What you need to know about the best cash ISAs
When choosing a cash ISA, there are two main factors to look out for: how long you are comfortable locking your cash up for and the interest rate.
- Easy access ISA accounts allow you to withdraw funds without incurring a penalty.
- Fixed-rate cash ISAs offer a fixed rate of return – usually higher the longer you are prepared to lock your money away. Note: if you withdraw money before the end of the term, then you are likely to be penalised, usually with a reduction in the rate of interest.
Generally speaking, the longer you leave the money untouched, the more interest you can earn. Many ISAs are classed as ‘flexible’, meaning you can replace any funds you withdraw in the same tax year without affecting your annual ISA allowance – which is currently £20,000.
We have an ISA guide to help you learn everything you need to know about how they work, how much you can pay in, what investments you can hold, and how to transfer one.
