One of the best ways to get cheap car insurance is by comparing car insurance quotes — and the companies offering them. To get you started, NerdWallet looked at car insurance prices across the country for different driver profiles and coverage levels to find the cheapest rates. We’ve sliced the data in several ways to give you an idea of average costs and what factors might nudge your car insurance rate up — or even better, down.

In determining premiums and premium rate structures, insurers consider quantifiable factors, including location, credit scores, gender, occupation, marital status, and education level. However, the use of such factors is often considered to be unfair or unlawfully discriminatory, and the reaction against this practice has in some instances led to political disputes about the ways in which insurers determine premiums and regulatory intervention to limit the factors used.
Which companies have the cheapest auto insurance rates in Austin, Texas? We suggest 30 year old drivers in Austin compare quotes starting at Texas Farm Bureau, Progressive, and GEICO. Auto insurance in Austin can cost drivers $2,191 a year, which is about 6% less than average in the Lone Star state. These three companies, however, have car insurance rates 44% less than the Austin average.
At the same time, the first insurance schemes for the underwriting of business ventures became available. By the end of the seventeenth century, London's growing importance as a center for trade was increasing demand for marine insurance. In the late 1680s, Edward Lloyd opened a coffee house, which became the meeting place for parties in the shipping industry wishing to insure cargoes and ships, and those willing to underwrite such ventures. These informal beginnings led to the establishment of the insurance market Lloyd's of London and several related shipping and insurance businesses.[6]
Our research found that paying for car insurance in Houston can cost $2,881 per year, making it the most expensive city in our study of Texas auto insurance. Houstonians can potentially save money by considering Texas Farm Bureau, Progressive, and State Farm. These three companies' rates are 34-51% less than the average Houston auto insurance rate, according to our study.

Limited risk of catastrophically large losses: Insurable losses are ideally independent and non-catastrophic, meaning that the losses do not happen all at once and individual losses are not severe enough to bankrupt the insurer; insurers may prefer to limit their exposure to a loss from a single event to some small portion of their capital base. Capital constrains insurers' ability to sell earthquake insurance as well as wind insurance in hurricane zones. In the United States, flood risk is insured by the federal government. In commercial fire insurance, it is possible to find single properties whose total exposed value is well in excess of any individual insurer's capital constraint. Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates the risk into the reinsurance market.
Collision coverage is limited to the actual cash value of the vehicle, and requires a deductible, which is the amount you'll need to pay before receiving benefits. Higher deductibles lower your premium but increase the amount you must pay out of your own pocket if a loss occurs. Ask yourself how much you would be willing to pay on short notice in order to save on your premium, or talk to your agent.
There are also companies known as "insurance consultants". Like a mortgage broker, these companies are paid a fee by the customer to shop around for the best insurance policy amongst many companies. Similar to an insurance consultant, an 'insurance broker' also shops around for the best insurance policy amongst many companies. However, with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather than directly from the client.

Calculable loss: There are two elements that must be at least estimable, if not formally calculable: the probability of loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim.
Large number of similar exposure units: Since insurance operates through pooling resources, the majority of insurance policies are provided for individual members of large classes, allowing insurers to benefit from the law of large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London, which is famous for ensuring the life or health of actors, sports figures, and other famous individuals. However, all exposures will have particular differences, which may lead to different premium rates.
Marine insurance and marine cargo insurance cover the loss or damage of vessels at sea or on inland waterways, and of cargo in transit, regardless of the method of transit. When the owner of the cargo and the carrier are separate corporations, marine cargo insurance typically compensates the owner of cargo for losses sustained from fire, shipwreck, etc., but excludes losses that can be recovered from the carrier or the carrier's insurance. Many marine insurance underwriters will include "time element" coverage in such policies, which extends the indemnity to cover loss of profit and other business expenses attributable to the delay caused by a covered loss.
In the United Kingdom, The Crown (which, for practical purposes, meant the civil service) did not insure property such as government buildings. If a government building was damaged, the cost of repair would be met from public funds because, in the long run, this was cheaper than paying insurance premiums. Since many UK government buildings have been sold to property companies and rented back, this arrangement is now less common and may have disappeared altogether.

Note that USAA ranked in the first or second spot in almost all cities, but we've excluded them from this table because the company only serves military and affiliated members. Below is also a deeper dive by the largest cities of the most affordable insurers by age and marital status to give drivers a further idea of the going rates for auto insurance. We've excluded USAA from the city specific tables as well.


California’s insurance laws are uniquely consumer-friendly, according to many experts. A lot of that is thanks to Proposition 103, which was approved by voters in 1988 and immediately required insurers to roll back prices 20%. Proposition 103 also mandated that auto insurance rates be preapproved by the state’s department of insurance, among other regulations. Many of the laws detailed below are from Proposition 103, but not all.
To calculate the added cost in purchasing comprehensive and/or collision coverage we looked at annual insurance quotes for a 30 year old male from New York across four different insurance companies, and the ten best-selling vehicles in the US. We look at the range of rates you could pay from basic liability to policy plans with comprehensive and collision coverage. Collision typically costs more than comprehensive, although some companies require you to carry both rather than just one. Comparing quotes across at least three companies can get you lower car insurance rates.

Property insurance as we know it today can be traced to the Great Fire of London, which in 1666 devoured more than 13,000 houses. The devastating effects of the fire converted the development of insurance "from a matter of convenience into one of urgency, a change of opinion reflected in Sir Christopher Wren's inclusion of a site for 'the Insurance Office' in his new plan for London in 1667."[4] A number of attempted fire insurance schemes came to nothing, but in 1681, economist Nicholas Barbon and eleven associates established the first fire insurance company, the "Insurance Office for Houses," at the back of the Royal Exchange to insure brick and frame homes. Initially, 5,000 homes were insured by his Insurance Office.[5]

Data was obtained from the Texas Department of Insurance for a thirty year old single male driver across 78 cities. He owns his car and uses it primarily for work purposes, averaging about 12,000 miles annually. Insurance policies include Texas’s minimum auto insurance liability requirements: $30,000 for bodily injury liability per person (up to $60,000 per accident), and $25,000 of property damage (30/60/25 coverage) liability insurance, 50/100/50, as well as 100/300/100. Car insurance costs are based on a 2011 Toyota Camry four-door sedan, with 2.5 liter/4 cylinder engine.
Insurers will often use insurance agents to initially market or underwrite their customers. Agents can be captive, meaning they write only for one company, or independent, meaning that they can issue policies from several companies. The existence and success of companies using insurance agents is likely due to improved and personalized service. Companies also use Broking firms, Banks and other corporate entities (like Self Help Groups, Microfinance Institutions, NGOs, etc.) to market their products.[30]
Collision and comprehensive insurance are two optional types of auto insurance where your insurer pays for repairs to your vehicle. While there are other optional auto insurance coverages, liability, comprehensive, and collision are three of the most common. These coverages work hand-in-hand to repair or replace most of the damages to your car. It's important to know the difference, and make sure you're adequately covered.
