According a report by Bloomberg News, a hike in the federal minimum wage from $7.25 to $10.10 an hour might only cost consumers an additional penny on a $16 purchase.

A boost in the minimum wage to $10.10 would add $200 million โ€” or less than 1 percent โ€” to Wal-Martโ€™s annual labor bill, the University of California Berkeley Center for Labor Research and Education estimates.

If Wal-Mart passed along the estimated $200 million in extra labor cost to consumers, it would equal about a penny per $16 item, said Ken Jacobs, the Labor Centerโ€™s chairman. Meanwhile, the rise may boost purchases among the chainโ€™s core shoppers, many of whom could see their earnings climb, he said.

Walmart has remained neutral in the current minimum wage debate, but actually lobbied on behalf of a higher wage floor the last time it was raised. โ€œThe U.S. minimum wage of $5.15 an hour has not been raised in nearly a decade, and we believe it is out of date with the times,โ€ then CEO H. Lee Scott said in a speech in 2005. โ€œOur customers simply donโ€™t have the money to buy basic necessities between pay checks.โ€ The same is true today.
