Factors Affecting Professional Liability Insurance Costs in Arizona
Professional liability insurance costs vary based on several factors:
Industry and Services
Medical practices and law firms typically pay higher premiums than consulting firms due to the potential for significant financial loss from malpractice claims.
Location
A business's location affects insurance premiums, with areas that have high claim rates or litigation-friendly environments leading to increased costs.
Number of Employees
The more employees a business has, the greater the chance of mistakes or oversights, which can lead to increased claims and consequently higher insurance premiums.
Coverage Limits
Choosing higher coverage limits, such as $2 million over $1 million, increases the insurer's liability, which is reflected in higher premium costs.
Policy Add-Ons
Adding extra coverages like general liability or specific endorsements to a policy will raise the overall cost, as these enhancements extend beyond basic coverage.

How We Rated the Best Professional Liability Insurance Companies in Arizona
MoneyGeek created a scoring system to compare business insurance companies across six metrics and ranked them based on their scores for Arizona. We chose these companies based on their broad national coverage and ability to provide an online quote.
Small Business Sample Profiles:
We gathered quotes for two types of software development companies in Arizona:
- An LLC with five years in business, 20 employees, $5 million in annual revenue and $1,250,000 in annual payroll costs.
- A sole proprietorship with five years in business, no employees, $500,000 in annual revenue and no payroll costs.
MoneyGeek’s Scoring System:
In our unique scoring system, companies can earn up to five points in each of the six categories. We then use these category scores to calculate an overall MoneyGeek score out of 100. We applied the following weightings to score insurers:
- Affordability for LLCs: 55%
- Affordability for sole proprietors: 5%
- Customer satisfaction: 25%
- Financial stability: 5%
- Coverages offered: 5%
- Online quote process: 5%
Each company’s score incorporates:
- Customer satisfaction data from the National Association of Insurance Commissioners (NAIC) customer complaint index (we reviewed annual complaint data from 2020 to 2022, the most recent year available)
- Financial strength ratings from AM Best
- Cost data obtained through online quotes, based on the monthly and yearly cost of a professional liability policy with a $1 million per occurrence limit, $1 million aggregate limit and $5,000 deductible
- How many minutes it took to complete an online application and receive a quote from each company
- The variety of each company’s coverage offerings and the number of core business insurance coverage options available to customers
Quote Gathering Process
Three companies on our list — NEXT, The Hartford and Thimble — require business owners to bundle professional liability insurance with general liability coverage when obtaining an online quote. Thimble also includes cyber liability insurance in its bundle.
For these three companies, we gathered bundled quotes and quotes for general liability insurance. We then subtracted the cost of general liability insurance from the bundled amount to determine the cost of professional liability coverage on its own.
