Previously on The Bottom line I showed you how to begin writing some basic formulas using the example of a sales tax computation. I left you with a cliff hanger though because there was an assumption that was operative in the example that might not be realistic in terms of a real life application of this. Specifically the model we set up assumed that every item in our list was taxable. This might work for most retail situations, but what about a contractor who might be invoicing for taxable materials as well as non-taxable labor. In the exciting conclusion to MS Excel Tutorial -- Basic Formula Writing Techniques, I show you how we can take this model a step further and identify taxable items vs. non-taxable while still having sales taxes calculate accurately. The challenge is in the formula that calculates the sales tax. We need a way to tell Excel to add items only if they are marked as taxable and then take that total and apply the sales tax rate. Of course this is easy to do manually by sorting the items and grouping the items but who wants to do that? I want to simply be able to go in and mark as taxable any items that are and have excel do the rest of the work for me!
Thank you for this guide.
