All people need a savings account. It is common to use a savings account as a buffer saving. This is important in case of unexpected expenses or anything else. A buffer of 1-3 monthly salaries is usually recommended. However, if your buffer savings are in a regular bank account, you will not be paid anything. In that case, you should open a savings account with interest. Remember to choose a savings account without binding time if you’re going to use it as a buffer. Otherwise, you can’t use the money when needed.
