How do you calculate a comparable production quote value?

Multiply the per-unit cost by the lot quantity to get gross value, then multiply by comparable quote scope and expected production realization. With $18.75/unit on 4,800 units at 100% scope and 96% realization, gross is $90,000 and the comparable value is $86,400.

Why is the comparable value lower than the gross quote?

Because realization below 100% prices in expected yield loss and downtime. Here 96% realization shaves $3,600 off the $90,000 gross, leaving $86,400 as the value you can actually count on.

What does 'quote value at risk in production' mean?

It is the dollar gap between gross and comparable value caused by realization below 100%. In the example that is $3,600 - the portion of the $90,000 quote exposed to scrap, rework, or downtime.

What is comparable quote scope?

The percentage of your required work the quote actually covers. At 100% the vendor is bidding the full job; drop it to 80% and only $72,000 of the $90,000 gross is in-scope, with the rest needing a second source or in-house work.

Is the lowest per-unit price always the best quote?

No. A lower price per unit on partial scope or with a 90% realization history can produce a smaller comparable value than a pricier, full-scope, high-yield supplier. This calculator is what makes that visible.

How do I pick an expected production realization figure?

Use the supplier's historical first-pass yield multiplied by expected uptime for the work center, or your PPAP/qualification data. New or unproven vendors warrant a conservative figure like 90-94%.

Production Quote Comparison Calculator

Production Quote Comparison normalizes competing make-to-order quotes so a buyer or estimator can compare them on equal footing instead of on headline price alone. It takes a vendor's per-unit cost and lot quantity, then discounts that gross value for the share of your scope the quote actually covers and the production realization (first-pass yield and uptime) you expect from that supplier. Job-shop estimators, supply-chain buyers, and contract-manufacturing account managers use it during RFQ bake-offs and re-sourcing decisions. A quote that looks cheapest per part can lose once partial scope and a weak yield history are priced in, which is exactly what this calculator surfaces.

What this calculator does

Compare production quote cost across a production lot scenario.
comparing prototype-to-production pricing, alternate routings, or quote revisions for the same customer part
It computes a comparable production quote value by multiplying gross quote value (price per unit times lot quantity) by the fraction of scope covered and the expected production realization.

Formula used

gross production quote value = production quote cost per unit × production lot quantity
comparable production quote value = gross production quote value × comparable quote scope × expected production realization

Inputs explained

Production quote cost per unit:
Production lot quantity:
Comparable quote scope:
Expected production realization:

How to use the result

Use it when comparing two or more supplier RFQs for the same part, or when a single quote covers only part of your build and you need a like-for-like number.
It assumes scope and realization can be expressed as clean percentages; it does not capture tooling amortization, freight, lead-time penalties, or quality-escape costs unless you fold them into the realization figure.
