Risk cost, not premium: a better way to think about insurance
Insurance decisions often begin with a quote. They should begin with a clearer question: what does the risk cost?

Many insurance decisions begin with the premium: what did we pay last year, and can someone quote less? The shortcut leaves out the most important number: the cost of the risk itself.
When you understand the probability and potential impact of a loss, you can make a more deliberate choice about what to prevent, what to retain, and what to transfer to an insurer.
What “risk cost” means
Risk cost is the expected financial impact of an uncertain event over time. In its simplest form, it combines how likely a loss is with how large that loss could be. Real decisions use a range of possible outcomes rather than a single neat estimate.
Imagine a piece of equipment worth £40. If it is certain to break during the period you are measuring, the risk cost is £40. If the chance is 10%, the simple expected risk cost is £4. An insurance premium will usually be higher than the portion of risk the insurer takes on because it also supports operating costs, capital, and margin.
Which risks should you transfer?
The goal is not to insure everything or to avoid insurance. It is to match the response to the shape of the risk. A business may be able to absorb frequent, smaller losses from a planned reserve while still needing protection from a severe event that could interrupt operations.
| Risk shape | Response to consider | Reason |
|---|---|---|
| Frequent and manageable | Retain more of the risk or use a higher deductible | Routine losses may be more efficient to fund directly when reserves are adequate. |
| Rare and severe | Transfer an appropriate layer | A low-frequency event can still threaten the continuity of the business. |
| Preventable | Reduce the risk before transferring it | Maintenance, security, training, or better controls may lower both exposure and premium. |
| Poorly understood | Improve the data before deciding | Weak assumptions can lead to unnecessary cover or dangerous gaps. |
Insurance is not a yes-or-no decision. The real choice is which layer of risk the business should carry.
Deductibles, reserves, and the cost of certainty
Raising a deductible normally lowers the premium, but it also increases the losses the business must fund. Looking only at expected savings can hide the added volatility. A few bad years may consume several years of premium savings.
A better question is: does the premium saving exceed the additional claims we expect to retain, while keeping the chance of a reserve shortfall within a level the business accepts?
This is where scenario modelling helps. Instead of presenting a single forecast, it shows a distribution of possible annual outcomes, including the tail cases that matter most.
Why better data changes the answer
Broad averages are useful starting points, but two apparently similar assets can have very different exposures. Construction, location, security, maintenance, occupancy, operating controls, and many other details can change both the frequency and severity of a loss.
A strong assessment breaks those factors apart, tests them against multiple relevant data sources, and rebuilds the result for the specific asset or business. Where the data is uncertain, the uncertainty should remain visible as a range.
- Start broad. Establish an appropriate market or location baseline.
- Add the details. Parameterise the features that materially change the exposure.
- Cross-check. Compare methods and data sources rather than relying on one estimate.
- Model a range. Show likely outcomes and severe tail cases, not false precision.
- Reassess. Update the analysis as assets, reserves, controls, and market prices change.
Common questions
Does a lower premium always mean better value?
No. A lower premium may come with a larger deductible, narrower wording, lower limits, or exclusions that matter to your business. Price should be considered alongside the risk being transferred.
Should a business self-fund every small loss?
Not automatically. The answer depends on liquidity, loss frequency, operational tolerance, and how several risks may combine in the same year.
Why use a range instead of one number?
Risk is uncertain by definition. A range makes the uncertainty explicit and helps decision-makers see both ordinary outcomes and the residual chance of a shortfall.
How often should risk be reassessed?
At least when the business, assets, controls, reserves, or insurance market change materially. Ongoing monitoring can identify when more cover is needed or when capital may be released.
