  abstract = {As South Africa is a water-stressed country, determining how to most efficiently use its already scarce water resource is of utmost importance. This research aims to quantify the difference in the water poverty index when calculated with the additive function compared to the multiplicative function. A case study is performed with the Vaal Triangle region in South Africa, which is a relatively small scale with data at a high assurance level. After calculating the indices for the three towns in the region, it is found that there are only small differences in the obtained values. The multiplicative function consistently produced lower index values, but the final recommendation of the town most in need of an intervention would have remained unchanged. It is concluded that some of the factors that might influence the choice of function include the chosen scale, components and sub-components used, and data sources, amongst others. Future research should focus on refining the existing functions and on developing guidelines for index calculation.},
