Continuing with our Excel Tutorials, in this article, I’ll take you through using Goal Seek in Microsoft Excel 2007. The function is same as that of earlier versions of Excel as well as Excel 2010. The screenshots below are taken in 2007.

In my last Excel Tutorial, I covered using SUMIFS and SUMPRODUCT.
Data Tables is also an advanced topic in Microsoft Excel that falls under the category of What-If Analysis. What-If or Sensitivity Analysis is carried out to study the variation of the output to changes in the input variable.
Consider a case of compound interest, where you invest a certain amount of money in a bank deposit and the amount is compounded every year.
Formula for calculating compound interest:
A = P * (1 + r/n) ^ nt
Where:
Now, if suppose we want to see what the final amount will be at different interests rates, we can quickly use a data table for the same.
The title of the post is a bit of a misnomer because the SUMIF function in Excel does not allow you to have more than condition.
Excel 2007 introduced the SUMIFS function which allowed for multiple conditions. However, if you are using any version prior to Excel 2007 or if the persons who will be using your Excel workbook will be using a version prior to Excel 2007, then the SUMIF function will throw up an error.
That is a problem a colleague faced at work. To solve this problem you can use SUMPRODUCT along with double negation. The double negation is simply two minus signs one after an another. The net effect is that it doesn’t change the value of the calculations.
The reason we use the double negation is because, Excel does not always understand that TRUE=1 and FALSE=0 when you use SUM or SUMPRODUCT.
