How do you calculate a country-of-origin cost risk score?

Rate severity, occurrence, and detection on the same scale, then multiply them. With severity 6, occurrence 4, and detection 3, the model returns a risk score around 4.55 on the normalized scale used here.

What do severity, occurrence, and detection mean here?

Severity is how badly a cost exposure hurts if it lands; occurrence is how often it's likely to happen; detection is how hard it is to see coming. Higher detection scores mean lower visibility, which raises risk.

What is a good country-of-origin risk score?

Lower is better. Because the score is a product of three factors, a single high input drags the whole number up. Set a threshold (for example, flag the top quartile of your scored countries) rather than chasing an absolute target.

Why use RPN instead of a simple probability estimate?

A probability-only view buries low-likelihood, high-impact risks. Multiplying in severity and detection ensures a rare but devastating or invisible exposure ranks high enough to get attention.

How should I set the scoring scale?

Use the same scale, commonly 1 to 10, for every country and every factor. Consistency is what makes the scores comparable; mixing scales destroys the ranking's validity.

What raises detection risk for country-of-origin cost?

Opaque supply chains, multi-tier sub-suppliers you can't see, sudden tariff actions, and currency moves that aren't hedged. The harder a cost shock is to anticipate, the higher the detection score and the higher the overall risk.

Reshoring & Tariff Strategy calculator

Country of Origin Cost Risk Calculator

Country of origin cost risk applies a Risk Priority Number (RPN) approach, borrowed from FMEA, to the cost exposures tied to where a part is made. Instead of asking 'how likely is a tariff or disruption,' it forces you to rate severity, occurrence, and detection on a common scale and multiply them, so a low-likelihood but catastrophic exposure still surfaces. Sourcing strategists and risk managers use it to rank countries when one supplier sits in a region facing new tariffs, currency volatility, or logistics fragility. The strength of the method is comparability: scored consistently, every country risk lands on the same number line, making prioritization defensible rather than gut-feel.

What this calculator does

Estimate country of origin cost risk 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 country of origin cost risk 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 scores into a single country-of-origin cost risk priority number for ranking exposures.

Formula used

Country of origin cost risk score = severity score × 0.40 + occurrence score × 0.35 + detection score × 0.25
Use the same scoring scale across comparable country of origin cost risk risks.

Inputs explained

Country of origin cost risk severity score: Score the impact using the same FMEA, quality, safety, delivery, or business-risk scale used by the team.
Country of origin cost risk occurrence score: Score how often the issue appears using defect history, field data, maintenance records, or supplier performance.
Country of origin cost risk detection score: Score how likely current controls are to catch the issue before shipment, use, or customer impact.

How to use the result

Use it when comparing sourcing countries, building a supplier risk register, or prioritizing which origin exposures to mitigate first.
RPN treats all three factors as equally weighted multipliers, so a high-severity, near-undetectable risk can score the same as a frequent minor one, always review the raw severity score alongside the product.

Current U.S. benchmarks

Importers paid an average effective tariff of 12.4% of customs value in 2025 across the 57 manufacturing import families MFG Calcs tracks (USITC DataWeb), up from 3.3% the year before. Statutory and effective rates by family, with top source countries, are at mfgcalcs.com/tariffs.
Sourcing currencies as of 2026-08-21 (Federal Reserve H.10): 6.721 CNY and 16.8909 MXN per USD. Landed-cost comparisons move with these daily rates.
U.S. iron and steel imports ran $2.2B in Jun 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.
