Hazard Ranking Score Calculator

Work out hazard ranking score instantly with clear inputs, formula shown and shareable results.

About Hazard Ranking Score Calculator

The Fine-Kinney method multiplies three independently scored factors: probability that the event occurs given exposure, frequency of exposure, and consequence severity. Because the factors multiply, a rare event with catastrophic consequence and a frequent event with minor consequence can rank similarly, which is the method's purpose.

Formulas

Fine-Kinney score

Risk = probability x exposure x consequence

Bands

Under 20 acceptable, 20-70 attention, 70-200 correction needed, 200-400 immediate, above 400 stop

Worked example

With the default values below, Hazard Ranking Score Calculator returns Hazard ranking score of 270.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Preliminary estimate only. Hazard ranking must be applied by a competent person using the factor tables of the chosen method.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Hazard Ranking Score figure worked out?

Risk = probability x exposure x consequence. The Fine-Kinney method multiplies three independently scored factors: probability that the event occurs given exposure, frequency of exposure, and consequence severity.

How does this differ from a risk matrix?

It separates exposure frequency from probability, which a two-axis matrix conflates. That matters for hazards that are individually unlikely but encountered many times a day.

What values do I need to enter?

This calculator takes 3 inputs: Probability factor, Exposure factor, Consequence factor. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
