In 1888, a Collin County settlement that had already been rejected twice for a post office name — first as a copy of Decatur, then stuck with the placeholder "Maxwell’s Branch" — finally got a name that stuck when a local landowner named Murphy donated the right-of-way for a railroad depot. The town kept the name through seven decades of cotton farms before incorporating as a city in 1958. Car insurance in Murphy, TX has nothing to do with that old depot, but the city that grew up around it still doesn't price quite the way its modern reputation suggests.

The average policy here runs about $232 a month, roughly $2,788 a year, based on 2026 insurer rate-filing data — a touch above the Texas full-coverage average of $2,751. For a city with Murphy's income profile, that number raises a fair question.

What Murphy Drivers Actually Pay

Citywide rate data puts the Murphy average at roughly $2,788 a year, just above the statewide full-coverage figure of $2,751. The cheapest policies available in the city run closer to $861 for a six-month term, about $1,722 a year, which means the spread between the average driver's bill and the best rate on the market is close to 40%. That gap is wider than it is in most of the suburbs around it.

The Income Paradox

Murphy's median household income of roughly $175,699 puts it ahead of well-known high-income neighbors, and insurers generally treat higher income as a proxy for lower claims frequency and stronger credit-based insurance scores — a legal rating factor in Texas. On paper, that should push Murphy's average below the state figure the way it does in nearby Sachse.

It doesn't, at least not yet. Murphy is a small city of about 21,000 people, which means fewer carriers actively compete for business block by block than in a market the size of Plano or Frisco next door. Less local competition tends to leave citywide averages closer to the statewide norm even when the income data alone would predict a bigger discount.

FM 544 and the Commute

FM 544 is Murphy's main through-road, cutting east-west across the city before linking toward Plano and Wylie. Most Murphy commuters use it to reach US-75 in Plano, about six miles to the west, or the President George Bush Tollway in Richardson, roughly five miles south.

  • FM 544: Signalized, two-lane-in-places arterial — the kind of road that generates rear-end and lane-change claims more often than a limited-access highway.
  • US-75 (Central Expressway): Reached via a six-mile drive west through Plano; faster once you're on it, but the approach runs through surface-street traffic.
  • President George Bush Tollway: About five miles south in Richardson, the limited-access option for commuters headed toward Dallas.

A commute that stays on FM 544 rather than reaching the tollway tends to rack up more of the low-speed claims that keep liability pricing from falling as far as a city's income might otherwise suggest.

Coverage Rules and Getting a Better Rate

Murphy follows the same 30/60/25 liability floor required everywhere in Texas: $30,000 in bodily injury coverage per person, $60,000 per accident, and $25,000 for property damage. Insurers must offer uninsured/underinsured motorist coverage, which you can only decline in writing — worth keeping given that roughly 14% of Texas drivers carry no insurance at all. Our uninsured motorist coverage guide covers what that protection actually pays for.

Given the nearly 40% spread between Murphy's average and its cheapest available policy, get quotes from at least three carriers before renewing rather than assuming a high-income ZIP code already got you a good deal. Ask whether each insurer weighs credit-based scoring heavily and whether a documented FM 544-only commute qualifies for a low-mileage discount. Our premium-cutting guide covers the rest of the discounts worth asking about.
