For long-term savings, I'd suggest setting up a direct deposit into a high-interest savings account each month. This could be a specific amount agreed upon by the family and can help grow an emergency fund over time.
Another strategy is to put aside some of any money gifted or received as income - say, 10% - into a dedicated 'future fund'. This can really add up over time and provide a good base for future expenses or investments without impacting day-to-day finances too much.
You could also consider sharing some investment apps or platforms with the family. These can provide easy ways to grow savings over time, especially if you're looking for more significant long-term gains. Of course, there's always a risk involved with investments, so it's a personal choice, but many of these apps provide beginner-friendly options and resources to learn about investing.
A simple strategy that works well is having a goal amount in mind for the future fund and breaking it down into achievable monthly or annual targets. This provides a clear focus and helps make the most of incremental savings. For example, if you have a ten-year plan, break it down into months to see the progress and adjust as needed.
These strategies, combined with your existing methods, could help provide some solid financial security and an awareness of future funds without sacrificing too much fun in the present!
