Spending calculator: See which prices have gone up or down

Prices in March were 3.2% higher than prices at the same time last year, putting pressure on already stretched household budgets.

This figure, the lowest since 2021, is inching closer to the Bank of England’s 2% target.

Food prices rising by less than they did last year was the biggest driver of March’s overall inflation rate fall. That was partly offset by fuel prices rising this year when they were falling in March 2023.

A fall in inflation doesn’t mean prices are coming down but that they’re rising less quickly.

But how much has your individual spending changed?

Use our calculator to see how much prices are rising on the groceries, clothing and leisure activities you pay for.

Which prices are increasing fastest?

Olive oil costs 39% more than it did last year, with prices for 500ml-1 litre rising from £5.78 to £8.04 in just 12 months. Plums are up by nearly a quarter, from £2.91 per kilo to £3.63.

Food and drink products are responsible for five of the 10 highest increases since last year, with the others being cigarettes, tobacco, plant seed and a boy’s t-shirt – they are all roughly a fifth more expensive compared with the same time last year.

Top five price rises:

• Olive oil (500ml-1 litre): up 39%, £5.78 to £8.04
• Plums (per kg): up 25%, £2.91 to £3.63
• Hand rolling tobacco pack (30g): up 24%, £18.55 to £23.09
• Carrots (per kg): up 22%, 64p to 78p
• Plant seeds: up 19%, £1.89 to £2.25

Thirty-nine of the 189 types of food and drink tracked by the ONS have actually become cheaper since last year. Many of these were dairy items like milk and butter, as well as dried pasta.

Overall, 117 out of the 444 products in our database are cheaper than they were this time last year.

Top food price decreases:

• Dry spaghetti or pasta (500g): down 13.1%, £1.07 to 93p
• Spreadable butter (500g): down 13%, £4.37 to £3.80
• Whole milk (4 pints): down 11.2%, £1.70 to £1.51
• Butter (250g): down 10.1%, £2.36 to £2.12
• Frozen prawns (per kg): down 8.7%, £18.55 to £16.94

Of non-supermarket items, electric heaters have been some of the biggest price fallers – by more than 20%.

What is the effect of long-term inflation?

The price changes described above compare the cost of items to where they were a year ago.

However, inflation has now been at high levels for an extended period of time.

The war in Ukraine, COVID, Brexit, and other supply chain pressures have all contributed to spiralling costs in recent years.

Inflation reached a 40-year high of 11.1% in October 2022.

While the headline inflation figure is finally starting to come down, any amount of inflation means that prices are still rising, and building on already inflated costs.

We’ve compared the costs of shopping items to what they were three years ago to see what the cumulative impact of inflation has been.

The biggest price rise for groceries over that time has been for olive oil (500ml-1 litre) which has more than doubled, from £3.51 to £8.04 in the past three years.

Sugar is also up by 75% on average, with a kilogram bag costing £1.19 now compared with 68p in March 2021.

Use our calculator to see how much prices in your shopping basket have risen in total since three years ago.

Who is worst affected?

Richard Lim, chief executive of Retail Economics, says: “It’s the least affluent households that are going to see much higher rates of inflation as they spend more of their income on food and energy.”

We’ll continue to update our spending calculator over the coming months so you can see how you’ll be affected.

Methodology

The ONS collects these prices by visiting thousands of shops across the country and noting down the prices of specific items. There are upwards of 100,000 prices published every month, from more than 600 products.

The items that form the “official shopping basket” change each year to reflect how the purchasing habits of the population have changed. For example in March 2021, after a year of the pandemic, hand gel, loungewear bottoms and dumbbells were added, while canteen-bought sandwiches were among the items removed.

Where there aren’t the exact equivalent items available at a survey shop, ONS officials pick the best alternative and note that they’ve done this so it’s weighted correctly when the averages are worked out.

Shops are weighted as well, so the price in a major chain supermarket will have a greater impact on the average than an independent corner shop.

We will be updating these figures each month while the cost of living crisis continues.

During the pandemic, more of the survey was carried out over the phone and work is ongoing to digitise the system to be able to take in more price points by getting data from supermarket receipts, rather than making personal visits.
