The common feature among the spreadsheets templates is that they save time and effort and also they make the work and other calculations easier. Planning out things and fast access to data and other information are made very easy when using spreadsheet templates. But most of these templates are unique according to the purpose. The templates can be saved and used as many times as required.
Spreadsheet templates are used for many reasons and each template vary according to the purpose it is used for. Spreadsheets are designed with different calculations depending on various needs.
You could make money doing something you love (or like [or maybe not so much but just really good at]). It's great to see a spreadsheet come together, and usually a lot better than what you originally envisioned. Especially when the dang thing works.
Once you design the type of budgeting spreadsheets you want to use, it will be easy to copy it for subsequent months or years. You can also use just one sheet and create tabs for each month.
