Goal Seek in Microsoft Excel

 

 

Excel includes several tools for data analysis and Goal Seek is a technique used to easily find the number that fulfills the necessary conditions to achieve a goal.
 

This tool will help you do many tests of values in a formula to find the exact value that meets the conditions. That is, if we know the result of a formula, but we are not sure of the value of one of its arguments, then Goal Seek will help us to test various scenarios to find the exact value needed. For example, suppose we have the following problem.
 
Goal Seek Initial Data
 
I have a number multiplied by another number X and this should give me the result shown. Although this is an easy problem to solve mathematically will be useful to show the functionality of Goal Seek. I begin by defining an important formula. In cell C3 will place the formula to be met to obtain the desired result, ie, = B1 * B2 it should result in 689

For now the result in C3 is zero, because there is no value in cell B2, however, when you go looking for the appropriate value for B2, the value of cell C3 will become the same as B3 when the correct value is found.
