Thumbs up Answer: Excel Chart Trendlines and percentages of increase or decrease

Yes, you can easily get the exact percentage of the overall trend rate when you trend data via Excel. Here are the steps to follow:
  1. First, create a chart in Excel with the data you want to trend.
  2. Next, add a trendline to the chart by right-clicking on one of the data points and selecting "Add Trendline."
  3. In the "Format Trendline" pane that appears on the right-hand side of the screen, select the "Trendline Options" tab.
  4. Under "Trendline Options," select the "Display Equation on chart" checkbox.
  5. The equation for the trendline will now appear on the chart. The equation will be in the form y = mx + b, where m is the slope of the trendline.
  6. To calculate the percentage increase or decrease of the trend rate, you need to divide the slope of the trendline by the initial value of the data and then multiply by 100.
  7. For example, if the equation for the trendline is y = 0.5x + 10 and the initial value of the data is 100, the percentage increase of the trend rate would be (0.5/100) x 100 = 0.5%.

That's it! You now know how to get the exact percentage of the overall trend rate when you trend data via Excel.
