Data Tables & Goal Seeker

[johnyboy010]

Hi All,

First time poster here and looking for help on what I believe may lie with data tables / goal seek.

My spreadsheet currently has many formulas but can be simplified to: Margin = (Price - Costs) / Price

I am looking to answer a question:

‘What would my price have to be if costs changed by a, b & c% and my margin was fixed at Y?

The Costs variable could be:

• Labour costs
• Materials costs
• Exchange rates
• Wholesaler margin

What I visualise is a table:
- with each cost variable on the x axis
- each a,b,c on the y axis
- contents of the table being prices
- above the table the input margin Y

Goal seek works but it is not dynamic and also does not allow me to see all the X variables together.

Would you have any advice?

You can try to develop a table with every combination of a.b.c that you want. This could leave you with thousands of separate rows. Think of each row as a separate scenario. Then, look for automated goal seek VBA code (should be able to fine it on the board here), and adapt it to your model. The code will allow each scenario to be successively ran and then it will record your price (or whatever output(s) you want. I do this very thing where i need to back into a price made up of numerous variables (including required margin) and where I have hundreds of scenarios that I need to run at one time.
