British Columbia Child Support Calculator

Start with the right service and court

Family Justice Centres and Justice Access Centres offer information, needs assessment, mediation, and referrals in person or virtually. A Family Justice Counsellor can help identify the issues, explain options, and connect a family with appropriate services.

Both the Provincial Court of British Columbia and the Supreme Court of British Columbia address child support under provincial family law. Supreme Court also hears divorce and family-property claims. A case that combines support with a divorce or property claim will often proceed there, while many support-only applications proceed in Provincial Court.

Legal Aid BC may be another route to advice or assistance, depending on the issue and eligibility.

The narrow answer from the table

For a paying parent who lives in British Columbia, annual income of $80,000 and one child produces a 2025 table amount of $758 per month. The figure supplies the base amount for a straightforward majority-parenting-time calculation.

A fuller calculation may add section 7 expenses or address shared or split parenting, hardship, disputed income, retroactive support, or arrears. Each issue requires its own evidence. For example, special expenses call for invoices, proof of subsidies or reimbursements, and both parents' incomes; disputed self-employment income may call for business financial statements and an explanation of personal expenses paid by the business.

Prepare the record that supports the number

Start with the last three tax returns and notices of assessment or reassessment, current proof of earnings, and the existing order or agreement. Add documents that explain a material change, such as a new job, a layoff, fluctuating contract income, corporate distributions, or a revised parenting schedule.

Where parents share parenting time, prepare a calendar that shows the actual schedule over the year and a list of the child-related costs carried in each home. Section 9 uses both table amounts and also considers the increased costs of shared parenting and the circumstances of each parent and child.

If the amount is already in an order

The BC Family Maintenance Agency processes payments, records the account, collects arrears and specified special expenses, and enforces enrolled support orders and agreements. Its work follows the amount stated in the enforceable document.

A recalculation service, a new agreement, or a court application supplies the path to an updated amount after income changes. Once the new terms are enforceable and provided to BCFMA, the agency administers the revised obligation. B.C.'s family-justice resources can help identify which route fits the order and the family.
