Building a CAGR calculator in Excel

We already know that Excel is an incredibly powerful and useful tool, even if perhaps it is pretty pesky to get the hang of! One useful consultancy function to build in Excel is a Compound Annual Growth Rate (CAGR) Calculator. This is the measure of growth on an investment over a period of time, a particularly useful thing to find out if the investment fluctuates over time.
