GPA Calculator

About the GPA Calculator

Work out your grade point average (GPA). Choose your scale, then list each subject’s grade and credits — one per line — and your GPA updates as you type.

Use letter grades on the US 4.0 scale (A, A-, B+ …) or the Australian 7-point scale (HD, D, C, P, F). You can also type grade points directly, such as 3.7.

How does the GPA Calculator work?

Each grade is converted to grade points and multiplied by the subject’s credits. The total is divided by the total credits, so subjects worth more credits count for more.

GPA Calculator formula

GPA = Σ (grade points × credits) ÷ Σ credits

Example

A (4.0) in a 3-credit course and B+ (3.3) in a 4-credit course: (4.0 × 3 + 3.3 × 4) ÷ 7 = 25.2 ÷ 7 = 3.60.

Frequently asked questions

Is this my official GPA?

It’s a close estimate. Universities set their own rules — for example on failed or repeated subjects — so your transcript is the official figure.

What’s a good GPA?

On the 4.0 scale, 3.0 is a B average and 3.5 or above is strong. On the Australian 7-point scale, 5 is a credit average and 6 or above a distinction average.
