The average cost of payday loans and cash advances in America varies by state. Generally, you can expect to pay about $15 per $100 borrowed1. However, the fees for payday loans can range from $10 to $30 for every $100 borrowed2. On average, the APR works out to around 400%, with typical ranges from about 390% to 780%2. It is important to note that the fees and interest rates for payday loans are determined by a patchwork of state-level restrictions, and some states have no explicit interest caps at all3.
