Embed the Child & Spousal Support Calculator

One calculator, three modes — child support, spousal support, or both. Free for any law firm, legal aid clinic, or family services organization to embed.

What's included

Child support. Federal Child Support Guidelines, Schedule I (all provinces except Quebec) — sole and shared custody, Section 7 apportionment by income proportion.
All SSAG formulas. Without-Child-Support, plus With-Child-Support for Basic, Shared, Split, and Custodial Payor arrangements.
Full tax engine. Federal and provincial (BC, AB) marginal tax, CPP, EI, CCB, GST credit — calculated on current (2026) rates.
Iterative INDI calculation. Converges each 40/43/46% target to within $1, recalculating taxes as spousal support changes.
Imputation & Section 7. Per-spouse income imputation; proportional apportionment of special expenses.
Duration rules. Rule of 65, 20-year indefinite, and length-of-marriage ranges from cohabitation and separation dates.
Toggle between modes. Users switch between child support, spousal support, and both — without losing their entered data.
Mobile-responsive. Works cleanly on any screen size.
