Please help! Sensitivity/What-if Analysis

[BullCity]

Hi All,

I'm looking to do a two-variable what-if sensitivity analysis, however, instead of just doing a simple sensitivity to a row cell and a column cell, I would like to shift an entire array as the column and row variables (see below).

The reason being that I have multiple "consumer products" (32 of them to be exact) and I'm trying to do a sensitivity analysis to all products at once to see the total aggregate impact, rather than building a what-if table for each product individually and then adding all 32 tables together.

To give a more clear example, array 1 might be cost of the product for each of the 32 products and array 2 might be quantity sold for each of the 32 products. I then have a cell that adds up all the revenue for all 32 individual products, which is what I want to run the sensitivity of price and quantity to.

I realized this may not be possible using the what-if tool in excel (I don't think you can do arrays).

Any ideas? Thanks in advance!

Hi shg,

Thanks for the input but I don't think that's quite what I'm looking for. The table what-if analysis only lets you vary a single cell at once for two different variables. I have two variables, but I need to vary many cells (basically an array). Did my example about consumer products make sense?

A varying single cell can select a secenario, which allows you to change 32 other variables. See Data Tables & Monte Carlo Simulations in Excel – A Comprehensive Guide | Chandoo.org - Learn Microsoft Excel Online
