A cost calculating tool for AUVA has been designed and built using MS-Access database and Visual Basic coding. The tool has been designed to calculate future costs to AUVA, the Economy and the Employer. Inflation and discounting rates have been included and the user may calculate costs over a specified period (e.g. a year, range of years) or the lifetime costs for the cohort of people. Complex rules have been included to calculate each of the costs. The AUVA categories are shown in Table 1.
