Spending in the pubs and bars in the Wimbledon area increases by 48% during the tennis tournament compared with the previous fortnight, according to a new study.
Payment processing firm Worldpay calculated the figures using the average value and volume of transactions during the 2013 Championships.
Taking into account the five surrounding London postcodes, the study also found that restaurants receive 21% more orders on weekdays during Wimbledon.
Total spend across the retail and hospitality sectors is estimated to rise by as much as 13%.
Dave Hobday, managing director of Worldpay UK, said: "It's game, set and match for local pubs and bars, which are set to see the biggest financial impact from the tournament as average spend ups by almost 50%.
"This is superb news for those who missed out on the feel-good windfall we expected from the World Cup."
