Note

This is generic arithmetic using the amounts, rates and factors you entered. It is not an insurance quote, a policy interpretation, or financial advice. No insurer rate, jurisdiction rule, statutory limit or policy wording is built in. Real premiums and payouts depend on underwriting, your policy's exact terms and exclusions, and applicable regulation; confirm with your insurer or a licensed professional.

Frequently asked questions

How does raising my deductible lower my premium?+

Insurers charge less when you agree to pay more out-of-pocket before coverage kicks in, since a higher deductible shifts more small-claim risk onto you and reduces the insurer's expected payout, which the calculator reflects as a premium reduction.

Is the premium savings guaranteed to exceed my added risk?+

No, the calculator shows the savings on premium, but you need to compare that saved amount to the extra amount you'd pay out-of-pocket if you actually file a claim, since a bad year could cost you more than you saved.

What's a realistic amount to expect in premium savings?+

Typically raising a deductible from $500 to $1,000 saves somewhere in the range of 10-15% on premium, though the exact percentage varies significantly by insurer, coverage type, and your claims history.

Should I only raise my deductible if I have savings set aside?+

Yes, financial advisors generally recommend keeping the deductible difference (or more) in an emergency fund, so that a claim doesn't create a cash-flow crisis even though it saves money on average over time.

Does this apply the same way to auto and home insurance?+

The underlying logic is the same for both, but home insurance sometimes uses percentage-based deductibles (e.g. 1-2% of dwelling value) rather than flat dollar amounts, which the calculator should account for separately from auto's flat-dollar deductibles.
