Security Awareness Training ROI Calculator

Estimate the financial return on investing in security awareness training by weighing program costs against the reduction in breach likelihood and associated costs.

Number of Employees

Training Cost per Employee ($/year)

Average Cost of a Security Breach ($)

Annual Breach Probability Before Training (%)

Annual Breach Probability After Training (%)

Program Duration (Years)

Annual Indirect Costs (lost productivity, admin, $)

#### Formulas Used

Annual Expected Loss (before/after) AEL = Breach Probability × Average Breach Cost

Annual Risk Reduction (Benefit) ARR = AELbefore − AELafter

Annual Total Program Cost ATC = (Employees × Cost per Employee) + Indirect Costs

Net Benefit (multi-year) Net Benefit = (ARR × Years) − (ATC × Years)

ROI ROI (%) = (Net Benefit / Total Cost) × 100

Payback Period Payback (years) = ATC / ARR

Break-Even Breach Cost Break-Even = ATC / (Pbefore − Pafter) The minimum breach cost at which the training investment is justified.

Breach Risk Reduction Risk Reduction (%) = ((Pbefore − Pafter) / Pbefore) × 100
