How Child Support is Calculated Worldwide

While each country has its own specific guidelines, most child support calculations consider these universal factors:

1

Parental Income

Most jurisdictions consider the gross income of both parents. Some countries cap the income considered, while others use a percentage model. Self-employment income, bonuses, and investment income are typically included.

2

Number of Children

Support amounts increase with more children, but not proportionally. Many systems use a decreasing percentage per additional child. The age of children may also factor into some calculations.

3

Custody Arrangements

The time each parent spends with the children significantly impacts calculations. Most systems reduce support obligations for shared custody arrangements, with specific formulas for different time divisions.

4

Additional Expenses

Healthcare, childcare, education, and special needs expenses are often added to base calculations. Some jurisdictions split these expenses proportionally to income, while others assign them to the parent incurring them.
