional) and Credits (usually 1, 3, or 4).
  2. Enter Grades: Select Letter Grade or type a Percentage.
  3. Select Type: If it's AP/Honors, toggle the "Weighted" switch (if available).
