Here's a simple way to potentially cut $150 from your annual insurance expenses: Raising your homeowners’ insurance deductible from $500 to $2,000 could lower your premiums by an average of 16 percent, according to a new report by InsuranceQuotes.com. Based on the average insurance premium of $978, that works out to more than $150 a year in savings.

Of course, that lower bill comes with some caveats. First, the amount you save could vary widely depending on where you live and other factors. In the new study, the savings from a higher deductible ranged from 41 percent for North Carolina homeowners to just 4 percent in Hawaii.

Second, a higher deductible means that you would be on the hook to pay more out of pocket before your insurance coverage kicks in if something happened to your home. Before making the switch, be sure you have enough money in your emergency savings to cover the total cost of the deductible.

“Consumers need to consider the bottom line before increasing deductibles,” Laura Adams, a senior analyst with InsuranceQuotes.com said in a statement. “While switching from a $500 deductible to a $5,000 deductible sounds appealing because it lowers home insurance premiums by an average of 28 percent, it could be a risky move for consumers who don’t maintain that much in savings.”

Increasing a deductible from $500 to $1,000 resulted in an average savings of 6 percent nationally, ranging from 25 percent in North Caorlina to a low of 1 percent in Kentucky.

As your deductible gets higher, it may become less likely that you file a claim at all, since doing so will push your premium up. A separate analysis last fall by insuranceQuotes.com found that a single claim—even if it’s denied—can hike your homeowners’ insurance by an average of 9 percent a year, which can amount to hundreds of dollars.
