The net fiscal cost after accounting for increase tax revenue and social protection savings was €72 MM.
This was then offset to get to a positive net social gain by €80 MM in "wellbeing gains", as measured by a single survey question called the WELLBY test:
> “Overall, how satisfied are you with your life nowadays, where 0 is "not at all satisfied" and 10 is "completely satisfied"?
The €80 MM in "wellbeing gains", which is the sole decider of whether this pilot was a net positive or a huge net negative to society, is because on average, the 2,000 pilot scheme participants had a very approximate 0.7–1.1 increase in score when asked the above question during the pilot as compared to before the pilot. Each 1 point was deemed to be worth €15,340.
