How GPA is actually calculated

Each letter grade maps to a grade point – A is 4.0, B is 3.0 and so on – and each course's points are multiplied by its credit hours to give quality points. Your GPA is total quality points divided by total credit hours. This is why a four-credit course affects your average far more than a one-credit course with the same grade, and why a single poor grade in a heavy course is harder to recover from than several in light ones.

Plus and minus grades

Most universities use a 4.0 scale with plus and minus modifiers: A− is 3.7, B+ is 3.3, B− is 2.7 and so on. Some institutions award 4.3 for an A+ and some cap it at 4.0; this calculator uses the more common 4.0 cap. If yours differs, or if it uses a 5.0 weighted scale for honours and AP courses, check the official handbook – the arithmetic is the same, only the point values change.

Cumulative versus semester GPA

Semester GPA covers one term; cumulative GPA covers everything you have taken. To estimate a new cumulative figure, enter your completed credits as a single row (using the grade closest to your current average) and then add this term's courses. It is an approximation, but it is close enough to know whether you are on track for a threshold like a 3.5 honours cut-off.

Frequently asked questions

How do I calculate my GPA?

Enter each course's letter grade and credit hours. GPA is the sum of (grade points × credits) divided by total credits.

What is a good GPA?

3.0 is generally considered solid, 3.5 and above is strong and often required for honours, and 3.7+ is competitive for graduate admissions. Standards vary by institution and field.

How do I calculate a weighted GPA?

Weighted scales give extra points for honours or AP courses, often on a 5.0 scale. Add the extra point to those courses' values manually if your school uses this system.

Does a higher-credit course affect my GPA more?

Yes. Courses are weighted by credit hours, so a four-credit course carries four times the influence of a one-credit course.

Can I calculate my cumulative GPA?

Yes – add a row representing your previous credits and average grade, then add this semester's courses.

Is this the same scale my university uses?

It uses the most common US 4.0 scale with plus/minus grades. Check your institution's handbook if it uses different point values.
