## Summing with Subtotals and Grand Totals

You frequently need to organize the data in an Excel worksheet by one or more criteria. For example, you might have a worksheet in which you list yearly sales for each product you offer, with the products broken down by category. If your data is organized this way, you can have Excel calculate a subtotal for each category of products. When you create a subtotal, you identify the cells with the values to be calculated and the cells that identify the change from one category to the next; Excel updates the subtotal and grand total for you if the value of any cell changes.
