How a workers compensation premium is built
Workers compensation starts from a rate for your business’s classification, the group of businesses that do similar work. That rate is applied to each hundred dollars of estimated payroll in the class, which gives a base premium. The insurer’s rating plans can then raise or lower it, and an experience modification adjusts it again if your business qualifies for one, as the California Department of Insurance guide to workers compensation explains.
The experience modification compares your own claims with those of the average employer in the same classification. Better than average earns a credit; worse than average carries a debit. NCCI, which publishes the plan used in most states, gives more weight to how often injuries happen than to what any one injury costs, so many small claims raise the modification more than one large claim with the same total. It’s recalculated each year from a rolling period of recent policy years, so an old claim drops out in time.
Report every injury to the insurer quickly. The Insurance Information Institute notes that the sooner the insurer hears of an injury and treatment starts, the sooner the worker tends to recover and get back to work.
Why the final bill can differ from the first one
Workers compensation and most general liability policies are auditable. The premium you pay at the start is a deposit based on estimated payroll, sales or units sold. After the policy ends, and sometimes during it, the insurer checks the books. If the actual figures are higher than the estimate, you owe more premium; if they’re lower, you’re due a return premium, as the Texas Department of Insurance explains.
An estimate as close to the truth as possible keeps that difference small. If payroll rises or falls sharply during the year, tell the insurer then. The California Department of Insurance notes that some workers compensation insurers offer monthly payroll reporting, and that a corrected estimate during the term lowers the chance of a large audit bill. Leave room in the budget for an audit charge.
Business owners policy, interruption and professional coverage
A business owners policy bundles general liability with property coverage, so its price follows both: the class of work and the value of the building and contents. Business interruption coverage is usually priced as part of the property coverage. Professional liability is priced on the profession, revenue and claims history.
The surest way to lower the cost of liability coverage is to compare the same limits and deductibles from more than one insurer, and to keep a clean claims history.
What sets the price of business interruption coverage
Business interruption coverage, also called business income coverage, pays lost income and continuing costs such as rent, loan payments and payroll while a damaged business is restored. The Insurance Information Institute lists what moves its price: the industry, the number of employees, the amount of coverage, past claims and the location. A restaurant may pay more than a real estate office, because of its greater fire risk and because an office can more easily work from somewhere else.
It pays only when the shutdown comes from damage the property policy covers. If the property policy excludes flood, a flood that closes your business isn’t covered by the interruption coverage either.
Two property quotes, two different policies
Replacement cost
Repairs or replaces at today’s prices
- No deduction for the age of what was lost
Actual cash value
Subtracts depreciation
- May not pay enough to rebuild
Two commercial property quotes with the same limit can cover different things. A basic form covers a named list of causes such as fire, lightning, windstorm and vandalism. A broad form adds more causes. A special form covers every cause of loss the policy doesn’t exclude.
The valuation matters as much. Replacement cost pays to repair or replace at today’s prices, while actual cash value subtracts depreciation and may not pay enough to rebuild. Most commercial property policies exclude flood, which needs its own policy. The Texas Department of Insurance guide to commercial property says to compare policies with similar coverage, because a cheaper policy might provide less of it. When one quote costs less, check its form and its valuation first.
What lowers the price without lowering the coverage
Keeps the coverage
Lowers the price and leaves the coverage as it was
- Following the insurer’s safety and disaster recommendations
- Fire detectors and security systems
Moves risk back to you
Lowers the price by leaving more of a loss to you
- A higher deductible
- A lower limit
Some changes lower the premium and leave the coverage as it was. Insurers may charge less for some coverages when you follow their recommendations on workplace safety and disaster preparation, and the Texas Department of Insurance notes that most insurers offer loss-control services to help. Fire detectors and security systems can earn discounts. If your business qualifies, a business owners policy usually costs less than buying the same coverages one by one.
Other changes lower the premium by moving risk back to you: a higher deductible or a lower limit can cost less, and leaves more of a loss to be paid from your own money. Before asking for a price, get your loss runs (the insurer’s record of your past claims) up to date, and write down the safety measures and training you have in place, so both are ready when an insurer asks.
How to get a real number
A real price comes from your own details: what your business does, its payroll, the limits a contract asks for and its claims history. Get those together, then ask me, or call me at (480) 228-0591. The business insurance page explains what each coverage does.
