What is the 80 percent rule?

You read a policy. You see a rule about 80 percent. That rule tells you how much of your home you must insure to avoid a penalty after a loss. Insurers use the rule to decide how much they pay when you file a claim. The rule links your insurance amount to the value to replace your home.

Why the 80 percent rule matters to you in Florida

You live in Florida. You see hurricanes, strong winds, and heavy rain. Those events can damage roofs, walls, and floors. You want your home fixed quickly and correctly. You also want money from the insurance company that pays the work. The 80 percent rule affects the money you get. It can make a big difference after a big loss.

The simple idea behind coinsurance

Insurance uses a coinsurance rule. The rule asks you to insure a certain percent of your home value. The common percent is 80 percent. You buy insurance that covers at least 80 percent of the cost to rebuild your home. If you do, the insurer pays the full covered loss minus your deductible. If you do not, the insurer reduces the payment.

How the 80 percent rule works step by step

You find your replacement cost. The replacement cost equals the cost to rebuild your home with similar materials. You multiply that cost by 80 percent. The result gives you the minimum insurance the policy wants. The insurer looks at how much insurance you bought. The insurer compares your insurance to the required insurance. The insurer uses a formula to reduce the claim if you carry less than 80 percent.

The coinsurance formula in plain words

You carry the insurance amount. The insurer requires the 80 percent amount. The insurer calculates the ratio of your insurance to the required insurance. The insurer multiplies that ratio by the loss amount. The insurer subtracts the deductible from that result. That final number is what the insurer pays.

You can write the idea like this:

Insurer pays = (Insurance you carried / Insurance required) × Loss − Deductible

Keep the amounts simple. You can use the formula for math. You can also ask a public adjuster to check the math.

A clear example you can follow

You hire a builder to estimate rebuild cost. The builder says $200,000. The policy uses replacement cost. The required insurance equals 80 percent of $200,000. That amount equals $160,000. You buy $120,000 of insurance. A storm causes $50,000 of damage.

Step 1: Insurance required = $200,000 × 80% = $160,000.
Step 2: Ratio = $120,000 / $160,000 = 0.75.
Step 3: Insurer pays = 0.75 × $50,000 − $1,000 deductible = $37,500 − $1,000 = $36,500.

You see that the insurer paid less than the $50,000 loss. The coinsurance reduced the payment.

A small table to show three simple cases

Replacement cost	80% required	Insurance carried	Loss	Deductible	Insurer pays
$200,000	$160,000	$160,000	$50,000	$1,000	$50,000 − $1,000 = $49,000
$200,000	$160,000	$120,000	$50,000	$1,000	(120k/160k)×50k − 1k = $36,500
$200,000	$160,000	$200,000	$50,000	$1,000	$50,000 − $1,000 = $49,000

You can see the pattern. When you carry less than the required amount, the insurer reduces the payout.

Why insurers use the 80 percent rule

Insurers need balance. They pay claims. They also set premiums. The rule prevents very low premiums for high-value homes. The rule pushes you to buy enough coverage. That practice helps keep premiums fair for other policyholders. The rule also helps the insurer avoid paying full losses when the owner underinsures property.

Common mistakes homeowners make

You buy a policy years ago. You do not update the coverage. Construction costs rise. Your policy stays the same. You become underinsured without knowing it. You think your policy covers the home fully. You do not check replacement cost. You assume market value equals rebuild cost. You assume your mortgage requires enough insurance. You skip a professional estimate.

You can avoid these mistakes by checking the rebuild cost often. You can ask a licensed appraiser or a public adjuster to inspect the home. You can update the coverage when construction costs change.

How inflation and construction costs affect the rule

You watch prices go up. Builders raise their rates. Materials cost more. Those price changes raise the replacement cost. The required 80 percent number increases with replacement cost. If you do not increase the insured amount, you fall short. The insurer may then apply a coinsurance penalty when you file a claim.

Replacement cost vs. actual cash value

You may see two phrases: replacement cost and actual cash value. Replacement cost pays to rebuild without subtracting for age or wear. Actual cash value pays replacement cost minus depreciation. You want replacement cost for your dwelling. Many policies offer replacement cost for the house and actual cash value for some items. Read your policy. Ask questions when you do not understand.

How endorsements and coverages can affect the rule

You can add endorsements to the policy. Some endorsements change how the insurer pays. For example, a guaranteed replacement cost endorsement may pay the full cost even if you are underinsured. Other endorsements raise the coverage limit or pay building code upgrades. These endorsements cost more but they can reduce risk of a coinsurance penalty.

Example: roof damage and the 80 percent rule

A hurricane wrecks the roof. You need to replace the roof and repair water damage. The contractor gives an estimate. The cost to rebuild parts of the home rises. Your insurer reviews your policy. The insurer checks whether you carried enough coverage for the whole home. If you carried enough coverage, the insurer pays the covered loss minus the deductible. If you did not, the insurer reduces the payment based on the coinsurance formula.

You should know that roof-only damage sometimes gets handled differently. Some policies have a separate limit for roof repairs or apply separate rules for wind losses. You should read the policy and talk to a public adjuster.

How a public adjuster can help you

You have a claim. You may not know the right steps. A public adjuster works for you. The adjuster documents the damage. The adjuster prepares a claim packet. The adjuster meets with the insurance company’s adjuster. The adjuster explains the rebuild cost and the need to meet the 80 percent rule. The adjuster negotiates on your behalf. The adjuster aims to increase the insurer’s payment when the insurance company underpays.

How to calculate if you meet the 80 percent rule

You find the replacement cost estimate. You multiply that number by 0.8. You compare your policy limit to that number.

If your policy limit equals or exceeds the 80 percent number, you meet the rule.
If your policy limit is lower, you do not meet the rule and the insurer may reduce your payment.

You can also call a public adjuster to check this math for you.

A longer example with numbers and clear steps

Replacement cost to rebuild your home = $300,000.
Required insurance at 80% = $300,000 × 0.8 = $240,000.
You carried $180,000 in insurance.
A storm caused $90,000 in covered damage.
Deductible = $2,000.

Step 1: Ratio = $180,000 / $240,000 = 0.75.
Step 2: Adjusted loss = 0.75 × $90,000 = $67,500.
Step 3: Insurer pays = $67,500 − $2,000 = $65,500.

You see the insurer paid less than the full $90,000 loss. The coinsurance rule reduced the payment.

Table showing how underinsurance changes the payment

Replacement cost	Required 80%	Insurance carried	Loss	Deductible	Insurer pays
$300,000	$240,000	$240,000	$90,000	$2,000	$90,000 − $2,000 = $88,000
$300,000	$240,000	$180,000	$90,000	$2,000	(180k/240k)×90k − 2k = $65,500
$300,000	$240,000	$120,000	$90,000	$2,000	(120k/240k)×90k − 2k = $43,000

You can see how the payment drops when the insurance carried falls below the required amount.

How mortgage lenders can affect your coverage

Your lender usually requires you to carry insurance. The lender wants the home protected. The lender may require enough insurance to cover the loan amount. That coverage does not always equal 80 percent of the replacement cost. You must still check whether you meet the 80 percent rule. You may need more coverage than the lender requires.

Why the market value and replacement cost differ

Market value equals what a buyer pays for your home today. Replacement cost equals the price to rebuild. Builders may charge more to meet current building codes. The rebuild can cost more than market value, or sometimes less. You need a professional rebuild estimate. You should not assume the market value equals the rebuild cost.

How permits and building code upgrades increase the rebuild cost

Codes change after storms. Cities require new materials and stronger methods. Those code upgrades can raise the rebuild cost. You may need higher coverage to meet the 80 percent rule when codes change. A public adjuster can list code upgrade costs as part of the claim. You can also add a building code endorsement to the policy.

Special rules for older homes and items

Older homes have older items. Insurance may treat those items differently. The insurer may use actual cash value for old items. The insurer may pay replacement cost for the building but depreciate older fixtures. You should read your policy and ask a public adjuster to explain how depreciation works.

How to check if you meet the 80 percent rule today

You call a local builder or appraiser for a rebuild estimate.
You multiply that number by 0.8 to get the required insurance.
You compare your policy limit to the required insurance.
You call a public adjuster to confirm the numbers and to discuss endorsements.

You can call Otero Property Adjusting & Appraisals for a free inspection. Otero inspects property damage and checks coverage. Otero reviews your policy and the rebuild cost. Otero can help you correct underinsurance.

How partial losses interact with the rule

You suffer a partial loss like a damaged kitchen or part of the roof. The insurer still looks at the total replacement cost for the home when applying the coinsurance rule. The insurer does not only look at the damaged part. That rule means you must have enough insurance for the whole home, not just for the damaged part.

Mistake to avoid: insuring only the mortgage balance

You pay off a mortgage gradually. Your mortgage balance falls. You may reduce the homeowners insurance to match the balance. That choice can leave you underinsured. You must insure the replacement cost, not the mortgage balance. Ask a public adjuster to explain the proper amount.

Your options if you are underinsured

You can increase coverage at renewal. You can add endorsements that reduce coinsurance impact. You can buy guaranteed replacement cost if available. You can document the true rebuild cost and ask the insurer to consider that number during the claim. A public adjuster can help with this process.

Examples of different losses and the 80 percent rule

Hurricane damage: The roof and siding get ripped. The rebuild cost rises. You meet the 80 percent rule if you carried enough coverage. If you did not, the payout reduces.
Water damage from a pipe leak: The damage looks small. The repair reveals hidden damage in walls and floors. The insurer still checks total replacement cost and applies the coinsurance rule if required.
Kitchen fire: The fire damages cabinets and structure. The insurer checks whether the home carried enough total coverage to avoid coinsurance.
Mold after a leak: The insurer investigates the cause. Mold remediation may be costly. The coinsurance rule may affect payment if you did not carry enough coverage.

In each case, a public adjuster can document the full scope and explain how the 80 percent rule affects payment.

How to prepare your policy before a storm season

You check your coverage before hurricane season. You confirm the replacement cost estimate. You update your coverage if prices rose. You add endorsements like ordinance or law coverage if needed. You ask a public adjuster for a policy review. A short review can save you money and trouble after a loss.

What questions to ask your insurer or adjuster about the 80 percent rule

What replacement cost did you use for my home?
How did you calculate the required 80 percent amount?
Do you apply coinsurance if I meet certain conditions?
Do I have endorsements that affect payment?
Can you explain the math used to calculate my payout?

You should ask these questions in writing. You should keep copies of all answers. A public adjuster can help you ask the right questions.

How an appraisal can help when you disagree with the insurer

You may disagree with the insurer’s replacement cost estimate. Your policy may offer an appraisal clause. You can hire an independent appraiser. The appraisers can review the rebuild cost and make an independent estimate. If the appraisal shows a higher replacement cost, the required 80 percent number changes and your payout may increase.

Why local pricing matters in Florida

You live in Florida. Labor and materials vary by county and city. Hurricane recovery raises local demand for contractors. Local pricing can exceed national averages. A local public adjuster knows local costs. Otero operates in Pensacola and across Florida. Otero uses local pricing to create accurate rebuild estimates.

Cost vs. value: what you should think about

You may think about cost and value differently. Cost equals what it takes to rebuild the home. Value equals what the home sells for. You must insure for cost to rebuild. If you insure for market value only, you risk coinsurance. A public adjuster or appraiser can show you the rebuild cost and help you choose a proper limit.

The role of inspections and estimates

You can get a pre-loss inspection. You can get a post-loss inspection. Both inspections help. A pre-loss inspection checks coverage and rebuild cost. A post-loss inspection documents damage and cost. Otero provides post-loss inspections for free and helps you negotiate the claim.

How you can avoid unpleasant surprises

You read your policy carefully. You update your coverage when costs rise. You document damage and protect the property after loss. You call a public adjuster early for help. You keep receipts and communication records. These steps reduce surprises at claim time.
