This calculator generates interest rates and interest payments on South African Rand Overnight Index Average- (ZARONIA-) linked financial products for both single and multi-periods. It applies the conventions for loans, money markets, bonds and derivatives as endorsed by the South African Reserve Bank (SARB), while also offering flexibility, as these conventions are not strictly prescriptive.
