Shop Compound Annual Growth Rate Calculator (20 Years)

Calculate compound annual growth over a period. This shop version uses a 20-year planning term as its starting point.

In real terms, the CAGR result is the steady yearly growth rate that would take the starting value to the ending value over 20 years, smoothing out any uneven growth along the way; it describes the average pace of growth, not the growth in any single 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 20 years. Using the page formula, CAGR equals $20,000 divided by $10,000, to the power of one over 20, minus one, which is 3.53% 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 20 years if growth were perfectly even every year.

For comparison, the simple average divides the 100% total gain by 20 years, which is 5.00% a year. That figure ignores compounding and overstates the steady rate, which is why CAGR, at 3.53% 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 on a 20-year horizon, such as a family shop passed between generations, or a premises mortgage that runs for most of a working life.

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 3.53% a year low for a shop over 20 years?
It looks small, but compounded for 20 years it still doubles the value. Long, steady shop growth often looks unimpressive in any single year.

How can such a small rate double the value?
Compounding: each year growth is earned on a larger base, so the yearly amounts grow even though the rate stays at 3.53%.

What shop costs does this 20-year rate leave out?
Rent rises, refits, stock write-offs, and tax. None of these appear in a two-value CAGR unless they changed the starting or ending value.
