A read-only helper that estimates child support under the Québec model (Ministère de la Justice du Québec), using the official 2026 base-contribution table (Regulation C-25.01, r. 12). From the figures you provide - each parent's annual income, optional union and professional dues, the number of children, the share of custody time, and any net special expenses (child care, post-secondary, medical) - it computes each parent's disposable income, the base parental contribution from the combined income, the pro-rata split between the parents, the custody-mode adjustment (sole custody, extended access, or shared custody), and applies the cap of 50% of the debtor parent's disposable income. It can also compute a single parent's disposable income and explain each step of the model with links to the official sources. It is deterministic and shows its calculation. It is an estimate and general information, not legal advice or an official amount: the real amount is set by the court or by SARPA, and specific circumstances may change it. It covers only the Québec model for the 2026 year and does not compute income tax.
