Farm Return on Investment Calculator (20 Years)

Calculate return on investment as a percentage. This farm version uses a 20-year planning term as its starting point.

The Return figure is the total percentage gain over the whole 20 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 20 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 20 years, not a yearly rate. As an illustration only, not the output of this page, the annualised rate behind the same result is about 2.05% a year, because $15,000 divided by $10,000 is 1.50, and the 20th root of 1.50 is about 1.0205. Over 20 years the yearly pace is low: a gain of half the original sum across two decades is barely ahead of the slow rise in farm costs. For farm planning this is a reality check: a 20-year investment must be judged on the condition of the land or asset today, not on a percentage earned long ago.

Who this term suits for a farm household: a farm that drained wet land, fenced a boundary or improved soil about 20 years ago, and is checking whether that improvement has really added $5,000 of value, or whether the land simply kept pace with its neighbours.

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 is 2.05% a year the honest way to read a 20-year 50% return?
Because the total gain is spread over 20 years: as an illustration only, 1.50 to the power of one over 20 is about 1.0205, so the yearly pace is about 2.05%. The page itself reports only the 50.00% total.

What fees or taxes could shrink a 20-year farm return?
Selling costs, tax on any gain, maintenance and the cost of replacing worn equipment. The 50.00% figure is before all of those, so the amount a farm family actually keeps will be lower.

Is a 20-year horizon too long to judge one farm investment?
For most single purchases, yes. Over 20 years prices, crops, machinery and even the farm itself change, so a 20-year return is better read as a history lesson than as a guide to the next purchase.
