Payday lenders are often bashed for charging more than 6,000% annual interest - despite loans being charged for short periods of time.
They are a high-interest loans that has been slammed for trapping people in debt.
What are payday loans?
Payday loans are designed as a last resort for those struggling with their next finances until the next payday.
But they come with massive rates of interest - sometimes up to 6,000%.
If you borrowed £200 from the Uk's biggest payday lender, Wonga (who charge 5,853% APR), for 24 days - you would have pay back £254.82.
Why is the industry/media so worried about people using them?
Payday loan companies been heavily slammed by the media, government, charities and even the head of the Church of England over their high interest
Charities have also accused payday lenders of pushing customers into a spiral of debt because of the way they operate - some let people roll over loans, increasing the amount they owe, a number of times.
They also say that people who borrow from payday loan companies end up taking out loans from multiple lenders because they cant afford to pay them off.
What should you use a payday loan for?
As an absolute last resort. For example, you've run out of money and your car needs to be repaired in order for you to get to work.
Wonga's co-founder Errol Damelin once told ITV news: 'This is not about people on breadlines being desperate...this is about us serving customers who want to take a loan and know they can pay it back in 3 days - that is in the same way that they want to buy one song on iTunes.'
We tend to disagree. Borrowing money is not the same as buying one song on iTunes.
You should never use a payday loan for nights out, concert or sport tickets, new clothes or treats, such as a new album.
The Money Advice Service says in its guide to payday loans, 'In reality, all you're doing is paying a small fortune to borrow money for something you can't afford.'
