FeeFlat 5% (4-week term)

Approval lift after removing bureau score

+38%

Approval experimentRemoving bureau scores from the model increased approvals by 38% without any increase in losses, suggesting the score was incorrectly rejecting creditworthy borrowers.1

Change in losses after removal

None

Credit qualityRemoving the bureau score did not increase loan losses, validating that Cash App's behavioral data model is at least as predictive as traditional credit scoring for this population.1
Stack integration
Cash App Card spending
Spending patternsCash App Card is a debit card linked to the user's balance. Spending patterns reveal financial behavior in ways a credit bureau cannot, including frequency, merchant categories, and cash flow consistency.
P2P transfers & deposits
Transfers and depositsPeer-to-peer transfers and direct deposits show income regularity and financial relationships. Regular inflows are a strong proxy for repayment capacity.
Square merchant purchases
Merchant dataPurchases at Square merchants give Cash App visibility into real-world spending behavior across Block's merchant network, adding another layer of behavioral signal.
Afterpay BNPL history
Buy now, pay laterAfterpay buy-now-pay-later repayment history is a strong signal for credit behavior. Consistent BNPL repayments indicate financial discipline not captured by traditional bureau scores.
Borrow repayment history
Repayment historyPast Borrow repayment behavior is the most direct signal. Borrowers who repaid previous loans on time are rewarded with higher limits and better terms.
Replaces bureau scores with a proprietary Cash App Score built from real-time behavioral data generated inside the platform
Proprietary scoringBlock launched a pilot in late 2025 giving users visibility into their own Cash App Score, the internal behavioral score that determines Borrow eligibility and limits. This signals Block's ambition to position its scoring model as an alternative to bureau scores, potentially offering it to other lenders as infrastructure.2
