Young adults spend an average of €130 a month on coffee, sandwiches and impulse snacks, according to research by SNS bank. And one in three of 18 to 35-year-olds are concerned about how much they spend a month on treats, SNS said.

The figures come from a survey of over 1,000 Dutch adults, who were asked about their monthly spending patterns, the AD reported on Tuesday.

“Young adults are more likely to make an impulse buy and feel they are less in control of their spending than older people,” Florien Cramwinckel, who advises SNS on social impact issues, told the AD.

“Some of this is down to brain function, such as planning and thinking ahead. We can see this in the survey. The older people are, the less likely they are to think their spending is out of hand.”

The research shows that 44% of young adults make a small, impulsive buy at least once a week, but that drops to 24% for older adults.

Social media also plays a part, Cramwinckel said. “If you see a mate or an influencer enjoying a latte macchiato on a café terrace, you might be tempted to do so yourself. Some 41% of young adults admit that their impulse buys are influenced by what others do online.”
