Shop Compound Annual Growth Rate Calculator (40 Years)

Calculate compound annual growth over a period. This shop version uses a 40-year planning term as its starting point.

The CAGR result gives the steady yearly rate that would turn the starting value into the ending value over 40 years, so even a small percentage can add up to a large total change when it compounds across four decades.

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 40 years. Using the page formula, CAGR equals $20,000 divided by $10,000, to the power of one over 40, minus one, which is 1.75% 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 40 years if growth were perfectly even every year.

For comparison, the simple average divides the 100% total gain by 40 years, which is 2.50% a year. That figure ignores compounding and overstates the steady rate, which is why CAGR, at 1.75% 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: nobody as an ordinary shop plan, because a 40-year horizon is a whole working lifetime. Its use is as a warning: a tiny steady rate still doubles a value over 40 years, but it says nothing about the decades in between.

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.

How can only 1.75% a year double a shop value?
Forty years of compounding: even a small rate, applied to a growing base every year, doubles the starting value over a lifetime of trading.

Does a 40-year rate of 1.75% a year beat shop inflation?
Almost certainly not on its own. Over 40 years, rents, wages, and stock costs usually rise far faster than 1.75% a year.

Is a 40-year shop growth figure a plan for the next 40 years?
No. It describes a past doubling, smoothed into one number. No shop, lease, or high street stays still for 40 years.
