Home and auto bundle savings calculator

A bundle discount looks good on its own, but it is measured against the same company's separate prices, not against the market. The calculator confirms what the bundle saves, then tests it against the best separate quotes you can find, because a modest discount from an expensive insurer can still lose to two cheaper policies.

How to use it

Ask one company for four annual premiums: home alone, auto alone, and each policy priced inside the bundle. Make sure the coverage is identical each time, meaning the same dwelling limit, deductibles and endorsements on the house and the same limits on the car. Enter them in the first four boxes. If you have shopped elsewhere, enter the best separate home quote and the best separate auto quote in the optional boxes, and leave them blank if you have not. Results update as you type.

How the math works

"Separate" is home alone plus auto alone, and "bundled" is the bundled home plus the bundled auto. The headline saving is separate minus bundled, shown in dollars and as a share of the separate total. If you fill in either outside quote, the tool also totals the best separate quotes, using the same company's separate price for any box you left blank. It then warns if that total beats the bundle, or confirms that the bundle wins, in each case by the difference in dollars.

Say, hypothetically, home alone at $2,400 and auto alone at $1,800, against a bundle of $2,150 and $1,650. Separate is $4,200, bundled is $3,800, and the bundle saves $400, or 9.5%. Now suppose another company quotes $2,050 for the house and $1,700 for the car. That is $3,750 for two policies from two companies, $50 a year less than the bundle, if the coverage matches.

What it assumes

The tool builds in no discount percentage. The 9.5% above is arithmetic from the example prices, and every number is an editable example rather than a market figure. It works with annual premiums and does not include installment fees, taxes or any change in rates at renewal.

Where it stops being right

The comparison is only as good as the coverage match. If the bundle quote carries a higher deductible or a lower dwelling limit than the separate quote, the saving is partly a coverage cut (how to compare homeowners insurance quotes). If you enter only one outside quote, the other half of the "best separate" total falls back to the same company's separate price, so the total mixes sources. A tie reports that the bundle beats the best separate quotes by $0.

Price is not the whole decision. Claims service, financial strength and the agent matter, and two policies with two companies mean two renewals and two claims desks. The tool's own footnote raises one possible advantage of a single company: whether a loss that damages both car and house, such as a fallen tree, triggers one deductible or two. Policies differ, so ask. If you later move one policy, the discount on the other usually goes with it.
