A payday loan is a small, short term loan, typically a few hundred dollars due on your next payday, priced as a flat fee rather than interest. It is the most common legal product occupying the space where loan sharks once operated, and the honest description of it lives in the space between “legal” and “safe.”
How payday loans work
You write a postdated check or authorize a bank withdrawal for the amount borrowed plus a fee, usually $15 to $30 per $100 borrowed, and the lender funds you in cash or by deposit. Two weeks later the lender cashes the check or debits your account. On a two week term, a $15 fee per $100 works out to an annual percentage rate of roughly 400 percent.
The rollover cycle is the business model
The two week term is the trap’s mechanism. Most borrowers cannot spare the full repayment from one paycheck, so they pay another fee to roll the loan over, or repay it and immediately borrow again. Federal regulators studying the market have found that the large majority of payday loan volume comes from borrowers in long chains of consecutive loans, paying fees many times the original amount borrowed while the principal never shrinks. If that structure sounds familiar, it is the licensed cousin of the interest-only treadmill described in how loan sharks work.
Payday loans are not legal everywhere
State law decides. Some states prohibit payday lending or cap small loan rates around 36 percent, which effectively excludes the product. Others permit it with limits on fees, loan size, and rollovers, and several require lenders to offer extended payment plans at no extra cost. Check your state regulator’s site before assuming an offer is legal, because an unlicensed payday lender, common online, is not a payday lender at all. It is an illegal lender, with everything that implies: see loan sharks vs payday loans.
If you use one anyway
Sometimes a payday loan is genuinely the only legal option on the table. If so, borrow once and small, confirm the lender’s license, know the exact dollar total due, and have the repayment reserved before you borrow. Ask whether your state requires an extended payment plan option. What turns a payday loan from expensive into ruinous is the second one.
Cheaper ways to solve the same problem
Credit union payday alternative loans are capped at 28 percent, several large banks offer small dollar loans to checking customers at flat fees a fraction of payday pricing, and bill assistance through 211 can remove the need to borrow entirely. The full ranked list is in alternatives to loan sharks. If you are already in a payday cycle, a nonprofit credit counselor on our debt help page can often restructure it.
