Brian Joseph Riggan (Defendant) appeals from a child custody order entered 18 October 2011. Defendant and Erin Michelle Reams (Plaintiff) had a child together (the child), bom 17 January 2005. Plaintiff and Defendant were never married. Plaintiff filed a complaint for child custody and child support on 5 April 2010. Defendant answered and counterclaimed on 14 May 2010. Both Plaintiff and Defendant sought sole custody of the child and child support. The trial court heard the matter on several dates between August and October 2011, and entered a custody order on 18 October 2011. The following are relevant findings of fact from the custody order:
6. That the Plaintiff and Defendant separated as is hereinabove set forth in January, 2006, because of indifference and failure and inability to communicate, and thereafter the Plaintiff and the Defendant lived separate and apart at all times thereafter.
7. That subsequent to the separation of the Plaintiff and the Defendant the Plaintiff and her minor child relocated their residence to Youngsville, located in Franklin County, North Carolina, and that since the relocation of the Plaintiff and the Defendant the minor child . . . has become enrolled, attended, and presently attends Youngsville Elementary School, which is a “year-round” school, and that while she has been at said school said child has been “doing well”.
8. That since the separation of the Plaintiff and the Defendant both the Plaintiff and the Defendant have married, and that they have married individuals other than each other, with the Plaintiff living with her present husband in Youngsville, North Carolina, and the Defendant living with his present wife in Henderson, Vance County, North Carolina.
*8015. That the Plaintiff is presently employed as a bartender at Carolina Ale House located in Wake Forest, North Carolina, and that she has been employed at the Carolina Ale House for the last four years next preceding the hearing of this action, and that from such employment the Plaintiff earns between Five Hundred and no/100 ($500.00) Dollars and Seven Hundred and no/100 ($700.00) Dollars per week, and that her hours of work extend on a weekly basis of Monday through Friday from 10:00 A.M. until 4:00 P.M.
16. That the Defendant is employed as maintenance foreman at Eastern Minerals, Inc. located in Henderson, North Carolina, and he has been so employed for more than three years next preceding the hearing of this action, and that he has a weekly work schedule which extends Monday through Friday from 7:30 A.M. until 4:00 P.M.; further, the Defendant earns Fourteen and 22/100 ($14.22) Dollars per hour and that he works forty hours per week,... but that he currently does not have employment benefits which provides health insurance for the use and benefit of the Defendant and/or his dependents.
17. That following the separation of the parties in 2006, the Defendant exercised visitation and manifested interest in the minor child ... on a sporadic basis; that the Defendant has visited the minor child’s school once since she has been attending Youngsville Elementary School, and that upon the Plaintiff first enrolling the minor child in school the Defendant objected to such enrollment; that the Plaintiff transports the minor child . . . to and from school on a daily basis, and that she helps the minor child with her homework and reading skills on a daily basis.
18. That since the birth of [the child] the Plaintiff has been the primary caregiver and has had the basic responsibility for the rearing, upbringing, raising and nurturing of the minor child . . . since the birth of said child; that the Defendant has exercised regular visitation with the minor child since shortly after the filing of this action.
*8120. That effective March 1, 2007, the Defendant was ordered to pay child support for the use and benefit of the minor child . . . and that the Defendant thereafter paid approximately One Hundred and no/100 ($100.00) Dollars under and pursuant to this order, although said order extended up to and through November 1, 2007, at which time the Plaintiff agreed, executed and signed documents waiving child support, and that the Defendant did not pay child support before March 1, 2007 and he has not paid child support subsequent to November 1, 2007.
22. That the Plaintiff and the Defendant are both gainfully employed and that from said employment the Plaintiff and the Defendant derive wages with which to contribute to the support and maintenance of the minor child . . . and that both of them ought to contribute to the support and maintenance of said minor child in conformity with the North Carolina Child Support Guidelines.
23. That, both the Plaintiff and the Defendant have adequate dwellings and facilities in which to maintain a minor child during the time each of them is exercising custody of or visitation privileges with said minor [child] as is hereinafter set forth. •
Based in part on these uncontested findings of fact, the trial court concluded the following:
7. That both the Plaintiff and the Defendant are fit and proper persons to have and to exercise care, custody, control and supervision of the minor child, and that both the Plaintiff and the Defendant have adequate dwellings and facilities in which to look after and provide for said minor child, and that the Plaintiff and the Defendant both have income with which to contribute to the support and maintenance of said minor child.
8. That the Court determines that it is in the best interest and general welfare of the minor child . . . that the *82Plaintiff should have primary custody of said child at all times hereafter and that the Defendant should be awarded reasonable visitation privileges with said minor child at all times hereafter as shall be hereinafter set forth.
The trial court then ordered that Plaintiff have primary custody of the child, granted Defendant visitation rights, ordered Defendant to pay child support in the amount of $390.41 per month, ordered Defendant to obtain health insurance for the child within sixty days, and dismissed Defendant's counterclaim. Defendant appeals.
I.
The issues on appeal are whether: (1) evidence supports certain of the trial court’s findings of fact, (2) the trial court erred in requiring Defendant to obtain health insurance for the child, and (3) the trial court required Defendant to pay too much in child support.
II.
The order we are reviewing on appeal is a child custody order.
Under our standard of review in custody proceedings, “the trial court’s findings of fact are conclusive on appeal if there is evidence to support them, even though the evidence might sustain findings to the contrary.” Whether those findings of fact support the trial court’s conclusions of law is reviewable de novo.
Mason v. Dwinnell, 190 N.C. App. 209, 221, 660 S.E.2d 58, 66 (2008) (citations omitted).
The trial court’s entire objective in [custody] cases is to determine the best environment for the child or children. . . . [T]hese decisions are often difficult, but even where parents love their children, “a parent’s love must yield to another, if, after judicial investigation, it is found that the best interest of the child is subserved thereby.” Of necessity in these cases, the trial court is vested with wide discretion. “[The trial court] has the opportunity to see the parties in person and to hear the witnesses, and [its] decision ought not be upset on appeal absent a clear showing of abuse of discretion.” “[The trial court] can detect tenors, tones, and flavors that are lost in the bare printed record read months later by appellate judges.”

III.
[1] Defendant challenges findings of fact seventeen through twenty-one, and from these challenges argues:
[The] conclusion that it is in the child’s best interest for [Plaintiff] to have primary custody was based in at least some part on the [trial court’s] belief that [Defendant] had never been fully involved in his child’s life as stated in the errant findings of fact 17 and 18. Because that “fact” is not actually a fact, the trial court’s basis for it’s [sic] conclusion is not fully founded and should be reconsidered upon remand.
Finding of fact nineteen involved a domestic violence protective order filed by Plaintiff, but subsequently dismissed by the consent of both parties. Finding of fact twenty-one is in reality a conclusion of law. Neither is relevant as a finding of fact, and we have not included them above. Concerning findings seventeen, eighteen, and twenty, although Defendant has presented some evidence contradicting some portions of these findings, Defendant’s argument still fails. After careful review of the record, we hold that there is substantial evidence in support of these findings and, therefore, they are binding on appeal. Mason, 190 N.C. App. at 221, 660 S.E.2d at 66.
■ We note that Defendant makes no argument that the trial court’s decision to award primary custody to Plaintiff constituted an abuse of discretion, and we shall not attempt to make Defendant’s argument for him. We further hold that we find no abuse of discretion. We affirm the trial court’s award of primary custody to Plaintiff, and the visitation schedule included in the custody order.

[2] Defendant argues that the trial court erred in ordering him to provide medical insurance for the child. We disagree.
Specifically, Defendant argues that the trial court’s order requiring Defendant to obtain health insurance for the child violated a statutory mandate. N.C. Gen. Stat. § 50-13.4(cl) (2011) directs that “the Conference of Chief District Judges shall prescribe uniform statewide presumptive guidelines for the computation of child support obligations of each parent].]” The North Carolina Child Support *84Guidelines (2011), Health Insurance and Health Care Costs, states in relevant part:
The court may order either parent to obtain and maintain health (medical or medical and dental) insurance coverage for a child if it is actually and currently available to the parent at a reasonable cost. Health insurance is considered reasonable in cost if it is employment related or other group health insurance, regardless of delivery mechanism. If health insurance is not actually and currently available to a parent at a reasonable cost at the time the court orders child support, the court may enter an order requiring the parent to obtain and maintain health insurance for a child if and when the parent has access to reasonably-priced health insurance for the child.
The trial court found that Defendant's employment did not provide health insurance benefits. Defendant argues that, because his employer does not provide health insurance benefits, he cannot obtain health insurance for the child at a reasonable cost as defined in the guidelines.
First, the guidelines state: “Health insurance is considered reasonable in cost if it is employment related or other group health insurance, regardless of delivery mechanism.” Id. Defendant makes no argument that he does not have access to “other group health insurance.” Second, we do not interpret this sentence as defining the only two methods through which health insurance may be determined to be “reasonably-priced.” We interpret this sentence as stating that, if a parent has access to employment-related or other group health insurance, this insurance will be considered “reasonably-priced” as a matter of law. This does not preclude the trial court from determining that some other health insurance is also reasonably priced. The custody order does not violate N.C.G.S. § 50-13.4(cl) merely because the trial court ordered Defendant to purchase health insurance for the child when Defendant did not have access to employment-related health insurance.
Defendant also argues that the trial court violated N.C. Gen. Stat. § 50-13.4(c), which states: “If the court orders an amount other than the amount determined by application of the presumptive guidelines, the court shall make findings of fact as to the criteria that justify varying from the guidelines and the basis for the amount ordered.” *85Defendant argues that the trial court deviated from the guidelines by requiring him to obtain health insurance for the child even though Defendant’s employer Alid not provide health insurance benefits. Because we hold that the trial court did not vary from the guidelines by ordering Defendant to obtain health insurance for the child even though Defendant did not have employer-funded health insurance, we also hold that the trial court did not violate N.C.G.S. § 50-13.4(c) by failing to make specific findings of fact on this matter.
Defendant does not argue that the trial court erred by failing to make sufficient findings in support of its ruling that Defendant should provide health insurance for the child. Likewise, Defendant makes no argument that any health insurance premiums he pays for the child should be factored into his child support payments. Therefore, these issues are not before us. Belk ex rel. Belk v. Belk,_N.C. App._., _., 728 S.E.2d 356, 359 (2012) (arguments not made in appellant’s brief are abandoned). This argument is without merit.
The dissent states Defendant does argue that “the trial court erred by failing to make specific findings of fact with regard to the availability of medical insurance.” Defendant’s argument concerning “specific findings of fact” was solely directed to Defendant’s assertion that the trial court had deviated from the guidelines and, therefore, N.C.G.S. § 50-13.4(c) required the trial court to justify deviation from the guidelines through specific findings of fact. Because we have held that Defendant has not shown a deviation from the guidelines, the requirements of N.C.G.S. § 50-13.4(c) are inapplicable. Defendant’s argument on appeal concerning the lack of findings of fact is limited to his argument concerning N.C.G.S. § 50-13.4(c), and does not apply to Defendant’s argument in general. If, as the dissent states, this is the core of Defendant’s argument, Defendant has failed to make this argument properly.
While it is true that the heading of Defendant’s argument states that there was no evidence of the availability of reasonably priced medical insurance, the only evidence, or lack thereof, actually addressed in Defendant’s argument is Defendant’s testimony that he does not have employer provided health insurance. Defendant simply does not make any argument that he has no access to other reasonably-priced health insurance, and, importantly, Defendant does not argue that the trial court erred by failing to make findings concerning any other reasonably-priced health insurance available to Defendant. We refuse to make additional arguments for Defendant. Belk,_N.C. App. at_, 728 S.E.2d at 359.
*86We agree with the statement of law concerning the trial court’s duty to make the appropriate determinations and support its ruling with sufficient findings of fact, and that it is not Defendant’s burden to insure that the trial court meet its duty. It is, however, Defendant’s duty to comply with the North Carolina Rules of Appellate Procedure and present our Court with an argument, supported by citations to relevant law, for every issue Defendant would like our Court to address. N.C.R. App. P. 28(b)(6). We have not shifted the trial court’s burden to Defendant. We are dealing with two entirely independent burdens — one at the trial level and one for appeal.
V.
[3] Defendant finally argues that the trial court erred in its calculation of the amount of child support Defendant was ordered to pay. We disagree.
Defendant’s argument is that he earns $14.22 per hour and works forty hours a week — thus, Defendant earns $568.80 per week. None of these amounts are contested. However, Defendant argues that, in order to determine his gross monthly income, the $568.80 figure should be multiplied by four, because there are four weeks in a month. There are, however, more than four weeks in a month, and Defendant cites nothing in his brief to support his position. The trial court determined that Defendant’s gross monthly income was $2,445.84, which is $568.80 multiplied by 4.3. Plaintiff contends that this is the common multiplier used to determine gross monthly income when gross weekly income is established. We need not address this contention because Defendant provides no support for his argument that the trial court erred in its calculation. Belk,_N.C. App. at_, 728 S.E.2d at 359 (Rule 28 of the North Carolina Rules of Appellate Procedure requires sufficient argument to be made in support of an appellant’s contention and citations in support of the argument. Failure to properly argue an issue on appeal results in abandonment of that argument.).
We further note that when Defendant’s $568.80 weekly income is multiplied by the fifty-two weeks in a year, then that amount is divided by the twelve months in a year, a monthly income of $2,464.80 is derived, which is greater than Defendant’s gross monthly income determined by the trial court — $2,445.84. Defendant has failed to show that the trial court erred, or that any error prejudiced him.
We again agree with the dissent that the record before us is unclear concerning exactly how the trial court reached its child sup*87port amount determinations. The dissent states that “it appears Plaintiffs monthly income was calculated using a multiplier of four on a weekly income of $600.” Though this seems a reasonable assumption, it is an assumption we are not free to make. It is possible, though unlikely, that the trial court applied a multiplier of 4.3 to both Plaintiffs and Defendant’s monthly income. Unfortunately, the record does not indicate what multiplier the trial court applied, nor what specific monthly income the trial court settled on for either party.
The dissent also correctly points out that the record fails to indicate that the trial court properly verified the incomes of the parties through documentation. However, these issues are not argued by Defendant on appeal. Defendant makes no argument that the record is deficient, that the trial court failed to make sufficient findings of fact, that the trial court improperly calculated either party’s monthly income, or that the trial court applied different formulas in calculating the parties’ gross monthly incomes. Defendant does not argue that this matter should be remanded to the trial court for additional evidence or findings, or that the trial court should apply a multiplier of 4.3 to Plaintiff’s monthly income. Instead, Defendant makes a number of unsupported assumptions and then argues this Court should order that his monthly child support obligation be reduced. Based upon the argument Defendant has actually made on appeal, we find it to be without merit.
Affirmed.
