Ultimately, whether term deposits will work for you will depend on your particular financial needs.
Term deposits can be a great way to get your money working for you. By locking it away and forgetting about it for a period of time, it can earn interest for you. If you have the interest paid on a regular basis, rather than at maturity, you can either have some extra spending money or you can reinvest it into the term deposit to compound.
Of course, locking your money in a term deposit means you cannot access it for the length of the term, without paying a penalty for early withdrawal. This can remove the temptation to spend the money, while it also earns interest.
