Bundling home and auto: check the total, not the discount

Putting your car and your home with one insurer often earns a discount. Whether it saves money depends on what each company charges before the discount.

Bottom line

Insurers that sell both home and auto coverage often give a discount when you buy both from them, and state regulators list it among the common discounts. Wisconsin's insurance office puts the package discount at up to 15%. But the discount comes off that company's own price, so a bundle can still cost more than two separate policies from different companies. Price the bundle and the split side by side, on the same coverage, and pick the lower total.

How a multi-policy discount works

When you buy two or more policies from the same insurer, the company may lower the price of one or both. It is often called a multi-policy, multi-line or package discount. Each company decides how large it is, which policies count and whether it comes off the auto premium, the home premium or both. There is no single national rule.

State regulators name it in their consumer guides without setting an amount. The Wisconsin Office of the Commissioner of Insurance says a package discount for home and auto with one insurer can run up to 15%; see car insurance costs in Wisconsin. The Texas Department of Insurance lists a discount for other policies with the same company, the Maine Bureau of Insurance lists auto-home packages, and the Ohio Department of Insurance and the Utah Insurance Department list home and auto with one company among the discounts insurers commonly offer.

Which policies count. Homeowners and auto is the pairing regulators mention. A company may also count a renters or condo policy, or other lines it sells; ask before you assume.
Where the discount lands. Some companies split it across both policies, others apply it to one. Ask for the dollar amount on each policy, not only the percentage.
How long it lasts. The discount stays only while both policies stay with the company. Cancel one and the other can lose it; ask when that takes effect.

Why a bundle isn't always cheaper

A discount is a percentage of one company's price. If that company starts higher than its competitors, the discount can leave you paying more than you would with two separate companies. The example below uses made-up numbers for one year of coverage.

One year of home and auto coverage, bundled or split between two companies (example)
Policy	Bundle at Company A	Split: B for auto, C for home
Auto	$1,500 − 10% = $1,350	$1,250
Home	$1,700 − 10% = $1,530	$1,550
Total for the year	$2,880	$2,800

Here the bundle saves $320 against Company A's own prices, and the split still comes out $80 lower. Change the numbers and the bundle can win just as easily. For scale, the NAIC's latest state-by-state data put the 2023 U.S. average at $1,438 for a car carrying liability, collision and comprehensive, so a few percentage points either way on two policies can add up to real money.

What else changes when you bundle

Price is the main question, but tying two policies to one company changes a few other things. None of them is a reason to avoid a bundle on its own; they are worth knowing before you move both.

Leaving gets harder. If one policy jumps at renewal, moving it can cost you the discount on the other. Price both again before you decide.
Your lender needs to know. If your homeowners premium is paid from a mortgage escrow account, tell the lender when you switch companies so it pays the new one and the old policy isn't left unpaid.
Switching midterm needs care. Start the new policies before you cancel the old ones, in writing, and ask for a refund of any unused premium. Our guide to switching insurers without a gap walks through the order.
Other discounts still apply. A bundle doesn't replace safe-driver, multi-car or safety-equipment discounts. Ask each company for the full list it applied.

When to bundle and when to split

A bundle makes sense when its total is lower than the lowest pair of separate policies on the same coverage, or when the difference is small and you value one company, one bill and one renewal. A split makes sense when one company is clearly cheaper for one line and expensive for the other.

The answer can change from year to year. Home and auto prices move on different schedules, and a company that prices one line well this year may not next year. A good time to re-check is when either policy renews or when something changes, such as a move, a new car or a new driver in the household; our page on when to shop for car insurance lists the usual triggers.

If the bundle wins, keep the deductibles where you can afford them. A higher car deductible can save more than the bundle discount itself; the deductible break-even calculator shows how many claim-free years it takes to come out ahead.

How to price a bundle

Write down your current coverage for both policies: limits, deductibles and add-ons, from the declarations pages.
Ask two or three companies for a bundle quote on that coverage, and ask each one for the auto and home prices without the bundle too.
Price the split. Take the lowest auto quote and the lowest home quote, even if they come from different companies, and add them up.
Compare the totals for a full year, not the monthly figure or the size of the discount.
Switch in the right order: new policies first, then cancel the old ones in writing and tell your mortgage lender.

Questions drivers ask

Is bundling home and auto always cheaper?

No. The discount comes off one company's price. If that company starts higher, two separate policies from different companies can cost less in total. Compare both totals on the same coverage.

How much is a home and auto bundle discount?

Each insurer sets its own. Wisconsin's insurance office says a package discount can run up to 15%; no state we checked requires a set amount. See Wisconsin car insurance costs.

Can I bundle renters insurance with car insurance?

Some companies count a renters policy toward a multi-policy discount, and some don't. Ask which policies count and what the discount is worth in dollars.

What happens to my discount if I cancel one policy?

The remaining policy can lose the multi-policy discount. Ask the insurer when the change takes effect and what the new price will be before you cancel.
