Workers' Compensation · RTW Cost Analysis

What do your injuries really cost
your payroll?

The claim is just the tip. The real cost sits in the pay run — lost capacity, modified-duty inefficiency, replacement labour, overtime loading, and coordination time. Add as many workers as you need.

How each cost component is calculated

Six distinct cost drivers — each isolating the economic impact that sits around a workers' compensation claim, not the claim itself.

Lost Capacity

Full productive value of absent hours. Even if covered by comp, this capacity was gone.

absent_hrs × ordinary_rate

Modified-Duty Loss

Only the lost portion. 60% productivity = 40% lost. The productive share isn't a drain.

mod_hrs × (1 − prod%) × ordinary_rate

Replacement Premium

Only the rate difference above the injured worker's ordinary rate. Can be negative.

rep_hrs × (rep_rate − ordinary_rate)

Overtime Premium

Only the loading above ordinary time. 8 hrs at $38 at 1.5× = 8 × $38 × 0.5 = $152.

ot_hrs × ot_rate × (multiplier − 1)

Coordination Cost

Payroll, supervisor, and HR/RTW/safety time spent managing the claim.

Σ (role_hrs × role_rate)

Annualised Run-Rate

Scales the current pay-run drain by pay frequency — a run-rate indicator, not a forecast.

pay_run_drain × pay_runs_per_year
Important: This calculator estimates indirect productivity costs surrounding workers' compensation claims. It does not calculate statutory entitlements, premiums, or legal costs. Replacement labour premium may be negative where replacement workers cost less than the injured worker. WHA savings and ROI figures are based on published program outcomes; actual results depend on claim complexity, industry, workforce size, and program design.
