Instrument Return on Investment Calculator
When buying an instrument, it is crucial to calculate its ROI (Return on Investment) to determine its future profitability. The ROI period should take into account the instrument's lifetime as well as maintenance costs. For instance, if maintenance costs are high, the ROI period may be longer. Considering these factors while calculating the ROI period is an essential criterion in the selection of instruments.
However, focusing only on the ROI period can also be problematic. When purchasing an instrument, there are other factors to consider such as post-purchase support structure, application quality, future scalability, and instrument size. If you only focus on the ROI period, you may overlook these important factors. Therefore, when calculating the ROI period, it is crucial to consider it from a comprehensive perspective.
