If you need short-term funding, perhaps for a one-off purchase, you may want to consider a loan with a shorter-than-average repayment time. Short-term loans typically run for one year or less.
The interest rates associated with short-term loans are usually lower than those attached to credit cards or overdrafts; however, as the loan is intended to be cleared in a short period of time, you may find your monthly payments are higher than they would be with a credit card which has no defined end date. If you feel the payments may be too high for you to manage, you may want to consider a loan with a longer term, although this may mean you pay more overall over the life of the loan.
You will be charged interest on the entire amount of the loan as soon as the money is transferred to you. While this may work if you utilise the full amount immediately, if you intend to use the money to fund a series of purchases over a period of time, you may want to consider alternative options such as an overdraft where you will only be charged interest on the money once you spend it.
Short-term loans are offered by high street banks as well as specialist lenders, and it is always worth shopping around as rates vary considerably between providers. For the more competitive rates you will need to have a good credit history, and you may also be asked to provide a personal guarantee.
