A new study by Swiss bank Bank Cler has quantified the impact of price psychology on consumer tipping behavior in the restaurant industry.
The research found that customers are significantly more likely to leave higher gratuities when menu prices end in figures that require rounding up, rather than rounding down.
According to the findings, a cappuccino priced at CHF 5.10 generates an average tip that is 30 cents higher than the same beverage priced at CHF 4.90.
The study suggests that the cognitive friction of rounding up a price encourages customers to leave a larger tip to compensate for the perceived inconvenience, whereas rounding down often leads to smaller or no gratuities.
This behavioral insight offers a strategic lever for restaurant operators seeking to improve staff compensation without raising base wages or altering menu structures significantly.
By adjusting prices to end in higher cent values, establishments can potentially increase total revenue through enhanced tipping patterns.
