Farm Return on Investment Calculator (35 Years)

Calculate return on investment as a percentage. This farm version uses a 35-year planning term as its starting point.

The Return figure is the total percentage gain over the whole 35 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 35 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 35 years, not a yearly rate. As an illustration only, not the output of this page, the annualised rate behind the same result is about 1.17% a year, because $15,000 divided by $10,000 is 1.50, and the 35th root of 1.50 is about 1.0117. Over 35 years the yearly pace is very small, and the original investment has probably changed hands, changed use, or been partly replaced several times. For farm planning this is a legacy check: a 35-year figure belongs to the history of the farm, not to a decision about next season.

Who this term suits for a farm household: a farm family tracing a long-held asset, such as a woodland block or a farmhouse plot bought about 35 years ago, and checking what a $5,000 gain over that lifetime really means once a generation of upkeep is counted.

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.

Why does the annual rate fall to 1.17% at 35 years even though total return is unchanged?
Because the same $5,000 gain is divided over more years: as an illustration only, 1.50 to the power of one over 35 is about 1.0117, so the yearly pace drops even though the 50.00% total does not move.

How do long gaps without a major farm decision affect a 35-year reading?
They make it stale. A figure that spans 35 years averages across whole price cycles and changes in farming itself, so it says little about what the same money would earn today.

Should a 35-year farm return be compared with a shorter, safer reserve?
Yes, always compare over the same period and with the same risk. A 35-year gain cannot fairly be set against a 5-year gain, because the time and the risks are entirely different.
