The hidden costs of underinsurance: What every operator needs to know

It's tempting to cut insurance costs by lowering coverage limits or raising deductibles. But underinsurance carries hidden costs that can far exceed any premium savings.

What is underinsurance?

Underinsurance means your coverage limits are lower than the actual value of your assets or potential liabilities. It happens in a few ways:

• Building undervaluation. Insuring a building for less than its replacement cost.
• Inadequate liability limits. Coverage that won't fully protect against a major claim.
• Missing coverage types. Gaps in protection for specific risks.

What is the coinsurance trap?

Most commercial property policies include a coinsurance clause. It typically requires you to insure your building for at least 80% of its replacement value.

Here's where it gets dangerous. If you're underinsured and file a claim, the penalty isn't just the coverage gap. The coinsurance formula can cut your payout significantly.

A real example

• Building replacement cost: $10 million
• Coverage purchased: $6 million (60% of value)
• Coinsurance requirement: 80%
• Loss amount: $500,000

Expected payout: $500,000 Actual payout: $375,000 (75% of the loss)

You'd owe $125,000 out of pocket. And that's on top of any deductible.

What about liability coverage?

Underinsurance on liability coverage can be even more painful. A single serious injury claim can pass $1 million. If your limits are $500,000, you're personally responsible for the rest.

How do you protect yourself?

1. Get current valuations. Update building values annually using construction cost indices.
2. Review limits regularly. As your portfolio grows, your coverage should too.
3. Work with specialists. General brokers may not understand property-specific risks.
4. Base coverage on actual exposure. Use accurate valuations and risk assessments, not arbitrary limits.

These steps make sure you're actually protected when it matters most.
