Understanding the Rising Supermarket Food Prices: Insights from Which?’s Inflation Tracker


In recent times, the cost of groceries has been a cause for concern among consumers. With overall inflation reaching its highest level in over four decades, it is crucial to delve deeper into the factors driving the soaring prices. This blog post explores the groundbreaking insights provided by Which?’s monthly food inflation tracker, shedding light on the supermarkets, food and drink categories, and rising prices that demand our attention.

A Comprehensive Analysis

Which?’s inflation tracker stands out for its ability to provide a thorough examination of supermarket food and drink inflation. By analyzing tens of thousands of prices, the tracker uncovers valuable insights, including:

1. Monthly Comparison: The tracker reveals which supermarkets experience the highest and lowest inflation rates every month.

2. Food and Drink Categories: It identifies the types of food and drink with the most significant price increases, giving consumers an understanding of where their budgets are most affected.

3. Brand Comparison: The tracker examines the disparity between the price increases of branded and own-label groceries.

4. Budget vs. Premium Products: It highlights whether budget ranges or more premium offerings are experiencing faster price escalations.

Tracking Methodology

The inflation tracker focuses on 20 popular categories of food and drink across eight major supermarkets: Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco, and Waitrose. The analysis compares prices over three-month and one-month periods, year-on-year, considering discounts but excluding multibuys or loyalty card offers. The figures are weighted based on supermarket market share and sales volume for each product category.

Food Inflation in June 2023

In the three months leading up to June 30, 2023, the annual inflation rate for supermarket food and drink slightly decreased to 16.4%, down from its peak of 17% in the three months prior to the end of April. Comparing the one-month periods, inflation dropped from 16.5% to 15.4% in June 2023. These calculations are based on 24,391 product price points for the three-month period and 25,170 for the one-month period.

Insights on Two-Year Inflation
