CAT (Costo Anual Total)
Mexico's standardized annualized cost indicator for consumer credit.
CAT is Mexico's mandated measure of the total annualized cost of credit, defined by Banco de México and enforced by CONDUSEF. For short fintech microloans, the standard methodology multiplies the declared daily rate by 365, commonly producing reference CAT figures around 365% across active Mexican lenders.
This reflects the mathematics of annualizing a short daily rate rather than necessarily an unusually expensive loan in peso terms — always compare the total pesos repayable for your specific amount and term alongside the CAT.
