Goal Seek

It determines the value that you need to enter in a single input cell to produce the result that you want in a dependent (formula) cell. The following example shows you how single-cell goal-seeking works.

The figure above is showing an investment of Rs 1,200 per month @9.5% rate of interest for 5 years can yield a future value of Rs 91,706.70.
Now the problem with the investor is to get Rs 150000 after the 5 years span. Now he/she wants to know how much should be invested to get that much of an amount. This can be solved through the Goal Seek option of the excel what-if-analysis tool. Following are the steps to be followed:
- Place your cursor on cell B4. Choose Data -> Data Tools -> What-If Analysis -> Goal Seek. Excel displays the Goal Seek dialog box, shown in the Figure below.

Set cell B4: the cell you where to want to set the value. Set value 150000 To value field. Changing cell field should contain the address of the cell you want to change [B1]; i.e, the monthly premium.
2. The following information box will appear.
