Why Use This Calculator

Calculating a semester GPA from letter grades and credit hours online for free saves manual math every time a new grade posts. This tool weights each course by its credit hours, giving an accurate cumulative GPA instantly rather than a simple grade average.

How It Works

This credit-hour-weighted-GPA-calculator multiplies each course's grade point value by its credit hours, sums these totals across all courses, then divides by total credit hours to produce a properly weighted GPA. It's a free, instant, local alternative to College Simply's GPA calculator for a quick semester grade check.

Key Features

The letter-grade-to-GPA-converter uses a standard 4.0 scale grade point mapping (A+ and A both count as 4.0, down through F at 0.0), matching the grading convention used at most universities. As a semester-GPA-tool, you can add as many course rows as needed for a full course load, and the calculation updates the moment you click Calculate. Any course can be removed individually with its own remove button, the result now breaks down total credit hours and total quality points alongside your GPA, and a Copy Result button captures the full summary.

Common Use Cases

Students calculate their semester GPA the moment all final grades are posted. Students planning course loads project how a hypothetical grade in an upcoming course would affect their overall GPA. Academic advisors help students understand how credit hours weight differently in the overall calculation, and students applying to graduate programs verify their calculated GPA matches their official transcript. Scholarship applicants verify their exact GPA meets a minimum threshold before submitting an application.

Tips for Best Results

Double-check that your institution uses the standard 4.0 scale grade point values this calculator assumes — some schools use slightly different scales or include plus/minus distinctions differently, which could produce a small discrepancy from your official transcript GPA. Always add every course from the term for an accurate credit-weighted result, since omitting even one low-credit course can shift the calculation.

How is GPA calculated using credit hours and letter grades?

Each course's grade point value is multiplied by its credit hours, these totals are summed, then divided by total credit hours for a weighted average.

What is the standard grade point scale used for GPA calculation?

Most U.S. institutions use a 4.0 scale, where A equals 4.0, B equals 3.0, C equals 2.0, D equals 1.0, and F equals 0.0, with plus/minus variations.

Does this calculator match my official university GPA exactly?

It should closely match if your institution uses a standard 4.0 scale; some schools use slightly different point values for specific grades.

Can I calculate a cumulative GPA across multiple semesters?

Yes, add all courses from every semester you want included as separate rows for a combined cumulative calculation.
