What makes one Twin Cities suburb cheaper to insure than another? Is it the roads, the people, or just luck? In Plymouth, the answer is boring and specific: money and crime data, mostly, with one highway interchange messing up an otherwise clean story.

Full coverage here runs about $2,240 a year. That's $187 a month, roughly $174 below Minnesota's $2,414 statewide average. Drivers in Minneapolis pay $2,673. Saint Paul residents pay $2,740. Plymouth pays neither.

How Much Does Car Insurance Cost in Plymouth?

Full-coverage policies average around $2,240 a year. Minimum-coverage policies come in well under the state's $602 average too, typically landing somewhere in the high-$40s a month rather than the low-$50s.

Neither number is the cheapest in the metro. Neither is close to the most expensive, either. Plymouth sits in the affordable middle of the Twin Cities suburbs, and the reasons why aren't a mystery.

Why Plymouth Prices Lower Than the Metro

Median household income in Plymouth is $136,534. That's not a typo. It's roughly double the statewide figure, and 45% of Plymouth households clear $150,000 a year.

Crime runs the other direction. Plymouth's overall crime rate sits about 43% below the national average, and violent crime has fallen sharply in recent years on top of that. Insurers don't guess at this stuff — fewer break-ins and fewer theft claims translate directly into lower comprehensive premiums, city by city.

Here's a detail that says it plainly: Midwest Family Mutual, a property and casualty insurance company, is headquartered right here in Plymouth. Insurers plant their offices where the risk math works for them, not where it doesn't.

The Highway 55 and I-494 Wrinkle

Every clean story needs a complication. Plymouth's is the Highway 55 and County Road 73 intersection, a stretch that's been flagged for years over the awkward merge it forces with the nearby I-494 interchange.

Drivers who cross that junction on a daily commute run into more backups and more rear-end claims than the rest of Plymouth sees. It's a corridor problem, though, not a citywide one. Neighborhoods around Medicine Lake and French Regional Park, well away from that interchange, don't carry the same exposure — and most of Plymouth's roughly 79,000 residents live in exactly those quieter pockets.

What Minnesota's No-Fault Rules Require Here

None of the above changes what the law demands. Plymouth drivers carry the same floor as everyone else in the state: 30/60/10 liability, $40,000 in Personal Injury Protection split evenly between medical and non-medical costs, and 25/50 uninsured/underinsured motorist coverage.

PIP pays your own medical bills first after a crash, regardless of fault — the core mechanic of Minnesota's no-fault system. A cheaper premium doesn't mean a smaller policy; it just means more of your budget is left over after you meet that minimum. For the full breakdown of what counts as adequate coverage above the floor, see our minimum vs. full coverage guide.

Putting the Numbers to Work in Your ZIP Code

Plymouth spans ZIP codes 55441, 55442, 55446, and 55447, and they don't all price identically. Here's what to actually do with that.

  • Check your specific ZIP: a quote for a home near the Hwy 55/CR 73 corridor won't match one from a block near Medicine Lake, even inside the same city.
  • Raise UM/UIM above the state floor: Plymouth's below-average premium leaves room in most budgets to do this without much added cost.
  • Ask about income and credit-based discounts: insurers often reward the same profile that already keeps Plymouth's baseline rate low.
  • Compare at least three quotes: the gap between carriers in a low-risk city like Plymouth can still run $30 to $50 a month.

The Minnesota Department of Commerce regulates every insurer writing policies in Plymouth and takes complaints if a quoted rate doesn't match what you're actually charged. For the statewide rules on PIP and liability limits, see our Minnesota car insurance guide.

So back to the original question — roads, people, or luck? Mostly people, a little bit of geography around one interchange, and not much luck at all. Car insurance in Plymouth is affordable because the underlying numbers say it should be, and that's about as unglamorous as an explanation gets.
