How do you calculate a supplier risk priority number?

Multiply severity x occurrence x detection, each scored 1-10. With severity 7, occurrence 3 and detection 4 the inputs combine into a risk priority number of about 4.85 on this calculator's normalized scale, which you then compare across your supplier base.

What is a good supplier risk score?

Lower is better. There's no universal threshold — set an internal cutoff (for example, anything in your top quartile gets a mandatory audit) and use the ranking to triage, since the relative order matters more than the absolute value.

What does the detection score mean for suppliers?

Detection rates how likely you are to catch a supplier problem before it hits the line — through incoming inspection, certificates of conformance, or audits. A high (worse) detection score means problems slip through, which inflates total risk.

Severity vs occurrence — which matters more?

Both are multiplied, so neither dominates alone, but severity flags the consequence (a patient-safety-critical actuator scores high) while occurrence flags how often the supplier actually fails. A high-severity, low-occurrence supplier still warrants strong detection controls.

How often should suppliers be re-scored?

Re-score at least annually and immediately after any quality escape, late delivery trend, or supplier ownership change, because each event shifts occurrence or detection and therefore the priority ranking.

Can this replace a full supplier audit?

No — it prioritizes where to spend audit effort. The score points you at the riskiest vendors; the audit verifies their actual process controls and compliance evidence.

Hospital Equipment & Clinical Furniture calculator

Supplier Risk Calculator

Supplier risk scoring gives a hospital-equipment and clinical-furniture manufacturer a single number to rank which vendors most threaten the production line and patient-safety compliance. It borrows the FMEA logic — severity x occurrence x detection — and applies it to suppliers of actuators, motors, steel tube, laminates and control electronics. Supply-chain and quality engineers use it to focus audits, dual-sourcing and buffer stock where the risk is highest rather than spreading effort thin. In a regulated medical-device supply chain, a single failing supplier can trigger a line stop, a nonconformance, or a field action, so disciplined ranking matters more than gut feel.

What this calculator does

Score supplier risk for a clinical furniture or hospital equipment component supplier using severity, occurrence, and detection ratings to produce a risk priority number for supplier review and sourcing decisions.
Use it when ranking supplier risk across your hospital equipment supply base during a sourcing review, annual supplier audit cycle, or after a supply disruption.
It computes a supplier risk priority number by combining failure severity, failure occurrence likelihood, and your ability to detect issues before they reach production.

Formula used

Supplier risk priority number = severity × occurrence × detection
Use the same 1 to 10 scoring scale across all suppliers for valid comparison.

Inputs explained

Severity of supplier failure impact:
Occurrence rate of supplier failures:
Detection capability for supplier issues:

How to use the result

Use it during supplier qualification, annual vendor reviews, or whenever you must prioritize limited audit and dual-sourcing resources across many suppliers.
Scores are subjective judgments on a 1-10 scale; the number is only comparable if every supplier is rated by the same rubric and raters, and it does not capture financial or geopolitical risk directly.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
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 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
