Inflation jumped to 2.1% in April 2019, according to the latest figures from the Office for National Statistics (ONS), mainly due to rising energy prices and airfares.
This is up from March and February, where inflation remained at 1.9%. In January, inflation dropped to 1.8% - its lowest point for two years.
While this means that popular goods and services are more expensive than last year, it will also have a knock-on effect on your cash savings. If your cash is earning less than 2.1% interest, you may see your nest egg lose value in real terms.
Which? reveals why it's important for your savings to grow faster than inflation, and which accounts can help you do it.

As the table shows, you'll have to lock your money away for at least a year in a top-rate fixed-term savings account to beat inflation. If you opt for a cash Isa, you'll have to put your money away for at least four years.
You should also bear in mind that every fixed-rate account here requires a minimum initial deposit of at least £1,000, which might not be a viable option for those with smaller savings pots.
If you're likely to need more flexibility with your savings, you could consider an instant-access account. This is the only category where savings and cash Isas are matched. Both require just £1 to open, and offer 1.5% AER. While this rate doesn't beat inflation, it at least gives you some form of return.
However, note that both top-rate accounts have a bonus rate. This means the Marcus by Goldman Sachs AER will fall to 1.35% after 12 months, and Coventry Building Society's Isa drops to 1.15% after 31 August 2020 . Once this happens, you may want to switch accounts if you're no longer earning a competitive rate.
While fixed-rate cash Isa rates are lagging behind savings accounts, don't let that put you off altogether.
have the advantage of being tax-free. Any interest your money earns will never count towards your , and therefore you'll never be liable to pay tax on it. For some, this benefit can outweigh what you lose in interest.
Having tax-free savings is particularly useful for high earners and those with significant savings, who are either likely to exceed their personal savings allowance, or who pay additional-rate tax and don't receive one.
The ONS found that the main factors behind the inflation uptick were price rises across many broad categories, particularly airfares, fuels and new cars. This was offset by price cuts across clothing and footwear.
The graph below shows how CPI inflation has changed since 2013, with figures sourced from the ONS.
The Bank of England aims to keep inflation as close to 2% as possible. Inflation has hovered around this benchmark in recent months, after peaking at 3.1% in November 2017. At that point in time, no savings or cash Isa accounts could beat the rate of inflation.
CPI inflation tracks the prices of around 700 goods and services within an imaginary shopping basket, to see whether they've become more or less expensive compared to the same point in the previous year.
Taking this month as an example, buying everything in the shopping basket would cost 2.1% more than it did in April 2018.
If your cash has grown by less than the rate of inflation for the last 12 months, it will have effectively lost value, as you'll be able to buy less with it.
In order to see your savings grow - or, at the very least, break even - you need to find an account that beats or matches the rate of inflation.
