Large Family Analysis
Raising 4 children involves 'economies of scale'. The multiplier applied to the base income accounts for shared household costs. While the total of $1,132 is higher than for one child, the per-child cost is lower, reflecting common shared resources.
The SSR and Low-Income Safeguards
The Self-Support Reserve (SSR) is a legal shield. With the 2026 SSR at $2,394, any support order based on $2,500 is cross-referenced against this floor. If $1,132 is too high, the court will adjust it.

This reflects shared costs like housing and utilities that don't scale linearly with each additional child.
