What Does an All Perils Deductible Mean in Home Insurance?
It's one flat deductible for any covered loss, instead of a separate, often higher, amount for wind or hail.

How the number is set
An all perils deductible is usually a flat dollar amount, like $500, $1,000, $2,500 or $5,000, not a percentage. You pick it when you buy the policy. Your declarations page shows the exact figure, since lenders checking your binder will expect to see it stated plainly.
What it replaces
Some policies split out a separate, often percentage-based, deductible for wind, hail or hurricane damage, commonly 1% to 5% of your dwelling coverage. An all perils deductible does away with that split, so the same flat amount applies whether a tree falls on the roof or a pipe bursts.
Why the amount matters now
A higher deductible lowers what you pay for the policy, which can help if you're already stretching to cover closing costs. A lower one costs more upfront but means less out of pocket if something goes wrong right after you move in, before you've built savings for repairs.
What your lender actually needs
Lenders care that the deductible is reasonable enough not to leave the house underinsured in practice, not which type you pick. The binder you send before closing should state the deductible clearly alongside the dwelling coverage amount, since both appear on the same declarations page.
Two quotes with the same dwelling coverage can carry very different deductible setups, one flat, one split out for wind or hail at a percentage that runs higher than it looks on paper. That difference changes what you'd actually pay after a claim, not just what you pay monthly. Comparing quotes side by side before closing shows which structure fits the cash you'll have on hand once the house is yours.
How do you decide which deductible to pick before closing
There's no single right number here, but the choice comes down to what cash you'll have on hand right after closing versus what you're comfortable paying each month. If you're putting most of your savings toward a down payment and closing costs, a $500 or $1,000 deductible means less to find if a pipe bursts in your first few months. You'll pay more for the policy itself in exchange. A $2,500 or $5,000 deductible lowers that monthly cost, which can matter if you're already stretched. But it means you'd need that much ready if something happens before you've rebuilt a cushion of savings.
One way to think about it is how many years you expect to stay in the house without filing a claim, weighed against the gap between deductible options. Most homeowners never file a claim in a given year, so a higher deductible often saves more over time than it costs if something does go wrong. That math changes if the house is older, has an aging roof, or sits somewhere prone to storms, where a claim is more likely sooner rather than later.
Worth checking before you lock in a number is whether your state or your insurer still splits out a separate deductible for wind, hail or hurricane damage, even on a policy marketed as all perils. Some states require that split for certain coverage types, regardless of what the base policy looks like otherwise. If that applies to your house, the percentage-based amount, often 1% to 5% of your dwelling coverage, could run higher than your flat deductible. It's worth asking directly rather than assuming the flat number covers everything.
Once you've picked a deductible, that figure plus your dwelling coverage amount are the two numbers your lender will look for on the binder. If you're unsure which to choose, ask what the premium difference actually is between two deductible levels before deciding. Sometimes the gap is small enough that the lower deductible is worth paying for. Sometimes it's large enough that the higher one is the clear choice. Either way, your declarations page will state the final number plainly once the policy is in place.
Can you change your deductible after the policy starts
Yes. The deductible you pick before closing isn't locked in for as long as you own the house. Most insurers let you raise or lower it at renewal, and sometimes mid-term if you ask. If you chose a lower deductible to protect your cash right after closing, you can move to a higher one once you've built up savings, and your premium should drop to reflect that.
The timing matters more than people expect. Changing your deductible mid-term, after you've already paid for the policy period, sometimes means a short gap or an adjusted bill rather than an instant switch. Changing it at renewal is simpler, since the new deductible just applies to the next term from the start. If you know you'll want to raise it in a year, it's worth asking now whether your insurer prorates changes or waits for renewal, so you're not surprised either way.
One thing that doesn't change with timing is a claim already in progress. If something happens to the house before you've adjusted the deductible, the amount on your declarations page at the time of the loss is the one that applies, not whatever you might switch to later. That's part of why getting the number right before closing matters more than getting it perfect. You have mentioned the chance to revisit it, but you're the one paying out of pocket if a claim lands while an outdated deductible sits on the policy.
Lenders generally don't get involved once the loan has closed, so changing your deductible later is between the reader and the insurer. The one exception is if the change is large enough to affect whether the dwelling coverage still meets what the mortgage requires, which it rarely does since deductible and dwelling coverage are separate numbers. Most people find it simpler to treat the deductible chosen before closing as a starting point, then revisit it once a year at renewal, when the declarations page already lists the current figure for comparison.
