Iowa ranked # 1 in the United States for most affordable personal auto insurance, according to a recent study by the Insurance Research Council. The Insurance Research Council Affordability Index uses the ratio of average auto insurance spending to median household income. Based on the 2018 Affordability Index, auto insurance was the most affordable in Iowa, where households spent 1.02% of their income on auto insurance. Other states with low expense-to-income ratios in 2018 included North Dakota, Hawaii, New Hampshire, and Virginia. By far, the least affordable state in 2018 was Louisiana, with an index of 3.09%. The five least affordable states were Florida, Michigan, Mississippi, and Georgia. The data is used to measure and compare the affordability of auto insurance over time and across jurisdictions. “Affordable auto insurance is good news for the people of Iowa,” Iowa Insurance Commissioner Doug Ommen said in a statement. “With Iowa’s ability to reduce insurance costs and with a competitive market that offers many options for consumers, I look forward to Iowa continuing to be the leader in this area. “
