The "No spend challenge" is a financial discipline where individuals commit to spending as little as possible for a month, often to save money or become more mindful of their expenses. This challenge has recently gained popularity among young people, especially in France. According to a study by Plum, a budgeting app, participants in the challenge can save an average of 293 euros in a single month. The survey, which included 1,000 young French adults between the ages of 18 and 34, found that 51% planned to take part in the challenge in September 2026. Men anticipated saving around 362 euros, while women expected to save approximately 234 euros. The No spend challenge is not meant to be a permanent lifestyle change but rather a short-term strategy to reduce unnecessary spending. Outside of the challenge, 90% of the surveyed individuals said they plan to save money every month in 2026. Their savings goals vary: 13% aim to save less than 50 euros per month, 27% target 50 to 100 euros, 25% want to save 100 to 200 euros, and 18% hope to save between 200 and 500 euros. Only 3% do not consider saving a priority, while 5% want to save but haven’t decided on an amount yet. The growing interest in the No spend challenge is partly due to the influence of social media and increased awareness of personal financial management. Similar challenges, such as "cash stuffing," where people physically stuff cash into a jar to avoid spending it, have also gained traction. Financial influencers and budgeting apps like Plum, Bankin', Linxo, and Finary have played a role in this trend by offering tools that help users track their spending and set savings goals. These apps often include features like daily spending limits and participation in structured saving challenges, making it easier for users to manage their finances. As more people seek ways to improve their financial habits, challenges like the No spend initiative are becoming a common way to start the conversation about saving and spending wisely.
