Farm Return on Investment Calculator (30 Years)

Calculate return on investment as a percentage. This farm version uses a 30-year planning term as its starting point.

The Return figure is the total percentage gain over the whole 30 years, so a positive value means the final value is higher than the amount invested, and the same percentage spread over a longer period means a slower yearly pace than the same percentage over a shorter period.

Formula

Return equals final value minus invested amount, divided by invested amount, times 100.

How it works

A positive return means the final value is higher than the amount invested.

Worked example

Amount invested $10,000, final value $15,000, term 30 years. First, the gain is $15,000 minus $10,000, which is $5,000. Using the page formula, return is $5,000 divided by $10,000, times 100, which is 50.00%. That is the total return over the whole 30 years, not a yearly rate. As an illustration only, not the output of this page, the annualised rate behind the same result is about 1.36% a year, because $15,000 divided by $10,000 is 1.50, and the 30th root of 1.50 is about 1.0136. Over 30 years the yearly pace is barely above 1%: a gain of half the original sum across three decades is, in real terms, likely to have trailed rising farm costs. For farm planning this is a warning, not a success story: a 30-year return should prompt a hard look at whether the money could have worked harder elsewhere.

Who this term suits for a farm household: a farm household looking back on land bought or improved about 30 years ago, and asking whether a $5,000 gain over that whole working period really counts as growth, or whether the land simply became more expensive to run.

FAQs

What is a good ROI?
There is no single good figure. Compare returns over the same period and with the same risk before deciding.

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 $5,000 gain on $10,000 over 30 years a good result for a farm investment?
On its own, no. As an illustration only, it is about 1.36% a year, which is a slow pace over 30 years, and it is before fees, taxes and the rising cost of feed, fuel and labour.

Why does 1.36% a year matter more than the 50.00% headline at 30 years?
Because the headline hides the time taken. A 50.00% gain sounds large, but spread over 30 years it is a small yearly step, and yearly steps are what a farm family actually lives on.

What would make a 30-year farm return misleading?
Ignoring the costs paid along the way: maintenance, repairs, taxes and the price of replacing equipment. The page figure counts none of those, so the true kept gain is lower than $5,000.
