Use New Brunswick's current Family Law Act framework
New Brunswick's Family Law Act and Child Support Guidelines Regulation replaced the former Family Services Act framework. The regulation adopts the federal Schedule I tables as amended from time to time, bringing the 2025 table amounts into the provincial calculation.
What this calculator estimates
Enter the paying parent's annual gross income before tax, province or territory of residence, and number of children. The calculator returns the monthly Schedule I table amount from the 2025 Federal Child Support Tables, effective October 1, 2025.
The table amount is a starting point. The correct support amount depends on the law that applies, reliable income information, the parenting arrangement, and the facts of the family.
A straightforward table example
For one child and annual income of $80,000, the 2025 New Brunswick table returns $699 per month. That figure addresses the base table amount. Shared or split parenting, special or extraordinary expenses, income above $150,000, an undue hardship claim, or a dispute over income changes the work required.
When annual recalculation may help
New Brunswick's Child Support Recalculation Service can update eligible income-based child support amounts each year using current income information. Its published eligibility rules include residence, the age of the order or agreement, and the kind of calculation contained in the existing terms.
Some matters fall outside the administrative service, including cases that require a judge to decide income, parenting, expenses, or another contested issue. Review the current eligibility list before submitting an application.
Keep the table result separate from the operative terms
The calculator result provides a reference point. The enforceable obligation comes from the order or agreement in force. Keep the signed terms, payment history, income disclosure, notices of assessment, and records for section 7 expenses together.
A later change in income leaves the existing amount in place until recalculation, agreement, or a court variation changes it. That distinction matters when arrears or enforcement questions arise.
Prepare the income and expense record
Start with the current order or agreement and the income material required by the Guidelines. Recent tax returns and notices of assessment often form the core record. Current pay information, corporate or self-employment documents, benefit statements, and evidence of another income source may also affect the annual income finding.
For section 7 expenses, collect invoices, receipts, subsidy or insurance information, and the tax treatment of the cost. The gross expense alone rarely tells the full story. The analysis may consider necessity, reasonableness, the child's needs, each parent's means, and the net cost after benefits, subsidies, and tax consequences.
When the calculation needs more information
The table result answers one question: the monthly Schedule I amount for the three inputs entered. A fuller support calculation brings in:
- shared parenting time or split parenting arrangements
- section 7 special or extraordinary expenses
- undue hardship claims
- income that is disputed, imputed, self-employment income, or income that varies
- income above $150,000
- retroactive support or arrears
- any order, agreement, variation, or enforcement decision
Use the estimate as a starting figure. The enforceable amount comes from the applicable order or agreement, interpreted alongside the Guidelines and the evidence for the family.
