Inflation decreased to 10.1% in January 2023, according to data from the Office for National Statistics (ONS), partly due to cheaper passenger transport and motor fuels.

The Consumer Prices Index (CPI) measure of inflation, which tracks the cost of an imaginary 'shopping basket' of around 700 popular goods and services, is down from 10.5% in December 2023. 

Here, Which? explains why the inflation rate has fallen, and how it compares to the top-rate savings accounts and cash Isas. We also share tips for tackling the rising cost of living.

Why has inflation fallen?

The main reason inflation eased up a bit in January was down to cheaper prices for motor fuels and passenger transport - particularly air fares and coach fares. Prices for restaurants and hotels were also cheaper when compared to the same time last year.

However, there were several price rises that meant inflation was kept in double figures - namely rising prices for alcoholic drinks and tobacco. 

The graph below shows how inflation has changed since January 2019:

The Bank of England’s target is to keep inflation as close to 2% as it can. But it hasn’t been that low since July 2021. Before that, inflation was very low. It was below 2% from August 2019 to April 2021, falling to a low of 0.2% in August 2020 due to the pandemic’s impact.

And remember, a decrease in the inflation figure doesn't mean mean prices will fall as well – it merely shows they are rising at a slightly slower rate.

As the table shows, no accounts can beat or equal the current rate of CPI inflation - however, according to Moneyfacts data, rates are still on the rise - particularly when it comes to instant-access accounts. 

The average rate for instant-access savings accounts hit 1.74% in February, up from 1.56% in January. These accounts offered an average of just 0.22% in February 2022.

Similarly, instant-access cash Isas are up to 1.85% this month, a rise of 0.19% since January (when they were at 1.66%), having risen from 0.26% this time last year. 

How does CPI inflation affect your savings?

CPI inflation is the speed at which the prices of the goods and services bought by households rise or fall. It tracks the costs of a shopping basket of around 700 popular goods and services bought by households – from tuna to train fares.  

The figure – which is provided by the ONS each month — shows how much prices have changed compared with the same month of the previous year. For example, if you'd bought all the same items in the basket in January 2022 and bought them all again the same month in 2023, you could expect your shop this year would be 10.1% more expensive.  

When you keep money in a savings account, you'll likely be earning interest, which should balance out the effects of inflation. If your cash isn't growing in interest at the same rate of inflation or more, it will effectively lose value because you'll be able to buy less with it. That's why you should ensure that your money is making the best return possible – even when savings rates are low.
