GPA Calculator

What this tool does

Enter each course as credit hours and a letter grade and this tool works out your weighted grade point average on the common US 4.0 scale. It multiplies each course's credits by its grade points, totals the quality points across every course, and divides by the total credit hours so heavier courses count more than light ones. A full breakdown table shows exactly how each course contributed, which you can copy into your own records or compare against your transcript.

A grade point average condenses every grade you earned in a term into one weighted number, and the weighting matters: a 4-credit course that goes badly hurts more than a 1-credit elective. This calculator applies that weighting automatically so you do not have to do the multiplication and division by hand.

How to use GPA Calculator

1. List every course for the term you want to average, one per line.
2. Write each line as credits,grade — for example 3,A- or 4,B+.
3. Use the letter grades the tool recognises: A+, A, A-, B+, B, B-, C+, C, C-, D and F.
4. Check the GPA result at the top; it updates as soon as you edit the list.
5. Open the course breakdown table to see the quality points each course contributed.
6. Copy the table or export it as CSV if you want to keep a record alongside your transcript.

Tips for better results

• If your school uses a 4.3 scale or includes A+ above 4.0, substitute your own grade point for that course by recording the nearest supported letter and adjusting manually afterwards.
• Leave out pass/fail, audit or withdrawn courses; they usually do not count toward GPA and would skew the average if included.
• Enter credits with decimals (for example 0.5) if your institution awards partial credit hours for a course.
• Recompute each term and keep a running list of all courses if you also want a cumulative GPA across several semesters.

Common use cases

• Checking your projected GPA before final grades are posted, using expected grades for courses still in progress.
• Planning which grade you need in a remaining course to keep your GPA above a scholarship or honours threshold.
• Comparing two possible grade outcomes side by side before deciding whether to retake a class.
• Preparing a quick GPA summary for a graduate school or internship application.

Common mistakes to avoid

• Typing grades with the wrong case or stray spaces, such as "a-" or "A -"; the calculator trims spaces and treats letters case-insensitively, but unsupported symbols will raise an error.
• Forgetting to separate a withdrawn or audited course out of the list, which silently drags the average down.
• Assuming the 4.0 scale here matches every university exactly; some schools give A+ a value above 4.0 or use half-point increments for plus/minus grades.
• Mixing semester and cumulative totals in one list; keep separate lists if you want both a term GPA and a lifetime GPA.
