Employment Cost Index turns 50, a sharper lens for Home Depot pay pressure

When a Home Depot manager is trying to cut turnover or fill openings before a spring project rush, the first question is not how many people are on the floor. It is whether pay and benefits are really getting more expensive, or whether the store is simply seeing a different mix of cashiers, freight workers, department leads and Pro Desk roles. That is where the Employment Cost Index, now 50 years old, gives managers a cleaner read than a headcount snapshot.

The U.S. Bureau of Labor Statistics said the index’s first news release covered wage and salary changes from September 1975 to March 1976, and that it was designed to measure compensation costs without being distorted by shifts in industries, occupations or geographic areas. The agency classifies the ECI as a Principal Federal Economic Indicator, which puts it in the same core set of measures economists use to gauge labor-market pressure. In the latest reading, total compensation for civilian workers rose 3.4% over the year ending March 2026, private-industry wages and salaries were up 3.4% from March 2025 to March 2026, and private-industry total compensation rose 0.9% in the first quarter of 2026 on a seasonally adjusted basis.

For Home Depot, that distinction matters because the company’s labor costs do not move in one straight line. In its Feb. 21, 2023 results, The Home Depot said persistent inflation, global supply-chain disruptions and a tight labor market were shaping the business environment, and it said it would invest an additional approximately $1 billion in annualized compensation for frontline, hourly associates starting in fiscal 2023. Ted Decker said the move was intended to help the company attract and retain the talent needed to sustain the customer experience. Later company filings continued to point to competitive wages and benefits, training and career development as part of the retention strategy.

The ECI also shows why managers should not stop at hourly pay. Benefit costs were first added to the index in the September 1987 release, with historical data back to 1979, and employers’ costs for benefits had risen 558.8% from December 1979 as of March 2026. Home Depot’s benefits page lists medical, dental, vision, health savings accounts, disability, life insurance, paid holidays, paid maternity and parental leave, vacation, sick time and employee assistance resources, with some coverage varying by full-time, part-time, salaried or temporary status.

That broader picture matters at scale. The Home Depot said it was founded in 1978, now operates more than 2,300 stores in the U.S., Canada and Mexico, and reported fiscal 2025 net sales of $164.7 billion and earnings of $14.2 billion. For managers, the lesson is straightforward: if compensation pressure is rising, the ECI helps show whether the problem is real, where it is coming from and whether pay, benefits or staffing mix is driving it.
