The bare food essentials such as fruit, vegetables and dairy are part of our weekly grocery shopping lists right around the world, but how does the cost of these necessary items vary from one country to another?
While tastes and preferences vary around the world, the basics of our average weekly food shops are broadly similar, whether it's fruit and vegetables, or staple foods such as rice and eggs.
However, the cost of an essential grocery shop still differs considerably from one country to the next.
Unfortunately, due to the cost of living crisis, the price of food items is set to increase even further, bringing the UK's basket total to more than the current £60.59. Find out which food items have seen the most significant increases and decreases via our cost of living statistics page.
If you’re looking to save money on your grocery shop, many supermarkets offer their own credit cards, with a range of benefits for shopping with them, you can compare credit cards to see if you could save.
With that in mind, our personal finance experts analysed the average cost of a weekly shop in 36 countries around the world, as well as how these costs stack up against average earnings in each country.

Looking at each OECD country, an average weekly shopping basket of goods was created based on the average shopping habits of a family in the UK.
The average price of this basket in each of these countries was then sourced using Numbeo (note that some prices were adjusted to create a more realistic basket of goods, for example, while the price given for a round of beef was given for 1kg this was converted to 100g).
This was then compared against the average wage in each country according to OECD.Stat, with the weekly grocery cost and average annual wage both being converted into monthly figures to allow for a comparison.
