Shop Compound Annual Growth Rate Calculator (35 Years)

Calculate compound annual growth over a period. This shop version uses a 35-year planning term as its starting point.

The CAGR result is the even yearly rate that would carry the starting value to the ending value over 35 years, which makes it useful for comparing long periods side by side even when actual growth jumped up and down from year to 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 35 years. Using the page formula, CAGR equals $20,000 divided by $10,000, to the power of one over 35, minus one, which is 2.00% 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 35 years if growth were perfectly even every year.

For comparison, the simple average divides the 100% total gain by 35 years, which is 2.86% a year. That figure ignores compounding and overstates the steady rate, which is why CAGR, at 2.00% 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 that has traded for most of a lifetime, such as a high-street shop handed from parent to child, where the question is what decades of slow growth are really worth.

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.

Is 2.00% a year a poor result over 35 years?
In nominal terms it still doubles the value, but over 35 years even modest inflation can wipe out a 2.00% yearly gain in real terms.

Why does the rate keep falling as the term gets longer?
The total gain is fixed at 100%. Spreading the same doubling over more years of compounding always needs a smaller yearly rate.

What can distort a 35-year shop growth figure?
A low starting value after a bad year, a one-off property revaluation, or a change in what the business owns can all make the rate misleading.
