An optional feature that reduces your policy deductible by $100 each time the policy renews without a claim, up to the full deductible amount.
Pick your deductible as usual. Each claim-free renewal, $100 comes off what you'd actually pay in a loss. Stay claim-free long enough and the deductible can reach zero. It's loyalty rewarded in the currency that matters — not points, not a mug, but the check you don't write on the day something goes wrong.
Vanishing-deductible features exist on some auto policies. On condo and renters policies — products that often cost less per year than the deductible itself — it's nearly unheard of, and it changes the math of small claims: as the deductible shrinks, more of a modest loss is actually recoverable.
You take out a renters policy with an $800 deductible and add the shrinking-deductible option. Three renewals pass without a claim — you weren't doing anything except living your life — and the working deductible steps down: $700, $600, $500. In year four, a kitchen fire damages your cabinets and everything on the counters. When that covered claim settles, the deductible applied is $500, not the $800 on the front of the policy. Three years of nothing happening reduced what you owed on the day something did.
