SMM costs are measured according to the Chigueda Index which measures return on investment in cost per smilemeter (SMM).
The Chiqueda Index is a human happiness measure that calculates hapiness produced in relation to the financial investment required to produce the happiness.
Average length of a smile (SL) x nr of beneficiaries (B) x (seconds of smiles (SS) -
baseline smiles (BS) = annual happiness distance (AHD)
total income of organisation ($) / (AHD/100) = cost per SMM

Where AHD = (SL x B x S (SS-BS))/100000
Thus SMM = ((SL x B x S)*1000) / $

For GDM:
SL = 2,9 cm of average smile
B = 350 number of beneficiaries
BS* = 65520
SS* = 109200
S = 43680
AHD = 443,352 km
Annual Income = $ 60000
SMM 0,135 cost in Euro to produce one meter of smiles
