The figures were not for suicide specifically but from their source for generating the cost of a statistical life.
I'm simply saying reducing mortality 0.001% doesn't equal 10 million dollars saved per 100,000 people as they somewhat implied. It's that society as a whole is perhaps willing to spend $10 million to reduce mortality 0.001%.
What made you come up with that nonsensical figure? Suicide is the leading cause of death in males under 45 in the UK. [0] And here's another tidbit [1]:
> Eliminating suicide as a cause of death would have increased life expectancy at birth by 1.92 years for males and 1.36 years for females from 2011 to 2015 [in the US].
We can debate whether and how much reducing mortality helps society, but please don't pretend that suicide is in minor in the grand scheme of things.
