  • The claim is what the board pays and charges back through your premium. The hidden costs are yours alone: no insurance covers them.
  • WCB-Alberta rates larger employers on three of the last four years of claim costs against their industry, up to 40% either way (more for repeat poor performers); smaller employers on their lost-time claims over five years.
  • An estimate to plan with. It leaves out what can't be priced: the worker's pain and their family's, and what the crew goes through.

Prevent the next one

One incident like this pays for a lot of prevention.

TruStar Connect puts hazard assessments, inspections, incident investigations, corrective actions and training on every phone on site, offline, so the near miss gets reported and fixed before it becomes a claim.

Enter an incident, or start from your province's average lost-time claim, and this calculator adds up what it really costs: the claim, the hidden costs under the waterline, the premium increase, and how much extra revenue the business has to bring in to pay for it at its profit margin.

The cost below the waterline

The claim is the part everyone sees. Underneath it are the costs the employer carries alone: the shift that stopped, the supervisor's week, the investigation, the overtime, the replacement who has to be found and trained, the work that slows down while the injured worker comes back. No insurance covers them, and they come straight out of profit.

  • Price the hours at their full cost: wage plus benefits and payroll costs.
  • Count the people who stopped work, not only the one who was hurt.
  • A lost-time claim stays on your experience rating for three years or more.
Every dollar of cost takes many dollars of sales
At a 5% margin, a $100,000 incident takes $2,000,000 in new sales just to break even. Prevention is almost always cheaper.

Frequently asked questions

How much does a workplace injury cost in Canada?
The average lost-time claim cost $56,840 in Alberta, $40,717 in BC, $35,702 in Ontario and $37,936 in Quebec in 2024 (AWCBC, benefit costs per lost-time claim, including expected future costs). The hidden costs to the employer come on top: supervisor and investigation time, overtime, replacement and training, lost output and damage, commonly estimated at 2 to 4 times the claim.
What are the indirect costs of an incident?
The costs no insurance covers: the rest of the shift, first aid and transport, work stopped round the incident, supervisor and management time, the investigation, paperwork and claim management, overtime to cover, hiring and training a replacement, lost output on modified work, damaged equipment and material, delays and lost bids, and legal costs or fines.
How much in sales does it take to cover the cost of an injury?
Divide the total cost by your profit margin. At a 5% margin, an injury that costs the business $100,000 takes $2,000,000 in extra sales to pay for: every dollar of cost needs twenty dollars of revenue.
Does a claim raise my WCB premium?
Yes, through experience rating. WCB-Alberta rates larger employers on three years of claim costs against their industry, up to 40% either way; WorkSafeBC weighs three years of claims; the WSIB looks at six. A claim can cost more in premiums than the claim itself over those years.
