| No add-ons | $600 a month A→B |
| Child care $500 a month | $909 a month A→B |

Child care, the children's health insurance premium and ongoing medical costs are shared by income share; the paying parent gets credit for what they pay directly. For uninsured children, cash medical support of $115 per child may apply, limited with the premium to 5% of the paying parent's gross income.
How Oklahoma works it out
Oklahoma uses the income shares model: the schedule gives the combined base monthly obligation for the parents' combined adjusted gross income, and each parent is responsible for their percentage share.
Gross income from almost all sources counts, before taxes. Self-employment income is reduced by 7.65%, the employer share of Social Security and Medicare tax. Means-tested benefits and child support received for other children don't count, and alimony between the parents is neither added nor deducted.
When the parent with fewer overnights has at least 121 a year, the combined obligation is multiplied by a factor from 2 down to 1.5, and each parent's share is offset against the other's for the time the children spend with the other parent. A parent with more than 205 overnights pays no basic support.
