Is Bundling Home and Auto Insurance Worth It?
Discount ranges aggregated from Insurify, Insurance Pro Agencies, and JD Power-adjacent shopping study reporting; caveat sourced directly from III.
Bundling almost always saves something. Whether it saves you the most possible is a different question, and the industry's own research group says so directly.

What bundling actually saves, in real numbers
Bundling home and auto insurance with the same company typically saves 10% to 25% on the combined premium, according to an aggregation of multiple consumer finance and industry shopping-study sources.
If you rent rather than own, bundling auto with renters insurance saves less, roughly 5% to 10%, since renters policies are already comparatively small and there is less total premium for a discount to meaningfully move.
No single primary source publishes one exact, universal percentage for either bundle type, insurers set their own multi-policy discount internally, so these ranges reflect what shows up consistently across several independent sources rather than one authoritative number.
The caveat III itself makes, and why it matters
III, the insurance industry's own primary research and information group, confirms multi-policy discounts are real, but its own guidance includes a direct caution that is easy to miss: "you may save money buying from different insurance companies, compared with a multipolicy discount."
That single sentence is the whole nuance of this topic. A 15% discount off one insurer's home-and-auto rates is not automatically cheaper than buying home insurance from Insurer A and auto insurance from Insurer B separately, if Insurer A and B's individual rates happen to be low enough on their own.
The discount percentage tells you how much a specific insurer will shave off its own bundled price, not whether that bundled price beats the market.
To see how a specific bundle discount changes your own premium numbers, the multi-policy bundling discount estimator runs the math for both home-and-auto and auto-and-renters bundles.
How to actually shop this correctly
The only way to know for certain whether a bundle is your cheapest option is to get separate quotes. Price out home and auto individually from two or three insurers each, then compare that best combination against your bundled quote from a single insurer.
If the bundle comes close to or beats that total, take it, and get the added convenience of one bill and one point of contact as a bonus.
If a separately-assembled combination is meaningfully cheaper, the discount percentage on the bundle was real, it just was not applied to the lowest possible starting price.
Frequently asked questions
How much can bundling home and auto insurance actually save?
Aggregated across several consumer finance and industry sources, a home-and-auto bundle typically saves 10% to 25% on the combined premium, compared to buying each policy separately from different insurers.
An auto-and-renters bundle tends to save less, roughly 5% to 10%, since renters insurance is already a smaller policy with less premium to discount.
Does III, the insurance industry's own research group, actually recommend bundling?
It confirms multi-policy discounts exist, but it stops short of a blanket recommendation. III's own guidance explicitly cautions that "you may save money buying from different insurance companies, compared with a multipolicy discount," meaning the bundle discount from one insurer is not automatically the cheapest overall combination.
That caveat is easy to miss if you only hear "bundling saves money" without the rest of the sentence.
How do I know if my specific bundle discount is actually a good deal?
Get separate quotes from at least two or three other insurers for each policy individually, then compare that total against your bundled quote from a single insurer. If the bundle is not close to the lowest achievable total, the discount percentage alone does not tell the whole story, since it's a discount off that one insurer's own rates, not off the market's lowest rate.
Are there other advantages to bundling besides the discount?
Yes. Managing one insurer instead of two or three means a single bill, one login or app, and one point of contact if you need to file a claim or make a change.
Some insurers also apply a bundling-loyalty benefit that makes it slightly harder to be dropped after a single claim, since you represent more total premium to that insurer.
Neither of those is a guaranteed dollar saving, but they are real conveniences worth weighing alongside the discount percentage.
