Free tool · Parenting time · Form 14 line 11
This Missouri parenting time calculator counts every overnight in a parenting schedule across a full year, with holidays, spring break and summer included.
Two numbers in a Missouri custody case turn on the overnight count. The first is how close a schedule comes to the equal or approximately equal parenting time that section 452.375.2 presumes is in a child’s best interests. The second is the overnight adjustment on line 11 of Form 14, the child support worksheet. Bardol Law Firm built this calculator so parents can see what a proposed schedule actually adds up to before they agree to it. Nothing you enter leaves your browser.
Pick one of 12 common schedules, follow Week One and Week Two from your parenting plan, or copy your plan’s two-week chart.
Set the dates and who has each one. Holidays override the regular schedule.
Add Parent B’s summer weeks, in one block or alternating.
This calculator is for informational and educational purposes only. It gives an estimate for planning, and a court counts the overnights in your actual order.
Count Your Overnights
Parent A is the parent with the children most of the time. Parent B is the other parent, usually the one who pays support on Form 14. Everything runs in your browser, and nothing you enter is saved or sent anywhere.
The schedule that applies during the school year when no holiday is in effect.
Copy the Week One and Week Two rows from your parenting plan. Tap a night to switch it between Parent A and Parent B. Mark whoever has the children overnight. If your plan lists exchanges, such as “Friday 5:00 p.m. Father receives children,” the night belongs to the parent who has the children after the day’s last exchange.
Week One and Week Two follow the dates in Missouri parenting plan forms. The week starting with the first Sunday of January is Week One, and weeks alternate from there. The count restarts each January, so when December 31 is a Sunday, Week One repeats.
Dates default to common placements for the year you picked. Change them to match your parenting plan and your school calendar. Holidays override the regular schedule.
During Parent B’s summer weeks, Parent B has every night. During alternating weeks, the regular schedule applies in Parent A’s weeks.
St. Louis County’s parenting plan form, unless the parents choose otherwise, alternates weeks all summer from the first Friday after school ends. To match it, choose alternating weeks, set the start to that Friday, and give Parent B half of the summer’s weeks.

The line 11 percentages come from the Form 14 directions as revised January 1, 2026. A court counts overnights that are awarded and actually exercised, and the credit generally isn’t allowed unless the receiving parent’s adjusted income is above a floor that depends on the number of children, with two narrow exceptions. Week One and Week Two follow the dates in Missouri parenting plan forms, including St. Louis County’s Form CCFC180. In Bennett v. Bennett, 732 S.W.3d 495, counting the holidays and vacations in the plan moved a father from the 10 percent band to 15 percent. This tool gives an estimate for planning and is not legal advice. Using it does not create an attorney-client relationship.

Why the Overnight Count Matters
Since August 28, 2023, section 452.375.2 has presumed that equal or approximately equal parenting time is in a child’s best interests. Parents now negotiate from that starting point, and the difference between proposals is usually measured in overnights. Our equal parenting time checker explains how the presumption applies to your situation.
The same count drives child support. Form 14 gives the parent who pays support a credit on line 11 for a share of what that parent spends during overnight visitation or custody. The credit is a percentage of the basic support amount on line 5, and the percentage depends on the number of overnights per year.
The Form 14 Overnight Table
These are the line 11 percentages in the Form 14 directions as revised January 1, 2026. The percentage is applied to the basic child support amount on line 5.
The income floor. The line 11 adjustment generally is not allowed unless the adjusted monthly gross income of the parent receiving support is above $1,750 for one child, $2,200 for two, $2,550 for three, $2,850 for four, $3,100 for five or $3,600 for six. The directions list two exceptions. Our Missouri child support calculator checks the floor for you.
Holidays, Breaks and Summer Change the Number
Parenting plans usually put holidays, school breaks and summer on their own schedule, and that schedule overrides the regular one. Those nights are easy to leave out when parents count only the weekly rotation.
The trial court used a Form 14 with a 10 percent line 11 credit, which fits 92 to 109 overnights a year. The father had two overnights a week plus holidays, spring break and a vacation week. The Western District counted the plan out on calendars across several years, found 116 to 119 overnights, applied 15 percent and lowered support from $1,954 to $1,766 a month.
The court also found the count shifted depending on which parent had the first weekend of the year, which is why this calculator asks which weekends are Parent B’s, either by a start date or by Week One and Week Two of the parenting plan.
A father’s request to lower support under the 20 percent rule failed because his Form 14 still claimed the overnight credit for time he was not actually using. Count the nights that really happen, not only the nights the order awards.

How Common Schedules Count Out
These are the counts for the regular schedule alone in calendar year 2027, before holidays, breaks and summer are added. Every schedule here is one of the calculator’s presets, and the calculator gives the exact figure for your year and plan.
A few nights can change the credit. At 136 overnights the line 11 adjustment is 23 percent, and at 137 it is 25 percent, so count holidays and summer before you settle on a number.
Young children are a different case. Some plans for infants and toddlers use shorter, more frequent visits, which our page on the young child plan covers.
Tips for an Accurate Count
Enter the schedule the way the parenting plan or judgment states it, including the exact day and time each weekend begins and ends.
Winter break, spring break and Thanksgiving dates come from the school calendar. Change the default dates to match it.
Holidays often alternate between even and odd years. Count both years if the result matters, since the totals can differ.
Form 14 counts overnights that are awarded and exercised. If the schedule is not being followed, the actual count is the one that matters.
A calendar of the nights actually spent with each parent is useful evidence in a custody or support case.
Our parenting plan page explains what a Missouri plan has to address, and our child custody page covers the rest of the process.

Questions About the Missouri Parenting Time Calculator
What does a parenting time calculator do?
It counts the overnights each parent has in a year under a specific schedule. This one applies the regular schedule, then holidays, breaks and summer, and shows every night on a calendar along with the Form 14 line 11 percentage.
How many overnights is 50/50 in Missouri?
A year has 365 or 366 nights, so exactly equal is about 182 or 183. The statute presumes equal or approximately equal time and does not set a number. In Chan v. Chan, the court said it knew of no precedent that mathematically quantifies approximately equal time. On Form 14, the top line 11 band is 181 to 183 overnights.
Do holidays and summer count as overnights?
Yes. Form 14 counts every overnight awarded and exercised, including holidays, school breaks and summer weeks. In Bennett v. Bennett, counting them correctly moved a father from the 10 percent band to 15 percent.
Does this calculator tell me how much child support I will pay?
No. It produces the overnight count and the line 11 percentage. Enter that number on line 11 of our Missouri child support calculator to see the presumed amount.
What are Week One and Week Two?
They are the two alternating weeks Missouri parenting plan forms use to set a regular schedule. The statewide form defines them with a fixed table of dates. The week that begins with the first Sunday of January is Week One, the weeks alternate from there, and the count restarts each January. Choose Week One or Week Two in the calculator, or copy your plan’s chart into the custom option.
Is anything I enter saved?
No. The calculator runs entirely in your browser. Nothing is stored or sent to the firm, and using it does not create an attorney-client relationship.
This page gives general information about Missouri law as of October 2026 and is not legal advice. The calculator gives an estimate for planning, and a court decides overnights and child support on the facts of each case. Using it does not create an attorney-client relationship.
