She moved 50 units for $7,550, roughly $151 each. Her commission column is nothing exotic, though there are <a href=\"https:\/\/www.makeuseof.com\/excel-functions-feel-like-spreadsheet-wizard\/\" target=\"_blank\">functions that keep commission math readable across a whole sheet<\/a> once yours outgrows a single multiplication.<\/p>\n<p>The first question is about effort. I point Set cell at her commission, type 600 into To value, and let Excel change Units Sold. It settles near 79.5 units.<\/p>\n<p>That result is worth more than the arithmetic behind it. Sarah needs about 30 more units, which is a figure I can put in a message. &#8220;Sell more&#8221; is not. By hand, the same answer means dividing, adjusting, and starting again whenever the average price shifts.<\/p>\n<p>The second question is about the plan itself. Same target, but this time I let Excel change the commission rate instead. It lands near 0.0794, which is 7.9%. Nothing changed except which cell I allowed to move, and the question stopped being about how hard a rep works. It became a question about what the plan pays. That&#8217;s how the judgment lies in choosing which cell to change.<\/p>\n<div id=\"custom_block_19\" data-nosnippet>\n<p>Goal Seek writes its answer straight into the changing cell with no undo prompt.

If you push the target high enough, Excel hands back a units figure well past 44, the largest single order anywhere in my sheet. It reports that with the same confidence as a realistic number, and nothing warns you the plan is fiction.<\/p>\n<p>It also works on one cell at a time, so eight reps means eight separate runs.<\/p>\n<p>The third is approximation. Goal Seek iterates toward the target rather than solving it outright, stopping once it lands inside a tolerance set under <strong>File > Options > Formulas<\/strong>, where Maximum Iterations and Maximum Change live.

It moves several inputs at once, and respects rules you set, so splitting a $30,000 target across four regions while capping each near what it has historically closed is squarely its problem. There is a fuller account of <a href=\"https:\/\/www.makeuseof.com\/microsoft-excel-solver-instead-of-goal-seek\/\" target=\"_blank\">where Solver picks up what Goal Seek drops<\/a>.<\/p>\n<p>But the cost is assembly. Solver has to be enabled from the add-ins list before it appears on the Data tab, and every run needs an objective, variable cells, and constraints written out. For one input, that is a lot of work.<\/p>\n<p>Scenario Manager sits in the same menu and does something different. It stores named sets of input values and switches between them, so comparing 5%, 6%, and 7.5% commission rates side by side is exactly its job. It solves nothing, though. Every figure in a scenario is one you supplied.<\/p>\n<p>The distinction settles it for me. Scenario Manager answers what happens if&#8230; Solver answers what the best mix would be. Goal Seek answers what has to be true, and planning almost always asks the third one. When a second variable shows up, I move to Solver rather than forcing Goal Seek to fake it.<\/p>\n<h2 id=\"the-next-thing-i-want-to-solve-backwards\">\n                        The next thing I want to solve backwards<br \/>\n               <\/h2>\n<h3 id=\"anything-with-a-target-attached-is-fair-game\">\n            Anything with a target attached is fair game<br \/>\n    <\/h3>\n<p>Sales commission was the obvious place to start because the numbers were sitting there, but the pattern is broader. Any sheet where one number is fixed and another is negotiable qualifies, which covers most of what I plan.<\/p>\n<p>Freelance rates are next, working out the day rate that clears a monthly income without adding days to the week. Then discounts, finding the percentage that still leaves a margin standing. Then schedules, backing into the pace a deadline actually demands. Excel did not become more capable when I started working this way; rather, it started answering the question I was already asking.<\/p>\n<\/p><\/div>\n<p> Leigha Schewe<br \/><a href=\"https:\/\/www.makeuseof.com\/excel-works-backwards-from-the-answer-you-want\/\" class=\"button purchase\" rel=\"nofollow noopener\" target=\"_blank\">Read More<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published Aug 11, 2026, 10:30\u202fAM EDT Yasir is a Mechanical Engineer who writes about tech at MUO, covering Windows, Productivity, Security, and the Internet.
