Copayment Structure

Three FPL tiers with rates varying by care type (FT/PT) and child count (1 vs 2+):

FPL Tier	1 Child FT	1 Child PT	2 Children FT	2 Children PT	1 FT + 1 PT
≤100% FPL	waived	waived	waived	waived	waived
101-200% FPL	4%	2%	6%	3%	5%
201%+ FPL	5%	2.5%	7%	3.5%	6%

• 3rd+ child: $0 additional copay — N.J.A.C. 10:15-9.1
• Cap: 5% of gross income — CCDF State Plan Section 3.1
• Formula: monthly_copay = annual_gross_income * copay_rate / 12

Implementation uses additive first-child + second-child rate parameters by FPL bracket. Source: CC-236

Provider Rate Schedule

4 provider types x 8 age groups x 2 care types x up to 4 quality tiers:

Provider Type	Quality Tiers	Age Groups	Source
Licensed Child Care Center	Base, 3-Star, 4-Star, 5-Star	All 8 (school-age: base only)	CC-230 p.1
Registered Family Home	Base, 3-Star, 4-Star, 5-Star	All 8 (school-age: base only)	CC-230 p.2
Approved Home (FFN/In-Home)	Base only	All 8	CC-230 p.3
ACA Summer Youth Camp	Base only	School-age only (2 groups)	CC-230 p.4

Age groups: Infant (0-17 mo), Toddler (18-29 mo), Preschool (30 mo-5 yr), School-Age (5-13 yr), plus special needs variants for each.

Weekly rates stored in parameters; benefit formula: min(expenses - copay, max_reimbursement) where max reimbursement is the sum of per-child weekly rates converted to monthly.

Benefit Calculation

For each eligible child:
  max_weekly_rate = lookup(provider_type, quality_rating, age_group, time_category)

Total max_monthly = sum(max_weekly_rate) * 52 / 12

monthly_copay = min(annual_income * copay_rate / 12, annual_income * 5% / 12)

benefit = max(0, min(pre_subsidy_childcare_expenses - monthly_copay, total_max_monthly))
