Startup Return on Investment Calculator (20 Years)

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

The Return is the total percentage gained or lost on the amount invested, so it compares the final value with the amount invested in one figure, rather than showing how much was gained in any single year.

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. Using the page formula, the gain is $15,000 minus $10,000, which is $5,000. The return is $5,000 divided by $10,000, times 100, which is 50.00%. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input: only the amount invested and the final value decide the answer.

As a labelled illustration only, not a second output of this page, the steady yearly rate that would grow $10,000 to $15,000 over 20 years is 2.05% a year. That is lower than the simple average of 2.50% a year, which divides the 50% gain evenly and ignores compounding.

Who this term suits for a startup founder: an established startup deciding on a long commitment such as buying its own premises or signing a 20-year lease, where the return on past investment is only one part of a much larger decision.

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 startup 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 not a failure for a startup?
Because the 50% headline is spread over 20 years. The steady yearly rate that would grow $10,000 to $15,000 over 20 years is 2.05% a year. Whether that is acceptable depends on the risk taken and what else the money could have done over 20 years.

What startup costs does a 20-year ROI leave out?
All running costs. This page counts only the invested amount and the final value, so rent, wages, stock, fees, taxes, and failed product lines are invisible in the 50.00% figure. A 20-year plan must account for them separately.

Should a 20-year ROI guide a new startup purchase?
Only as one input. A 20-year return on an old investment says little about a new purchase, which needs its own forecast of costs, sales, and risk over its own lifetime.
