Premium calculation for small employers
You are considered a small employer if your average performance premium is $30,000 or less. This means your premium is not directly impacted by claims costs.*
Premium formula
The formula below shows you how your premium is calculated. Please refer to the table below for definitions of each component.
Premium
Average performance premium
Dust diseases contribution
Mine Safety Fund Premium adjustment
Safe Employer Reward
Performance discount
Apprentice incentive discount
Premiums adjustment contribution*
Catastrophic claims contribution
Where a Catastrophic claim contribution is applied, it is charged separately.
*eligibility for the Safe Employer Reward (SER) may be impacted by claim costs.
Calculation example

Annual wages bill $1,200,000
WIC Rate 2.200%
Average Performance Premium $26,400
Premium before adjustments $26,400
As the employer has no time loss claims or catastrophic claim charges in the last three policy periods, the Safe Employer Reward will reduce the premium by $1,980.
As an employee, Sarah slipped and injured her ankle at work, and was off work for 8 weeks. She returned on a graduated Return to Work plan.
Claims costs incurred $9,600 (Sarah's wages for 8 weeks)
As a small employer, Rob does not pay any additional premium for his claims experience, but will not be eligible for the Safe Employer Reward for three years from the next renewal.
