When you hear something like “annual inflation is 5.5%”, that might sound bad, but it can be difficult to wrap your head around exactly what that looks like in terms of monthly expenses. The inflation rate is spread across the whole spectrum of goods and services, so it’s not as simple as just assuming everything will be 5.5% more expensive than the same time last year. Some prices fluctuate wildly, so much so that the ABS often refers to ‘underlying inflation’, which excludes goods with traditionally volatile prices like food and fuel.

This index aims to capture monthly changes to grocery prices. We hope it can be a useful resource to help you visualise how prices fluctuate over time, and perhaps help you identify savings you could be making on your weekly shop.

Notes on the index

  • Data is sourced from the Coles and Woolworths websites at the tail end of each month.

  • We’ve used home branded products wherever we can. In some cases, it made sense to go with branded products, but it should be pretty clear when we’ve done so. If there isn’t a brand listed, it is the Coles/Woolworths version of the product.

  • Where possible, we’ve ignored specials where the price is listed as temporary. In some cases though, prices are substantially lowered indefinitely, which has created a discrepancy in price between the supermarkets. An asterisk indicates these cases.

  • In some instances, the supermarkets do not have exact equivalent products. At Woolworths for example, single banana prices are listed, rather than a unit (per kg) price. When this happens, we’ve equivalised as best we can. With bananas for example, we took the average weight provided on the site, and worked out the per kilogram price. This means there might be a slight difference from the price you would pay in store. We’ve marked these cases with a ^.
