How the IB to Percentage Converter works

How conversion works on this page

The IB Diploma is scored out of 45 points (6 subjects × 7 + up to 3 for Theory of Knowledge / Extended Essay). IB does not publish an official conversion to percentage; this tool uses a transparent linear map: percentage ≈ (points / 45) × 100, labeled educational.

Both directions are available via the mode toggle. Results update live; use Reset to clear.

Country / scale context

The IB Diploma combines six subjects plus Theory of Knowledge and the Extended Essay for a maximum of 45 points. Universities publish their own IB offer conditions (e.g. 38 points with 6,6,6 at HL) rather than a single global percentage.

Important limitation

Credential evaluators (e.g. WES) and individual universities may apply course-by-course evaluation that differs from a single overall percentage mapping. Treat outputs as educational guidance for planning, not as an official evaluation report.

Frequently asked questions

Is this an official conversion from a credential evaluator?

No. It applies documented common conventions and cites them. Official WES / university evaluations can differ.

Can I convert both ways?

Yes — use the mode toggle above the inputs.

Where do the bands / formula come from?

Will a university accept this percentage?

Always check the target institution’s published India / overseas equivalency table. This tool does not replace an admissions decision.
