Keep in mind that the Solver is an add-in utility. The first step in setting up a problem for the Solver to work on is to create the worksheet model for which you will define the objective cell, variables cells, and the constraint cells. Setting up and defining the problem in Excel 2019 Also, you can save the Solver’s solution to a problem as a scenario (by clicking the Save Scenario button in the Solver dialog box) that you can then view with the Scenario Manager. The changing cells that you define for the Scenario Manager are automatically picked up and used by the Solver when you select this command, and vice versa.
You can use the Solver add-in with the Scenario Manager to help set up a problem to solve or to save a solution so that you can view it at a later date. You can also save the solution as a scenario to view later before you restore the original values. At this point, you can choose to retain the changes in the worksheet or restore the original values to the worksheet. Constraint cells: The cells that contain the limits that you impose on the changing values in the variable cells and/or the target cell in the objective cell.Īfter you finish defining the problem with these parameters and have the Solver add-in solve the problem, the program returns the optimum solution by modifying the values in your worksheet.Variable cells: The changing cells in your worksheet whose values are to be adjusted until the answer is found.Note that this cell must contain a formula. Objective cell: The target cell in your worksheet whose value is to be maximized, minimized, or made to reach a particular value.When setting up the problem for the Solver add-in in your Excel worksheet, define the following items: To be sure that you are finding the best solution, you may want to run the Solver more than once, adjusting the initial values each time you solve the problem. Although the Solver returns the optimum solution, given the starting values, the variables that can change, and the constraints that you define, this solution is often not the only one possible and, in fact, may not be the best solution for you. When using the Solver add-in, keep in mind that many problems, especially the more complicated ones, have many solutions. With each iteration, the program applies a trial-and-error method (based on the use of linear or nonlinear equations and inequalities) that attempts to get closer to the optimum solution. The Solver add-in works by applying iterative methods to find the “best” solution given the inputs, desired solution, and the constraints that you impose.
How To Get Solver On Excel A modelling tool that we think improves on the built-in Solver window OpenSolver has been developed for Excel 2007/2010/2013/2016 (including the 64bit versions) running on Windows, and supports Excel for Mac 2011 on Mac OS X, with limited support for Excel for Mac 2016.

In Excel for Macintosh, if you don't see the Solver command on the Tools menu, you need to load the Solver add-in. Now on the Data tab, in the Analysis group, you should see the Solver command.
For example, use the Solver to find the best solution when you need to change multiple input values in your Excel model and you need to impose constraints on these values and/or the output value. How To Download Solver On Excel Mac AppĪlthough Excel’s Data Table and Goal Seek commands work just fine for simple problems that require determining the direct relationship between the inputs and results in a formula, you need to use the Solver add-in when dealing with more complex problems.
