How to Calculate Average Growth Rate in Excel

Enter and format the column heading for the average growth rate calculator. Type "Future Value" into cell B1. With cell B1 still selected, click the "Wrap text" button on the formatting tool bar. Select the "Formatting brush" from the formatting toolbar and drag the formatting brush from cell C1 through cell F1.

Format the cell borders for the average growth rate calculator. Click in cell B1, and drag to select cells B1 through F1. On the formatting toolbar, click the arrow on the Borders button and select "Thick bottom borders." Click and drag to select cells B2 through F2. On the formatting toolbar, click the arrow on the Borders button and select "Outside borders" from the menu options. The cells in the average growth rate calculator will now be outlined in black.

Enter the formula for calculating the annualized yield rate. Type the following formula into cell F2: =((B2/C2)^(1/D2))^E2-1. The average growth rate of an investment will now appear in cell F2 whenever values are entered into cells B2 through E2.

Enter the following values into cells B2 through E2 to test the accuracy of the average growth rate calculator. Type "100,000" in cell B2, "500" in cell C2, "120" in cell D2 and "4" in cell E2. If the resulting figure in cell F2 is "19.32%," the calculator is functioning properly. In other words, if an investment of $500 dollars yields $10,000, over a period of 10 years (120 months), where the interest is paid quarterly, the average growth rate is 19.32%.
