Procurement decisions often require more than a supplier quotation. Professionals need to understand savings, total cost, supplier performance, inventory economics and the underlying cost structure before making important sourcing decisions.
The Buying Desk procurement calculator toolkit provides simple, practical calculators designed around common procurement and supply chain situations.
Procurement Savings Calculator
The Procurement Savings Calculator helps estimate annual savings from a change in unit price and annual purchase quantity. It can be useful for sourcing projects, negotiations, supplier changes and procurement savings analysis.
Total Cost of Ownership Calculator
Total Cost of Ownership looks beyond the initial purchase price. Logistics, quality-related costs and other costs can significantly affect the economics of a sourcing decision.
Should-Cost Calculator
A should-cost model provides a structured way to estimate what a product or component could reasonably cost based on material, processing, labour, overhead and profit assumptions.
Supplier Evaluation Calculator
Supplier selection should consider more than price. Quality, delivery performance and supplier capability can also influence the overall sourcing decision. A weighted evaluation approach provides a structured comparison.
EOQ Calculator
Economic Order Quantity, or EOQ, is a classic inventory management concept used to balance ordering costs and inventory holding costs. It provides a useful starting point for understanding purchasing and inventory decisions.
