Work out accident cost estimate instantly with clear inputs, formula shown and shareable results.
Direct costs, medical treatment and insured compensation, are the visible part of an accident. Indirect costs, investigation time, retraining, supervision, equipment damage, reputational and legal effort, typically run three to five times higher and are almost entirely uninsured. Lost production is added separately because it depends on the process rather than on the injury.
Total accident cost
Total = direct cost x (1 + indirect ratio) + production hours lost x hourly value
Total = direct cost x (1 + indirect ratio) + production hours lost x hourly value. Direct costs, medical treatment and insured compensation, are the visible part of an accident.
Because the hidden costs are diffuse: dozens of people spend time on investigation, reporting, cover arrangements and corrective action, and none of it appears on an insurance claim.
This calculator takes 4 inputs: Direct costs, Indirect to direct cost ratio, Production hours lost, Value of an hour of production. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
