A little clarity for everyday money.
RandMath is a free collection of financial calculators designed around South African questions, terminology and currency.
A practical starting point
Use the tools to explore a salary, compare borrowing scenarios or plan savings without creating an account. Every calculator exposes its assumptions. Inputs stay on your device unless you choose Save to account.
How we approach accuracy
Calculation functions are separate from the interface and covered by automated tests. Tax and VAT settings link to official sources and show effective and review dates. Estimates remain subject to the limitations described on each tool.
Our business model
The essential calculators are free. Google AdSense connection code is installed on public pages. Ad display depends on Google approval and configuration. Affiliate placements remain disabled. There are no paid recommendations or subscription fees.
