Turn a percentage increase into annual and monthly dollars.
Use a current quote when possible. The selected increase is your stress scenario—not a forecast of what an insurer will charge.

- Is dwelling coverage based on a current replacement-cost estimate—not market value?
- Which losses trigger standard, wind/hail or named-storm deductibles?
- How are roof, ordinance/law, water backup and matching materials settled?
- Are hurricane/wind terms separate, and is flood excluded from the homeowners policy?
TRANSPARENT FORMULAS
Keep premium and deductible stress separate.
Monthly premium increase = annual premium × selected increase ÷ 12.
Percentage deductible = Coverage A × deductible percentage.

EVIDENCE ORDER
A benchmark starts research. A current address quote starts planning.
State averages do not price a roof, construction type, claims history, mitigation, coverage package or exact address. This tool never converts ZIP or climate into an insurability verdict.
HOME INSURANCE SHOCK FAQ
Use a scenario without turning it into a prediction.
The written quote and policy control. This calculator only tests the amounts and assumptions entered.
What does a home insurance shock calculator test?
It applies an editable increase to a current annual quote or a clearly labeled historical state benchmark, then compares the largest deductible you enter with liquid savings. It is a household cash-flow screen, not a quote or underwriting result.
How is a percentage home insurance deductible calculated?
For the selected standard or wind deductible, the tool multiplies the entered Coverage A limit by the deductible percentage. Coverage A is the dwelling limit from the quote or declarations page, not the home's market value.
Should I use a state average or an address-specific quote?
Use a current address-specific written quote when available. A state average is only a broad historical starting point and cannot price the roof, construction, claims history, mitigation, coverage package or exact address.
Does the calculator predict my future premium or a claim?
No. The increase is a scenario you choose, not a forecast. The deductible test also does not predict whether a loss will occur, whether it will be covered or how a carrier will settle it.
What should I verify before relying on the result?
Confirm Coverage A, standard and wind or named-storm deductibles, roof settlement, exclusions and sublimits, ordinance or law, water backup, flood treatment, binding status and the quote date with the policy documents or a licensed agent.
