Conventional system
Cascade system
Total conventional system: €271
Total cascade system: €145
Four ingredients, one automatic calculation.
A collective goal
The group sets the total amount to cover: shared expenses, group purchases, operating budget.
A distribution rule
Percentage of income, family quotient, tiered scale, or free contribution with a solidarity floor: each group chooses its own rule.
An automatic calculation
Cascade applies the rule to each member and recalculates their contribution as soon as a profile or the goal changes.
An adjustment at any time
The goal or the rule can change along the way; contributions readjust without any re-entry.
Each group chooses its own formula.
Percentage of income
Everyone contributes in proportion to what they declare.
Family quotient
The amount takes household composition into account, as with a daycare center.
Tiered scale
Tiers defined in advance, from the most supportive to the most comfortable.
Free contribution with a solidarity floor
Everyone gives what they can, above a guaranteed minimum for the group.
The same mechanism, very different uses.
