Does Anyone Even Know What Coinsurance Is?
It's probably the most important item listed in your commercial property insurance policy, yet for many, it remains an unexplained mystery. I'm talking about the Coinsurance Clause.And if you think this is just technical jargon that doesn't matter, I have a cautionary tale for you.I recently handled a claim where an insured had a 90% coinsurance requirement. Due to a simple oversight in calculating their property's value, they were significantly underinsured. That "little mistake" cost them over $1 million in claim payout.This isn't just an anecdote—it's a critical financial risk lurking in policies across the industry.The Simple Truth About CoinsuranceIn simple terms, when you agree to a coinsurance clause (typically 80\%, 90\%, or 100\%), you are making a guarantee to the insurance company.
➡️ Your Guarantee: You promise to insure the property up to the stated coinsurance percentage of its total replacement value.
The reason the insurer insists on this is to ensure fair premiums. If everyone insured only a fraction of their property's true value, the system would collapse.|
How the Coinsurance Penalty Works
If you fail to live up to that guarantee—if you are underinsured—the insurance company gets to reduce their payment to you proportionally.Here's the crucial part: The extent to which you underinsure is the extent the insurance company gets to reduce their payment to you.
For example, if you have a 100% coinsurance requirement and you underinsure your property by 50%, they only have to pay you 50% of what they ordinarily would have to pay for a covered loss.
Imagine a $2 million loss being instantly cut down to a $1 million payout (minus your deductible) simply because you didn't properly value your assets up front.It's a big deal. And as I've seen throughout my career, most business owners never knew they were underinsured until it was too late to recover fully.If you do only one thing today, please contact your insurance broker and ask these two critical questions:
1. "Do I have a coinsurance clause on my property policy, and what is the percentage?"
2. "Based on my current property valuation, am I properly insured to meet that coinsurance requirement?"
Don't wait for a disaster to find out you've made a million-dollar mistake. Knowledge is the ultimate risk management tool.
