How do you calculate a supplier scorecard risk score?

Multiply severity by 0.40, occurrence by 0.35, and detection by 0.25, then add them. With severity 8, occurrence 6, and detection 7 you get 3.2 + 2.1 + 1.75 = 7.05.

What is a good supplier risk score?

On this 1-10 weighted scale, below 3 is low risk, 3-6 is moderate, and above 6 warrants action. A score of 7.05 signals a high-risk supplier that needs a containment or corrective-action plan.

How is this different from a standard FMEA RPN?

A traditional RPN multiplies severity x occurrence x detection (max 1000) and treats all three equally. This weighted version keeps the score on a 1-10 scale and puts extra emphasis on severity, so a dangerous defect isn't masked by good detection.

Why is severity weighted highest at 40%?

Because the consequence of a failure — safety recalls, line-down events, customer escapes — usually costs far more than how often it happens or whether QC catches it. Weighting severity at 0.40 keeps that priority explicit.

Can I compare two suppliers with this score?

Yes, as long as both are scored against the same written rating criteria. A supplier at 7.05 is meaningfully riskier than one at 4.2, which helps justify dual-sourcing or audit frequency.

Should I re-score suppliers over time?

Yes — occurrence and detection change as suppliers improve their process controls. Re-score after each corrective action or at your annual business review to see whether the score is trending down.

Supply Chain & Procurement calculator

Supplier Scorecard Calculator

A supplier scorecard translates the classic FMEA severity-occurrence-detection triad into a single weighted risk score you can use to rank vendors on a common scale. Procurement managers, SQEs, and commodity buyers use it to decide who gets more audits, tighter incoming inspection, or a place on the approved vendor list. Unlike a raw RPN, the weighted version lets you emphasize severity — a catastrophic field failure usually matters more than a merely frequent one. The result gives sourcing teams a defensible, repeatable number instead of gut feel when consolidating spend or qualifying a second source.

What this calculator does

Score supplier performance from quality, delivery, and responsiveness factors.
Use it when supplier scorecard in supply chain and procurement needs a defensible ranking against other supply chain and procurement risks for the next review.
It computes a single weighted supplier risk score by blending severity, occurrence, and detection ratings using fixed 40/35/25 weights.

Formula used

Weighted score = severity × 0.40 + occurrence × 0.35 + detection × 0.25

Inputs explained

Severity of supplier defect impact (1-10):
Occurrence likelihood of supplier failure (1-10):
Detection difficulty before shipment (1-10):

How to use the result

Use it during supplier qualification, annual vendor reviews, or when triaging which suppliers need corrective-action plans or extra source inspection.
The 1-10 ratings are subjective judgments — two engineers can score the same supplier differently, so anchor each scale with written criteria before comparing vendors.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
Sourcing currencies as of 2026-07-02 (Federal Reserve H.10): 6.7886 CNY and 17.4524 MXN per USD. Landed-cost comparisons move with these daily rates.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
