About the GPA Calculator

GPA weighs each course's letter grade by how many credit hours it is worth, so a high grade in a 4-credit course counts for more than the same grade in a 1-credit course. This calculator computes your overall GPA from any list of letter grades and their credit hours on the standard 4.0 scale.

How It Works

The calculator converts each letter grade to its standard grade-point value (A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0.0), multiplies each by that course's credit hours to get quality points, sums all the quality points, and divides by the total credit hours to get GPA.

GPA = Σ(Grade Points × Credits) / Σ(Credits), using the standard 4.0 scale.

Worked example

Scenario: Four courses: A (3 credits), B+ (4), C (3) and A− (2).

Quality points: A 4.0 × 3 = 12.0; B+ 3.3 × 4 = 13.2; C 2.0 × 3 = 6.0; A− 3.7 × 2 = 7.4.
Total quality points: 12.0 + 13.2 + 6.0 + 7.4 = 38.6.
Total credits: 3 + 4 + 3 + 2 = 12.
GPA: 38.6 ÷ 12 = 3.22.

Result: A GPA of 3.22 on a 4.0 scale.

Tips and common mistakes

Enter one course per line as grade,credits — for example B+,4.
Lines that can't be read are listed so you can fix them; nothing is silently skipped.
Schools differ on A+ (4.0 or 4.3) and pass/fail courses; check your school's policy.

Assumptions & Limitations

Uses the standard US 4.0 grade point scale (A=4.0 down to F=0.0 with +/- adjustments), though some schools use slightly different scales.
Each line should list a letter grade and credit hours separated by a comma.

Does not account for schools using a 5.0 scale for honors/AP courses, plus/minus grading variations, or pass/fail courses, which some institutions handle differently.

Know your school’s GPA rules

GPA systems are not universal. Schools may use 4.0, 4.3, 5.0, 10-point or percentage-based systems, and weighted courses may receive extra points. Credit hours also affect a weighted GPA. Always compare the result with your institution’s official grading policy.

For a credit-weighted GPA, multiply each course grade point by its credits, add those quality points, then divide by total attempted credits.

Frequently Asked Questions

What grade point scale does this use?

This calculator uses the standard 4.0 scale common at most US colleges and universities, where A=4.0, A-=3.7, B+=3.3, B=3.0, and so on down to F=0.0 — check your specific institution's scale if it differs.

How do I format multiple courses?

Enter one course per line, with the letter grade and credit hours separated by a comma, like 'A,3' for an A grade in a 3-credit course, then add additional lines for each other course.

Does a Pass/Fail course affect GPA?

Most schools exclude Pass/Fail courses entirely from GPA calculation — simply leave those courses out of your list, since including them with an assumed letter grade would distort the result.

Which grade scale is used?

A standard 4.0 scale: A/A+ 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, F 0.

How do I calculate cumulative GPA?

Add every course from all terms, or enter each past term's GPA as a line with its total credits.
