OPINION ANNOUNCING THE JUDGMENT OF THE COURT
FLAHERTY, Justice.At issue in this case is whether a claimant in a fatal claim petition requesting compensation under section 307 of the Pennsylvania Workmen’s Compensation Act1 sustained her burden of proof that she was “dependent” upon her deceased child and therefore entitled to compensation under the act.
On November 9, 1990, Else B. Essel filed a fatal claim petition with the Bureau of Worker’s Compensation requesting compensation based on the death of her son, Brian K. Adams, who died as a result of work-related injuries on October 2, 1990. At hearings before a referee, claimant testified that she is a sixty-year-old widow, that her son provided financial support for her from 1989, while he was in the Navy, until his death in October 1990. He was discharged from the Navy in August 1990, moved in with his mother *598shortly thereafter, and went to work for Lineal Industries. Mrs. Essel also introduced evidence of her income and expenses. Her expenses included monthly mortgage payments ranging from $193.79 to $387.58 for a vacation home-trailer purchased in 1987 for $13,500. The referee found that the son was single, without dependent children, living with his widowed mother, and earning $425 per week at the time of his death. He also found that the mother’s average monthly income was $1322, her average monthly expenses were $1400, and that her son contributed approximately $583 per month to his mother from January 1990 through September 1990. The referee concluded, therefore, that Mrs. Essel had sustained her burden of proof that she was partially dependent upon her son at the time of his death and that she was entitled to compensation under the fatal claim petition.
The Workmen’s Compensation Appeal Board affirmed the referee’s determination and the employer appealed to Commonwealth Court. Commonwealth Court reversed, holding that the cost of Mrs. Essel’s vacation trailer-home was not an ordinary necessity of life and, therefore, should have been excluded from the referee’s calculation of expenses. Had it been excluded, Mrs. Essel’s expenses would not have exceeded her income and she would not, therefore, be “dependent” under the act.
We granted Mrs. Essel’s petition for allowance of appeal to review Commonwealth Court’s interpretation of the statutory requirement of dependency under the act.
Section 307 of the Pennsylvania Workmen’s Compensation Act, 77 P.S. § 561, provides for compensation benefits to dependent parents of a deceased employee as follows:
In case of death, compensation shall be computed on the following basis, and distributed to the following persons.... If there be neither widow, widower, nor children entitled to compensation, then to the father or mother, if dependent to any extent upon the employee at the time of the injury....
(Emphasis added.) Commonwealth Court has described a parent’s dependency under the act as follows:
*599The test of dependency is whether or not the child’s earnings were needed to provide the parents with some of the ordinary necessities of life suitable for persons in their class and position, and that the parents were, consequently, dependent to some extent upon the child at the time of the accident causing his death.... If the contribution of the deceased child were necessary to maintain the parents in an established reasonable standard of living, this existing standard must be considered in determining the necessity for such contribution from the child.

Our standard of review is whether the necessary findings of fact are supported by substantial evidence, whether the lower court committed an error of law, or whether constitutional rights have been violated. Bethenergy Mines, Inc. v. Workmen’s Compensation Appeal Board, 531 Pa. 287, 612 A.2d 434 (1992).
Mrs. Essel’s view is that Commonwealth Court’s holding that the vacation home was excludable from the dependency calculation because it was not an “ordinary necessity of life” was error. We will address this claim after first considering the employer’s arguments that in addition to the vacation home matter, other considerations defeat appellant’s claim for compensation.
To begin with, the employer asserts that the referee erred in calculating the claimant’s income at $1322 per month and her expenses at $1400 per month. In support of this claim, the employer points out that included in claimant’s expenses is the cost of a headstone for her son, a capital expense that should be excluded from the calculation of ordinary monthly expenses, and that if the cost of the headstone is removed, claimant’s expenses would be $1362 per month. Employer also asserts that the referee erred in calculating Mrs. Esser’s monthly income at $1322 and that it should have been calculated at $1391.78.
*600The argument as to Mrs. Esser’s income fails because the employer has not preserved the issue of claimant’s income for review.2 The income, therefore, for purposes of this appeal, remains at $1322 as set by the referee, and even if the expenses are adjusted downward to $1362, as argued by the employer, the expenses still exceed the income and dependency is not defeated.3
Next the employer argues that if claimant is allowed to include the monthly expense for her trailer-vacation home, and if she is awarded benefits, the benefits should cease as of October 1994, when the trailer will be paid for.
The statutory scheme provides for limitations upon payment of compensation to various categories of beneficiaries. Section 307 provides for compensation to any child, brother or sister, *601for example, “only if and while such child, brother, or sister is under the age of eighteen unless such child, brother or sister is dependent because of disability ...” or until the child, brother or sister reaches twenty-three if he is enrolled in an accredited educational institution. There are also restrictions upon compensation to surviving spouses and “dependents”:
Should any dependent of a deceased employee die or remarry, or should the widower become capable of self-support, the right of such dependent or widower to compensation under this section shall cease except that if a widow remarries, she shall receive one hundred four weeks compensation at a rate computed in accordance with clause 2 of section 307 in a lump sum after which compensation shall cease.
77 P.S. § 562. According to this provision, compensation' payable to a dependent (the status sought by Mrs, Essel) ends (a) upon the death of the dependent or (b) upon the dependent’s remarriage. Compensation payable to a surviving spouse ends (a) when the surviving spouse dies, (b) when the surviving spouse becomes capable of self-support, or (c) upon remarriage of the surviving spouse.
In sum, section 307 sets limits upon compensation payable to children, brothers, sisters, dependents, and surviving spouses of the deceased. Mrs. Essel is not a child, brother, sister or widow of the deceased; rather, she is, in the terms of the statute, a “dependent.” Benefits to Mrs. Essel, therefore, are payable under the portion of the statute governing dependents. The statute terminates a “dependent’s” benefits upon death or remarriage. It does not provide other possible conditions for termination, as it does for children, brothers, sisters, widows and "widowers. We conclude, therefore, that once benefits are paid to a parent who is dependent, they are payable until the parent’s death or remarriage.
The question remains, however, whether Commonwealth Court was correct in holding that the monthly payment for the trailer-vacation home was excludable from the dependency calculation because it was not an “ordinary necessity of *602life.” The employer asserts that the mortgage payment for a second home “cannot be considered a necessary and ordinary expense,” and concludes that such an expense, therefore, is not includable in the calculation of dependency.
It will be recalled that Commonwealth Court in Leipziger v. Workmen’s Compensation Appeal Board stated: “The test of dependency is whether or not the child’s earnings were needed to provide the parents with some of the ordinary necessities of life suitable for persons in their class and position,” 12 Pa.Cmwlth. at 420, 315 A.2d at 885, supra. We agree with this interpretation of “dependency” under section 307.
In order to be eligible for compensation, the father or mother must “to any extent” be dependent upon the financial contributions of the deceased child. This means, simply, that when normal monthly bills extant at the time of the child’s death are set off against normal monthly income of the parent, there is a deficit, absent the child’s contribution. Further, in order to qualify as “dependent,” these regular monthly expenditures must be reasonable in light of the life circumstances of the parent at the time of the child’s death.
Here, the purchase of the trailer-vacation home occurred three years prior to the decedent’s death while Mrs. Esser’s husband was still living. The record indicates that Mrs. Essel acquiesced in her late husband’s desire to purchase the property. The total purchase price of the trailer-vacation home was $13,500 and it was to be paid off at the rate of approximately $194 per month over a period of seven years. Mrs. Esser did not incur this expense after her son’s death, but rather, it was a financial reality and a financial burden at the time of his death. Further, it was an expense appropriate to her life circumstances that was incurred at a time when she reasonably expected to be able to afford it. It is not, therefore, an unreasonable expense and is includable in her expenses for purposes of calculating her dependency under the act.

. See employer’s Appeal and Request for Supersedeas before the Worker’s Compensation Appeal Board, which states, in pertinent part:
6. This appeal is from referee's finding of fact number 8, 9, and 13. These' are contrary to the law and not supported by substantial competent evidence.
The referee’s Findings of Fact which were appealed are as follows:
8. At that time, the family’s monthly expenses were about $1,400.00 excluding October 1990.
9. At that time, decedent’s average monthly contribution toward those expenses was about $583.00 from January 1990 through September 1990. Since Claimant's Exhibit # 3 starts with January 1990, that date is used here also.
13. Claimant sustained her burden of proving that she was partially dependent upon decedent at the time of his fatal, work-related injuries.
The referee’s finding which employer did not appeal from was number 7:
7. Excluding decedent's income and contributions, the family’s total monthly income at that time was about $1,322.00.
. Appellee also argues that claimant’s expenses will decrease by at least $100 per month because of the death of her son, thus reducing her expenses to about $1300 per month, less than her income. An examination of claimant’s monthly expenses from January 1990 through December 1990, however, reveals that claimant’s expenses remained fairly constant: the average monthly expense for food and personal items over twelve months was $617, and for the two months claimant’s son lived with her, it was $637 per month. Average monthly expense for utilities over twelve months was $204 and for the two months claimant’s son lived with her, utility expense was $170 per month. We conclude, therefore, that claimant’s monthly expenses would not measurably decrease after her son’s death.
