What is the Cost Ratio Method in Vendor Rating?

The cost ratio method in vendor rating involves assessing the total cost of a purchase, inclusive of the selling price and the buyer’s internal operating costs tied to quality, delivery, and service aspects.

These internal operating costs are converted into cost ratios, representing the percentage of the total purchase value. The cumulative cost ratio is then used to adjust the supplier’s quoted unit price, resulting in the net adjusted cost. In this method, the supplier with the lowest net adjusted cost is regarded as the most preferable supplier.
