Business Return on Investment Calculator (20 Years)

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

The Return shown is the total percentage gain on the amount invested over 20 years, so a positive percentage means the final value is higher than the amount invested, and a negative percentage means it is lower.

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.

Who this term suits for a business: a family firm valuing a long lease, a supplier contract, or a brand it built over two decades, where the owner wants an honest check of what 20 years of trading actually returned on the original money.

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 business 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 headline 50.00% hides the time taken. As an illustration only, not the output of this page, the annualised rate is about 2.05% a year, which is the figure to compare with rent rises, wage rises, and the cost of borrowing over the same 20 years.

What fees or taxes could shrink a 20-year ROI?
Accountancy fees, maintenance, repairs, licence costs, and tax on profits are not in this calculator. Over 20 years even small yearly charges add up, so the real return after those costs is lower than the 50.00% shown here.

Is a 20-year horizon too long to judge one business investment?
For a single machine or campaign, yes, it is too long, because the product and the market will have changed several times. A 20-year figure is more useful as a whole-business check, for example for a premises purchase or a family firm, than for one project.
