Notes: This figure shows the estimated annual BNPL company issuance by loan type and cost. Virtually all "pay in 4" loans in panel (a) are interest-free and fall into the 0% APR category in panel (b), but some of the short- and longer-term installment loans in panel (a) are APR-bearing and some are 0% APR loans in panel (b), leading to the discrepancy in the levels between the two figures. Key identifies series in order from bottom to top.

Source: The "pay in 4" values for 2019 through 2023 are retrieved from a CFPB report (PDF). The "pay in 4" estimates for 2024 and 2025 and the short- and longer-term installment loan estimates are based on authors' calculations using information either directly retrieved or derived from the sources detailed in Table 1.
