Large Family Analysis
Raising 3 children involves 'economies of scale'. The multiplier applied to the base income accounts for shared household costs. While the total of $1,677 is higher than for one child, the per-child cost is lower, reflecting common shared resources.
The SSR and Low-Income Safeguards
A vital component of the 2026 system is the Self-Support Reserve (SSR), set at $2,394. If paying $1,677 would leave the payor with less than $2,394, the court may reduce the obligation for fairness.
