When emergencies arise, you might not have enough money to pay for what you need. Installment loans are a solution for those who need to borrow money but can't pay back all of the amount at one time.
With this kind of Installment loans, you will have a longer amount of time to pay back the loan. The terms are often more flexible than with another loan that you might get that has a set interest rate or mandated payments that you have to make each month.
There will be payments that you need to make every month, but you can usually set a term that you can handle like 12 months instead of six. Some of these loans have higher interest rates because they are easier to get, but they are usually less than the payday loans that you will probably find are difficult to pay back.
A loan like this through a bank is often much more manageable than one through a financing company. If you make the payments on time, then you can improve your credit score with most of these loans. Find out before taking the loan because some companies will say they report to credit agencies and end up not reporting anything unless you are late with a payment.
