How do you calculate employer brand ROI?

Model the value against the cost. On the value side, estimate savings and gains: lower cost-per-hire, reduced agency and advertising spend, faster time-to-fill, improved retention and better quality of hire, each of which carries a real financial figure. On the cost side, total the investment in research, creative, technology and ongoing activation. ROI is the net gain relative to that spend, ideally tracked against a pre-programme baseline. Being disciplined earns credibility, because leaders discount vague claims but respect a defensible model. The pitfall is over-claiming precise causation, since many factors influence hiring; be transparent about assumptions and pair hard savings with directional perception data rather than pretending the whole shift is attributable to branding alone.
