About the Supply Chain Risk Calculator
Supply chain risk assessment identifies vulnerabilities in your supply network.
The score reflects exposure to disruptions from supplier concentration, logistics complexity, and inventory levels.
Formula
Risk Score = Supplier Concentration + Logistics Complexity + Inventory Buffer
- RS
- — Risk Score
- SC
- — Supplier Concentration Score
- LC
- — Logistics Complexity Score
- IB
- — Inventory Buffer Score
How to use this calculator
- 1
Enter supplier concentration
Number of suppliers (low number = higher risk).
- 2
Enter logistics complexity
Number of transportation modes and handoffs.
- 3
Enter inventory days
Days of inventory on hand.
Example calculations
Electronics supply chain risk
A company has 2 suppliers, 3 logistics handoffs, and 15 days of inventory.
Concentration = 50 (2 suppliers). Complexity = 30 (3 handoffs). Buffer = 10 (15 days). Risk = 50 + 30 + 10 = 90.
- Risk Score:
- 90
- Risk Level:
- High
- Priority:
- Diversify suppliers
High risk (90) — prioritize supplier diversification.
Interpreting your results
0-30: Low risk — good supply chain resilience.
30-60: Moderate risk — monitor key vulnerabilities.
60-90: High risk — immediate action required.
90+: Critical risk — severe vulnerability.

Common mistakes to avoid
-
✗ Ignoring supplier financial health
Supplier financial stability is a key risk factor.
-
✗ Overlooking geopolitical risk
International suppliers face political and trade risks.
Frequently asked questions
›What is a safe supply chain risk score?
Below 30 is low risk. Monitor scores between 30-60.
›How can I reduce supply chain risk?
Diversify suppliers, build inventory buffers, and reduce logistics complexity.
Glossary
