Farm Compound Annual Growth Rate Calculator (20 Years)

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

The CAGR result is the steady yearly growth rate that would turn the starting value into the ending value over 20 years, so a higher percentage means the farm value grew faster on average across that period.

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. First, the growth factor is $20,000 divided by $10,000, which is 2.00, so the value doubled. Using the page formula, CAGR is 2.00 to the power of one over 20, minus one, times 100. The 20th root of 2.00 is about 1.0353, so CAGR is about 3.53% a year. That is the calculator's own output for the page defaults. It is a smoothed average, not a claim that the farm grew by 3.53% in every single year: on a real farm some years grow fast and some stand still or fall back, and CAGR averages them into one steady rate.

Who this term suits on a farm: a farm family looking back over about 20 years, such as the value of a farm business built from a small start, land bought and improved in stages, or a dairy or cropping enterprise grown across two decades.

FAQs

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

Is this farm 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 over 20 years a poor result for a farm?
Not necessarily. It still doubles $10,000 to $20,000, just slowly, over 20 years. Whether it is good depends on what costs rose over the same 20 years, because a rate that trails rising input costs leaves the farm no better off in real terms.

Why does CAGR fall as the term gets longer for the same doubling?
Because compounding has more years to work. The same doubling needs about 14.87% a year over 5 years, about 7.18% over 10 years, and only about 3.53% over 20 years, so longer terms always lower the yearly rate for a fixed gain.

Should a 20-year farm average guide a succession plan?
It can help show long-term direction, but succession also needs current land values, debts, labour, and who will run the farm next. A 20-year average alone does not answer those questions.
