Shop Return on Investment Calculator (20 Years)

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

This Return is the total gain over the whole period as a percentage of the amount invested, not a yearly rate; a positive figure means the final value is higher than the amount invested.

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 equals $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 invested amount and the final value decide the answer.

As an illustration only, not the output of this page, the steady yearly rate that would grow $10,000 to $15,000 over 20 years, if growth were perfectly even every year, is 2.05% a year. The simple average, 50.00% divided by 20, is 2.50% a year, which ignores compounding and overstates the steady rate. The illustration is there so the same 50.00% total can be judged honestly over different lengths of time.

Who this term suits for a shop owner: a shop planning a long lease or a full equipment-replacement cycle, such as refrigeration, ovens, or a delivery vehicle, and checking a 20-year return before committing to another long stretch.

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 shop 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 shop?
Because it is only the smoothed yearly version of a 50% total gain over 20 years. Judged as a yearly rate it looks small, but the page output is the total gain, and the two numbers answer different questions.

What shop costs does a 20-year ROI leave out?
Anything not inside the invested amount or the final value: rent rises, wage rises, stock waste, repairs, fees, and taxes. Over 20 years those can easily matter more than the headline percentage.

Should a 20-year ROI guide a new shop purchase?
Only as one check among others. A single 50% figure over 20 years says nothing about cash flow in any single year, and a shop that cannot pay its monthly bills will not survive to enjoy a 20-year return.
