GPA Calculator

Calculate weighted and unweighted GPA accurately

Calculate semester or cumulative GPA in seconds. Enter each course with its grade and credit hours, and the calculator instantly returns weighted and unweighted GPAs on a 4.0 (or 5.0) scale — exactly what universities, scholarship boards and employers expect to see.

GPA tracking matters for class rank, scholarship eligibility, graduate school applications and job recruiting. Knowing your current and projected GPA lets you prioritize the right courses, target the right grade boundaries, and avoid surprises at the end of the semester.

The calculator supports both letter‑grade and percentage inputs, custom grading scales, and AP/Honors weighting bumps. You can save and reload courses across sessions to track progress over time without uploading any personal data.

Worked example: Semester with a retake and a 10-credit module

A student had four 20-credit modules (marks 62, 57, 71, 48) and one 10-credit skills module (mark 80). Weighting by credits, not by ‘five equal classes’, changed the semester average by more than a point. The 48 was a pass at their institution but pulled the mean; they used the calculator to see the effect before meeting a tutor.

Their university uses a specific degree classification algorithm with exit velocity. This calculator does not replace that. It only does the arithmetic you enter.

Limitations

Grade scales differ (US 4.0, UK percentages, plus/minus letters). Mapping letters to points is a choice you must match to your school.
Retake policies (cap at pass, replace grade, average both) are not encoded unless you model them yourself.
It is not an official transcript.
Rounding rules for classification boundaries vary; do not assume 69.5 is a first.

When not to use GPA Calculator

Do not make leave / stay / scholarship decisions solely on this page. Ask the registry.
If you need official GPA, order a transcript.
Do not enter other students’ marks to ‘rank the cohort’ — that is not what the tool is for and may breach privacy.

Your privacy matters

GPA Calculator is designed to run in your web browser. File and text tools process bytes in memory on your device rather than uploading them to a ToolsGuru converter API. Network requests you still see are the page itself, analytics, and ads — not a copy of your document sitting in our logs. How we process files, and how to check.
