Good day, If I purchased an item for R500 in 2015, how do I calculate the replacement cost value to replace this equipment in 2018 without considering depreciation (eg. if the equipment was completely burnt, I would have to purchase at current market value)? How can I incorporate the rand/dollar exchange rate as well as Producer Price Index (PPI) to the calculation? Essentially I want the calculation to give me an answer as close as possible to the market value.
