Supplier Quote Comparator

Different suppliers quote in different units. One sends per-carton EXW, another per kg DDP, a third by pallet in a different currency. This tool puts them all on the same scale.

Best used for: Multi-supplier RFQs, pack-size normalization, buyer decisions.

Supplier quotes

Add a row per supplier. Fill the unit conversion fields to enable richer comparison.

Supplier A
USD
USD

Enter a price and quantity to see normalized values.

Supplier B
USD
USD

Enter a price and quantity to see normalized values.

When to use this calculator

Multi-supplier RFQs, comparing imported vs domestic options, or any time two suppliers quote the "same" product on different unit bases.

Inputs explained

Quote price and quantity describe what the supplier wrote. Unit basis tells the tool what the quantity is in. The pack-size fields (units/kg/cartons per pallet) are optional but unlock more comparison axes when filled. Freight adds anything not included in the quoted price.

Outputs explained

Each quote is converted into total delivered cost, then divided by total units / kg / cartons / pallets. Where data is missing, that column shows "—". The cheapest comparable option is highlighted on the most data-rich basis available.

Worked example

Supplier A: $24/carton, 12 units per carton, 100 cartons → $0.20 per unit. Supplier B: $18/carton, 8 units per carton → $0.225 per unit. Supplier B's lower headline price is actually 12.5% more expensive per unit.

Common mistakes

  • Comparing carton prices across different pack sizes.
  • Mixing EXW and DDP quotes without adding freight to the EXW one.
  • Comparing across currencies without converting first.
  • Ignoring kg-based pricing for products sold by weight.

What this tool does not do

  • Convert currencies — quote everything in one currency before comparing.
  • Score quality, lead time, payment terms, or supplier reliability.
  • Verify incoterm interpretation between you and the supplier.
  • Store quotes between sessions.

Frequently asked questions

Does the tool convert currencies?

No. Currency labels are text only — convert all amounts to a single currency before comparing. We don't pull live FX, by design.

Why is one row missing 'price per kg'?

We can only compute it when there's enough data to convert the quote into kilograms (e.g. kg per carton). Add the missing field to enable that comparison.

What if suppliers include different things in the price?

Use the freight/extra field to add what the supplier excluded (freight, duties, packaging) so totals are like-for-like.
