About the Edith Cowan University (ECU) Grade Average Calculator
Edith Cowan University (ECU) grades in percent and maps those marks to 5 letter grades. It publishes no grade-point value for any grade, so there is no official ECU GPA — standing is expressed as a percentage average. This calculator follows ECU's official scheme (Edith Cowan University (ECU), WA, AU Grading System) and reports the same credit-weighted percentage ECU does.
To calculate your average at ECU, enter each course's name, credit hours, and the marks you scored. The calculator weights every course by its credit hours and divides total weighted marks by total credits — no signup required, and your inputs stay in your browser. It deliberately shows no 4.0-scale figure: any such number would come from a third-party conversion table rather than from ECU.
How ECU's grading system works
What does an HD mean at ECU?
An HD is the highest grade awarded at ECU, typically requiring 80% or higher. ECU attaches no grade-point value to it — the percentage band is the whole of what the grade means.
What about a US 4.0 GPA equivalent?
ECU publishes no grade points, so there is no official ECU figure to convert from — and this page will not invent one. Third-party tables that assign a 4.0-scale value to ECU letters are conversions built by other organisations for their own purposes, not ECU's grading system. If you need an equivalence for an application, admissions offices ask for an official transcript evaluation rather than a self-converted figure, and your percentage average is the number ECU itself certifies.
Semester average vs overall average
Your semester average covers one term; your overall average covers every term you've completed, weighted by credit hours. Both are percentages — ECU publishes no grade points, so neither is a GPA.
Track your average across semesters
Save each semester once you've calculated it, and the tracker keeps a running overall average using the standard credit-weighted formula: Σ(average × credits) ÷ Σ(credits). Heavier semesters pull the overall figure harder than lighter ones.
You can save a semester by course — enter every course and click "Save as semester" — or as a quick entry with just the semester average and its credit hours, useful for past terms you don't want to re-type. Both modes feed the same formula. Semesters can be locked, renamed, or deleted at any time.
Your tracker data stays on this device — nothing is sent to our servers, and no signup is required. A persistent "Clear all tracker data" option lets you wipe it whenever you want.
