How do you calculate supplier ingredient risk?

Multiply the severity, occurrence, and detection scores together. With severity 6, occurrence 4, and detection 3, the risk priority number is 6 × 4 × 3 = 72, using a consistent scale across all suppliers.

What is a high supplier risk score?

On a 1-10 scale, RPNs above roughly 100-120 usually warrant action, and any single input at 9-10 (a severe or undetectable failure) deserves attention regardless of the product. Keep the same scale across every ingredient to compare fairly.

What do severity, occurrence, and detection mean?

Severity is how harmful a failure would be, such as a contaminant reaching pets. Occurrence is how often the issue is likely. Detection is how hard it is to catch at receiving or QC before it enters production; higher detection scores mean harder to catch.

Why multiply instead of add the three scores?

Multiplying makes a high value in any one dimension dominate the result, which is the point: an undetectable, severe failure should rank far above three middling scores, and addition would flatten that.

Should detection be scored high when it is easy or hard to catch?

In standard FMEA, a high detection score means the failure is hard to detect, which is worse. Score easy-to-catch issues low and hidden ones high, and keep that convention across all suppliers.

How do I use the score to prioritize?

Rank suppliers by RPN and work the top of the list first with audits, incoming testing, or dual sourcing. Re-score after you add a control, since better detection or lower occurrence should visibly drop the number.

Pet Food & Animal Nutrition Manufacturing calculator

Supplier ingredient risk Calculator

Supplier ingredient risk is an FMEA-style risk priority number (RPN) that ranks how dangerous each incoming ingredient supplier is by multiplying severity, occurrence, and detection scores. Sourcing, QA, and food-safety teams in pet food and animal nutrition use it to decide which suppliers get audits, certificates of analysis, incoming testing, or dual sourcing, because you cannot inspect everything and dollars should follow the highest-risk streams. Severity captures how bad a failure would be, occurrence how likely it is, and detection how hard it is to catch before it reaches the mixer. The multiplied score turns three gut feels into a comparable number that focuses limited QC resources where they prevent the most harm.

What this calculator does

Estimate supplier ingredient risk for pet food and animal nutrition manufacturing using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Use it when supplier ingredient risk in pet food and animal nutrition manufacturing needs a defensible ranking against other pet food and animal nutrition manufacturing risks for the next review.
It multiplies severity, occurrence, and detection scores into a single supplier ingredient risk priority number for ranking ingredients and suppliers.

Formula used

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

Inputs explained

Severity of ingredient failure (harm):
Occurrence likelihood of the ingredient issue:
Detection difficulty at receiving and QC:

How to use the result

Use it during supplier approval, annual supplier review, or after an incident to prioritize audits, incoming testing, and dual-sourcing decisions.
RPN is an ordinal ranking, not a probability or dollar figure; the same score can come from very different risk profiles, so always read the three inputs, not just the product.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
The U.S. has 31,130 food manufacturing establishments employing about 1,707,316 workers (Census County Business Patterns, 2023).
