How do you calculate a supplier network resilience score?

Multiply the three ratings together: severity x occurrence x detection. With severity 6, occurrence 4, and detection 3 the risk score is 72 on a raw 1-1000 RPN scale; rank suppliers highest-first.

What is a good supplier resilience score?

Lower is better. Scores below roughly 100 are usually acceptable to monitor, 100-200 warrant a mitigation plan, and anything above 200 (or any factor rated 8+) should trigger dual-sourcing or reshoring review.

What does the detection score mean here?

It rates how hard it is to see a disruption coming before it hits your line. A supplier with real-time capacity visibility scores low (easy to detect); a tier-3 offshore vendor with no early signals scores high.

Severity vs occurrence — which matters more?

Neither alone. Because they multiply, a catastrophic but rare event (10 x 2) and a minor but constant one (2 x 10) land at the same 20. That is the point: the RPN forces you to weigh both plus detection together.

Why use an FMEA RPN for suppliers instead of a simple risk matrix?

A two-axis matrix ignores whether you can detect the problem early. Adding detection surfaces suppliers that are not only high-impact but also invisible until they fail, which is exactly where monitoring investment pays off.

How often should we re-score suppliers?

Re-score quarterly and after any tariff change, qualification of a second source, or a near-miss. The score should drop as mitigations land — if it does not, the mitigation was not effective.

Reshoring & Tariff Strategy calculator

Supplier Network Resilience Score Calculator

The Supplier Network Resilience Score is an FMEA-style Risk Priority Number (RPN) applied to your supply base, multiplying how bad a supplier failure would be, how likely it is, and how hard it is to catch early. Reshoring and tariff-strategy teams use it to rank single-source parts, tariff-exposed lanes, and long-lead components on one comparable scale. It matters because a scarce dual-sourcing budget has to go where the combined risk is highest, not just where severity feels scary. Scoring every critical supplier the same way turns gut-feel debates into a sortable priority list.

What this calculator does

Estimate supplier network resilience for reshoring and tariff strategy using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Use it when supplier network resilience in reshoring and tariff strategy needs a defensible ranking against other reshoring and tariff strategy risks for the next review.
It multiplies severity, occurrence, and detection ratings (each 1-10) into a single supplier resilience risk priority number.

Formula used

Supplier network resilience risk score = supplier network resilience severity score × supplier network resilience occurrence score × supplier network resilience detection score
Use the same scoring scale across comparable supplier network resilience risks.

Inputs explained

Disruption severity if this supplier fails (1-10):
Likelihood of a supply disruption (1-10):
Difficulty detecting the disruption early (1-10):

How to use the result

Use it when triaging your critical supplier list for dual-sourcing, safety-stock, or reshoring decisions, or when a tariff change forces a lane review.
The 1-10 ratings are subjective, and because the three factors are multiplied a single high score can dominate — always scale rate every supplier the same way and re-score after mitigation.

Current U.S. benchmarks

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.
