Calculating Your GPA from Grades and Credits
Overview
A GPA (Grade Point Average) calculator turns your letter or percentage grades into a single number that summarizes your academic performance. It weights each course by its credit hours, so a hard four-credit class counts more than a one-credit elective. This tool computes your GPA instantly in your browser — enter each course's grade and credits and see your average update live, with nothing saved to a server.
How to Use (Step by Step)
- 1
Add each course
Enter the grade and credit hours for every class you're counting.
- 2
Let it weight and total
The tool converts grades to points, weights by credits, and sums them automatically.
- 3
Read your GPA
Your weighted average appears instantly; adjust grades to see how each affects the result.
How It Works
Each letter grade maps to a grade-point value on a scale (commonly A=4.0, B=3.0, and so on). The tool multiplies each course's grade points by its credit hours to get quality points, adds up all quality points, and divides by the total credits. That weighted average is your GPA. All the math runs locally, so your grades stay private on your device.
When to Use This
Checking your semester or cumulative GPA before official transcripts post. Figuring out what grades you need this term to hit a target GPA. Deciding whether to retake a course to raise your average. Confirming you meet a GPA cutoff for a scholarship, program, or honor roll. Comparing a weighted vs. unweighted average. Planning your course load around credit-weighted goals.
Frequently Asked Questions
Unweighted GPA treats every course on the same scale (usually 0–4.0). Weighted GPA gives extra points for harder classes like honors or AP, so it can exceed 4.0. Check which scale your school uses.
Important Notes
Grade scales vary by country and school — some use A=4.0, others use different points or a 10-point or percentage system. Confirm your institution's scale so the result matches your official GPA.
