Lenders set interest rates in two ways. Product-driven pricing, or a risk-based rate for each customer.
Product-driven pricing gives every customer the same rate for a given product. You can estimate product profitability as the average expected risk cost per loan in that portfolio.
Risk-based pricing sets a rate for each customer based on the probability of default.
This approach lets you differentiate rates to improve profitability and remain competitive. It is harder to execute because you need to understand each customer's risk.
Risk-Adjusted Return on Capital
Some lenders calculate Risk-Adjusted Return on Capital (RAROC) for each customer and set the rate from that result. RAROC can also include customer lifetime value, including potential cross-sell and upsell.
Risk-based pricing is complex because the formulas used to calculate RAROC can change and may include multiple models.
The models used in RAROC can include
- Anti-fraud model: the probability of fraud
- Credit risk model: the probability of credit risk
- Cross-sell and upsell propensity model: the probability of accepting an offer
Complexity also comes from different customer segmentation by demographics.
In practice, full risk-based pricing can sit as a sub-flow within the underwriting decision flow.

Credit risk strategy in micro-lending
Micro-lenders face specific credit risks that demand a focused, operational strategy to cut default probability and improve repayment. This article defines four core risk groups (business, country, sector, borrower) and lays out practical controls: structured credit analysis, personal guarantees and collateral, LTV and term limits, risk-based pricing, portfolio reviews, provisioning, collections, and selective use of alternative data. It also shows how to encode these policies as auditable decision logic.

Why BNPL Changes the Economics of Consumer Finance
Consumer finance has always depended on a simple idea: lend against something that creates value or preserves access to value. Buy now, pay later changes that model. It combines parts of installment lending, revolving credit, and merchant finance, but it also changes the risk profile, the economics, and the operating model.
This article looks at consumer finance through the lens of business model design, credit risk, fraud risk, portfolio risk, operational risk, and return on capital.
