Payday loans are usually small amounts of cash borrowed for relatively short periods of time. Thy carry high risk from a lender point of view and are priced accordingly.
Always remember that payday loans are an expensive form of credit and should not be used repetitively. They are only meant to cover short term cash emergencies.
Most people see the APR figures which can be very intimidating. The APR usually represents 0.8% per day which is the legal cap. If borrowed for short periods it can be less intimidating.
High cost short term credit is also capped at 100% of the amount borrowed. If you borrow 100 your charges and fees will never exceed 100.
