As previously discussed, there are pros and cons of payday loans. If you're hoping to benefit from these resources, however, there is one important rule to live by:

• NEVER rollover a payday loan.

By constantly delaying the deadline by which they must pay back the amount borrowed, consumers allow interest rates to severely add up. This is what leads to such mounting debt and why many people are against payday loans.

If you need to repair your car or home; pay rent; pare down credit card balances; or deal with any other kind of financial crisis, a cash loan could be the fastest way to obtain the money you need. But keep the time period in mind within which lenders want to see their paycheck advance returned. Typically, this is a two-week window.

After that has expired, you're always allowed to extend the repayment - but at an extremely high APR. This is known as a "rollover." The more times you rollover your payday loan, the more you'll end up falling into a new kind of debt. Just keep this in mind, however, and the occasional borrowing may pay off down the line.
