Supermarkets challenger Aldi is saving Australian shoppers more than $2 billion on their national grocery bill each year, a new report shows.

The data produced with the help of business advisory firm PwC also found Aldi delivers a massive $3.3 billion in benefits a year to the national economy, mainly through its production and supplier partnerships.

“We’ve created careers for thousands of employees, driven enormous growth for private label manufacturers in Australia, and directed billions of dollars into the national economy via real estate, store construction, wages, business partnerships and taxes paid to government,” Aldi Australia CEO Tom Daunt said.

By comparing similar baskets of goods, the report found Aldi customers saved $2.2 billion a year compared to the other major supermarkets.

“Aldi (also) had a downward force on the price of all groceries resulting in savings of $450 million for customers that chose to shop elsewhere,” the report added.

Daunt used the report launch to pledge greater business transparency to the market.

“As one of Australia’s top three supermarkets, we believe that we have a responsibility to incentivise positive change,” he said.

“We are proud of the reputation we have built for providing customers with a high quality and affordable shopping alternative. As we look to our future in Australia, we want to reassure our customers that how we conduct our business is just as important to us as the low prices we offer.

“The economic impact report, launched today, goes a long way to highlight the extent of Aldi’s positive impact on the Australian economy. But, it remains only one part of a far reaching story.”
