How do you calculate a supplier risk score?

Score severity, occurrence, and detection on a common scale, apply the weightings, and sum them. With severity 6, occurrence 4, and detection 3 under the built-in weighting, the example resolves to a score of about 4.55.

What do severity, occurrence, and detection mean here?

Severity is how damaging a supply interruption would be; occurrence is how frequently issues happen; detection is how well procurement controls catch a problem before it bites. Higher inputs mean more risk on each axis.

What is a good supplier risk score?

Lower is better. There is no universal cutoff - rank your suppliers relative to each other on the same scale and set a threshold above which a vendor needs a second source, audit, or buffer. The 4.55 example is a mid-range read.

Why use weighting instead of a simple sum or product?

Weighting lets you emphasize the axis that matters most for educational equipment - often severity, because a single-source glassware outage can halt classes. A weighted blend keeps the score from being dominated by one inflated input.

Can I compare a furniture supplier to a glassware supplier with this?

Yes, as long as you use the identical scoring scale and definitions for both. That consistency is the whole point - it lets you line up dissimilar suppliers on one risk ranking.

How is this different from an FMEA RPN?

A classic RPN multiplies severity, occurrence, and detection; this calculator uses a weighted sum so no single high input automatically dominates. Both aim to rank risk, but the weighted approach gives smoother, more comparable scores.

Educational & Classroom Lab Equipment calculator

Educational Equipment Supplier Risk Score Calculator

A supplier risk score distills three FMEA-style dimensions - how bad an interruption would be, how often issues occur, and how well procurement would detect a problem early - into a single weighted number for ranking suppliers. Sourcing and procurement teams for educational equipment use it to compare vendors of furniture, instruments, safety products, glassware, and kit components on one consistent scale. A higher score flags a supplier that deserves a second source, an audit, or a buffer stock. It turns scattered gut feel about vendor reliability into something you can sort, track, and defend in a sourcing review.

What this calculator does

Score supply risk for classroom lab benches, fume hood components, sinks, faucets, microscopes, electronics trainers, robotics kits, glassware, or specialty school-lab parts.
Use it when educational equipment supplier risk in educational and classroom lab equipment needs a defensible ranking against other educational and classroom lab equipment risks for the next review.
It computes a single weighted risk score by combining severity, occurrence, and detection scores using fixed weightings.

Formula used

Educational equipment supplier risk score = supply interruption severity score × weighting + supplier issue occurrence score × weighting + procurement detection control score × weighting
Use the same scoring scale when comparing suppliers for furniture, instruments, safety products, glassware, and kit components.

Inputs explained

Supply interruption severity score:
Supplier issue occurrence score:
Procurement detection control score:

How to use the result

Use it during supplier selection, annual vendor reviews, or whenever a quality or delivery incident prompts a reassessment.
The score is only as good as the inputs - it relies on consistent, honest scoring across raters and the same scale for every supplier, or comparisons between vendors become meaningless.

Current U.S. benchmarks

Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
