About Vendor Quote Comparison Calculator

Quotes are only comparable once every cost the buyer will incur is loaded onto them. A lower unit price frequently loses on an evaluated basis after freight, duty, tooling amortisation and inspection costs are added, which is why award decisions should use total evaluated cost rather than headline price.

Formulas

Evaluated total

Evaluated total = Quantity x Unit price + Additional evaluated costs

Award rule

Award to the lowest evaluated total cost, not the lowest unit price

Worked example

With the default values below, Vendor Quote Comparison Calculator returns Lowest evaluated total cost of $208,500.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What other costs should be loaded in?

Payment terms value, minimum order quantity effects, qualification and tooling cost, expected rejection rate and any lead-time-driven safety stock.

Should quality and delivery scores be included?

For a full award decision, yes — combine evaluated cost with a weighted scorecard so non-price factors are visible rather than argued informally.
