How do you calculate DFARS compliance coverage?

Divide compliant line items by total controlled line items and multiply by 100. With 58 compliant of 62 controlled, that is 58 ÷ 62 × 100 = 93.55% coverage.

What DFARS coverage is acceptable for defense contracts?

Most specialty-metals clauses require 100% compliance, so the practical target is full coverage. At 93.55% against a 100% requirement there is a 6.45 percentage-point gap — meaning four line items still block acceptance.

What does the compliance gap to requirement tell me?

It is your coverage minus the required threshold. A 6.45-point gap here flags that roughly four controlled line items still need compliant sourcing or an approved exception before delivery.

Which line items count as controlled?

Items subject to DFARS specialty-metals or qualifying-country provisions — typically titanium, certain steels, and high-performance alloys flowed down through the clause. Commercial-off-the-shelf and exempted items are excluded from the denominator.

What happens if coverage is below 100%?

Non-compliant line items generally cannot be accepted without an approved deviation or domestic-non-availability determination. The four-item gap in this example would each need a compliant source or a documented exception.

How is this different from supplier lot acceptance?

Lot acceptance measures quality conformance at receiving inspection; DFARS coverage measures regulatory sourcing compliance. A part can pass dimensional inspection yet still fail DFARS if its metal origin is not qualifying.

DFARS Compliance Coverage Calculator

DFARS compliance coverage is the share of your controlled material line items that meet DFARS 252.225-7009 specialty-metals and qualifying-country sourcing rules. Supply chain and contracts teams on defense programs use it to prove that flow-down requirements are satisfied before parts are accepted into a build. Because most DFARS specialty-metal clauses require full compliance, even a single non-conforming line item can jeopardize a deliverable — so this metric is really a defect-finder. Tracking coverage and the gap to the required threshold turns a binary contractual risk into a visible, managed checklist.

What this calculator does

Calculate DFARS-compliant material coverage from compliant line items, total controlled material line items, and the compliance target.
a procurement or compliance lead needs to check DFARS material coverage before releasing a defense shipment or quote
It computes the percentage of controlled material line items that are DFARS-compliant and the gap to your required coverage threshold.

Formula used

DFARS compliance coverage = compliant line items ÷ controlled material line items × 100
Compliance gap to requirement = DFARS compliance coverage - required DFARS coverage

Inputs explained

DFARS-compliant material line items:
Controlled material line items requiring DFARS sourcing:
Required DFARS coverage threshold:

How to use the result

Use it during incoming material review, supplier flow-down audits, and pre-delivery compliance checks on defense contracts.
It measures line-item coverage, not severity — and because most DFARS clauses demand 100%, anything short of full coverage typically blocks acceptance regardless of how high the percentage looks.

Current U.S. benchmarks

Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
