Insurance to value

Carrying a property limit that matches the full value of what you insure, so a loss is paid in full and no coinsurance penalty applies.

Also called: ITV, insured to value, adequate limits, insurance-to-value ratio

Insurance to value (ITV) means your limit is close to the real cost of replacing the property. It is expressed as a ratio, limit divided by value. A building worth $1,500,000 insured for $1,200,000 is insured to 80% of value.

Underinsurance has a price. With an 80% coinsurance clause, a $1,500,000 building requires a $1,200,000 limit. If the owner carries only $900,000, the insurer pays 75% of any loss ($900,000 ÷ $1,200,000). On a $200,000 loss the payment is $150,000, less the deductible, and the owner absorbs $50,000 plus the deductible even though the loss was well under the limit (a hypothetical). Some policies with an agreed value waive the penalty after the insurer accepts a signed statement of values.

Costs drift upward, so a limit that was right at purchase can fall behind. The Turner Building Cost Index annual averages rose 8.0%, 6.0%, 3.9% and 4.1% from 2022 through 2025, which compounds to roughly 24%. Update the valuation yearly, use a current replacement cost estimate rather than the purchase price or tax assessment, and include the cost of demolition, code upgrades and soft costs. Many carriers run valuation software at renewal, and you can challenge the number. The guide on insurance to value: setting the right building limit shows how, and the coinsurance penalty calculator tests your limit.
