delivered the opinion of the court:
A former wife petitioned for increased child support. The circuit court of Lawrence County, Judge Robert M. Hopkins, increased the former husband’s child support payment to the statutory guidelines’ minimum of $824 per week. The former husband appeals, claiming that (1) the award is substantially greater than the reasonable needs of one child and (2) the court improperly employed income averaging for the purpose of establishing child support. We affirm.
I. BACKGROUND
Dr. Harry and Elizabeth Garrett’s marriage was dissolved in July 1993. At the time of their divorce, the Garretts had two children — a daughter, Allison, who was 1, and a son, Jeffrey, who was 11. Prior to the dissolution, the trial court had made a finding on a petition for interim relief that Harry’s 1992 net income for purposes of child support was $175,000 and that his net income would be somewhat reduced for 1993. Subsequently, the trial court approved a marital settlement agreement setting child support at $700 per week for the two children.
Harry appeals the decision of the trial court, arguing that the court abused its discretion by (1) setting child support at a level substantially greater than the reasonable needs of the child and (2) averaging his income for the previous three years to establish his obligation. We affirm the trial court’s decision.
II. ANALYSIS
A. Child Support
Motions to modify child support must be decided on the facts and circumstances of each case; therefore, the standard of review is whether the trial court abused its discretion. See In re Marriage of Singleteary,
Harry contends that the trial court should have deviated downward from the statutory guidelines (see 750 ILCS 5/505(a)(l) (West 2000)) because 20% of his net income provides a child support level substantially greater than the reasonable needs of the child. We recognize that there is one Illinois Supreme Court case, In re Marriage of Bussey,
Section 510(a)(1) of the Illinois Marriage and Dissolution of Marriage Act (Act) provides that a substantial change in circumstances will justify a modification of child support. 750 ILCS 5/510(a)(l) (West 2000). The burden of showing that a substantial change in circumstances has occurred is on the moving party. See In re Marriage of Bean,
Section 505(a)(1) of the Act sets forth guidelines for determining the percentage amount of child support. 750 ILCS 5/505(a)(l) (West 2000). Section 505(a)(2) then provides:
“(2) The above guidelines shall be applied in each case unless the court makes a finding that application of the guidelines would be inappropriate, after considering the best interests of the child in light of evidence including but not limited to one or more of the following relevant factors:
(a) the financial resources and needs of the child;
(b) the financial resources and needs of the custodial parent;
(c) the standard of living the child would have enjoyed had the marriage not been dissolved;
(d) the physical and emotional condition of the child, and his educational needs; and
(e) the financial resources and needs of the non[ ]custodial parent.
If the court deviates from the guidelines, the court’s finding shall state the amount of support that would have been required under the guidelines, if determinable. The court shall include the reason or reasons for the variance from the guidelines.” 750 ILCS 5/505(a)(2) (West 2000). The same guidelines and factors apply when the court considers an increase in child support. See In re Marriage of Bussey,
The question of whether to deviate downward from the statutory guidelines when dealing with above-average incomes presents a dilemma. The consideration of all the relevant factors “in the best interest of the child” can often end in the simple query of “how much is too much?” The jurist must keep in mind that what is considered reasonable by some families’ standards may be considered extravagant by other families’ standards. For example, most families would find a European vacation unthinkable, but for the privileged few it might be an annual event. Fortunately, the statute itself, by requiring express reasons for a downward deviation, affords safeguards against jurists imposing their personal beliefs of what is reasonable. See 750 ILCS 5/505(a)(2) (West 2000). Further, case law has imposed a presumption that the guidelines apply absent compelling reasons, which places the burden on the party urging the deviation. “[A] determination of child support under the Act begins with the presumption that the guidelines will be applied. Compelling reasons must exist in order to overcome that presumption and permit the court to deviate from the guidelines.” In re Marriage of Stanley,
Harry complains that the child support is a windfall to Elizabeth and that in its award the trial court should have considered the personal finances of Elizabeth.
Harry relies entirely on the decisions of In re Marriage of Singleteary and In re Marriage of Bush,
While we recognize that the support of a child is the joint obligation of the parents, it is clear that when one parent earns a disproportionately greater income than the other, that parent should bear a larger share of the support. See In re Marriage of Singleteary,
It is also clear from the record that Harry’s financial resources of more than $170,000 after paying Allison’s support are ample to meet his needs.
We conclude, as did the trial court, that Elizabeth established a substantial change in circumstances, entitling her to a modification in child support. We also conclude that Harry has not met his burden of justifying a downward deviation from the statutory support guidelines. See Department of Public Aid ex rel. Nale v. Nale,
B. Income Averaging
Harry’s second argument is that the trial court abused its discretion by averaging his income for the previous three years in order to establish the amount of child support owed. Although he recognizes that in some instances an income-averaging approach is necessary, Harry does not believe that it was appropriate under these circumstances. Instead, he believes that the trial court should have used only the 2000 projected net income figure of $164,836 in applying the statutory guideline. This calculation would have resulted in a child support obligation of $622 per week, and this figure would have been acceptable to Harry.
A trial court’s finding of net income is within the discretion of the trial court and will not be disturbed absent an abuse of that discretion. See In re Marriage ofFreesen,
Accordingly, we find that the trial court did not abuse its discretion in using income averaging under these circumstances.
III. CONCLUSION
For the foregoing reasons, we affirm the decision of the trial court modifying the support order to $824 per week.
Affirmed.
