How Much Child Support Will I Pay on $100k?

If you make $100k annually, the amount of child support you need to pay typically ranges from $11,584 to $22,603 per year. Most payers are towards the bottom of this range and may be below it with at least a few nights of care per fortnight.

Here's how it breaks down in different scenarios:

• 1 young child (aged 0-12). You will pay around $11,584 per year if the other parent has full care.
• 3 teenage children (aged 13-17). The maximum payment is up to $22,603 per year if you have no visitation.
• 2 children (one young, one teen) with some care time. If you have some care (e.g., 2 nights per fortnight) and the other parent earns $56,000, you pay approximately $12,134 annually.

Key Factors Affecting How Much You Pay

How much child support you will pay if you make $100k depends heavily on the number of children involved and your nights of care per fortnight. The other parent's income also has a bearing, especially if care is shared quite evenly.

Number of children

The number of children you support significantly impacts the amount of child support you pay. More children generally lead to higher payments. However, even with just one young child, you may still be required to pay more than half the maximum possible amount.

For example, a parent with one child under 13 and no visitation might pay $11,584 annually, which is more than half of the maximum amount payable for three teenagers.

Nights of care per fortnight

The number of nights you care for your child each fortnight also affects how much child support you pay. As the amount of care approaches 50:50, your payments decrease, potentially down to zero if you have equal care. However, even with shared care, differing incomes between parents can still result in significant payments.

For instance, if you have some care (like 2 nights per fortnight), the amount you pay will be less than if you had no visitation, but there may still be a considerable payment depending on the income difference.

Other parent's income

The income of the other parent affects child support payments. Generally, the less the other parent earns, the more you pay. However, this effect is modest if you have little or no overnight care. By contrast, when care is evenly shared, the parent with the higher income pays the other.
