How much have your groceries really gone up?

The official inflation rate averages a basket you don't buy. Put in the things you do buy, with an old price and a new one from your receipts, and see your own rate, including the packs that shrank while the price stayed put.

What you buy

Example

Old price from an old receipt, new price from the latest one. Sizes can differ: the comparison is per ounce, gram or item.

Weighted by what you spend on each product now.

About $10.64 more a month for the same packs at the old unit prices.

Let your receipts do this

Sorayli's price tracker reads every product line from your scanned receipts and works this out for you, shop by shop, with no typing.

How it's worked out

  1. Each price becomes a unit price: per gram, per millilitre or per item. A 10 oz bag at $10.49 and a 12 oz bag at $9.99 are compared ounce for ounce.
  2. A product's change is its new unit price against its old one.
  3. Your basket is the average of those changes, weighted by what you spend on each product now (new price × how many you buy a month). A 30% rise on spices moves it less than 10% on milk you buy every week.
  4. This is the same definition Sorayli's price tracker uses on your scanned receipts. How insights work.

Where do I find old prices?

On old receipts, in your shop's app or order history, or in a budgeting app that kept the line items. Use the same shop for both prices where you can, so you compare the price, not the shop.

What if the pack size changed?

Enter each price with its own size. The calculator compares per ounce, gram, millilitre or item, so a smaller pack at the same price shows up as the rise it is.

Why is my number different from the news?

Official figures average thousands of products across the country. Yours covers only what you buy, weighted by how much you buy, so it can be well above or below the headline rate.
