Objective 6. Use Goal Seek

Goal Seek is a method to find a specific value for a cell by adjusting the value of one other cell. With Goal Seek, you can work backward from the desired outcome to find the input necessary to achieve your goal. If you have a result in mind, you can try different numbers in one of the cells used as an argument in the function until you get close to the answer you want.

Activity 3.13. Using Goal Seek to Produce the Desired Result

Darron knows that his budget cannot exceed $4,500 per month for the truck loan. The trucks meet the specifications necessary to do the job and Darron has found the best price. Now he has two optionsborrow less money and get fewer trucks, or extend the time to repay the loan. To find out how much can be borrowed for three years to stay within the budget, or how much to increase the repayment period, you will use the Goal Seek command.


Click cell B5. From the Tools menu, click Goal Seek. In the Set cell box, confirm that B5 is displayed.

The cell address in this box is the cell that displays the desired result.

Using the Future Value Function

Another commonly used financial function, similar to the PMT function, is the Future Value function. The function has three required arguments: Rate, Nper, and Pmt. The Rate argument is the interest rate paid to you by the financial institution; the Nper is the number of periods; and Pmt is the amount you deposit into the account each period. The function also has two optional argumentsPv and Type. The Pv argument is the amount you start with in the account. Excel assumes this is zero if you do not provide a starting amount. The Type argument assumes that the payment is made at the end of the time period.

Activity 3.14. Using Goal Seek to Find an Increased Period

For Darron's truck purchases, an alternative to borrowing less moneywhich would mean buying fewer truckswould be to increase the number of years of payments.
