The Growth Rate Margin measures the difference between the Sustainable Growth Rate % and the Actual Sales Growth Rate %. 

 When sustainable growth is less than actual growth over a protracted period, the company cannot sustain such activity without funding that growth. Either they need to: 

1. Retain more profits
2. Increase the net profit margin or turnover performance
3. Fund from other sources, by increasing debt levels 

When sustainable growth is greater than actual growth, the company has the potential to increase growth. If they consistently fall below sustainable growth, they may be underperforming.

Formula: 

Growth Rate Margin = Sustainable Growth Rate % - Actual Sales Growth Rate %
