Liability limits are the most consequential numbers on your policies and the ones people think about least, usually set years ago by whoever sold the policy and never revisited. Here’s a framework that takes ten minutes and actually fits your life.
Start with what’s at stake
A liability claim that exceeds your limits doesn’t politely stop at the policy ceiling. The excess comes from you: home equity, savings, brokerage accounts, and potentially garnished future wages. So the first number to know isn’t an insurance number at all; it’s a rough total of what a judgment could reach. Home equity plus savings plus investments, plus something for the earning years ahead.
If that total is meaningfully above your current limits, you’re self-insuring the difference, probably without having decided to.
Why minimums aren’t really coverage
Arizona requires 25/50/15: $25,000 per injured person, $50,000 per accident, $15,000 property damage. Those numbers keep you legal, and that’s all they do. A single serious injury produces medical bills that pass $25,000 in the first days, and $15,000 doesn’t replace the average new car you might hit. Minimum limits are best understood as license protection with a side of coverage.
A practical ladder
Early career, few assets: 100/300/50 on auto is a reasonable floor, cheap to reach from minimums, and protects the future income that is your actual net worth.
Homeowners with equity and savings: 250/500/100 auto plus $300,000 to $500,000 homeowners liability is the standard pairing, and it’s also the underlying requirement most umbrella carriers want to see.
Net worth past roughly half a million: add an umbrella. Base policies top out around $500,000, and an umbrella adds $1 million or more across both auto and home exposures for a few hundred dollars a year. From here, the rule of thumb is umbrella coverage at or above net worth, rounded up.
Risk multipliers: teen drivers, pools, dogs, boats, rental properties, long commutes. Each one nudges you up the ladder sooner.
The check that’s worth doing
Pull your declarations pages and read the actual limits, which routinely surprise people who assumed they had “full coverage” (a phrase that means physical damage coverage, not high liability limits). Then compare against the assets math above. If there’s a gap, price the fix before assuming it’s expensive; higher limits usually cost less than people expect, and we can quote the limit increase and an umbrella together.
