GPA Calculator

Your GPA follows you from your first transcript to graduate-school applications and your first job. Enter your courses, credit hours, and letter grades below to see your GPA on the 4.0 scale — the same weighted-average math your registrar uses.

What is GPA?

GPA stands for Grade Point Average. It is a single number — usually between 0.0 and 4.0 — that summarises every grade on your transcript, weighted by how many credit hours each course is worth.

The system exists so universities can compare students fairly even when they take very different classes. A higher GPA signals a stronger overall record.

In the US, the standard scale runs A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus and minus grades adjust by 0.3 or 0.7 — so an A- is 3.7 and a B+ is 3.3.

Your GPA shows up on every transcript. Graduate schools, scholarship boards, and most employers look at it. Many internships set a minimum GPA before they will read the rest of your application — which is why it pays to know yours at any moment.

How GPA is calculated

GPA uses one weighted-average formula. Credit hours act as weights, so a 4-credit class affects your GPA more than a 1-credit class with the same grade.

• Convert each letter grade to its point value (A = 4.0, B = 3.0, and so on).
• Multiply the grade points by the course's credit hours — that gives the quality points for that course.
• Add the quality points across every course, then divide by total credit hours.

How to use this calculator

The math happens automatically. Four steps:

1. 1
   Add a row for each course

   Type the course name or leave it blank — only credit hours and grade are required.

2. 2
   Enter the credit hours

   Usually 1, 2, 3, or 4. The value is at the top of your syllabus or on your transcript.

3. 3
   Choose the letter grade

   Pick from the dropdown — the calculator converts it to a point value automatically.

4. 4
   Read your live GPA

   The result updates the moment any input changes. No submit button needed.

Why use this calculator instead of doing it by hand

Working out a GPA by hand is not difficult, but it is easy to make small mistakes — multiplying by the wrong credit value, confusing A- with 4.0 instead of 3.7, forgetting a course. Each slip can shift the final number by a tenth or two.

Reasons students reach for this tool: it uses the same weighted-average formula your registrar uses (the result matches your transcript within rounding); every input updates the GPA live; nothing is stored or sent to a server (the calculation runs entirely in your browser); and you can add hypothetical future courses to see exactly how a planned grade would change your GPA.

For most students it is a 30-second job — and worth doing properly when the result feeds into scholarship eligibility, dean's list standing, or graduate-school cut-offs.

Tips to improve your GPA

• Prioritise high-credit courses. A 4-credit A counts four times more than a 1-credit A — put your best effort into the heaviest classes on your schedule.
• Use office hours early. Most grade trouble starts around week three, not finals week. A short conversation with your professor in week four prevents the panic email in week fourteen.
• Retake low grades if your school offers grade replacement. Replacing a D with a B can move your GPA more than an entire new semester of courses, especially in a high-credit class.
• Watch the weighted average. Lighter elective semesters look attractive but barely move the needle — one demanding semester with strong grades shifts your GPA more than three light ones.
• Recalculate after every term so you always know where you stand against your scholarship, honours, or graduate-school target.
