It's always surprising for foreigners, specially from more financially savvy/developed countries, to see how expensive consumer credit actually is in Mexico. An average APR for credit cards (classic average ones) here would be around 60%. For instance, a large american bank that operates in Mexico (one of the largest here in terms of the market), has an average APR of almost 80% for its "Clasic" credit card. On the other side, "Platinum" credit cards for prime users do not generally go below 35-40% APR
