How to Use the SA Maintenance Calculator
Determine Net Incomes: Enter the monthly Net Income (after tax) for both parents. This is used to calculate the "Pro-Rata" split (if you earn double, you typically pay double the share).
List Shared Expenses: Enter the total household costs (Rent, Water, Groceries). The calculator uses the "Acutt vs Acutt" rule (2 parts per adult, 1 part per child) to fairly calculate how much of the rent/groceries is attributable to the child.
List Direct Expenses: Enter costs that are 100% for the child, such as school fees and their specific portion of Medical Aid.
Frequently Asked Questions
Is there a fixed percentage (e.g., 30%)?▼
No. Unlike some countries, South African law (Maintenance Act) does not use a fixed percentage. It is based purely on the **Reasonable Needs of the Child** shared between parents according to their **respective means** (Pro-Rata).
How do I apply for maintenance?▼
You must visit your local Magistrate's Court and fill out **Form J101**. You will need to bring proof of your income (payslips, bank statements) and a breakdown of the child's expenses (receipts).
What is the Acutt v Acutt rule?▼
It is a legal precedent used to split general household costs (like rent or groceries). It assumes that an adult consumes "2 parts" and a child consumes "1 part". For example, in a house with 1 Adult and 1 Child, the child is responsible for 1/3 (33%) of the rent.
I am unemployed, do I still pay?▼
You have a legal duty to support your child. If you have no income but own assets (car, house), the court may order these to be sold. If you have absolutely no means, the duty may temporarily fall on the child's grandparents.
