Colorado Alimony Calculator 2026

Colorado Alimony Formula & Factors

Colorado follows a Guideline approach to spousal support (also called alimony or spousal maintenance). 40% payor − 50% payee; marriages 3+yrs. This means the court looks at the financial picture of both spouses and decides on a fair amount based on statutory factors.

Key factors Colorado courts consider include: the length of the marriage, each spouse's income and earning capacity, the standard of living established during the marriage, each spouse's age and health, contributions to the other spouse's career or education, and any misconduct (fault) where relevant under state law.

This calculator estimates alimony using a simplified formula: monthly alimony ≈ max(0, payor income × 40% − payee income × 50%). For Guideline states, this approximates the formula. For Discretionary states, it provides a rough estimate — the actual amount may differ significantly based on the judge's assessment of all factors.

Because alimony in Colorado is guideline, there is no guaranteed outcome. Two similar cases with the same incomes and marriage length can result in very different alimony orders depending on the judge and the specific facts. Always work with a licensed Colorado family law attorney before making financial decisions based on any estimate.

Alimony Calculator Denver — What the 2nd Judicial District Actually Uses

Denver County sits in Colorado's 2nd Judicial District, and like every Colorado district it applies the same statewide advisory guideline in C.R.S. 14-10-114 — there is no separate Denver formula. What differs between Denver, Jefferson, Arapahoe, Boulder and El Paso counties is judicial practice around the edges: how aggressively income is imputed to an underemployed spouse, how much weight the marital standard of living carries, and how readily a judge departs from the advisory number.

Three things decide whether the number above will survive a Denver hearing. First, the $240,000 combined-income ceiling — the guideline is written for couples at or below it, and Denver's higher professional salaries push many cases past it, at which point the judge builds the award from the statutory factors instead. Second, the three-year marriage minimum; below it the guideline simply does not apply. Third, the statute's 40%-of-combined-income cap, which trims the award in cases where one spouse earns far more than the other. The Colorado Judicial Branch publishes the official Spousal/Partner Maintenance Advisement worksheet that Denver courts hand to self-represented parties — bring your calculator figure and that worksheet to mediation and you will be negotiating inside the same bounded range as opposing counsel.

Maintenance is also separate from child support. If minor children are involved, the Colorado child support worksheet runs first and the maintenance figure feeds into it, so an estimate that ignores child support will overstate what actually lands in either household. Updated 2026-07-30.

Colorado Alimony Duration Rules

How long alimony lasts in Colorado depends primarily on the length of the marriage. The general rule: 31% of marriage length.

Short marriages (under 5 years) rarely result in long-term alimony. Courts in Colorado typically award rehabilitative or transitional support designed to help the lower-earning spouse become self-sufficient — for example, to complete a degree or re-enter the workforce. For longer marriages (15+ years), periodic or open-ended alimony is more common, especially if one spouse was out of the workforce for child-rearing.

Alimony in Colorado typically ends automatically when: the recipient spouse remarries; either spouse dies; a court order terminates it; or the marriage was short enough that a fixed end date was set. Cohabitation with a new romantic partner may also trigger a modification or termination petition, even without remarriage.

In cases where one spouse sacrificed career advancement for the family — for example, leaving work to raise children — Colorado courts may award longer-duration or permanent alimony to compensate for the economic disparity created during the marriage.

Modifying Colorado Alimony

Alimony orders in Colorado are not permanent and can be modified or terminated if circumstances change substantially. Common grounds for modification include: a significant increase or decrease in either party's income; the recipient's remarriage or cohabitation; a change in the needs of either party; or a change in employment status.

To modify alimony in Colorado, the requesting party must file a motion with the family court that issued the original order. The court will review current financial circumstances of both parties and decide whether a modification is warranted. Simply losing a job or getting a raise is usually not enough on its own — the change must be substantial, ongoing, and not self-induced.

If you are the payor and lose your job, you should file for modification promptly. Courts in Colorado generally cannot retroactively reduce alimony for periods before the motion was filed. Delaying a modification request can result in mounting arrears that are very difficult to discharge.
