Shop Compound Annual Growth Rate Calculator (30 Years)

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

The CAGR result shows the single steady yearly rate that would grow the starting value into the ending value across 30 years, smoothing out any uneven years along the way, so it describes average pace rather than the growth seen in any one year.

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. Using the page formula, CAGR equals $20,000 divided by $10,000, to the power of one over 30, minus one, which is 2.34% a year. That is the calculator's own result for these defaults, and it is the steady yearly rate that would grow $10,000 to $20,000 over 30 years if growth were perfectly even every year.

For comparison, the simple average divides the 100% total gain by 30 years, which is 3.33% a year. That figure ignores compounding and overstates the steady rate, which is why CAGR, at 2.34% a year, is lower. All figures are estimates for planning only, not financial advice, as the pages' existing disclaimer already states.

Who this term suits for a shop owner: a shop tied to a 30-year premises commitment, such as a long commercial mortgage, or a shopkeeper comparing the value of the business at the start and end of a full career.

FAQs

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

Is this shop 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.

What does 2.34% a year over 30 years tell a shop owner?
That the value doubled over a working lifetime at a very gentle yearly pace. It is a summary of the past, not a promise about the next 30 years.

Why compare CAGR with the simple average of 3.33% a year?
The simple average overstates the steady rate because it ignores compounding. CAGR is the rate that actually reproduces the doubling when compounded.

Should a 30-year shop growth rate guide a new shop purchase?
No, not alone. Check current profit, lease length, repair liabilities, and local competition before paying for a business on the strength of a 30-year rate.
