The implemented relation is Income replacement rate = average leave benefit ÷ prior covered earnings, evaluated from Average monthly prior covered earnings, Average monthly public leave benefit, Average employer monthly top-up, Average paid leave months, Annual leave benefit recipients to produce Average parental-leave income replacement. Caps, employer top-ups, taxes, eligibility, leave sharing and job protection require separate measures. The result depends on comparable definitions, units, populations and time periods.
