Questions about cagr calculator
What is CAGR?
The single yearly growth rate that would take a value from its start to its end over a period of time.
Can the number of years be a fraction?
Yes, for example 2.5 years.
Why is CAGR different from the average return?
An average of yearly returns ignores compounding. CAGR reflects the real growth of the money from start to finish.
How CAGR is worked out
Divide the ending value by the beginning value, take the root for the number of years, and subtract one. Growing 10,000 to 25,000 over 5 years gives a CAGR of 20.11%. The result is the single steady yearly rate that would produce the same end value, so it can be used to compare investments of different lengths.
The table shows the rate needed to double a value over different periods.
| Years to double | CAGR needed |
|---|---|
| 5 | 14.87% |
| 7 | 10.41% |
| 10 | 7.18% |
| 15 | 4.73% |
| 20 | 3.53% |
What CAGR hides
CAGR ignores the ups and downs between the two dates. An investment that gains 50% one year and loses 20% the next ends at 12,000 from 10,000, a CAGR of 9.54% over 2 years, although neither year returned that amount.
It needs a beginning value above zero. A value that fell to nothing shows as a loss of 100%. It also assumes nothing was added or taken out during the period; if you made deposits or withdrawals, use the IRR calculator instead. The number of years can be a fraction, for example 2.5.
Using CAGR beyond investments
CAGR works for anything that grows over time, such as sales, subscribers or population. If yearly sales grew from 2,400,000 to 3,900,000 over 4 years, the CAGR is 12.91%. One yearly rate is easier to compare than two end figures.
Use it to describe the past, not to promise the future. A strong CAGR over a short run says little about the next few years, and starting or ending on an unusual year can change the result a lot.
