The cost-performance ratio is a tool used to balance the cost of an item with its effectiveness. It can help shoppers make purchasing decisions and analyze production trends. There are four possible outcomes, and a four-quadrant chart can be used to plot results. However, other factors may be important, and the ratio can fluctuate for products like computers.
Cost-performance ratio is an equation used to balance the cost of an item with its effectiveness. This process can help shoppers make purchasing decisions by assigning rankings to a variety of items based on a variety of factors. The cost-performance ratio can also be used to analyze production trends. It is also known as the price / performance ratio.
There are essentially four main outcomes possible in determining cost-performance ratio. The most desirable result is that the item is low in cost, yet high in performance. In the middle of the scale are high-performance, high-cost, or low-performance, low-cost products. The least desirable ranking tends to be for a product that is high in cost, but low in performance.
These cost-performance results can be plotted for greater clarity on where each product falls relative to the others. A four-quadrant chart, with high-performing products in the top two sections, low-performing products in the bottom sections, and high and low costs on the left and right sides respectively, tends to be most effective. By plotting a graph of each item, it is possible to both find the most desirable product and analyze trends in quality and price.
While the cost-performance ratio can be a useful tool for finding the best quality for the price, items with high ratios aren’t necessarily the best to buy. Particularly with more complex products, there may be elements outside of basic performance or price that may be more important. For this reason, the cost-performance ratio can be useful in making a decision, but it may not be the only factor considered.
The cost-performance ratio can also be used to analyze changes in production. It can track cost and quality changes for specific products, industries, or even the entire economy. Some products undergo dramatic changes as they develop and are assimilated by the public, while others remain essentially static.
Some products, such as computers, tend to have highly fluctuating cost-performance ratios. For example, early computers were extremely expensive, but had limited processing power. As technology has advanced, computers have become more powerful and increasingly accessible to consumers. Even home computers that were once a significant investment can now be purchased for a fraction of their original cost. Products made from limited resources, such as paper and fossil fuels, tend to have static performance and constantly rising prices.
