According to the results of a new survey of American consumers commissioned by Visa, intended to call consumers' attention to opportunities to save and budget in their discretionary spending, respondents report they spend an average of $53 a week or $2,746 per year on lunch. Overall, the most popular spot to eat lunch was home -- 42% of Americans said that they typically eat lunch at home. Full-time employees tended to stick close to the office -- 53% said that they typically eat lunch at work, including 26% at their desks.

Visa is also introducing the free Lunch Tracker app for iOS to help consumers become more aware of their spending. The app calculates the monthly and annual amount spent on lunch based off of consumers' input and seeks to help Americans improve spending habits. Users can take the 30-Day Challenge to start saving money, learn cost-cutting tips and share photos of meals with family and friends to show their progress.

"At home or ordering food, small choices have a big impact. Paying attention to what you are spending is essential to financial wellbeing," said Nat Sillin, global head of financial literacy at Visa Inc. "Most people may not realize that they are spending over $50 a week on lunch. Visa is excited to offer the new Lunch Tracker app to help consumers form better spending habits."

Visa's survey also showed that men both outspent women at the lunch counter and were more likely to eat lunch out. Males outspend females on a weekly basis by an average of 60%. One % of people reported spending more than $50 per lunch on average or more than $9,000 a year, while 32% respondents said that they didn't buy lunch out at all.
