Safety & Workforce worked example

Safety ROI Calculator with upfront safety program investment of 187,500 $: a worked example

What does the result look like when upfront safety program investment reaches 187,500 $? The full calculation is worked below with real intermediate numbers. Use it when safety roi in safety and workforce is being compared against another safety and workforce project for the same budget.

The inputs for this scenario

  • Upfront safety program investment: 187,500 $ (raised for this scenario; the documented default is 75,000)
  • Annual savings from reduced incidents: 52,000 $ / yr (unchanged)
  • Annual program support cost: 8,000 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Payback = investment รท net annual savings) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.26 yr for safety roi payback period, the number this scenario is built around.
  • At this operating point the engine returns 44,000 $ / yr for net annual safety roi savings.
  • At this operating point the engine returns 187,500 $ for safety roi investment.
  • At this operating point the engine returns 32,500 $ for five-year net safety roi value.

How this compares with the baseline

  • Against the tool's baseline example, where upfront safety program investment sits at 75,000 $ and the headline result is 1.7 yr, this scenario comes in 150% above the baseline at 4.26 yr.
  • A figure at this level is achievable when upfront safety program investment is genuinely sustained, not just peaked for a shift. It assumes savings are steady year over year; real injury-cost avoidance is statistical and lumpy, so treat the payback as an expected value, not a guarantee.
