How to calculate your Massachusetts Workers' Comp Premium

To calculate your Massachusetts workers' comp premium, you need to consider a few main factors: the number of employees you have, the type of work they do, your payroll, your risk exposure, and your industry. The basic formula to estimate your workers' comp cost is as follows:

Workers' Comp Rate x (Payroll/$100) = Premium

Workers' Compensation Premium Formula

The classification code rate is determined by the National Council on Compensation Insurance (NCCI) or your state. You can find your rate in the chart above or ask an agent. 

Here’s an example of how it works

Let's consider a hypothetical example. Suppose you own a small retail store in Massachusetts with five employees. Your annual payroll is $250,000, and you have a workers' classification code rate of $1.28. 

Using the formula above, your workers' comp premium calculation would be:

$1.28 (Rate) x ($250,000/$100) = $3,200

In this example, your estimated workers' comp premium for 2024 would be $3,250 annually, or $271 monthly, plus taxes and fees.

Keep in mind that this formula provides a rough estimate of your workers' comp premium. 

To receive a more accurate quote, you should contact an insurance company specializing in workers' compensation coverage in Massachusetts. They will consider additional factors specific to your business and provide a tailored quote for your needs.

What other factors influence your Workers' Comp Premium in Massachusetts?


Another factor affecting your workers' compensation premium is the experience modification (ExMod) rate. ExMod is a value that assesses your business's history of claims in comparison to other businesses in the same industry. 

A higher ExMod means higher premiums, while a lower one can result in lower premiums. To maintain a low ExMod, make sure your employees are aware of potential hazards and encourage prompt incident reporting.

Safety programs

Implementing safety programs in your workplace can significantly impact your workers' compensation premium. 

A comprehensive safety program provides training, guidelines, and resources to create a safety-conscious work culture. This results in fewer accidents and minimizes insurance claims, leading to lower premiums.
