Business Compound Annual Growth Rate Calculator (30 Years)

Calculate compound annual growth over a period. This business version uses a 30-year planning term as its starting point.

The CAGR is the steady yearly growth rate that would take the starting value to the ending value over 30 years, smoothing uneven yearly growth into a single comparable rate.

Formula

CAGR equals ending value divided by starting value, to the power of one over years, minus one.

How it works

CAGR smooths growth into a single yearly rate, even if actual yearly growth varied.

Worked example

Starting value $10,000, ending value $20,000, term 30 years. The ratio is $20,000 divided by $10,000, which is 2.00. Raise 2.00 to the power of one over 30, subtract one, and multiply by 100: the compound annual growth rate is 2.34%. That means the business value would need to grow by about 2.34% every single year, steadily, to double in 30 years.

Over 30 years the same doubling reads as 2.34% a year, which is slow growth by any standard: the business doubled, but over a working lifetime, and the decision that matters is whether the next 30 years should look like the last 30. These figures are nominal, before inflation, fees, and tax, and actual yearly growth will have varied; CAGR smooths it into one rate.

Who this term suits for a business: a generational business weighing a long lease or a large premises investment: a 30-year CAGR of 2.34% warns against assuming fast future growth, so a long commitment should be justified by current profit and demand, not by the old growth rate.

FAQs

What does CAGR mean?
CAGR is the steady yearly growth rate that would take a starting value to an ending value.

Is this business calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Is doubling in 30 years a good result for a business?
It depends on the market. In a mature, slow market it is respectable, but in a fast-growing market it means the business lost share, because competitors likely grew much faster over the same 30 years.

Why does 2.34% a year matter more than the 100% headline at 30 years?
Because the headline hides the time taken. One hundred percent over 30 years is only about 2.34% a year, and that yearly pace is what you compare with inflation, interest rates, and rival growth.

What would make a 30-year CAGR misleading?
Survivorship and asset sales: only businesses that survived 30 years report such a figure, and selling land, buildings, or a division can inflate the ending value without the trading business growing.
