GPA Calculator

What Is the GPA Calculator?

The GPA Calculator computes your grade point average from a list of courses. Each course contributes a grade point value multiplied by its credit hours; the GPA is the total quality points divided by the total credits. You can calculate on a 4.0 or 5.0 scale, with or without weighting for AP and Honors courses. It is useful for checking a semester GPA, estimating what grades you need to reach a target, and sanity-checking a transcript.

How to Use the GPA Calculator

1. Choose the Scale: 4.0 (standard) or 5.0.
2. Tick “Weighted (AP/Honors +1.0)” only if your school weights advanced courses by a full point.
3. Enter one course per line in the format Grade Credits, for example: A 4. The grade is a letter grade such as A, A-, B+, or C, and the number is the course’s credit hours.
4. Click Process.
5. Read the results table: each course’s grade, credits, and grade points, plus total quality points, total credits, and the final GPA.
6. Use Copy to copy the result, or Download to save it as a text file.

Worked Example

On the 4.0 unweighted scale, enter these four courses:

A 4
B+ 3
A- 4
C 3

The calculator produces:

• A, 4 credits: 4.0 points x 4 = 16.00
• B+, 3 credits: 3.3 points x 3 = 9.90
• A-, 4 credits: 3.7 points x 4 = 14.80
• C, 3 credits: 2.0 points x 3 = 6.00

Total quality points: 46.70. Total credits: 14.0. GPA = 46.70 / 14.0 = 3.34 / 4.0.

Limitations

• The tool uses a fixed grade-point mapping (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, C = 2.0, and so on). Schools differ: some use A- = 3.67, some treat A+ as 4.33, and some do not use plus/minus grades at all. Check your school’s scale before treating the result as official.
• Each run covers one set of courses. The tool does not combine multiple semesters or a prior cumulative GPA; to do that, enter all courses together in one run.
• There is no field for course names, so the results table lists each course by its grade. Keep your own list of which line belongs to which course.
• The weighted option adds a flat +1.0 point per course. If your school weights by a different amount, the result will not match.
• The output is an estimate for planning, not an official transcript value.

Frequently Asked Questions

How is GPA calculated?

Each course’s grade point value is multiplied by its credit hours to give quality points. The GPA is total quality points divided by total credits. For example, 46.70 quality points over 14.0 credits gives a GPA of 3.34.

What is the difference between weighted and unweighted GPA?

Unweighted GPA uses the standard 4.0 scale for every course. Weighted GPA adds a bonus for advanced courses; this tool adds +1.0 point per course when the Weighted box is ticked, so an A in an AP course counts as 5.0 instead of 4.0.

Which grades does the calculator accept?

Standard letter grades with optional plus or minus, such as A, A-, B+, B, B-, C+, C, D, and F, each followed by the credit hours, for example “B+ 3”.
