01 / Planning the purchase
Set a common comparison basis
Choose the currency used for both offers and enter a comparison quantity in kilograms. Each offer can use a price per kilogram or per metric tonne. Convert any foreign-currency price yourself before entering it; this worksheet does not retrieve exchange rates. Keep the material form and buying context consistent across the offers.
02 / Planning the purchase
Enter known costs explicitly
Enter the unit price and the additional known costs for each offer. Additional costs are entered as a total for the comparison quantity, not as a per-kilogram amount. A blank cost is not treated as zero. Use the notes fields to record inclusions, exclusions and questions that still need an answer.
03 / Planning the purchase
Read the comparison
The worksheet shows the material subtotal, the total of entered costs and that total per kilogram. It also shows Offer A minus Offer B for the entered totals. These calculations cover only the amounts you supplied. They do not estimate missing transport, taxes or other costs, and a lower entered total is not an automatic supplier recommendation.

Worked arithmetic example
For 1,000 kg, an illustrative price of 2 per kg plus 100 in additional known costs gives a total of 2,100 in the selected currency, or 2.10 per kg. A price of 2,000 per metric tonne produces the same material subtotal. These numbers are examples only, not current market prices or a Changhong quotation.
05 / Planning the purchase
Save a useful purchasing record
Copy or download the comparison with your notes, then ask the suppliers about unanswered items before making a decision. Entries are processed locally in the page and are not uploaded or saved to our server. Changing any input hides the earlier result until you compare again, helping you avoid using a stale total.
