How to Use Goal Seek to Calculate Salary Increases in Excel
Question details
The user wants to find out what percentage raise corresponds to a specific total budget increase using Goal Seek.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Calculating budget impacts when planning uniform salary increases across a team or company to hit an exact budget target.
- Observed behavior
- Needing a way to back-solve for a single variable (raise percentage) to achieve a desired output (target total budget increase) instead of relying on manual trial and error.
Ensure that your total salary budget cell contains a formula that directly links to the single cell holding the raise percentage. Goal Seek requires the target cell to be formula-driven and the changing cell to be a static numerical value.
Use What-If Analysis Goal Seek
Use the built-in Goal Seek tool to automatically find the correct raise percentage for your target budget.
Goal Seek is a powerful What-If Analysis tool that calculates backwards. You tell it the result you want a formula to produce, and it alters an input variable until the formula returns your desired result.
Ensure you have a cell for the current total salary (e.g., $11,289,461.73), an empty or static cell for the raise percentage (e.g., start with 0%), and a cell that calculates the new total salary or total increase using a formula linked to the raise percentage cell.
Navigate to the Data tab on your ribbon interface, click on the What-If Analysis dropdown button, and select Goal Seek.
In the dialog box, set 'Set cell' to your new total salary calculation cell. Set 'To value' to your target total budget (or target increase amount). Set 'By changing cell' to your raise percentage cell.
Click OK. Goal Seek will iterate through values and find the approximate required raise (e.g., 6.64%) to reach your exact target budget.
Calculate the Percentage Manually with a Basic Formula
If you only need a quick percentage without setting up a complex dynamic model, you can use basic division.

Frequently Asked Questions
Why is Goal Seek giving me an error that the cell must contain a formula?
Goal Seek works by changing an input value to see how it affects a formula's mathematical output. The cell you select in the 'Set cell' box must contain a valid formula that is directly or indirectly linked to the cell you specify in the 'By changing cell' box.
Can Goal Seek change multiple cells at once to find a salary budget?
No, Goal Seek can only change one single variable cell at a time. If you need to adjust multiple variables simultaneously (like calculating different raise percentages for different departments to meet one total budget), you should use the Solver add-in.
Why isn't Goal Seek finding an exact match for my target value?
Goal Seek uses an iterative calculation method that stops when it gets sufficiently close to the target value or after a maximum number of iterations. You can increase the precision by going to Options > Formulas > Calculation options and lowering the Maximum Change value.
