|---|---|---|---|---|
| Every other weekend plus extras | 4 | 31 | 135.29 | 37.07% |

Formula Used
Recurring schedule estimate:
Parent B yearly overnights = (Parent B overnights per 14 days ÷ 14 × 365) + summer overnights + holiday overnights + vacation overnights + 12-hour blocks + half-day blocks × 0.5 - duplicate deductions + yearly adjustment.
Two-year average:
Average overnights = (Year 1 overnights + Year 2 overnights) ÷ 2.
Parenting percentage:
Parenting percentage = Average overnights ÷ 365 × 100.
Credit percentage estimate:
Credit percentage = 1 ÷ (1 + e-7.14 × ((overnights ÷ 365) - 0.5)) - 0.0274 + 2 × 0.0274 × (overnights ÷ 365).
Optional credit amount:
Minor children portion = combined basic support ÷ eligible children × minor children. Estimated credit amount = minor children portion × credit percentage.

Planning Parenting Time in Oregon
Why Overnight Counting Matters
Parenting time planning works best when each overnight is counted clearly. Oregon families often use written plans to reduce confusion. A written plan can show school nights, weekends, holidays, vacations, and exchanges. This calculator turns those schedule details into yearly estimates. It also compares each parent’s annual share. That helps parents see whether the plan is balanced.
Using a Two-Year View
Many schedules change from year to year. Holidays may alternate. Summer weeks may rotate. Birthdays and school breaks can shift. A two-year average gives a smoother picture. It prevents one unusual year from controlling the full estimate. The manual method is useful when you already have a calendar count. The pattern method is helpful when the plan repeats every two weeks.
Handling Special Time Blocks
Some plans include long daytime care without an overnight. Other plans include partial-day blocks. This calculator includes fields for those situations. Add them only when they match your records. Avoid double counting a block that already overlaps an overnight. Use the deduction field when holiday time replaces regular time. Clear notes make the result easier to review later.
Reading the Result
The result shows annual overnights, percentages, and credit estimates. It also labels the schedule balance. These numbers are planning aids. They are not a court order. They do not prove actual parenting time. Keep calendars, messages, school schedules, and signed agreements. Review the final figures with Oregon’s official calculator when support is involved. For legal questions, speak with a qualified Oregon professional.
Frequently Asked Questions
1. Is this an official Oregon calculator?
No. It is a planning calculator. Use Oregon’s official tools, signed agreements, court orders, and qualified advice for legal decisions.
2. What does Parent B mean here?
Parent B is the parent whose schedule you enter. Parent A is calculated as the remaining annual time, based on 365 days.
3. Why does the form use a 14-day cycle?
Many parenting plans repeat every two weeks. A 14-day cycle captures alternating weekends, weekday visits, and shared schedules more easily.
4. What are duplicate deductions?
Use duplicate deductions when extra holiday or vacation nights are already included in the repeating schedule. This helps prevent double counting.
5. Can I enter exact yearly totals?
Yes. Select manual two-year entry. Then enter Parent B’s year one and year two overnight totals directly.
6. Does this calculate final child support?
No. It estimates parenting time and an optional credit amount. Full support calculations require many additional Oregon guideline factors.
7. Should I include summer and holidays?
Yes, include them when they add overnights beyond the regular pattern. Subtract overlaps if they replace regular scheduled nights.
8. Why export CSV or PDF?
Exports help save assumptions, compare plans, and share records during planning discussions. Keep official documents separately.
