Variable rate business savings accounts are typically easy access or notice varieties, and which one you choose will depend on your business needs. Easy access business savings accounts allow instant access to your funds in case of an emergency, whereas notice versions will require you to give notice to your provider (or result in loss of interest) before you can make a withdrawal, the trade-off being that you'll usually get a better interest rate – however, the keyword here is 'variable', which means providers can change the rate on both of these account types at any time.
They each have their benefits – easy access savings accounts allow you to get your hands on any surplus cash instantly, and you'll generally be able to make as many deposits and withdrawals as you'd like, with most having low minimum balances and few withdrawal restrictions. They don't pay the most competitive rates, but for flexibility, they can't be beaten.
Business notice accounts, on the other hand, come with a few more restrictions, with notice periods varying from seven days, but more commonly 30 days to 120 days. Some will allow you to access funds earlier, but there'll usually be a penalty, often in the form of reduced interest. That's why it's important to be truly organised with business notice accounts so you can give the notice period required, but for expenses such as tax bills – when you know the payment date and can plan your withdrawal accordingly – they could be ideal.
It's important to consider how much access your business might need to any saved funds before choosing an account, or you may want to split your deposits between several options to get the right mix of access and potential returns. You may even be focused on long-term growth and don't mind keeping a portion of business funds totally out of reach for a few years, in which case business bonds could be ideal.
