How to use Solver in Excel with examples

Svetlana Cheusheva

The tutorial explains how to add and where to find Solver in different Excel versions, from 2016 to 2003. Step-by-step examples show how to use Excel Solver to find optimal solutions for linear programming and other kinds of problems.

Everyone knows that Microsoft Excel contains a lot of useful functions and powerful tools that can save you hours of calculations. But did you know that it also has a tool that can help you find optimal solutions for decision problems?

In this tutorial, we are going to cover all essential aspects of the Excel Solver add-in and provide a step-by-step guide on how to use it most effectively.

What is Excel Solver?

Excel Solver belongs to a special set of commands often referred to as What-if Analysis Tools. It is primarily purposed for simulation and optimization of various business and engineering models.

The Excel Solver add-in is especially useful for solving linear programming problems, aka linear optimization problems, and therefore is sometimes called a linear programming solver . Apart from that, it can handle smooth nonlinear and non-smooth problems. Please see Excel Solver algorithms for more details.

How to add Solver to Excel

The Solver add-in is included with all versions of Microsoft Excel beginning with 2003, but it is not enabled by default.

To add Solver to your Excel, perform the following steps:

  • In Excel 2010 - Excel 365, click File > Options . In Excel 2007, click the Microsoft Office button, and then click Excel Options .

Open the Excel Options dialog to get to the Excel Add-ins list.

To get Solver on Excel 2003 , go to the Tools menu, and click Add-Ins . In the Add-Ins available list, check the Solver Add-in box, and click OK .

Now that you know where to find Solver in Excel, open a new worksheet and let's get started!

How to use Solver in Excel

Before running the Excel Solver add-in, formulate the model you want to solve in a worksheet. In this example, let's find a solution for the following simple optimization problem.

Problem . Supposing, you are the owner of a beauty salon and you are planning on providing a new service to your clients. For this, you need to buy a new equipment that costs $40,000, which should be paid by instalments within 12 months.

Goal : Calculate the minimal cost per service that will let you pay for the new equipment within the specified timeframe.

A simple optimization model to solve

And now, let's see how Excel Solver can find a solution for this problem.

1. Run Excel Solver

2. define the problem.

The Solver Parameters window will open where you have to set up the 3 primary components:

  • Objective cell

Variable cells

Constraints.

Exactly what does Excel Solver do with the above parameters? It finds the optimal value (maximum, minimum or specified) for the formula in the Objective cell by changing the values in the Variable cells, and subject to limitations in the Constraints cells.

The Objective cell ( Target cell in earlier Excel versions) is the cell containing a formula that represents the objective, or goal, of the problem. The objective can be to maximize, minimize, or achieve some target value.

Setting the objective

Variable cells ( Changing cells or Adjustable cells in earlier versions) are cells that contain variable data that can be changed to achieve the objective. Excel Solver allows specifying up to 200 variable cells.

In this example, we have a couple of cells whose values can be changed:

  • Projected clients per month (B4) that should be less than or equal to 50; and
  • Cost per service (B5) that we want Excel Solver to calculate.

Specifying Variable cells

The Excel Solver Constrains are restrictions or limits of the possible solutions to the problem. To put it differently, constraints are the conditions that must be met.

To add a constraint(s), do the following:

  • Click the Add button right to the " Subject to the Constraints " box.

Adding a constraint

  • In the Constraint window, enter a constraint.
  • Click the Add button to add the constraint to the list.

Click the Add button to add the constraint to the list.

  • Continue entering other constraints.
  • After you have entered the final constraint, click OK to return to the main Solver Parameters window.

Excel Solver allows specifying the following relationships between the referenced cell and the constraint.

  • Less than or equal to , equal to , and greater than or equal to . You set these relationships by selecting a cell in the Cell Reference box, choosing one of the following signs: <= , =, or >= , and then typing a number, cell reference / cell name, or formula in the Constraint box (please see the above screenshot).
  • Integer . If the referenced cell must be an integer, select int , and the word integer will appear in the Constraint box.
  • Different values . If each cell in the referenced range must contain a different value, select dif , and the word AllDifferent will appear in the Constraint box.
  • Binary . If you want to limit a referenced cell either to 0 or 1, select bin , and the word binary will appear in the Constraint box.

To edit or delete an existing constraint do the following:

  • In the Solver Parameters dialog box, click the constraint.
  • To modify the selected constraint, click Change and make the changes you want.
  • To delete the constraint, click the Delete button.

In this example, the constraints are:

  • B3=40000 - cost of the new equipment is $40,000.
  • B4<=50 - the number of projected patients per month in under 50.

Excel Solver Constraints

3. Solve the problem

After you've configured all the parameters, click the Solve button at the bottom of the Solver Parameters window (see the screenshot above) and let the Excel Solver add-in find the optimal solution for your problem.

Depending on the model complexity, computer memory and processor speed, it may take a few seconds, a few minutes, or even a few hours.

The Solver Results dialog window

The Solver Result window will close and the solution will appear on the worksheet right away.

The solution for the problem is found.

  • If the Excel Solver has been processing a certain problem for too long, you can interrupt the process by pressing the Esc key. Excel will recalculate the worksheet with the last values found for the Variable cells.
  • To get more details about the solved problem, click a report type in the Reports box, and then click OK . The report will be created on a new worksheet:

Excel Solver Reports

Excel Solver examples

Below you will find two more examples of using the Excel Solver addin. First, we will find a solution for a well-known puzzle, and then solve a real-life linear programming problem.

Excel Solver example 1 (magic square)

I believe everyone is familiar with "magic square" puzzles where you have to put a set of numbers in a square so that all rows, columns and diagonals add up to a certain number.

For instance, do you know a solution for the 3x3 square containing numbers from 1 to 9 where each row, column and diagonal adds up to 15?

It's probably no big deal to solve this puzzle by trial and error, but I bet the Solver will find the solution faster. Our part of the job is to properly define the problem.

The magic square puzzle to solve

With all the formulas in place, run Solver and set up the following parameters:

  • Set Objective . In this example, we don't need to set any objective, so leave this box empty.
  • Variable Cells . We want to populate numbers in cells B2 to D4, so select the range B2:D4.
  • $B$2:$D$4 = AllDifferent - all of the Variable cells should contain different values.
  • $B$2:$D$4 = integer - all of the Variable cells should be integers.
  • $B$5:$D$5 = 15 - the sum of values in each column should equal 15.
  • $E$2:$E$4 = 15 - the sum of values in each row should equal 15.
  • $B$7:$B$8 = 15 - the sum of both diagonals should equal 15.

Set up the Excel Solver parameters.

Excel Solver example 2 (linear programming problem)

This is an example of a simple transportation optimization problem with a linear objective. More complex optimization models of this kind are used by many companies to save thousands of dollars each year.

Problem : You want to minimize the cost of shipping goods from 2 different warehouses to 4 different customers. Each warehouse has a limited supply and each customer has a certain demand.

Goal : Minimize the total shipping cost, not exceeding the quantity available at each warehouse, and meeting the demand of each customer.

Source data

Transportation optimization model

Formulating the model

To define our linear programming problem for the Excel Solver, let's answer the 3 main questions:

  • What decisions are to be made? We want to calculate the optimal quantity of goods to deliver to each customer from each warehouse. These are Variable cells (B7:E8).
  • What are the constraints? The supplies available at each warehouse (I7:I8) cannot be exceeded, and the quantity ordered by each customer (B10:E10) should be delivered. These are Constrained cells .
  • What is the goal? The minimal total cost of shipping. And this is our Objective cell (C12).

Formulating the model using Excel formulas

To make our transportation optimization model easier to understand, create the following named ranges:

Range name Cells Solver parameter
Products_shipped B7:E8 Variable cells
Available I7:I8 Constraint
Total_shipped G7:G8 Constraint
Ordered B10:E10 Constraint
Total_received B9:E9 Constraint
Shipping_cost C12 Objective

The last thing left for you to do is configure the Excel Solver parameters:

  • Objective: Shipping_cost set to Min
  • Variable cells: Products_shipped
  • Constraints: Total_received = Ordered and Total_shipped <= Available

Configure the Excel Solver parameters.

How to save and load Excel Solver scenarios

When solving a certain model, you may want to save your Variable cell values as a scenario that you can view or re-use later.

For example, when calculating the minimal service cost in the very first example discussed in this tutorial, you may want to try different numbers of projected clients per month and see how that affects the service cost. At that, you may want to save the most probable scenario you've already calculated and restore it at any moment.

Saving an Excel Solver scenario boils down to selecting a range of cells to save the data in. Loading a Solver model is just a matter of providing Excel with the range of cells where your model is saved. The detailed steps follow below.

Saving the model

To save the Excel Solver scenario, perform the following steps:

  • Open the worksheet with the calculated model and run the Excel Solver.

Saving the Excel Solver scenario

  • Excel will save your current model, which may look something similar to this:

The current Excel Solver scenario is saved.

Loading the saved model

When you decide to restore the saved scenario, do the following:

  • In the Solver Parameters window, click the Load/Save button.

Select the range of cells containing the saved model and click Load.

  • This will open the main Excel Solver window with the parameters of the previously saved model. All you need to do is to click the Solve button to re-calculate it.

Excel Solver algorithms

When defining a problem for the Excel Solver, you can choose one of the following methods in the Select a Solving Method dropdown box:

  • GRG Nonlinear. Generalized Reduced Gradient Nonlinear algorithm is used for problems that are smooth nonlinear, i.e. in which at least one of the constraints is a smooth nonlinear function of the decision variables. More details can be found here .
  • LP Simplex . The Simplex LP Solving method is based the Simplex algorithm created by an American mathematical scientist George Dantzig. It is used for solving so called Linear Programming problems - mathematical models whose requirements are characterized by linear relationships, i.e. consist of a single objective represented by a linear equation that must be maximized or minimized. For more information, please check out this page .
  • Evolutionary . It is used for non-smooth problems, which are the most difficult type of optimization problems to solve because some of the functions are non-smooth or even discontinuous, and therefore it's difficult to determine the direction in which a function is increasing or decreasing. For more information, please see this page .

This is how you can use Solver in Excel to find the best solutions for your decision problems. At the end of this post, you can download the sample workbook with all the examples discussed in this tutorial and reverse-engineer them for better understanding. I thank you for reading and hope to see you on our blog next week.

Define and solve a problem by using Solver

Solver is a Microsoft Excel add-in program you can use for what-if analysis. Use Solver to find an optimal (maximum or minimum) value for a formula in one cell — called the objective cell — subject to constraints, or limits, on the values of other formula cells on a worksheet. Solver works with a group of cells, called decision variables or simply variable cells that are used in computing the formulas in the objective and constraint cells. Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell.

Put simply, you can use Solver to determine the maximum or minimum value of one cell by changing other cells. For example, you can change the amount of your projected advertising budget and see the effect on your projected profit amount.

Example of a Solver evaluation

In the following example, the level of advertising in each quarter affects the number of units sold, indirectly determining the amount of sales revenue, the associated expenses, and the profit. Solver can change the quarterly budgets for advertising (decision variable cells B5:C5), up to a total budget constraint of $20,000 (cell F5), until the total profit (objective cell F7) reaches the maximum possible amount. The values in the variable cells are used to calculate the profit for each quarter, so they are related to the formula objective cell F7, =SUM (Q1 Profit:Q2 Profit).

1. Variable cells

2. Constrained cell

3. Objective cell

After Solver runs, the new values are as follows.

When you save a model, enter the reference for the first cell of a vertical range of empty cells in which you want to place the problem model. When you load a model, enter the reference for the entire range of cells that contains the problem model.

Tip:  You can save the last selections in the Solver Parameters dialog box with a worksheet by saving the workbook. Each worksheet in a workbook may have its own Solver selections, and all of them are saved. You can also define more than one problem for a worksheet by clicking Load/Save to save problems individually.

Solving methods used by Solver

You can choose any of the following three algorithms or solving methods in the Solver Parameters dialog box:

Generalized Reduced Gradient (GRG) Nonlinear     Use for problems that are smooth nonlinear.

LP Simplex     Use for problems that are linear.

Evolutionary     Use for problems that are non-smooth.

Important:  You should enable the Solver add-in first. For more information, see Load the Solver add-in .

In the following example, the level of advertising in each quarter affects the number of units sold, indirectly determining the amount of sales revenue, the associated expenses, and the profit. Solver can change the quarterly budgets for advertising (decision variable cells B5:C5), up to a total budget constraint of $20,000 (cell D5), until the total profit (objective cell D7) reaches the maximum possible amount. The values in the variable cells are used to calculate the profit for each quarter, so they are related to the formula objective cell D7, =SUM(Q1 Profit:Q2 Profit).

Tired of struggling with complex problems in Excel? Excel Solver can help.

This powerful tool makes finding the best solutions easy. Unlike Goal Seek or the What-If tool, Solver goes beyond simple scenarios, tackling more complex optimization problems.

In this blog post, you’ll learn how to use Excel Solver with a simple example. Discover how it saves you time and improves your results. Boost your productivity and make better decisions with Excel Solver.

Keep reading to see how this feature can transform your workflow!

Imagine you want to maximize your profit by adjusting prices and costs while keeping prices and costs within specific limits. Or, you need to allocate your remaining budget across multiple projects with certain spending constraints. Excel Solver can help you achieve these goals efficiently.

Excel Solver is a powerful tool in Microsoft Excel that helps you find the best solutions by adjusting multiple inputs. Use Solver in Excel to maximize or minimize outcomes like profit, cost, or efficiency.

Key Features of Excel Solver

  • Optimization : Solver helps you find the best values for your inputs to get the desired results. Increase profits, reduce costs, or meet specific targets easily.
  • Multiple Variables : Adjust several inputs at once, making Solver perfect for complex problems.
  • Constraints : Set limits for your inputs, such as keeping prices within a range or ensuring numbers are whole.
  • GRG Nonlinear: Best for nonlinear problems, finding a local best solution.
  • Simplex LP: Ideal for linear problems.
  • Evolutionary: Great for complex problems, finding a global best solution.

Often our students ask: Where is Solver in Excel?

Did you know the Microsoft Solver add-in is included with all versions of Excel since 2003, but it’s not enabled by default? Here’s how you can quickly activate it:

  • Open Excel: Start by opening your Excel application.
  • Go to File : Click on the “File” tab in the top left corner.
  • Select Options : Choose “Options” from the drop-down menu.
  • Choose Add-ins : In the Excel Options window, click on “Add-ins”.
  • Manage Add-ins : At the bottom of this window, find the “Manage” box. Select “Excel Add-ins” and click “Go”.

excel problem solving workbook

  • 6. Enable Solver : Check the box next to “Solver Add-in”.
  • 7. Confirm: Click “OK” to activate Solver.

excel problem solving workbook

Now, you can find Solver under the “Data” tab in the “Analyze” section.

How to Use Solver in Excel – Example

Goal Seek is great, but it only changes one input variable. For more complex problems with multiple variables, Solver is the tool you need.

Here’s a simple example:

You want to achieve a target income of 2,000 by adjusting the units sold and the price per unit.

excel problem solving workbook

  • Units Sold:  Input variable.
  • Price per Unit : Input variable.
  • Revenue : Calculated as Units Sold * Price per Unit
  • Cost per unit : A fixed number.
  • Total Costs : Calculated as Units Sold * Cost per Unit.
  • Income : Calculated as Revenue – Total Costs.

Constraints

  • Units sold must be a whole number.
  • Price per unit should be between 3 and 4.

Using Solver in Excel

When you open the Solver Parameters window, you need to set up three primary components: the objective cell, variable cells, and constraints. Here’s how to do it:

Set the Objective

Objective cell: This is the cell that contains the formula you want to optimize. For example, if you want to maximize profit or minimize costs, select the cell with that calculation.

In our example, the objective cell is $B$11, which calculates the income.

  • Go to the Data tab, find the Analyze section, and click Solver. Set the objective cell ($B$11) to a value of 2,000.

excel problem solving workbook

Select Variable Cells

These are the cells that Solver will change to achieve the objective. Highlight the cells you want to adjust.

  • For our example, these are the units sold and the price per unit, so we select $B$3:$B$4 and $B$8.

Add Constraints

Constraints are the limits you set for your variable cells. Click “Add” in the Solver Parameters window to specify these limits. For our example, set the units sold to be a whole number (integer) and the price per unit to be between 3 and 4.

  • Click “Add” to set limits. Specify that units sold must be an integer and the price per unit should be between 3 and 4.

excel problem solving workbook

  • Choose Solving Method: Select the appropriate solving method (e.g., GRG Nonlinear).

Click on Solve. The Solver Results window will pop up, saying that it has found a solution. You will notice that the values of the input cells have changed but the formulas in your calculated cells have been retained. You are given the option to accept the new values by clicking on OK, or reject them by clicking on Cancel.

Excel Solver offers three methods to find the best solution for your problem. Here’s a quick overview:

GRG Nonlinear

  • Best For: Nonlinear problems.
  • How It Works: Finds a local optimal solution.
  • Default Method: This is the most commonly used method and is set as the default.
  • Best For: Linear problems.
  • How It Works: Efficiently solves problems with linear relationships.

Evolutionary

  • Best For: Complex and non-smooth nonlinear problems.
  • How It Works: Searches for a global optimal solution, which can take longer to run compared to GRG Nonlinear.

Solver can be a powerful tool when you need to allocate a budget among multiple projects, especially with specific constraints. Here’s an example to illustrate how to use Solver for this purpose:

You need to distribute a budget across several projects, with the following constraints:

  • Extra costs should not exceed 1,000.
  • Fixed costs must remain at 2,000.
  • Total project cost for each project should not exceed 9,600.

excel problem solving workbook

Setting Up Solver

Set objective :.

  • Go to the “Data” tab, find the “Analyze” section, and click on “Solver”. Set the objective cell ($B$14) to a value of 65,000.

Select Variable Cells:

Highlight the cells that Solver can change:

  • Extra costs: $D$5:$D$13
  • Production costs: $B$5:$B$13 (we choose Production Cost instead of Total Costs because the latter is a calculated field).

Add Constraints:

Click “Add” in the Solver Parameters window to set the following constraints:

  • Extra costs ($D$5:$D$13) must be less than or equal to 1,000 ($E$18).
  • Total project cost ($E$5:$E$13) must be less than or equal to 9,600 ($E$20).

excel problem solving workbook

Solve: Choose the appropriate solving method (e.g., GRG Nonlinear) and click “Solve”. Solver will find the best solution, adjusting the input cells within the defined constraints.

excel problem solving workbook

  • Start Simple: Begin with straightforward scenarios and gradually add complexity.
  • Experiment: Try different settings and constraints to see how they affect the outcome.
