How do you calculate quote margin?

Subtract the required amount (cost) from the available amount (price), then divide by the reference amount. With a price of 125, cost of 100 and reference of 100, the margin is (125 - 100) / 100 = 25%.

What is a good margin on a sterilization quote?

It depends on the model - contract sterilization service work often targets 25-40% gross, while pass-through-heavy pouch converting can run thinner. The 25% in the example is a reasonable floor for a validated sterile barrier job carrying testing overhead.

Should validation cost go in the required amount?

Yes - if a new program requires ISO 11607 seal validation, dose mapping or BI qualification, amortize that cost into the required amount, or the quote will show a margin you never actually earn.

What reference amount should I use?

Using cost as the reference gives markup-on-cost; using price as the reference gives margin-on-price. Be consistent across quotes so a 25% here means the same as a 25% on the next job.

Price minus cost vs margin percent - why divide?

The raw gap (25 in the example) does not scale across jobs of different size. Dividing by a reference turns it into a percentage you can compare against your target and across quotes of any dollar value.

How do I protect margin on EO or gamma jobs?

Load every release-testing and downtime cost into the required amount, add scrap for expected seal rejects, and set a minimum-margin floor below which the quote is escalated rather than sent.

Sterilization & Sterile Barrier Manufacturing calculator

Quote Margin Calculator

The Quote Margin calculator returns the percentage margin on a sterilization or sterile barrier packaging quote by comparing the quoted price against your loaded cost. Estimators, sales engineers and plant managers use it when pricing EO or gamma lot runs, pouch and tray sealing jobs, or validation-heavy new programs where cost is easy to underestimate. Sterile barrier work carries hidden loaded costs - dosimetry, BI testing, aeration time, validation amortization and scrap from seal rejects - so a quick, honest margin check keeps the shop from winning volume that loses money on release testing.

What this calculator does

Estimate quote margin for sterilization and sterile barrier manufacturing using production-ready inputs so teams can measure the gap between available and required amounts.
Use it when quote margin in sterilization and sterile barrier manufacturing needs a clean margin number for a sterilization and sterile barrier manufacturing go / no-go review.
It computes margin as the gap between available (price) and required (cost) amounts, divided by a reference amount, expressed as a percent.

Formula used

Quote margin amount gap = available quote margin amount - required quote margin amount
Quote margin = amount gap ÷ reference quote margin amount

Inputs explained

Available quote margin amount:
Required quote margin amount:
Reference quote margin amount:

How to use the result

Use it at quote time to confirm a sterilization or packaging job clears your target margin before you send the price to the customer.
The result is only as good as the loaded cost you enter - if dosimetry, validation amortization or scrap are missing from the required amount, the margin will look healthier than it is.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
