A savings account isn't compulsory but it can be useful tool for managing your finances to achieve your goals. For example, if you would like to buy a house one day, a savings account can help you to reach this milestone as it encourages you to budget effectively and put money away each month. It's recommended that at least 20% of your income should be saved and a savings account is a safe place to store this money.
However, the biggest bonus of a savings account is that you also earn interest on your savings. In the past few years, interest rates on savings accounts have risen, but we're starting the see rates decrease now. There are many rates still above inflation and this gives your money more purchasing power. So, if your savings are currently sitting in an account earning little to no interest, then you could be missing out on some extra cash.
The savings account market is also always changing, especially when the Bank of England adjusts the base rate, so it's important to compare all savings accounts to find the best deal for your money.
