tial parents at all times. Thus, this part of division (C) is likewise inapplicable to this case.
Instead, we find that R.C. 3113.215(B)(6)(a), rather than R.C. 3113.215(C), applies to child support under a shared parenting order. Calculation of child support under R.C. 3113.215(B)(6)(a) is quite clear. Child support is calculated in accordance with the basic child support schedule and the worksheet set forth in division (E), through line 24 (the annual obligation). The statute allows for a deviation from that amount only where “the application of the schedule and the worksheet, through line 24, would be unjust or inappropriate to the children or either parent and would not be in the best interest of the child because of the extraordinary circumstances of the parents or because of any other factors or criteria set forth in division (B)(3) of this section “Extraordinary circumstances of the parents” is defined to include the amount of time the children spend with each parent, the ability of each parent to provide adequate housing for the children, and the amount of expenses each parent sustains. R.C. 3113.215(B)(6)(b)(i), (ii), and (in).
Appellant seeks an automatic credit for the time he has cared for his children. R.C. 3113.215(B)(6) does not provide for an automatic credit in child support obligations under a shared parenting order. However, a trial court may deviate from the amount of child support calculated under R.C. 3113.215 if the court finds that the amount of child support would be unjust or inappropriate to the children or either parent and would not be in the best interest of the child.
Thus, only after consideration of the extraordinary circumstances of the parents and other factors set forth in R.C. 3113.215(B)(3) may a trial court deviate from the amount of child support listed in line 24 of the worksheet and reduce the obligor’s child support obligations accordingly. Rather than requiring an automatic credit in all instances, this method permits a court to make an evaluation on a case-by-case basis and to deviate when it finds it is in the best interest of the child. In this manner, a court is able to take into account the specific facts of each case.
We have held previously that “[t]he terms of R.C. 3113.215 are mandatory in nature and must be followed literally and technically in all material respects.” Marker v. Grimm (1992), 65 Ohio St.3d 139, 601 N.E.2d 496, paragraph two of the syllabus. In this case, the magistrate complied with the requirements of R.C. 3313.215(B)(6)(a). The magistrate calculated the amount of child support by using the applicable schedule and worksheet. In his findings of fact and conclusions of law, the magistrate considered whether the extra time appellant spent with his children warranted a deviation from the amount of child support he was obligated to pay through line 24 of the child support worksheet. The magistrate found that the extra time appellant spent with them was not exten
