I&#x27;m looking for some help with growth rates. I&#x27;m trying to calculate the monthly growth rate for my app. Over the last year we went from 300,000 to 1,200,000 total user sessions. However, on a monthly basis, we had approximately 75,000 sessions completed, and it stayed consistent throughout the year. While on one hand we&#x27;ve quadrupled our total usage, on the other hand our growth has remained flat each month. The key question here is this - when we talk about  monthly growth, are we normally talking about cumulative usage or monthly increase in usage?<p>Based on the “rule of 72” it seems that quadrupling over the course of a year corresponds with a 12% monthly growth rate.<p>source: http:&#x2F;&#x2F;daslee.me&#x2F;monthly-growth-and-the-rule-of-72<p>On the other hand, each month our usage stayed flat - 75,000 sessions were completed each month. From one perspective, we had 0% growth, as each month our numbers were the same. However, from the perspective of one year, we quadrupled the total number of sessions.<p>Is our monthly growth 0% or 12%?<p>Any feedback on this would be helpful. Thanks!
