The formula for calculating CAGR is:. The CAGR calculation assumes that growth is steady over a specified period of time. CAGR is a widely used metric due to its simplicity and flexibility, and many firms will use it to report and forecast earnings growth. Financial theory suggests that a company's shares can be fairly valued using a dividend discount model DDM , based on the hypothesis that present-day price is worth the sum of all of its future dividend payments when discounted back to their present value.
As a result, dividend growth rates are important for valuing stocks. The Gordon Growth Model GGM is a popular approach used to determine the intrinsic value of a stock based on a future series of dividends that grow at a constant rate.
This dividend growth rate is assumed to be positive as mature companies seek to increase the dividends paid to their investors on a regular basis. Knowing the dividend growth rate is thus a key input for stock valuation. Growth rates are utilized by analysts, investors, and a company's management to assess a firm's growth periodically and make predictions about future performance.
Most often, growth rates are calculated for a firm's earnings, sales, or cash flows, but investors also look at growth rates for other metrics, such as price-to-earnings ratios or book value, among others.
When public companies report quarterly earnings, the headline figures are typically earnings and revenue, along with the growth rates—quarter over quarter or year over year—for each. The internal growth rate IGR is a specific type of growth rate used to measure an investment's or project's return or a company's performance. It is the highest level of growth achievable for a business without obtaining outside financing, and a firm's maximum internal growth rate is the level of business operations that can continue to fund and grow the company.
Because stock prices are thought to reflect the discounted value of a firm's future cash flows, a rising stock market implies improving forecasted growth rates for the company. Specific industries also have growth rates. Each industry has a unique benchmark number for rates of growth against which its performance is measured. For instance, companies on the cutting edge of technology are more likely to have higher annual rates of growth compared to a mature industry such as retail.
Industry growth rates can be used as a point of comparison for firms seeking to gauge their performance relative to their peers. The use of historical growth rates is one of the simplest methods of estimating the future growth of an industry. However, historically high growth rates do not always indicate a high rate of growth looking into the future as industrial and economic conditions change constantly and are often cyclical. For example, the auto industry has higher rates of revenue growth during periods of economic expansion, but in times of recession, consumers are more inclined to be frugal and not spend disposable income on a new car.
In addition to GDP growth, retail sales growth is another important growth rate for an economy because it can be representative of consumer confidence and customer spending habits.
When the economy is doing well and people are confident, they increase spending, which is reflected in retail sales. When the economy is in a recession, people reduce spending, and retail sales decline. For example, Q2 retail sales growth for Ireland was reported in July , revealing that domestic retail sales flatlined through the second quarter of the year.
It is believed that political instability within the country, combined with the results of the Brexit vote in June , caused Ireland's sales to stall. While some industries, such as agriculture and garden, showed positive growth, other industries within the retail sector counteracted that growth.
Fashion and footwear had negative growth for the quarter. Company growth can be measured along several dimensions, but all will follow the same basic approach, which is taking the difference between the current and former level and dividing that amount by the former level. Thus, we can judge a company's profit growth by comparing its bottom line in the current period versus the prior one. Analysts also consider sales revenue growth, stock price appreciation, and dividend growth in a similar manner.
Since growth rate calculations follow a fairly straightforward formula, they can be easily transported into a spreadsheet program like MS Excel in order to speed up calculations and remove the chance of human error. How much revenue will we earn from our current client base over the next time frame? This could be calculated by month, quarter, or year. Outside of the SaaS model, for any type of company looking for venture capital or angel investment, some overlapping metrics rely on or compliment MoM growth calculations.
Month-over-month growth can also be used to quantify team growth and staffing, for example by companies trying to decide if their staffing matches their ticket or customer growth. Companies commonly move to staff augmentation or similar scaled hiring practices in reaction to rapid changes in Month-over-Month growth rate. Again, even if your business is not dependent on or looking for outside capital, tracking these metrics will allow you to iterate on your exponential business solutions, fix problem areas that are impacting positive growth and make more reliable projections.
Any change will be relatively much more significant off of a small absolute base. It can be tempting to use MoM growth in the early days of your business but try to avoid this. Once your business scales, you will probably struggle to maintain those initially artificially high growth figures and who wants to show that their growth rates are progressively decreasing? If you have secured funding through venture capital or angel investors, or are trying to do so, it is a better strategy to only introduce growth figures once you have scaled past a certain size.
So, we have already established that compound growth rates flatten your monthly growth over a set time frame into a constant percent. If you have large fluctuations in your monthly growth rates, you could choose to represent your compound growth rate as a range to be more accurate for reporting to investors or your board.
That is a misleading figure because, at a monthly level, the growth rate is decreasing. It always comes out in the end. If you find that your growth is decreasing in a linear way and is not exponential, use that insight to dig into why this is and find ways to build a better growth model. Depending on your business model, you will have different key KPIs that are directly related to revenue and growth. Keep your focus on the metrics that matter. Some metric mistakes to avoid are:. So, we know that you can input MoM data into your CMGR formula which then represents the growth that has taken place over a certain time frame and flattens the fluctuations between months.
But, if you are trying to work backward to derive the growth difference of a certain month or months based on your CMGR, chances are there will be a massive difference in what you get out and what the original individual MoM was. Using Excel or Google Sheets is a great way to work out your growth rate quickly and easily. The errors to avoid are:. Month-over-Month growth formulas in Google Sheets. Irrespective of your business type, model, or stage tracking the growth of key KPIs is invaluable data to have access to.
Planning Analysis: Calculating Growth Rates. The percent change from one period to another is calculated from the formula:. The annual percentage growth rate is simply the percent growth divided by N, the number of years. In , the population in Lane County was , This grew to , in What is the annual percentage growth rate for Lane County?
The population of Lane County grew 12 percent between and or at an rate of 1.
