Deductibles Explained: Fixed, Percentage, and Split

A deductible is the portion of a covered loss you absorb before the insurer pays anything. Most people know that. What surprises them is that a policy can contain several different deductibles, that some are calculated as a percentage rather than a flat amount, and that which one applies depends on what caused the damage.

The fixed dollar deductible

The straightforward version. Your policy says $1,000, the covered damage is assessed at $8,000, and the insurer pays $7,000.

Two details that matter. First, the deductible applies per occurrence in most property policies, not per year — two separate covered losses in the same year each carry their own deductible. Second, it is applied to the covered amount after the insurer has determined what is covered, not to your repair bill.

The percentage deductible

This is the one that produces the unpleasant surprises, and it is now common in much of the country.

A percentage deductible is calculated against your dwelling coverage limit — the Coverage A figure on your declarations page — not against the size of the loss.

Percentage deductibles typically apply to specific named perils rather than to everything, and they commonly range from 1% to 5% — higher in some coastal areas. Your ordinary all-other-perils deductible remains a flat dollar amount.

The three that most often appear separately

Hurricane deductible

Triggered by a named storm, and the trigger definition is stated in the policy. It commonly attaches when the National Hurricane Center names a storm and remains in effect through a defined period after the watch or warning ends. Because the trigger is tied to an official designation, the same wind damage can carry different deductibles depending on whether the storm was named.

Windstorm or wind/hail deductible

Applies to wind damage generally rather than only to named storms, common in areas exposed to severe thunderstorms and hail. Often a percentage.

Earthquake deductible

Earthquake coverage is normally a separate policy or endorsement, and its deductible is almost always a percentage — frequently in the range of 10% to 25% of the dwelling limit, which is substantially higher than most people expect.

Split and calendar-year deductibles

Some policies use a split deductible: one figure for most perils and a different one for a specified peril. Health insurance and some commercial policies may use a calendar-year deductible, where amounts accumulate across the year rather than resetting per event.

Health plans add further layers: separate deductibles for medical and prescription coverage, individual versus family thresholds, and an out-of-pocket maximum that is a different figure from the deductible.

Where to find yours

The declarations page lists every deductible that applies. Look for a section headed "Deductibles" and read every line, because a policy with three is not unusual.

What to note down:

• The all-other-perils deductible, usually a flat amount.
• Any percentage deductible, and which peril triggers it.
• Your Coverage A dwelling limit, since percentage deductibles are calculated from it.
• The actual dollar figure each percentage produces. Do the multiplication now and write it down.

How the deductible interacts with the settlement

Order of operations matters, and it is not always intuitive. Broadly, the insurer determines what is covered, applies any depreciation if the settlement is on an actual cash value basis, and then subtracts the deductible.

On a replacement cost policy, this is why an initial payment can look low: it is the actual cash value less the deductible, with the recoverable depreciation held back until repairs are completed and documented. That withheld amount is generally payable on proof of completion — but you have to know it exists and claim it, and there is usually a time limit.

Two situations where the deductible changes the decision

These are observations about arithmetic, not recommendations.

Small losses. When the estimated damage is close to the deductible, the net recovery may be small relative to the effect a claim can have on future premiums and on your CLUE report, which insurers consult when pricing. The calculation is yours to make with your own numbers.

Multiple losses in one year. Because property deductibles usually apply per occurrence, two storms in a season mean two deductibles. In a percentage-deductible household that can be a significant figure.

Mortgages and minimum deductibles

If your home is mortgaged, the lender may impose limits on how high a deductible you can carry, sometimes expressed as a maximum percentage of the loan or of the dwelling value. Lenders may also require specific coverage in designated flood zones. Before changing a deductible on a mortgaged property, the loan documents are the place to check.

What we are not saying

We are not telling you what deductible to carry. That depends on your savings, your risk exposure, the premium difference in your market, and your own tolerance — and we have no way of knowing any of those.

What we are saying is that a percentage deductible is calculated from your dwelling limit rather than from your loss, that many policies contain more than one deductible, and that the time to find out which applies to you is before a storm is named.
