50/50 custody: who pays for what?
Equal parenting time doesn't mean costs split themselves evenly. Here's who typically pays what under a 50/50 custody schedule — what each home covers alone, what gets shared, and how support still fits in.

A 50/50 custody schedule splits time evenly. It does not automatically split money evenly, and assuming it does is where a lot of equal-time co-parents get stuck. Here is how costs usually fall when the children spend roughly half their time in each home.
Equal time does not always mean equal money
Even with a 50/50 schedule, one parent often still pays child support if there is a meaningful income gap, because support is about keeping the children's standard of living steady across both homes. The schedule and the money are two separate questions. Sort the money question on its own, using the income gap as your guide. There is more on this in child support versus shared expenses.
What each parent typically covers alone
In an equal-time arrangement, each home runs itself. The parent whose time it is usually covers:
- Food and meals during their parenting days.
- Their own housing, utilities, and transport.
- Everyday items and small treats at their home.
- A basic set of clothes and essentials kept at each house.
What 50/50 co-parents usually share
The children's larger and ongoing costs do not belong to one home, so they get split — commonly 50/50 to match the time, or by income if the gap is wide:
- Medical, dental, and therapy not covered by insurance.
- Childcare needed for work.
- School fees, supplies, uniforms, and trips.
- Extracurricular activities and their equipment.
- Big agreed purchases like a phone or a school laptop.
Keep two homes from buying everything twice
Equal time means two of some things — two beds, two sets of basics. That is normal, and each home covers its own. The waste comes from duplicate big purchases nobody coordinated. A quick check with your co-parent before buying anything substantial keeps you from each buying a winter coat in the same week.
Write down the split for shared costs
Because the schedule is even, it is tempting to leave the money informal. Don't. Decide the ratio for shared costs, the categories it covers, and an approval threshold for big items, then keep a single shared record so the even split stays even in practice. KidShare lets you set 50/50 as the default and override it per expense when something should be split differently.
This is general information, not legal advice. How support and shared costs work under a 50/50 schedule depends on your jurisdiction and any court order.
