About HowMuchExactly

HowMuchExactly turns Australian Medicare data into clear, personalised out-of-pocket cost estimates. The data is publicly available; the calculators make it useful for the people paying the bills.

Why this exists

Out-of-pocket costs in Australian healthcare are highly variable and largely opaque before the bill arrives. People routinely make care decisions without a meaningful sense of what they will pay. HowMuchExactly aims to fix that — one focused calculator at a time, starting with maternity.

How the numbers work

Estimates are based on the Medicare Benefits Schedule (MBS) — the official Australian schedule of fees that determines Medicare rebates — together with the Extended Medicare Safety Net (EMSN) rules where they apply. You enter what your provider is charging; the calculator shows what you're likely to pay out of pocket.

Each calculator's scope is published on its page, including which item categories are covered, what's deferred to later versions, and any in-hospital or derived-fee items the formula doesn't model.

What this is not

HowMuchExactly is an estimation tool based on public data. It is not financial, medical, or legal advice. Actual bills may differ from estimates, particularly where bulk-billing, hospital fees, anaesthesia, or private health insurance arrangements apply outside the calculator's scope.
