Overdraft interest rates are sometimes outrageously high: These alternatives will save you a lot of money. Some banks charge no overdraft interest, others charge over 17 percent.

Depending on the bank, the overdraft can be really expensive - but there are cheaper alternatives. Take out a line of credit or take out an installment loan, as you have to pay significantly lower interest rates. Ask family or friends to lend you money, as long as it is within a certain limit. You will be doubly motivated to pay back the money you borrowed as quickly as possible.
