Common questions
Is this hard savings or cost avoidance?
Hard savings — a reduction from a price you actually paid. Avoiding a proposed increase is cost avoidance.
Should freight be included?
Yes if it changes; compare landed prices. Check the formula, example, and limitations on this page before using the result for a real procurement decision.
Multi-year?
Use the contract savings calculator. Check the formula, example, and limitations on this page before using the result for a real procurement decision.
How do I use the Supplier Savings Calculator?

The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Supplier Savings Calculator use?
Annual savings = (current price − new price) × annual quantity. First-year net = annual savings − switching cost. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.
Can the Supplier Savings Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
