More than half (51%) of people admit to spending more than they need to for products and services because they are not willing to wait.
Ordering takeaways, upgrading postage for a speedier delivery and taking a taxi instead of waiting for a bus or train were common ways for people to regularly spend extra, according to the Financial Services Compensation Scheme (FSCS), which protects savers' cash when financial firms go bust.
Based on the findings, the FSCS estimates that some people are paying as much as £2,000 extra a year because they prefer not to wait.
People aged between 25 and 34 are the most likely to spend more to reduce waiting times, with nearly three-quarters (72%) saying this.
More than nine in 10 (92%) people surveyed think society generally is becoming more impatient - with technology and busier lifestyles given as popular reasons for people wanting goods and services faster.
More than 2,000 people took part in the survey for the FSCS, which has produced some "money means" guides to help people save.
