Does Changing Parenting Time Change Child Support in Colorado?

Changing the parenting schedule can change child support in Colorado, but it does not happen on its own. Overnights are a direct input in the guideline calculation, so a schedule change can move the number, though whether it moves far enough to matter depends on the rest of the calculation. Someone still has to ask the court for a new order before modifying child support in Colorado takes effect.

There is a threshold to clear, too. The recalculated amount generally needs to differ from the current order by at least ten percent before the change counts as substantial and continuing.

How Overnights Factor Into the Calculation

Colorado’s guideline was revised by House Bill 25-1159, with the core calculation provisions taking effect March 1, 2026. ^[1] The way overnights are credited changed meaningfully.

Each parent’s overnight total maps to a parenting time credit percentage in a statutory table. The parenting time credit is the total basic child support obligation multiplied by that parent’s credit percentage, and the resulting shared parenting adjustment is deducted in the worksheet. ^[2]

Credit begins with the first overnight and increases as overnights increase. That is the mechanism, and it is more specific than a flat percentage reduction applied to what a parent would otherwise owe.

The credit is also not proportional to time. A parent with roughly a quarter of the overnights receives a credit smaller than a quarter, because the majority-time household still carries fixed costs that do not shrink when the child is away.

When a Schedule Change Matters

Historical context: the pre-March 1, 2026 framework

This section describes the rule that applied before March 1, 2026. It is background only and does not govern orders calculated under the current guideline.

Under that older framework, everything hinged on whether a parent reached 93 overnights. Below that line a parent received no credit at all, and at that line the calculation shifted sharply, which is why families sometimes litigated hard over a single night.

What applies now

That cliff is gone for orders calculated under the current guideline. Because credit now scales from the first overnight, a moderate schedule change is more likely to move the number than it once was, and an extra night or two is less likely to swing it dramatically.

What matters is whether the change is substantial and continuing, which is a fact-specific question rather than a bright-line test. A short-term summer arrangement will not always be treated the same way as a permanently revised parenting time schedule.

The Threshold to Modify Support

Colorado permits modification of child support only on a showing of changed circumstances that are substantial and continuing. ^[3]

The statute defines the floor. If applying the guideline to current circumstances produces less than a ten percent change in the monthly amount, that is deemed not to be a substantial and continuing change. ^[4] Colorado appellate decisions have treated that ten percent figure as a rebuttable presumption rather than a conclusive one.

A schedule change alone does not guarantee you clear the threshold. Whether the overnight shift produces a ten percent swing depends on both parents’ incomes and the other adjustments in the worksheet.

How to Request a Modification

These are practical workflow steps rather than statutory requirements. The legal standard is the one described above.

1. Run the guideline using the current schedule and current income figures for both parents
2. Compare the result to the existing order to see whether the difference reaches ten percent
3. Gather documentation of the new schedule and any income changes since the last order
4. File a motion to modify with the court that entered the order

Timing matters more than most parents expect. As a general rule, modification reaches installments accruing after the motion is filed, so support that came due before filing stays owed at the original amount. The statute contains limited exceptions, so this is the default rather than an absolute. ^[5]

Common Mistakes Parents Make

• Assuming support adjusts automatically when the schedule changes, when it does not
• Agreeing informally to reduce payments without a modified court order, which leaves arrears accruing on paper
• Waiting months after the schedule changed before filing, giving up the retroactive window back to the filing date
• Relying on an online calculator still running the pre-2026 worksheets and the old overnight threshold

Frequently Asked Questions

Does parenting time affect child support in Colorado?

Yes. The number of overnights each parent has is a direct input in the guideline calculation. Under the guideline changes effective March 1, 2026, parenting time credit begins with the first overnight and scales gradually rather than switching on at a single threshold.

How many overnights changes child support in Colorado?

There is no longer a single magic number. The former 93-overnight threshold was eliminated for orders calculated under the current guideline, and credit is now set by a statutory parenting time table that increases as overnights increase.

Can child support change if the schedule changes?

It can, but a schedule change does not adjust support automatically. Someone has to file a motion to modify, and the recalculated amount generally needs to differ from the current order by at least ten percent.

What is a substantial and continuing change for child support?

Colorado requires changed circumstances that are substantial and continuing to modify support. Applying the guideline to current circumstances must produce at least a ten percent change in the monthly amount, or the change is deemed not substantial and continuing.

How Johnson Law Group Can Help

The practical question is not whether your schedule changed. It is whether the recalculated guideline number moves far enough to justify filing, and that takes running the actual figures before you spend anything on a motion.

The attorneys on our team at Johnson Law Group can give you a clear read on where your case lands under the current guideline and whether a modification is worth pursuing now or later.

Ask whether your schedule change supports a modification, at one of our office locations across Colorado or in a virtual, no-pressure consultation.
