Concept
Temporal Price Framing
pricing framing
The same total price is judged more or less attractive depending on the time unit it's broken into — annual, weekly, or daily — even though the underlying cost is identical. Breaking a price down into its smallest natural unit (e.g. a daily figure) tends to make it look cheapest, because the number itself is smaller and easier to dismiss as trivial.
Richard Shotton tested this directly: the same cost presented as an annual, weekly, or daily figure was rated a "great deal" far more often when shown daily (see Shotton Payment Timeframe Framing Study). Anyone selling a product on a recurring payment plan (subscriptions, financing, insurance) has a direct incentive to use the smallest natural time unit available.
Rory Sutherland talked his own father into a Sky TV subscription he'd repeatedly refused (even when offered for free) purely by reframing the ~£17 monthly cost as "60p a day" and comparing it to money his father already spent daily on newspapers (see Sky TV Daily-Cost Reframing Case).
A cheaper-item replication (Episode 180): John Gourville's 2003 study found the same daily-framing lift applies even to inexpensive recurring costs like mobile phone contracts, not just big-ticket items like cars (see Goreville Daily-Framing Mobile-Contract Study).
The founding academic study, a unit-pricing extension, and a real-world BNPL application (Episode 270). Richard Shotton cites the original source directly for the first time: John Gourville's 1998 study found people were 53% more likely to agree to donate "$1 a day" than the mathematically identical "$365 a year" (see Gourville 1998 Pennies-a-Day Charity Founding Study). Shotton's own 2015 car-financing replication (see Shotton Payment Timeframe Framing Study) gets precise figures for the first time: only 11% rated the annual framing (£1,668) as good value, versus 51% for the daily framing (£4.57). A 2022 study extends the same logic to per-unit rather than per-time framing: a $18.99 12-pack of beer was rated good value more than twice as often when shown alongside its $1.58-per-bottle equivalent (see Shotton Aaron 2022 Sierra Nevada Per-Unit Pricing Study). Buy-now-pay-later service Klarna applies the identical principle commercially, splitting a purchase into several smaller installments to make the same total cost feel far more palatable (see Klarna Pennies-a-Day BNPL Case).
