It varies from user to user, but it can be divided into dozens of subdivisions, or it can be classified into 10-20 if it is comprehensive. Whooing believes that 10-20 items per account are appropriate. In other words, the scope of the items should be grouped as close as possible into a comprehensive and large concept. You may want to subdivide something, but the subdivision is handled by [item].
The advantage of having a comprehensive range is that it can withstand frequent fluctuations. If it is subdivided into'desserts, dairy products, cafes', it is often affected by changes such as not eating dairy products in the future. It is a little better if you use larger concepts such as'snack' and'stock'. However, this can also become an aemul complex in which you will not eat'snack' in the future. It can be said that it is a comprehensive and stable item setting because you can't stop eating it anyway if you put all of these together and make one'food expenses' as an item.
