Business Compound Annual Growth Rate Calculator (15 Years)

Calculate compound annual growth over a period. This business version uses a 15-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 15 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 15 years. The ratio is $20,000 divided by $10,000, which is 2.00. Raise 2.00 to the power of one over 15, subtract one, and multiply by 100: the compound annual growth rate is 4.73%. That means the business value would need to grow by about 4.73% every single year, steadily, to double in 15 years.

Over 15 years the same doubling reads as 4.73% a year: steady, unspectacular growth that fits a mature business, and the honest question is whether 4.73% kept ahead of inflation and rising operating costs across those 15 years. 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 family business or small manufacturer planning its next step: with 15 years of history, the owner can use a 4.73% CAGR to judge whether new equipment, a new product line, or a premises move is likely to lift growth above its long-run pace.

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 4.73% over 15 years a weak result for a business?
Not necessarily. For a mature business in a slow market, 4.73% a year for 15 years is steady progress, but it is weak if prices and costs rose faster, because then real growth was smaller or even negative.

What costs can eat into a 15-year CAGR?
Rent increases, wage rises, supplier price rises, taxes, and one-off repairs all reduce what the growth is worth. CAGR measures the top line here, so always read it next to profit, not instead of profit.

Should a 15-year CAGR include new product lines?
Only if you say so clearly. If growth came from buying another business or adding a new line, that is different from the original business growing, and a buyer or lender will want the two separated.
