A Weighted Average, Not a Simple Grade Average

Averaging letter grades without accounting for credit hours treats a 1-credit elective the same as a 4-credit core course, which misrepresents how GPA actually works academically. The correct calculation weights each course's contribution by its credit hours, giving heavier courses proportionally more influence on the final number.

Why Specific Grade-Point Values Can Differ Between Schools

While the 4.0 scale is broadly standard, the exact point value assigned to grades like B+ or A- varies somewhat between institutions. Checking your specific school's official grading scale ensures the point values you enter align precisely with how your institution actually calculates GPA.

Cumulative Versus Per-Semester Calculation

Entering courses from multiple semesters together calculates a cumulative GPA across that combined course history, while entering just one semester's courses gives that semester's specific GPA -- the same underlying calculation works for either scope depending on which courses you include.

Frequently Asked Questions

Each course's grade points (on the chosen scale) multiply by its credit hours, these products sum across all courses, then divide by total credit hours -- a weighted average that gives more influence to higher-credit courses, reflecting their greater weight in actual academic standing.

A 4-credit course contributes more to your overall GPA than a 1-credit course with the identical letter grade, since credit hours represent that course's relative weight in your overall academic course load -- ignoring this would treat all courses as equally significant regardless of their actual time and content weight.

Most US institutions use a 4.0 scale, but exact grade-point values for specific letter grades (whether a B+ is 3.3 or 3.5, for example) can vary by institution. Check your specific school's official grading scale for precise alignment.

Yes, enter all courses across every semester you want included in one combined calculation, and the weighted average will reflect your cumulative GPA across that full course history.

This calculator's underlying math (weighted average by credit hours) works the same regardless of scale -- you'd just need to use grade-point values matching your school's specific scale rather than the standard 4.0 values.
