Colorado Family Law Tools

We publish our method because a number you cannot check is a number you should not trust. The maintenance calculator implements the advisory guidelines in C.R.S. 14-10-114(3): the income formula with its 80 and 75 percent adjustments, the duration table, and the $240,000 combined income limit above which the formula gives way to the court's judgment. The child support calculator implements C.R.S. 14-10-115 as rewritten by HB 25-1159, effective March 1, 2026, with both statutory tables extracted directly from the enacted bill text rather than copied from secondary sources.

Both engines run against automated test suites, 96 assertions combined, that check computed results against the statute's own published figures, including the self-support reserve, which the law re-derives from the state minimum wage every January 1. We re-verify both calculators against the statutes each year when those figures reset, and each tool states the date of its last statutory review. When the law moves, the tools move, and the worked examples across this site are generated by these same engines, so there is exactly one place the math lives.

Statutory review current as of August 2026. Estimates are planning tools; the court's official worksheets govern in every case. See the engines at work in our attorneys' worked examples of the 2026 law.
