Calculating Loss of Earning Capacity in Wrongful Death Claims: The Roberto Lopez Case

When a person dies due to a criminal act, the law allows the heirs to claim damages, including compensation for the income the victim would have earned had they lived. This is called loss of earning capacity. In the 2011 case of People of the Philippines v. Roberto Lopez y Cabal (G.R. No. 188902), the Supreme Court clarified how courts should compute this amount, providing a clear formula that remains relevant today.

The Facts of the Case

Roberto Lopez was charged with murder for shooting Prudencio Melendres on 31 July 2006. A prosecution witness testified that Lopez shot Melendres three times—on the head, chest, and lower abdomen—before fleeing the scene. Lopez denied the charges and presented an alibi, claiming he was working at a house repair job on the day of the incident. However, his own witness contradicted this on cross-examination.

The trial court found Lopez guilty of murder and sentenced him to reclusion perpetua. The Court of Appeals affirmed the conviction but modified the damages awarded. Lopez appealed to the Supreme Court, which upheld his conviction but further modified the award for loss of earning capacity.

The Issue

The main legal question was not about Lopez's guilt—which the Court affirmed—but about how to properly compute the loss of earning capacity suffered by the victim's heirs. The trial court had awarded P45,420 for lost income, while the Court of Appeals increased this to P200,000. The Supreme Court found both amounts incorrect.

The Ruling: The Formula for Loss of Earning Capacity

The Supreme Court emphasized that documentary evidence must substantiate any claim for loss of earning capacity. In this case, the victim's wife presented certifications from the victim's employer showing his salary range and his honoraria and transportation allowance for the seven months before his death.

The Court applied the standard formula:

Net Earning Capacity = Life Expectancy x Gross Annual Income – Living Expenses

Where:

• Life expectancy = 2/3 (80 – age at death)
• Living expenses = 50% of gross annual income

Since the victim was 41 years old at death, his life expectancy was computed as 2/3 (80 – 41) = 26 years.

For the gross annual income, the Court combined two sources: the average monthly salary of P2,675 (derived from the salary range of P1,780 to P3,570), which totals P32,100 annually, plus the honoraria and transportation allowance of P3,570 per month, totaling P42,840 annually. The combined gross annual income was P74,940.

Applying the formula:

• Net Earning Capacity = 26 years x (P74,940 – P37,470)
• Net Earning Capacity = 26 x P37,470
• Net Earning Capacity = P974,220

Key Principles Established

The Court reiterated several important rules in this case. First, documentary evidence is required to prove loss of earning capacity—a mere allegation is insufficient. Second, evidence not objected to by the opposing party is deemed admitted and may be considered by the court. Third, when the employer's certification provides only a salary range, the court may use the average of the amounts stated.

The Court also noted that the victim's honoraria and transportation allowance, being regular payments from his employer, formed part of his gross annual income for purposes of computing loss of earning capacity.

Practical Takeaways

• Document everything: Heirs claiming loss of earning capacity must present documentary evidence such as employment certifications, payslips, or tax records. Unsubstantiated claims will not be awarded.
• Know the formula: The standard formula is Net Earning Capacity = [2/3 (80 – age at death)] x Gross Annual Income – 50% of Gross Annual Income.
• Include all income sources: Regular allowances and honoraria from employment count toward gross annual income, not just the basic salary.
• Act on unobjected evidence: Evidence presented without objection is deemed admitted and can support a damages award.
• Life expectancy is fixed: The law presumes a life expectancy of 80 years, and the formula deducts the victim's age at death from this figure.
