About RivoCalc
What it is
RivoCalc is a free calculator aggregator, built with Australia in mind. We created these tools because the existing alternatives are often generic, US-centric, or missing local context — the wrong currency, the wrong units, examples that don't reflect how things actually work here.
How it works
Every calculator is free and needs no sign-up. Enter your numbers, get your result. No intrusive ads, no personal data collected, no dark patterns.
How we check our formulas
Every RivoCalc calculator is built on a formula derived from verifiable sources: official technical standards, documentation from public agencies, and specifications published by manufacturers. The sources used for each calculation are listed right on the calculator's page, next to the formula, and every page shows the date it was last updated. When a standard is revised or an error gets reported, the formula is corrected and the date is updated.

Our first category covers construction and renovation calculators — paint, cement, tiling, project costs. New categories are in the works: finance, health, conversions and everyday life.
