We determined the total expense of a standard payday loan ($300 amount, 14-day duration, single payment) by using original data from each state's financial regulator, the CFPB enforcement records, the OCC's reports on small-dollar lending, and statistics from the NCUA's PAL program.

When a state's legal rate limit is set below what payday lenders need to operate profitably (approximately 36% APR or lower), we classify it as "effectively banned" and confirm this by reviewing the regulator's list of licensed lenders. Loans from out-of-state companies offered to residents at higher rates are generally unenforceable in the courts of those states.

For states that have "no cap" (Idaho, Utah, Wisconsin, Texas-via-CAB, Nevada, Delaware), we applied average market rates from OLA disclosures and market research by The Pew Charitable Trusts. These numbers show the usual storefront average; costs from different lenders can vary significantly.

The quoted "national average" of $16.66 per $100 for a 14-day term is weighted by population and calculated only across states where payday lending is legal (listed as "allowed" or "restricted" in our data). Populations in banned states (90.7 million, about 27.1%) are tallied separately.
