Colorado Alimony & Spousal
Support Calculator

Colorado uses a statutory formula to calculate maintenance, providing a more predictable framework for divorcing spouses than pure judicial discretion. Under C.R.S.

§ 14-10-114, the court applies a mathematical formula based on each spouse's gross income to determine both the amount and duration of alimony payments. While the formula provides a presumptive guideline, Colorado courts retain the ability to deviate from it when circumstances warrant.

The formula-based approach in Colorado was designed to reduce divorce litigation costs and increase consistency across family law cases. The state's formula considers formula: 40% of higher income minus 50% of lower income, capped at 40% of combined income; duration based on marriage length.

However, the formula is just a starting point — judges may adjust the final maintenance award based on the specific facts of each case, including the standard of living during the marriage, the age and health of both parties, and the distribution of marital property.

Use our Colorado alimony calculator above to estimate your maintenance obligation or entitlement based on the formula. Whether you are the paying spouse or the receiving spouse, the formula output gives you a realistic range to negotiate from before engaging with an attorney.

Family law attorneys in Denver and across Colorado can explain how local courts apply the formula in practice and whether your facts support a deviation.

Colorado recognizes several types of maintenance: temporary, short-term, long-term, contractual. Each serves a different purpose and applies under different divorce circumstances.

The type of alimony awarded depends on the length of the marriage, the financial circumstances of both spouses, and the specific needs demonstrated by the requesting party.

Temporary alimony (also called pendente lite maintenance) is awarded during the divorce proceedings to maintain the financial status quo while the case is pending. This type of support ensures that the lower-earning spouse can cover living expenses — including housing, utilities, and basic needs — until Colorado courts issue a final maintenance order.

Temporary support automatically terminates when the final divorce decree is entered.

Colorado distinguishes between contractual maintenance (agreed upon by the spouses in a divorce settlement) and court-ordered maintenance. Contractual alimony is governed by the terms of the divorce agreement and is generally non-modifiable unless the agreement itself provides for modification.

Court-ordered maintenance is subject to modification based on a material change in circumstances.

Colorado uses a statutory formula to determine presumptive maintenance amounts based on each spouse's gross income. The formula works as follows: formula: 40% of higher income minus 50% of lower income, capped at 40% of combined income; duration based on marriage length.

This mathematical approach provides a starting point that both parties and their family law attorneys can use to estimate likely alimony obligations before going to court. For example, if the higher earner brings home $8,000/month and the lower earner makes $3,000/month, the formula produces a specific presumptive figure that the court can then adjust based on the circumstances of the case.

The formula calculates a presumptive amount, but Colorado courts are not strictly bound by it. Judges may deviate from the formula result if the presumptive amount would be unjust or inappropriate given the specific circumstances of the divorce.

Common reasons for deviation include significant disparity in assets, one spouse's contribution as a homemaker, family violence, or the tax consequences of the maintenance award.

Duration of alimony is also guided by statutory formulas in Colorado, typically based on a percentage of the length of the marriage. For shorter marriages, maintenance duration in many jurisdictions runs **15–30%** of the marriage length as a general benchmark — though Colorado courts retain discretion to deviate based on the specific circumstances of each case.

For marriages exceeding 20 years, courts may award indefinite alimony. Use our Colorado alimony calculator to estimate both the amount and duration based on your specific monthly gross income figures and marriage length.

Colorado uses advisory maintenance guidelines under C.R.S. § 14-10-114 to calculate spousal maintenance amounts and duration.

The advisory formula calculates the maintenance amount as 40% of the higher-earning spouse's monthly adjusted gross income minus 50% of the lower-earning spouse's monthly adjusted gross income, with a cap at 40% of combined adjusted gross income. This advisory formula applies when the combined adjusted gross income of both spouses does not exceed a statutory threshold.

Duration of maintenance in Colorado is based on the length of the marriage. For marriages of 3 years, maintenance may last 11 months.

For marriages of 20 years, it may last up to 10 years. For marriages exceeding 20 years, the court may award indefinite maintenance.

Colorado courts may deviate from the advisory guidelines if applying them would be unfair or inequitable based on the specific facts of the divorce case. Family law attorneys in Colorado Springs, Denver, and across the state can help estimate your likely maintenance obligation.

The length of the marriage is the single most important factor in determining how long alimony lasts in Colorado. Short-term marriages (generally under 10 years) rarely result in long-term alimony awards.

When maintenance is granted for a short marriage, it is typically rehabilitative and limited to 2–5 years — enough time for the receiving spouse to become self-supporting through education or training.

For moderate-length marriages (10–20 years), maintenance duration in Colorado is often set as a percentage of the marriage length. As a general benchmark used by many courts, that figure falls in the range of **30–50%** of the marriage — though Colorado judges have discretion to award more or less based on the specific facts.

A 15-year marriage, for example, might result in a alimony award lasting 5–7 years. The specific duration depends on factors like the age of the receiving spouse, their earning capacity, and whether they sacrificed career opportunities during the marriage.

Long-term marriages (20+ years) may qualify for indefinite or permanent maintenance in Colorado, particularly when the receiving spouse is older, has limited earning capacity, or made significant career sacrifices to support the family. Even permanent alimony is subject to review and modification if circumstances change substantially — for example, if the paying spouse retires or the receiving spouse begins cohabiting with a new partner.

Under the Tax Cuts and Jobs Act (TCJA) of 2017, alimony payments pursuant to divorce agreements executed after December 31, 2018 are no longer tax-deductible for the paying spouse or taxable income for the receiving spouse. This was a major change from prior law, where the payor could deduct maintenance payments and the recipient reported them as gross income.

If your divorce was finalized before 2019 and you have not modified the agreement, the old tax rules may still apply to your payments. See IRS Publication 504 (Divorced or Separated Individuals) for the federal tax treatment that applies regardless of state.

Spousal maintenance orders in Colorado can be modified if either spouse demonstrates a material change in circumstances. Common grounds for modification include significant changes in income (job loss, disability, retirement, or substantial raise), changes in the receiving spouse's financial needs, or the receiving spouse becoming self-supporting sooner than expected.

The party seeking modification bears the burden of proving the changed circumstances to Colorado courts.

Spousal maintenance in Colorado typically terminates automatically upon the remarriage of the receiving spouse or the death of either party. Colorado also allows termination or reduction of alimony if the receiving spouse enters into a supportive cohabitation arrangement — essentially living with a new partner in a marriage-like relationship.

Consult a family law attorney if any of these circumstances apply to your situation.

In Colorado, child support and alimony are calculated separately but interact with each other. Most Colorado courts calculate child support first using the state's child support guidelines — use the Colorado Child Support Estimator to see how that figure is determined — then determine maintenance based on the remaining gross income available to each spouse.

This sequencing matters because child support obligations reduce the paying spouse's available income for alimony purposes. Some states impose a combined cap, limiting total support payments (child support plus maintenance) to a percentage of the payor's gross income, often **40–50%**.

Unlike child support, which follows formulaic guidelines tied to income changes, alimony modification generally requires a more substantial showing of changed circumstances. Child support generally takes priority in Colorado — if the paying spouse's income drops, courts typically preserve child support obligations before adjusting maintenance obligations.

Child support also ends when the child reaches the age of majority, which may trigger a review of alimony if the paying spouse's financial picture changes significantly during the divorce process.

Alimony is one component of the overall divorce financial picture. The Colorado Divorce Cost Estimator projects total attorney fees and filing costs for your case.

For divorces with children, the Colorado Child Support Estimator calculates guideline support amounts using Colorado's income model. And for marital property allocation, the Colorado Property Division Calculator covers Colorado's equitable distribution or community property rules.
