よくある質問
What is a QPI calculator?
A QPI calculator adds up the quality points you earn in each course (grade point × units) and divides by your total units to give you a single Quality Point Index. This tool lets you enter every course you're taking, along with its grade and units, and see your QPI update instantly.
Is this QPI calculator free to use?
Yes. The QPI Calculator is completely free, with no sign-up required. You can add as many courses as you need and recalculate as often as you like.
Can I use this calculator for any university?
The main QPI Calculator uses a standard 4.0-scale formula that works for most institutions using a QPI or GPA-style system. For schools with grading quirks — like Ateneo, ADMU, or COMPSAT — we also offer specialized calculators tailored to those contexts.
How accurate is the QPI calculation?
The math itself — Σ(grade point × units) ÷ Σ(units) — is exact. The one variable is the grade-to-quality-point scale, which can differ slightly between institutions, so always cross-check your final QPI against your school's official grade report.
