Child data
Costs and income of each child, with one tab per child. For each expense, enter the cost in the Child total column. If Parent 1 pays part of it, enter that share in Parent 1's column: Parent 2's share is the rest.
Distribution of care
Holiday weeks
Weeks per year that the child spends with each parent during the school holidays.
The total for both parents must not exceed the holiday weeks in the phase calendar (PRO tab, Calendar).
The hours and nights of the typical week come from the Care plan grid.
Child's subsistence minimum
Basic amount
The child's subsistence minimum by age: CHF 400 under 10, CHF 600 from 10. Calculated automatically.
For an adult child (18–25) it is CHF 600; a different amount, for example if the child lives alone, is entered in the PRO tab.
If the child is cared for by paid third parties, a deduction for third-party care applies;
the result is the net basic cost.
Child's rent share
Share of housing attributed to the child at each parent's home, calculated automatically according to the method in the PRO tab (Housing).
Default method: a percentage of the actual rent of the parent the child lives with (percentages set by the administration, depending on the number of children: currently 20 % for 1 child, 15 % per child for 2, 13 % per child for 3 or more). Phases calculated before 30.10.2026 without a choice keep the Zurich table.
Basic health insurance
The child's monthly basic health insurance premium, without optional cover.
Health costs
Deductible, co-payment, dentist, speech therapy: monthly average not reimbursed.
Communication (mobile phone)
The child's subscription.
Paid third-party care
Nursery, after-school care, babysitter: monthly cost. It can be entered only if the Care plan grid contains
«Paid third party» periods; otherwise the tab asks you to fill in the grid first.
School / education costs
Materials, trips, school fees, tutoring.
Transport
The child's travel passes and regular transport.
Free items
Two lines with a description, for regular and documented expenses.
Additional needs
For adult children (18–25) only supplementary health insurance counts: pocket money, holidays and free additional items
are not included, because an adult child has no share of the surplus (BGE 147 III 265 cons. 7.2).
Supplementary health insurance + further costs
Premium for supplementary cover and other health costs. When the surplus is shared per head, it forms part of the child's extended needs.
Pocket money, holidays, free items
Monthly amounts; for holidays, divide the annual total by 12.
Child's income
For each amount, state which parent receives it: it is deducted from the child's needs at that parent's side.
Legal basis: Art. 285a CC.
Family allowance (FA)
Monthly amount for this child (federal minimum CHF 200, CHF 250 for children in education; cantons may provide more).
State which parent receives it: the calculation attributes it to that parent. In the result it appears next to the maintenance amount:
if the paying parent receives it, it is already included in the amount to be paid («of which …»).
Child's earnings
The child's wages, e.g. as an apprentice (Art. 323(2) CC).
OASI/DI pension / pension fund
Pensions for the child linked to a parent (e.g. child's or orphan's pension).
Child's investment income
Only the monthly income, not the assets.
As a rule, the child's income is deducted in full. A smaller share is set in the PRO tab, with a justification.
The professional finds a summary of the active choices at the bottom of the tab.
