Farm Compound Annual Growth Rate Calculator (30 Years)

Calculate compound annual growth over a period. This farm version uses a 30-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 30 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 30 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 30, minus one, times 100. The 30th root of 2.00 is about 1.0234, so CAGR is about 2.34% 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 2.34% 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 looking at a working lifetime of growth so far, such as a holding bought 30 years ago, a farm business built across a career, or woodland and long-term plantings maturing over 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 2.34% a year over 30 years a weak result for a farm?
It still doubles $10,000 to $20,000, but only over 30 years, so in yearly terms it is slow. Whether it is weak depends on costs and prices over those 30 years, which this calculator does not compare.

Why does the rate keep falling at 30 years even though the gain is unchanged?
Because the gain is fixed at a doubling while the years keep growing. Doubling over 30 years needs only about 2.34% a year, against about 7.18% over 10 years, so the yearly rate falls as the term lengthens.

Can a 30-year farm CAGR be used to value the farm today?
No, not on its own. Today's value needs current land prices, buildings, stock, machinery, and debts. A 30-year growth average is history, not a valuation.
