How to use this tool
Replace the starter values with figures from your own requirement, supplier response, purchasing record or finance assumptions. The calculation runs locally in your browser and structures a comparison; it does not authorize a purchase or choose a supplier for you.
What it does not include
The tool does not verify supplier legitimacy, contract enforceability, taxes, duty classification, technical compliance, accounting treatment, financing approval, future exchange rates, tendering rules or public-sector authority.
Privacy: Values entered into this calculator are not intentionally submitted to this website. Avoid entering confidential supplier or personal information on shared or untrusted devices.
