Connecticut calculates in weekly net dollars
Convert each parent monthly net income to weekly income and use the official $50-$4,000 schedule.
Through $290 weekly net income, the darker low-income area uses the paying parent income alone.
Shared physical custody changes who pays but does not create an automatic overnight percentage.
Worked example: two children
- Convert $5,000 and $3,000 monthly net to weekly amounts.
- Round combined weekly income to the nearest $10 schedule row.
- Allocate the scheduled obligation by the rounded payer income share.
The steps above follow the calculation method described on our methodology page.
