Small Payments, Large Commitments: How Installment Framing Influences Consumer Financial Decisions

This paper examines the effect of installment price framing on consumer financial decisions. It poses the question of whether consumers perceive a product as more affordable if it's sold in installments instead of a lump sum. This paper does not collect primary data. It synthesizes published research and public data. All 10 empirical evidence records were coded for product, sample, frame, outcome, effect direction, and disclosure. The evidence supports the hypothesis. Seven of the 10 records found that lower periodic prices, deferred payments, or Buy Now Pay Later (BNPL) led to higher purchase intention, spending, or perceived affordability. Recent BNPL research has also revealed an increase in order sizes and that financial constraints are not as important. The results of disclosure are less predictable. While clear information can help to increase understanding, it does not always result in behavior change. The findings indicate that the design of digital checkout is not neutral. Small-payment framing can increase purchasing, while consumers may downplay the overall financial commitment. The findings display the total price, payment terms, fees, and risk of late payment next to the installment payment. Consumers need to learn to consider the total cost of the item before buying and decide if it is affordable.
