So if you want more flexibility, you might want to consider a high-interest savings account instead. If you decide to take out your money early, you may be charged a penalty fee or earn a reduced rate of interest. Given the interest rate is fixed for the term of the investment, you know in advance how much you will earn at the end of the term. When your term deposit matures at the end of the fixed term, you can either roll over all your invested money into a new term deposit – likely at a new interest rate – or you can withdraw some or all of the money.
